ASTM D1838 Test Method for Copper Strip Corrosion by Liquefied Petroleum (LP) Gases
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.
