1.1 These test methods describe procedures for determining the presence of cuprous oxide (Cu2O) in products made from deoxidized and oxygen-free copper.
1.2 The test methods appear in the following order: Sections Microscopical Examination without Thermal Treatment 9 – 11 Microscopical Examination after Thermal Treatment 13 – 15 Closed Bend Test after Thermal Treatment 17 – 19 Reverse Bend Test after Thermal Treatment 21 – 23
1.3 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 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.
1.5 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.
