Significance and Use

For purposes of determining compliance with the specified limits for chemical composition an observed or calculated value shall be rounded as indicated in accordance with the Rounding method of Practice E29.

Property	Rounded Unit for Observed or Calculated Value

Chemical Composition	Nearest unit in the last right-hand significant digit used in expressing the limiting value

1. Scope

1.1 This specification establishes the requirements for copper nickel, ferro copper, phosphor copper, and silicon copper master alloys in ingot, shot, and waffle form to be used as addition agents for cast and wrought alloys.

1.2 Units—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.
