Title
Standard Test Method for Residues in Liquefied Petroleum (LP) Gases

ASTM International

Publication Date:
Nov 1, 2005

Scope:

This test method covers the determination of extraneous materials weathering above 38°C that are present in liquefied petroleum gases. The extraneous materials will generally be dissolved in the LPG, but may have phase-separated in some instances.

Liquefied petroleum gases that contain certain anti-icing additives can give erroneous results by this test method.

Although this test method has been used to verify cleanliness and lack of heavy contaminants in propane for many years, it might not be sensitive enough to protect some equipment from operational problems or increased maintenance. A more sensitive test, able to detect lower levels of dissolved contaminants, could be required for some applications.

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.

A Summary of Changes section appears at the end of this standard.
