This specification covers seamless copper and copper-alloy rectangular waveguide tube intended for use as transmission lines in electronic equipment. Four types of material are specified having the following nominal compositions: C10200, C10300, C12000, and C22000. The copper and copper-alloy tubes shall be finished by such cold-working and annealing operations as are necessary to meet the required properties. The material shall conform to the chemical requirements specified. The material shall conform to the Rockwell hardness requirements prescribed. The test specimens of copper UNS nos. C10200, C10300, and C12000 shall be free of cuprous oxide. It is to be expected that samples of Copper UNS Nos. C10200, C10300, and C12000 shall be capable of passing the embrittlement test. It is to be expected that samples of copper UNS nos. C10200, C10300, and C12000 will conform to the prescribed electrical resistivity requirements. Samples for chemical analysis shall be taken accordingly.

ORDER

Scope

1.1 This specification establishes the requirements for seamless copper and copper-alloy rectangular tube intended for use as transmission lines in electronic equipment. Five types of material are specified having the following nominal compositions:

Significance and Use

For purposes of determining compliance with the specified limits for requirements of chemical composition, hardness, and electrical resistivity, an observed value or a calculated value shall be rounded to the nearest unit in the last right-hand place of the figures of the specified limit in accordance with the rounding method of Practice E29.
