Significance and Use
For the purpose of determining compliance with the specified limits for requirements of the properties listed in the following table, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding method of Practice E 29:
| Property | Rounded Unit for Observed or Calculated Value |
| |
Chemical composition
Hardness | nearest unit in the last right-hand place of figures of
the specified limit |
| Tensile strength | nearest ksi |
Grain size up to 0.060
mm, incl | nearest multiple of 0.005 mm |
1. Scope
1.1 This specification establishes the requirements for round, rectangular, and square copper alloy welded tube for general engineering applications.
1.2 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.
1.3 The following hazard statement pertains only to the test method described in 18.2.3, 18.2.4, 18.2.6, and 18.2.7 of this specification: 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.
