Abstract:

The intensity round-robin is one of a series of round-robins sponsored by the International Centre for Diffraction Data. The purpose of these round-robins is to attempt to quantify problems encountered in the acquisition, analysis and interpretation of powder diffraction data. Previous International Centre sponsored round-robins have addressed topics including: manual and automated search match methods; sample preparation methods; d-spacing accuracy; cell parameter refinement and peak profile calibration.The primary focus of the intensity round-robin was to study measured intensities obtained from modern computer controlled powder diffractometers. However, the tests were designed in such a way as to also yield information on the performance of data treatment software packages. To this end, participants were asked to submit both raw and treated data, thus allowing evaluation of, for example, the efficiency of peak hunting algorithms in finding peaks.

Abstract:

Abstract For the characterisation of materials, the aeronautical industry accesses the expertise and the support of independent test laboratories. For the execution of characterisation tests of materials it is important that the test laboratory can fulfil the requirements of the testing expertly and continuously improves knowledge related to the tests. Quality systems are very helpful in this respect. One element of quality management systems is the internal round robin tests. This paper presents a procedure of teaching new operators to carry out tests. In addition, this article underlines how the importance of interlaboratory tests for finding and eliminating mistakes made by new operators. The analysis was performed for tensile tests. This test enables the assessment of operators and significantly improves the quality of tests.

Abstract:

Last year at this conference we submitted a preliminary report on an X-ray powder diffraction round robin sponsored by the JCPDS-ICDD. This round robin was designed primarily to study the intensities of diffraction lines found by users in routine work. At that time only a portion of the data had been analyzed, and we reported initial findings on the α-Al2O3, and Zn0 /CaCO3 samples. These included studies on counting statistics, resolution, and the effect of software on intensity precision. Since that time, all the data from the round robin has been entered into Lotus 1-2-3 (*) spread-sheets and numerous additional tests have been carried out. This paper discusses some of the more interesting findings. A complete paper on all of the tests performed is in preparation for submission to the "Methods and Practices Manual" published by the JCPDS-ICDD.

Abstract:

The reliable determination of the hygric properties of porous building materials is important. In earlier round robin campaigns large discrepancies of measured hygric properties were found among different labs. Later studies indicated that differences in lab conditions and more importantly, personnel’s operation procedures and data processing methods, might have the greatest impact. To gain further insight, a new round robin campaign has been launched by KU Leuven (Belgium), to which another eight institutes contributed. A relatively stable and homogeneous ceramic brick is tested, and 3 standard tests are performed: the vacuum saturation test, the capillary absorption test and the cup test. During the campaign, two rounds of measurements are performed. In the 1st round, tests are performed according to participants’ respective experimental protocols. Next, a strict and detailed common protocol is prescribed. This paper reports on the results obtained in the 1st round of measurements. Results show that not much progress has been made since the EC HAMSTAD project: the vacuum saturation test leads to the most consistent results, while the cup test produces the largest discrepancies, most probably originating from sample sealing and humidity control.

Abstract:

Round-robin testing for two samples, Reference Sound Source in accordance with ISO 6926 and Office printer with electrophotographic engine, were executed by seven testing laboratories in Japan on 2020. All tests were executed with parallelepiped measurement surface in hemi anechoic chamber in accordance with testing standard for engineering-grade sound power determination, ISO 3744:2010. The results show that sample standard deviation for RSS is better than printer. Standard deviations for overall A-weighted sound power level for two samples are better than combined standard uncertainties calculated with reference example of standard deviations in ISO 3744 (1.5 dB for Reference Sound Source as standard deviation of operating/mounting condition is negligibly small, 1.6 dB for printer as stable operating/mounting condition 0.5 dB). This paper also indicates tips for those who would conduct round-robin testing to obtain valid results by obviating incorrect operations and malfunctions of printers or similar equipment from the experience of some round-robin tests.

