This year marks the 50th anniversary of ASTM International Committee E33 on Building and Environmental Acoustics which combined all ASTM activity in these areas into one committee, though work on ASTM standards for measurement of sound absorption and transmission had started prior to 1950. This presentation will discuss the history of the committee and ASTM International standards in acoustics including the leadership that has made it possible.

ASTM International publishes many standards specifically about microscopes and using microscopy. The value of these standards falls into three distinct categories. First, they can be a quick tutorial on how to perform some operation. E 1508, "Standard Guide to Quantitative Analysis by EDS" is only eight pages long and falls into this category. Second, they can be used to standardize a test and reporting method. The methods described in E 1382, "Standard Test Methods for Determining Grain Size by Semiautomatic and Automatic Image Analysis" are examples of procedures that have been agreed upon f

In 1982, the American Society for Testing and Materials (ASTM) adopted consensus standards for direct-normal and hemispherical (“global”) tilted solar terrestrial spectra (ASTM E891/E892/G159). These standard spectra were intended to evaluate photovoltaic (PV) device performance and other solar-related applications. The International Standards Organization (ISO) and International Electrotechnical Commission (IEC) adopted these spectra as spectral standards ISO 9845-1 and IEC 60904-3.

There have been two different CTOD calculations, geometric CTOD calculation in BS7448 and J-based conversion in ASTM E1290 since the ASTM International revised E1290 in 2002, and it is useful to transform one CTOD into the other CTOD. In this study, analytical and experimental investigations into the ratio of ASTM E1290-CTOD to BS7448-CTOD were carried out, and two ratios of ASTM-CTOD to BS-CTOD, R1 and R2, were characterised in terms of cleavage cracking. These two characteristic CTOD ratios are helpful in simply transforming one critical CTOD to the other.

Abstract As part of the company Geoscan Service S.R.L., I was contacted to investigate the possibility of using resistivity, refraction seismic data and MASW seismic to identify the stratification up to 15m deep so that the client could choose the type of drilling rig for installing the conductor in order to drill two water injection wells. The main problem in the choice of geophysical methods was the lack of detailed geological data for calibrating the obtained results, as the presence of groundwater, the thicknesses of the deluvial layer and the bedrock. The choice of geophysical methods and

The paper presents the results of studies aimed at defining the effect of the cooling properties of oil lubricants used in various metalworking processes. The design and a brief description of the installation are given, which allows to obtain temperature-time, temperature-velocity dependencies of various liquids. The use of this installation gives the opportunity to select lubricants according to its cooling properties, depending on the temperature range required by the process.

ABSTRACT The determination of effective daily recovery capacities for oil skimmers and pumps has been controversial and increasingly critical in recent years. Oil discharge events around the world have highlighted the importance of having effective oil spill response plans, equipment, and procedures in place and available for immediate activation. The Alaska Department of Environmental Conservation (ADEC) has determined that the standard practice of using an effective oil recovery capacity equal to 20 percent of the equipment manufacturer's rated throughput capacity over a 24-hour period is no

The importance of developing GOST standard specifications for the quality control of different grades of synthetic rubber produced in Russia, incorporating standard elastic strength and rheometric characteristics, is shown. Here, ISO and ASTM test procedures must be used, as well as positive features of Russian technical documentation. The need for and the possibility of producing and certifying home-produced reference ingredients and carbon black are also shown. The creation of a unified base of reference materials (ingredients, carbon black, etc.) will make it possible to increase the reliab

Aviation industry is considered one of the contributors to atmospheric CO2emissions. It is forced to cut off carbon dioxide emission starting 2020. Current trends in bio-jet production involve mega projects with million dollars of investments. In this study, bio-jet fuel production by blending bio-diesel with traditional jet fuel at different concentrations of bio-diesel (5, 10, 15, 20 vol. %) was investigated. This blending technique will reduce bio-jet production cost compared to other bio-jet techniques. Bio-diesel was originally produced by the transesterification of non-edible vegetable o

Abstract Computational modeling (BEM, FEM, and SEA) is often implemented at different stages of the design process to optimize manufacturing and performance parameters. Computational results are typically verified experimentally. Experimental testing standards, particularly those related to vibro-acoustic testing, are defined by various agencies such as ASTM, ANSI, and ISO. An investigation proposing a new computational methodology of analyzing the vibro-acoustic behavior of an aircraft fuselage due to the turbulent boundary layer required verification of the predictions experimentally.

Ensuring and coordination of high quality indicators of materials in the foundry industry is necessary in the development of Ukraine's economy. High quality products need to be enshrined in new national standards, harmonized with international and European standards. Thus, the purpose of this work is to analyze national and international standards for quality indicators of vermicular graphite iron and their harmonization with each other.

Quantitative microscopy methods have been utilized for the characterization of specialty metal microstructures for many years. Initially, most work was more qualitative than quantitative because all methods were manual. However, since the introduction of more capable image analyzers in the 1980s, with vastly improved computer software and hardware, automated techniques have gained favor. With the implementation of automated image analysis equipment, users have quickly realized that specimen preparation techniques must be improved and also automated.
