The standard method for calibrating a sound-level meter for use with the Brüel & Kjær Artificial Mastoid for bone vibrator tests entails the use of a signal generator, a precision voltmeter, and possibly a frequency counter. This equipment should be certified annually and traceable to the National Institute of Standards and Technology (NIST), and its use generally restricts calibration to a laboratory environment and requires a considerable amount of time. We have developed a simplified method for calibrating the sound-level meter by using a sound-level calibrator and microphone. Using the known sensitivities of the microphone and the artificial mastoid, the sound-level calibrator used for calibration of the microphone may also be used for calibration of the sound-level meter to measure force levels with the artificial mastoid.

A program requirement for field test temperatures that are beyond the test accelerometer operational limits of −30° F and +150° F required the calibration of accelerometers at high shock levels and at the temperature extremes of −50° F and +160° F. The purposes of these calibrations were to insure that the accelerometers operated at the field test temperatures and to provide an accelerometer sensitivity at each test temperature. Because there is no National Institute of Standards and Technology traceable calibration capability at shock levels of 5,000–15,000 g for the temperature extremes of −50° F and +160° F, a method for calibrating and certifying the Hopkinson bar with a transfer standard was developed. Time domain and frequency domain results are given that characterize the Hopkinson bar. The National Institute of Standards and Technology traceable accuracy for the standard accelerometer in shock is ±5%. The Hopkinson bar has been certified with an uncertainty of 6%.

This paper presents a method for determination the trace contents of silver, copper, iron, palladium, zinc and platinum in refined gold samples. Simultaneous inductively coupled plasma atomic emission spectrometer with radial torch position and cross flow nebulizer was used for determination. In order to compare the different calibration strategies, two sets of calibration standards were prepared. The first set was based on matrix matched calibration standards and the second was prepared without the addition of matrix material. Detection limits for matrix matching calibrations were higher for some elements than those without matrix matching. In addition, the internal standardization method was applied and experiments indicated that indium was the best option as internal standard. The obtained results for gold sample by matrix matching and matrix free calibrations were compared with the obtained results by standard addition method. The accuracy of the methods was tested performing recovery test. Recoveries for spiked sample were in the range of 90-115 %. The accuracy of the methods was also tested by analysis of certified reference material of high pure goldAuGHP1. The best results were achieved by matrix free calibration and standard addition method using indium as internal standard at wavelength of 230 nm.

Abstract An interlaboratory study was carried out to assess the performance of preformulated, preanalyzed, dry calibration milk powders designed for calibrating infrared milk analyzers. The calibration powders can be reconstituted to produce consistent calibrations within laboratories. The powders met AOAC specifications In terms of accuracy and repeatability, and provide calibrations with performance characteristics comparable to those produced with conventional calibration milks. The reconstituted solutions were shown to be stable for up to 6 h at 40°C, and can be stored under refrigerated conditions and used for repeated analyses for up to 21 days without apparent deterioration In calibration performance. In general, the calibration powders perform as well as, or better than, the conventional calibrants used by the laboratories participating in the study, and the calibrations could be switched without significantly changing the analytical results. Simulation and cross-calibration analyses indicated that the powdered calibrants produced more consistent results overall than fluid calibration milks. The powdered calibrants, as formulated, are shown to be suitable for any application requiring calibrations that meet AOAC specifications, Including payment applications. The calibration powders have the stability and performance characteristics to serve as a consistent, stable reference standard for monitoring instrument performance, and would be a useful tool for Interlaboratory standardization or accrediting payment and dairy herd analysis laboratories.

In this work, we develop an underwater echosounder and use the standard target method to calibrate the performance of the device. In the calibration experiments, a solid tungsten carbide sphere of 38mm diameter is used as a standard target for calibrating a HPCTB-200-35 echosounder (manufactured by Hangzhou Applied Acoustics Research Institute) with a working frequency of 220 kHz. Further, the measurement data and uncertainty are presented and analyzed; these results demonstrate that the standard target method can calibrate the combined transmitting-receiving response of echosounders effectively. In our calibration experiment, the combined transmitting-receiving response of HPCTB-200-35 is about 33.8 dB, and the measurement uncertainty is about 1.0 dB (k = 2).

An increasingly frequent used sample holder, the zero-background holder (ZBH), is evaluated for use in external standard calibration of powder patterns. The effectiveness of the ZBH calibration method is determined by comparison to the conventional internal- and external-standard calibration techniques. The three calibration methods are compared using the results of lattice parameter refinements of test powders, using Si as the standard. Several test materials were used in the evaluation which cover a wide range of absorption coefficients so sample transparency effects can be distinguished from sample displacement effects. Results of the calibrations clearly indicate that the ZBH method gives precision and accuracy comparable to the internal-standard method, and significantly better than the external-standard technique. In addition, the ZBH method yields substantially better results than the internal-standard method for materials with low absorption coefficients. Low-angle calibrations are also made on a ZBH using a proposed standard, silver behenate, which has peaks from 1.5° to 20° 2θ. These calibrations have shown that if care is not taken to establish a monolayer of powder on the ZBH crystal, significant errors in refined lattice parameters will result.