Abstract:

During the course of the past ten years the International Centre for Diffraction Data has sponsored a number of “Round Robin” tests to evaluate the quality of experimental X-ray diffraction data [1-5]. The latest of this series, called the Instrument Parameter Round Robin, was designed to evaluate, among other things, relative angularly-dependent sensitivity differences between diffractometers. Previous experiments have indicated that even perfectly aligned diffractometers of the same generic type, do not necessarily give the same set of relative intensities. One objective of the round robin was to quantify the magnitude of the experimental differences between data sets, and to demonstrate a means for external calibration of diffractometers, so that digitized diffraction intensity data obtained from different instruments could be directly compared.

Abstract:

The Association for the Control of Emissions in Products for Flooring Installation, Adhesives and Building Materials (GEV) organised a round-robin test in 2017. They wanted to establish a list of recommended testing laboratories on the basis of test results. 33 laboratories from twelve countries received three spiked test products, similar to flooring adhesives and a parquet lacquer. Less variation of results was observed compared to earlier round-robin tests, but the differences between the testing laboratories were still significant. This fact inspired a discussion regarding the analytical challenges. As an example, the parameter „sum of all volatile organic compounds (VOCs) without a target value“ includes the non-identified VOCs. This round-robin test showed a relative standard deviation of 100% and more for that parameter, which questions its reliability. The performance of 16 laboratories was rated as good by GEV. Currently, a list of recommended testing laboratories for GEV emissions testing comprises eleven laboratories from two countries. These laboratories performed well in this round-robin test and presented an appropriate accreditation according to ISO/IEC 17025.

Abstract:

The Split Hopkinson Pressure Bar (SHPB) test, while widely utilised for high strain rate tests, has yet to be standardised. As an exploratory step towards developing a standard test method or protocol, a Round Robin test series has been conducted between four institutions: (i) Swinburne University of Technology, Australia (ii) University of São Paulo, Brazil, (iii) University of Cape Town, South African and (iv) Nanyang Technological University, Singapore. Each institution prepared specimens from a metallic material, and provided batches of specimens from their chosen material to the other institutions. The materials utilised in this round of testing were commercially pure copper and aluminium, magnesium alloy and stainless steel (316 grade). The intent of the first exercise is to establish the consistency of SHPB test results on nominally identical specimens at comparable elevated strain rates, conducted by different laboratories following notionally similar test procedures with some freedom in data processing. This paper presents and compares the results of the first batch of tests for copper, identifying variations between results from different laboratories. The variation between different laboratories’ results for copper is suffciently small that there is confidence in the potential to develop a draft standard in future.

Abstract:

Repetitions of the round robin test on powder diffractometer sensitivity and round robin test of intensity measurements, using two almost identical groups of participants, enabled a comparison to be made of results obtained in different tests. Two forms of corundum test samples were used: (i) sintered plates in tests A8 and A9, and (ii) powder samples in test Bl . A rough comparison of the influence of different methods of specimen preparation from the powder material in different laboratories in test Bl is thus possible with respect to the (almost) uniform sintered plates used in tests A8 and A9. The parameters under investigation were the line positions (and/or inter-planar d-spacing) and intensities of eleven reflections occurring at the 20 angles ranging from 25° to 136° for Cu Kα-radiation

Abstract:

In the last decade computer simulations of sound fields in rooms have been developed for application in research and consulting. Some programs are commercially available. Most computer models are based on geometrical room acoustics and/or on statistical (radiosity) methods, thus not including wave phenomena such as diffraction. The uncertainty of typical simulation software was investigated in an international verification test in 1994 and 1995. The results were partly promising although some programs were not as reliable as the operators expected. These round robin tests have been continued until today with simulations and measurements in a concert hall in Jönköping in Sweden. In this paper the basic algorithms of room acoustical computer simulations, the verification in round robin tests and the observed accuracy and limitations are summarised. Finally, possible improvements are discussed.

Abstract:

To establish standard working practices and further understanding of the application of X-ray fluorescence (XRF) spectroscopy to works of art and cultural heritage materials, a series of round-robin tests have been conducted biannually since 2002. In 2008 the round-robin explored the application of XRF to the study of paintings on canvas. Thirteen samples, consisting of both modern and traditional pigments on canvas, were distributed to 25 participating institutions for analysis. The samples were designed to explore common challenges encountered in the XRF analysis of painted works including peak overlaps, sum peaks, layering/shielding effects, detection of low-Z pigments, and modern pigments. The results from representative samples highlighting each topic are discussed.

