Knowledge of the hydrogen content of petroleum products, particularly fuels, can be helpful in assessing performance characteristics.

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 the standard.

1.3This 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.
