Scope*1.1 This specification establishes the requirements fortough-pitch fire-refined copper wire bars, cakes, slabs, andbillets for fabricating in
3、to wrought products and ingot andingot bars for use in the manufacture of copper and copperalloy castings. This copper is not intended for electricalpurposes.1.2 Copper under this specification corresponds to thedesignation “FRTP” (UNS C12500) as shown in ClassificationB224. This copper may also be
4、used to produce other desig-nations of copper where the chemical composition limits arenot lower then those listed for C12500 in Table 1.1.3 Although this specification includes certain UNS desig-nations as described in Practice E527, these designations arefor cross reference only and are not specif
5、ication requirements.Therefore, in case of conflict, this ASTM specification shallgovern.1.4 UnitsThe values stated in inch-pound units are to beregarded as standard. The values given in parentheses aremathematical conversions to SI units that are provided forinformation only and are not considered

16、ements.7. Dimensions, Mass, and Permissible Variations7.1 A permissible variation of 65 % in weight and 614 in.(6.35 mm) in any dimension from the manufacturers pub-lished list or the purchasers specified size shall be consideredgood delivery; provided, however, that cakes may vary 63%from the liste
17、d or specified size in any dimension greater than8 in. (203.2 mm). The weight of copper in ingots and ingot barsshall not exceed that specified by more than 10 %, butotherwise its variation is not important.8. Workmanship, Finish, and Appearance8.1 Shapes intended for fabrication shall be substantia
18、llyfree of shrink holes, cold sets, pits, sloppy edges, concave tops,and similar defects in set or casting. This requirement shall notapply to ingots or ingot bars, in which physical defects are ofno consequence.9. Sampling9.1 For routine sampling, the sampling practice shall be atthe discretion of
19、the sampler.9.2 In case of dispute the lot size, portion size, and selectionof pieces shall be as follows:9.2.1 Lot SizeAn inspection lot shall consist of all piecesthe same shape and size from the same production lot orfraction thereof.9.2.2 Portion SizeThe portion shall be four or more piecesrando
20、mly selected to be representative of the lot. Should the lotconsist of less than five pieces, each piece shall be sampled.9.3 Chemical Analysis:9.3.1 In case of dispute the sample for chemical analysisshall be taken from the pieces selected in 9.2.2 and combinedinto one composite sample in accordanc
21、e with Practice E255for a product in its final form. The minimum weight of thecomposite sample shall be 150 g.9.3.2 Instead of sampling in accordance with 9.2.2, themanufacturer shall have the option of taking samples at thetime the castings are poured.9.3.2.1 When composition of the material has be
22、en deter-mined during the course of manufacture, sampling of thefinished product by the manufacturer is not required.9.3.3 The number of samples to be taken for determinationof chemical composition shall be as follows:9.3.3.1 When sampled at the time the castings are poured, atleast two samples, one