Abstract:

The status of metrology for the characterization of thermoelectric generator modules (TEM) is investigated in this work by an international round robin (RR) test including twelve laboratories from nine countries on three continents. Measurements have been performed with three samples of a Bi2Te3-based commercial TEM type, which has prevailed over three competing types during previous tests on the short- and long-term stability. A comparison of temperature-dependent results is provided up to 200 °C hot side temperature for the maximum power output Pmax, the incident heat flow Q˙In (at maximum efficiency conditions), and the maximum efficiency ηmax. Data evaluation from all RR participants reveals maximum standard deviations for these measurands of 27.2% (Pmax), 59.2% (Q˙In), and 25.9% (ηmax). A comparison between RR data sets and reference data from manufacturer specifications shows high deviations of up to 46%, too. These deviations reflect the absence of measurement guidelines and reference samples and confirm the need for improvements in the standardization of TEM metrology. Accordingly, the results of the RR are presented against the background of our own investigations on the uncertainty budgets for the determination of the abovementioned TEM properties using inhouse-developed characterization facilities, which comprise reference and absolute measurement techniques for the determination of heat flow.

Full text

Abstract:

For unidirectional thermoplastic composite materials, it is preferable to use tab-less specimens in tensile tests owing to the low adhesive performance between specimens and tabs, as well as considerable warpage in laminates due to compression molding. In this study, round-robin tests are performed for unidirectional laminates in the 0° and 90° directions by two types of thermoplastic composites – carbon/polyamide 6 and carbon/polypropylene. The purpose of the round-robin test is to examine the difference between tab-bonded and tab-less specimens. Statistical analyses determined the degree to which tab-less specimens influenced their evaluation of the mechanical performance. In addition, from the detailed experiments, precisely controlled gripping force, fine roughness of grip surfaces, and a few inserted abrasive papers had significant impact on the 0° tensile strength of tab-less specimens. Based on the results, 0° tab-less strength of the proposed gripping method was shown to be almost equal to that of tab-bonded specimens recommended by the present tensile test standard.

Abstract:

A Round Robin Tests program is being undertaken within the EC MaRINET2 initiative. This programme studies the used facility influence can have on the performance evaluation of a horizontal axis tidal turbine prototype when it is operated under wave and current conditions. In this paper, we present the design of experiments that is used throughout the work programme and the results related to the flow characterisation obtained at the Ifremer wave and current circulating tank, the Cnr-Inm wave towing tank and the ocean research facility FloWave. These facilities have been identified to provide adequate geometric conditions to accommodate a 0.724 m diameter turbine operating at flow velocities of 0.8 and 1.0 m/s. The set-up is replicated in each of the facilities with exemption of the amount of flow measuring instruments. Intrinsic differences in creating wave and currents between facilities are found. Flow velocities are up to 10% higher than the nominal values and wave amplitudes higher than the target values by up to a factor of 2. These discrepancies are related to the flow and wave generation methods used at each facility. When the flow velocity is measured besides the rotor, the velocity presents an increase of 8% compared to the upstream measurements.

Abstract:

Abstract An improved management of secondary raw materials (SRM) is a crucial contribution for a circular economy and necessitates knowledge about the composition of wastes and SRM. However, this information is scarce and has to be determined with chemical analysis (CA). CA of SRM faces challenges, which can be approached by using round robin tests (RRT) to identify deviations from the “true value” of an element/molecule content. An RRT is a testing approach, which involves multiple labs to analyze one or more samples and evaluates the lab results with regard to the goal of the RRT. This article presents a systematic literature review and investigates which purposes and which performance parameters (PP) are commonly applied in RRT of SRM. The examined literature shows that the two main purposes applied are assessment of method performance and assessment of lab performance. PP can be categorized into trueness performance parameters (TPP; assessing the deviation of a value from a reference value) and precision performance parameters (PPP; describing the variability of a data set). The main TPP identified are z score and relative deviation, the main PPP identified are standard deviation and relative standard deviation. These results offer the conclusions that RRT can be used as a bespoke method to deal with analytical effects and that the selection of PP for an RRT could be based on simplicity.

