ASTM D6273-20 天然气气味强度的标准试验方法

1.1 This test method covers the procedures for determining the threshold detection level, readily detectable level, and odor intensity of natural gas using instruments that dilute and mix the sampled natural gas with air. The mixed gas stream is then sniffed by the operator for the purpose of determining any of these parameters for odorant in a natural gas stream. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

BS ISO 23978:2020 天然气 上游地区 通过激光拉曼光谱测定成分

What is ISO 23978 about?    ISO 23978 describes a laser Raman spectroscopy method for the quantitative determination of the chemical composition of natural gas in the upstream areas.   Gas laser Raman spectrometry is a simpler and more direct analysis method than gas chromatography.   Gas laser Raman spectrometry enables rapid and simultaneous analysis of multiple gas species because each type of gas molecule emits unique light frequencies shifted from the frequency of laser light striking it. This "Raman scattering" is instantaneous and directly proportional to the number of molecules the light impacts.    Who is ISO 23978 for?    ISO 23978