Reference method for simultaneous calibration of the three and more measurement standards for vertical angle measurement is developed. This method can to use for obtaining the systematic biases of the vertical angles measurements for each of the measuring standards relative of the horizontal plain was averaged from measurement results in time their calibration or comparison. For realization of the reference method was developed the autocollimationel electronic measurement standard for the automatization measurement of the vertical angles SeaLineZero_Standard™ (SLZ_S™). Summary standard deviation (k=1) of the vertical angle measurement relative the horizontal plane, from the results of their calibration by reference method, is not more 0,07ʺ…0,15ʺ. This result was obtained without the use the systematic biases, for each measurement standards, as measurements corrections (with opposite sign). The measuring standards, that were developed and researched, are necessary for obtaining the systematic biases of the vertical angle measurement for total stations and theodolites, that have the normed standard error 0,5ʺ and 1ʺ, when these instruments are calibrating.

Abstract. A highly portable calibration source of nitric oxide (NO) based on the photolysis of nitrous oxide (N2O) supplied by 8 or 16 g disposable cartridges is demonstrated to serve as an accurate and reliable transfer standard for the calibration of NO monitors in the field. The instrument provides output mixing ratios in the range 0–1000 ppb with a precision and accuracy better than the greater of 3 ppb or 3 % of the target NO mixing ratio over a wide range of environmental conditions of ambient temperature (8.5–35.0 ∘C), pressure (745–1015 mbar corresponding to 2.7–0.0 km of elevation), and relative humidity (0 %–100 % RH). The combination of the NO calibration source with a previously described ozone calibration source based on the photolysis of oxygen in air provides a new instrument capable of outputting calibrated mixing ratios of NO, ozone (O3), and nitrogen dioxide (NO2), where the NO2 is produced by the stoichiometric gas-phase reaction of NO with O3. The portable NO2/NO/O3 calibration source requires no external gas cylinders and can be used for calibrations of NO, NO2, and O3 instruments for mixing ratios up to 1000, 500, and 1000 ppb, respectively. This portable calibrator may serve as a convenient transfer standard for field calibrations of ozone and NOx air pollution monitors.

This thesis describes a study of existing calibration methods and a comparison of them, with novel calibration and sample pre-treatment methods for flame atomic absorption spectrometry (FAAS) developed by the author. A comparison of commercially available curve fitting algorithms was carried out to show how concentration errors arise and vary, due to the use of different empirical models for the calibration curve. Novel online dilution manifolds were designed. Using flow injection and continuous flow techniques, different calibration procedures were developed to allow null methods of calibration to be used and to extend the calibration range. Methods of sample pre-treatment were developed, including online dissolution and species separation, using flow injection analysis techniques. Members of the atomic spectroscopy group of the Royal Society of Chemistry were surveyed to discover calibration practices used in commercial laboratories. Respondents were asked questions on sample type, treatment and presentation, and data reduction for calibration. During the research, several papers were published and lectures given on the topics described.

Accurate temperature measurement is an essential requirement in modern aircraft data acquisition systems. Both thermocouples and Platinum resistance temperature detectors (RTD) are used for this purpose with the latter being both more accurate and more repeatable. To ensure that only the sensor limits the accuracy of a temperature measurement, end-to-end system accuracy forward of the sensor, should be significantly greater than that of the sensor itself. This paper describes a new digital signal processing (DSP) based system for providing precision RTD based temperature measurements with laboratory accuracy in an aviation environment. Advantages of the new system include, true 3-wire RTD measurement, linear temperature output, on-board ultra-precision resistance standards and transparent dynamic calibration.

This thesis describes the development and evaluation of a high-temperature combustion standard. This comprises a McKenna burner premixed flame, together with a full assessment of its temperature, stability and reproducibility. I have evaluated three techniques for high-accuracy flame thermometry: Modulated Emission in Gases (MEG), Rayleigh scattering thermometry and photo-acoustic thermometry. MEG: Analysis shows that MEG is not usable in this application because the sharp spectral features of the absorption coefficient of gases are represented within MEG theory as an average absorption coefficient over the optical detection bandwidth. A secondary difficulty arises from the lack of high power lasers operating at wavelengths that coincides with molecular absorption lines in the hot gas. Rayleigh Scattering: Applying corrections for the temperature-dependence of the scattering cross-section, it has been possible to determine the temperature of the combustion standard with an uncertainty of approximately 1%. The temperature dependence of the scattering cross-section arises from changes in the mean molecular polarisability and anisotropy and can amount to 2% between flame and room temperatures. Using a pulse Nd-YAG laser operating at 532 nm and high linearity silicon detectors, the Rayleigh scattering experimental system has been optimised. Temperatures measured over a three-month interval are shown to be reproducible to better than 0.4% demonstrating the suitability of the McKenna burner as a combustion standard. Photo-Acoustic: By measuring the transit time of a spark-induced sound wave past two parallel probe beams, the temperature has been determined with an uncertainty of approximate 1%. Flame temperatures measured by the photo-acoustic and Rayleigh scattering thermometry system show good agreement. For high airflow rates the agreement is better than 1% of temperature, but for low airflow rates, photo-acoustic temperatures are approximately 3.6% higher than the Rayleigh temperatures. Further work is needed to understand this discrepancy.