Abstract:

It is known that the split Hopkinson pressure bar (SHPB) technique has not been standardised yet. The standardised SHPB technique is necessary in order to provide guidelines for determining the intrinsic material properties. This paper examines whether consistent results can be achieved from various sets of SHPBs. Finite element analysis has been conducted using ANSYS/LS-DYNA. Numerical simulation of the round-robin tests was conducted to study the consistency of results for OFHC copper, which were obtained from three sets of apparatus, namely: 12.7 mm diameter SHPB made from the AISI 4140 steel, 13 mm diameter SHPB made from the high strength steel (HSS) and 14.5 mm diameter SHPB made from maraging steel 350 (AISI 18Ni). The current study shows that consistent flow stresses (within an acceptable error of 2.5%) were obtained from those three sets of SHPBs, which indicates the possibility of SHPB standardisation in the future.

Abstract:

4018 Background: In the beginning of 2008 the EMEA (European Medicines Agency) approved with panitumumab for the first time an EGFR (epidermal growth factor receptor) targeting therapy for patients with metastatic colorectal cancer overexpressing the EGFR and showing wildtypic sequences in the KRAS gene as a predictive biomarker. Thus, the need for assuring the quality of laboratories emerged. The German Society for Pathology in cooperation with the Federation of the German Pathologist supported by an unrestricted financial grant of Amgen Germany arranged a quality assurance system (QAS). In this context two round- robin tests were carried out which results are presented here. Methods: Collection of results from two round -robin tests and their statistical analysis applying binary classification tests. Results: Test sets of 4 histological sections from ten different cases of colorectal tumors with known mutational status of the KRAS gene were prepared for the round-robin tests. The method for the mutation detection was unrestricted. A total of 74 participants from universities (44 - 59.5 %) or other institutions (30 - 40.5 %) attended the tests. 11 participants (14.8 %) failed the test (6 universities: 13.6 %, 5 institutions: 16.6 %). For the analysis didesoxy-sequencing (DDS: 55 - 66.2 %), ARMS®-PCR (8 - 10.4 %), melting-point analysis (MPA: 7 - 9.1 %), pyrosequencing (PS: 6 - 7.8 %), hybridization (HYB: 4 - 5.2 %), or SSCP (1 - 1.3 %) were used, in which some participants (3) used more than one method. It turned out that all methods employed for the testing gave similar results when comparing the rate of correct or wrong hits or the rate of false positive detection: DDS (0.92, 0.07, 0.02), ARMS®-PCR (0.91, 0.08, 0.05), MPA (0.94, 0.06, 0.04), PS (0.95, 0.05, 0.03) or HYB (0.90, 0.10, 0.08). Conclusions: The quality of the molecular-pathological detection of KRAS mutations as precondition for an EGFR targeted therapy should be tested since about 15 % of laboratories did not meet a sufficient grade. For the mutation detection no method seemed superior. [Table: see text]

Abstract:

This classroom action research is carried out within two cycles to breed a strategy on how a Round Robin Discussion Learning Model enhance students’ critical thinking, presentation skills, confidence, and independent learning in Teaching English as a Foreign Language (TEFL) class. Pop-up quiz, teacher made-tests, classroom participation sheet, observation sheet, and rubric are utilized in the study. In addition, the collected data are then scrutinized via quantitative and qualitative doctrine. Quantitative analysis is pertained to gauge students’ critical comprehension on TEFL issues through test, quiz, and worksheet. Meanwhile, for the qualitative analysis, constant comparative method is executed to enlighten parallel variable to depict students’ presentation skills, confidence, and independent learning. The result of the study uncovers that guided question and answer session within and without the group foster students’ higher order thinking skills and the results of the tests, pop-up quizzes indicates significant upgrading from 66% into 82%. Next, round presentation in and out group activity also cultivates students’ presentation skills as well as confidence and independent learning from 65% to 85%, 67% into 77%, and from 65% to 93%. Round Robin discussion model operates well if it is supported with fixed and detailed roles of both students and teacher so that equal interactive practice is well established.

