Formerly under the jurisdiction of Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants, this test method was withdrawn in November 2021. This standard is being withdrawn without replacement. Test Method D1018 was originally developed in 1949 when there were few approaches for the determination of hydrogen in petroleum products. Since that time, instrumental methods have been developed for the determination of hydrogen in petroleum products, for example, Test Methods D3701, D4808, and D5291. It is the judgement of the D02.03 officers that this method is no longer needed and could not be revised to comply with the negative voter’s request without a new interlaboratory study, which would be difficult to get the required participation.
Значение и использование4.1 Knowledge of the hydrogen content of petroleum products, particularly fuels, can be helpful in assessing performance characteristics.
4.2 This test method is suitable for most laboratory applications requiring the determination of hydrogen in liquid petroleum lubricants and products.
1.1 This test method covers the determination of hydrogen in petroleum fractions that can be burned completely without smoking in a wick lamp.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 and health practices and determine the applicability of regulatory limitations prior to use.
