(Test Method)Standard Test Method for Copper Strip Corrosion by Industrial Aromatic Hydrocarbons
Standard Test Method for Copper Strip Corrosion by Industrial Aromatic Hydrocarbons
SCOPE
1.1 This test method determines the corrosiveness of industrial aromatic hydrocarbons to a copper strip.
Note 1—For a similar copper strip test applicable to other petroleum products, see Method D 130 and Test Method D 1838.
1.2 The values stated in SI units are to be regarded as the 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 hazard statements, see Section 8.