Die Nutzung von Riometern (Relative Ionospheric Opacity Meter) zur Messung relativer atmosphärischer Absorption (in dB) ist eine etablierte Methode. Hingegen ist die Messung atmosphärischer Absorption mit absolutkalibrierten Radaren in Form einer Rauschtemperatur eher selten durchgeführt worden. In dieser Arbeit werden die Möglichkeiten einer absoluten Radarkalibrierung für ein kommerzielles SKiYMET-System vorgestellt. Die gemessene QDC (Quiet Day Curve, eine Referenzkurve für ungestörte Tage) wird dabei mit Referenzdaten verglichen. Daran wird der Einfluss des Antennenmusters auf die QDC verdeutlicht und quantitativ dargestellt. Die erreichte Genauigkeit beträgt dabei ungefähr 600 K. Die kontinuierliche und stabile Beobachtung erlaubt es, die Kopplung der Ionosphäre mit der solaren Aktivität zu untersuchen, ohne den normalen Betrieb zur Meteoranalyse zu unterbrechen.
The observation of relative atmospheric absorption (in dB) using Riometers (Relative Ionospheric Opacity Meter) is a well established method. However, the measurement of atmospheric absorption as a noise temperature with absolutely calibrated radars has rarely been realized. This work demonstrates the possibilities to perform an absolute radar calibration for standard SKiYMET meteor radars. The measured QDC (Quiet Day Curve) and the comparison to a reference QDC illustrates the capability to quantify the effect of the antenna pattern. The achieved accuracy for a QDC is approximately 600 K. The high stability of the observation during normal meteor mode allows also to investigate the ionospheric response caused by the coupling of the solar activity.

SNe Ia können als Standardkerzen verwendet werden, um den Zustandsparameter der dunklen Energie w zu messen. Nachdem viele SN Ia beobachtet wurden, wird die Genauigkeit aktueller Studien durch systematische Fehler beschränkt, wobei die Flusskalibrierung (in Wellenlänge) die dominierende Fehlerquelle ist. In dieser Arbeit wird eine Möglichkeit präsentiert, das Problem mit dem “SNIFS Calibration Apparatus” (SCALA) zu lösen oder wenigstens zu verringern. Das Ziel von SCALA ist es, dass System aus Teleskop und SNIFS mit hoher Genauigkeit zu kalibrieren und diese Kalibration auf das Standardstern-Netzwerk zu übertragen und somit die Modellabhängigkeit zu unterdrücken. SCALA erzeugt 18 nahezu parallele und kolimierte monochromatische Strahlen (mit einstellbarer Wellenlänge), die Öffnungswinkel von einem Grad haben. Die Kombination dieser Strahlen leuchtet die Bildebene des UH 88, Teleskops (Universität Hawaii 88 inch Teleskop) mit einer Genauigkeit von 1% gleichmäß ig aus. SCALA wurde im Jahr 2014 installiert und ist seit 2015 im regulären Betrieb. Im in-situ Betrieb wird einer der Strahlen ständig mit einer Photodiode überwacht, die mit einer NIST-kalibrierten Photodiode kalibriert wurde. Eine zweite so kalibrierte Photodiode wird von Strahl zu Strahl bewegt, um den Helligkeitsverlauf der anderen 17 Strahlen als Funktion der Wellenlänge zu messen. Auf diese Weise sind wir in der Lage die Ausleuchtung von SCALA mit einer Genauigkeit von besser als 1% zu vermessen. Auf diese Weise kann mit der bekannten Wellenlänge des verwendeten Lichts die Transmissionskurve des SNIFS+UH 88 Systems gemessen werden. Die gemessenen systematischen Ungenauigkeiten der Messung sind kleiner als 0.7%. Der nächste Schritt besteht darin, die mit SCALA erreichte Kalibration mit einer herkömmlichen, auf Basis des Standard Stern Netzwerkes, zu vergleichen.
SNe Ia can be used as standard candles to measure the dark energy equation of state parameter, w. Having observed a good number of these objects, current studies are limited by systematic uncertainties, among which relative (color) flux calibration is dominating. This work presents a way to solve, or at least limit, the problem with the SNIFS Calibration Apparatus (SCALA). SCALA's goal is to provide high precision calibration for the “telescope+ SNIFS” system and refine the primary standard star network, to eliminate the uncertainties due to the knowledge of their models. SCALA produces 18 quasi-parallel and collimated monochromatic (and wavelength tunable) beams with opening angles of 1 degree. The combination of these beams allows us to achieve an illumination of the focal plane of the University of Hawaii 88 inches telescope (UH 88), that is flat to within 1%. SCALA was commissioned in 2014 and fully deployed in 2015. In the in-situ set up, one of the SCALA beams is constantly monitored by a photodiode (calibrated against a NIST-calibrated photodiode), which is used as flux standard to transfer the NIST-calibration to the telescope+instrument first, and the standard star spectra afterwards. We measure the overall wavelength trend of the illumination from SCALA with a precision better than 1%, by moving another of these calibrated photodiodes from beam to beam. We can hence measure relative trasmissivity curves for each SCALA beam. Therefore, we can produce throughput curves of the SNIFS+UH 88 system. The measured systematics affecting our results sum to errors smaller than 0.7%. The next step would be to compare the calibration of the system achieved with SCALA with the traditional calibration obtained by observing standard stars.

