(Test Method)Standard Test Method for Copper Strip Corrosion by Liquefied Petroleum (LP) Gases
Standard Test Method for Copper Strip Corrosion by Liquefied Petroleum (LP) Gases
SIGNIFICANCE AND USE
5.1 Copper corrosion limits provide assurance that difficulties will not be experienced in deterioration of the copper and copper-alloy fittings and connections that are commonly used in many types of utilization, storage, and transportation equipment.
SCOPE
1.1 This test method covers the detection of the presence of components in liquefied petroleum gases which can be corrosive to copper.
Note 1: For an equivalent copper strip test applicable to less volatile petroleum products, see Test Method D130.
1.2 The values stated in SI units are to be regarded as standard. 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 and health practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see 7.1, 10.3.1, and Annex A1.