Abstract:

The Wisconsin Department of Transportation (DOT), Madison, uses a quality management program (QMP) specification for acceptance and payment of hot-mix asphalt (HMA) pavement. The QMP allows for product acceptance on the basis of contractor quality control (QC) testing when verified by the Wisconsin DOT quality verification (QV) tests. The contractor is required to do daily QC testing of mix properties in a department-certified, qualified laboratory located at the plant site. The Wisconsin DOT maintains a QV program (QVP) and conducts QV tests to determine the quality of the final product. QV and QC test results are compared, and a mix is considered acceptably verified if the two results are within specified limits. When test results do not meet these limits, the Wisconsin DOT performs referee tests to determine mixture conformance, acceptability, and payment. In 2011, the Wisconsin DOT began to see significant increases in the number of requests for referee testing as a result of wide disparities between QC and QV laboratory test results. To investigate this disparity, the department initiated a round robin laboratory test program. Results from the investigation proved to be insightful. The program was expanded and is now a key component of the Wisconsin DOT annual laboratory qualification certification program. This paper describes the program, how it is administered, how tests results are analyzed, and how nonconforming laboratories are identified. Test results obtained from the program are presented and recommendations developed for program improvements. The program details should be useful to other state highway agencies that use contractor QC tests for acceptance.

Abstract:

This paper documents the round robin testing campaign carried out on a floating wind turbine as part of the EU H2020 MaRINET2 project. A 1/60th scale model of a 10 MW floating platform was tested in wave basins in four different locations around Europe. The tests carried out in each facility included decay tests, tests in regular and irregular waves with and without wind thrust, and tests to characterise the mooring system as well as the model itself. For the tests in wind, only the thrust of the turbine was considered and it was fixed to pre-selected levels. Hence, this work focuses on the hydrodynamic responses of a semi-submersible floating foundation. It was found that the global surge stiffness was comparable across facilities, except in one case where different azimuth angles were used for the mooring lines. Heave and pitch had the same stiffness coefficient and periods for all basins. Response Amplitude Operators (RAOs) were used to compare the responses in waves from all facilities. The shape of the motion RAOs were globally similar for all basins except around some particular frequencies. As the results were non-linear around the resonance and cancellation frequencies, the differences between facilities were magnified at these frequencies. Surge motions were significantly impacted by reflections leading to large differences in these RAOs between all basins.

Abstract:

ABSTRACT The current U.S. Environmental Protection Agency (EPA) protocol for testing the effectiveness of dispersants, the Swirling Flask Test (SFT), has been found to give widely varying results in the hands of different testing laboratories. A redesign of the testing flask by eliminating the side arm, incorporating baffles in the wall of the flask, and adding a stopcock at the bottom has been adopted to improve reproducibility in the hands of different operators. The new procedure is called the Baffled Flask Test (BFT). Similar to the original SFT, the test is relatively simple, requires minimum equipment, and involves a total time span of about 2.5 hours for testing four replicates on one of the two crude oils. Before EPA can adopt the BFT as the official protocol replacing the SFT, the newly developed test must undergo independent testing in the hands of commercial laboratories. Thus, to demonstrate its repeatability and reproducibility to support its adoption as the new EPA testing protocol, a round-robin test was conducted during the spring 2000 with eight independent laboratories. The participating laboratories were provided with all the supplies needed to conduct the BFT: baffled flasks, South Louisiana and Prudhoe Bay crude oils, six dispersant products, and the artificial seawater formulation used in the protocol. The laboratories were given specific, detailed instructions on how to conduct the tests for the dispersants, including all necessary quality assurance procedures. Results were reported back to EPA and the results were analyzed statistically to quantify repeatability and reproducibility. The paper discusses the data and presents the analysis showing the method's reproducibility.
