ASTM D1838-21

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.  
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. For specific warning statements, see 7.1, 10.3.1, and Annex A1.  
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.

4. Summary of Test Method
4.1 A polished copper strip is immersed in approximately 100 mL of the sample and exposed at a temperature of 37.8 °C (100 °F)
for 1 h in a cylinder of suitable working pressure. At the end of this period, the copper strip is removed and rated as one of the
four classifications of the ASTM Copper Strip Corrosion Standard (ADJD0130).
5. 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.

in Fig. 1. Provide a flexible inert hose, such as one composed of aluminum or stainless steel, which permits inverting the test
cylinder as required in the procedure (see 6.1.1). The whole assembly, including the corrosion test cylinder, shall be constructed
