ASTM D5305 - 18 - Standard Test Method for Determination of Ethyl Mercaptan in LP-Gas Vapor

ASTM D5305 - 18

Standard Test Method for Determination of Ethyl Mercaptan in LP-Gas Vapor

Status : Current   Published : April 2018



1.1 This test method describes a rapid and simple procedure using length-of-stain tubes for field measurement of ethyl mercaptan in the vapor phase of LP-gas systems. Although length-of-stain tubes are available to detect ethyl mercaptan concentrations in the range of 0.5 to 120 parts per million by volume, this test method is specifically applicable to systems containing 5 ppm by volume or more of ethyl mercaptan in LP-gas vapors.

Note 1:  A chromatographic technique can be used for more precise, quantitative determination of ethyl mercaptan in LP-gas.

1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.

1.3  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.

1.4  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.