German Armed Forces had been tasked by International Military Metrology Conference (IMMC) to draft Annex C (Regulations for setting up Calibration Intervals) to the existing Standardization Agreement (STANAG) for Calibration Documentation (STANAG 4704). Setting up the calibration interval is mandatory according to ISO 10012 and ISO 9001:2008. ILAC-G24 is the guideline for the determination of calibration intervals of measuring instruments, IEC-IECEE 2007 OP-AAG010-Ed.1.1 2005-12-09 provides basic information for setting up calibration intervals for test equipment. Both standards refer to RP-1 for further information. RP-1 is very comprehensive (179 pages) and lists several methods to determine calibration intervals. Responsibility to set up calibration intervals lies within the owner of the test & measuring equipment. Most documents are only known by metrologists working in standard calibration laboratories. The new annex C to STANAG 4704 shall provide a short summary of these documents and provide guidance for the owner of the test & measuring equipment to set up calibration intervals properly.

There are several labs operating throughout the world, which does not follow a designated guideline for calculating measurement uncertainty for force calibrations done in accordance with the ASTM E74 standard. Realizing the need for a guidance document, Morehouse decided to draft this document explaining how to calculate measurement uncertainty and how uncertainty propagation for force calibration systems works. The document examines uncertainty contributors for different tiers in the calibration hierarchy. We start with tier one laboratories using primary standards which are dead weight machines and work through the uncertainty propagation through tier two or secondary laboratories and then tier three laboratories. Calibrations, repeatability studies, and other tests were performed at each tier using different types of force calibration equipment. The paper follows the uncertainty progression and answers a question of what type of calibration standard and Calibration and Measurement Capability (CMC) is needed to achieve a specific Calibration and Measurement Capability at the next tier. Through examining the various uncertainty contributors we arrive at a conclusion that several force scopes may not be realistic in their CMC claims which means they may not be able to make statements of conformance. The testing proved the importance of the reference standard in relation to overall expanded uncertainty. Deadweight primary standards are predictably the best possible reference standard. A laboratory using secondary standards—those standards calibrated by deadweight—can achieve CMC’s as low as 0.02 % of applied force if they are using several standards. Nonetheless, the downside of using several standards is that this method involves standards to be changed at least once during the calibration which often further impacts test results. Failing to account for all the uncertainty contributors at any tier and not calculating Calibration and Measurement Capability properly will influence the Unit Under Test (UUT) in several ways resulting in lower combined uncertainties and raising measurement risk levels on all instruments in the entire measurement chain.

In the world of calibration, it is best practice to use check standards to assure the quality of calibrations. The check standard is used to determine if the reference standard has drifted by an unacceptable amount from its previous calibration. This helps the calibration laboratory to meet a requirement of Section 5.9 of ISO/IEC 17025. Ideally, the check standard is equal in repeatability to the reference standard. However, in some cases this is not practical due to various issues. In these cases, an instrument should be qualified to determine if it can be used as a check standard.

Calibration is typically performed with large, expensive standards with multiple modes of operation. These standards can be expensive to ship and difficult to move around. This makes their use in field calibration both difficult and expensive. Modular instrumentation based on standard computer buses, such as PXIe, is now available with specifications which meet or exceed those needed for many calibrations. These modular instruments are typically smaller, more flexible, less expensive, and faster than the equivalent, standalone standard. This paper will analyze several common field service use cases and show the relative merits of both traditional and modular instruments as field calibration standards.
