1.1 This practice covers a calibration technique based on the preparation of standards of known water content. This technique is applicable to the production of standards between 20 cm 3 /m 3 and 2000 cm 3 /m 3 water. 1.2 The values stated in SI units are to be regarded as standard. 1.2.1 Exception— The values given in parentheses are for information only. 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. 1.3.1 The user is advised to obtain LPG safety training for the safe operation of this test method procedure and related activities. 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. ====== Significance And Use ====== 3.1 This practice is intended to provide a method to calibrate moisture analyzers used on-stream or in the laboratory.
