ASTM B455-01 pdf free.Standard Specification for Copper-Zinc-Lead Alloy (Leaded-Brass) Extruded Shapes.
For copper alloys in which zinc is specified as the remainder, either copper or zinc is permitted to be taken as thedifference between the sum of results for all elements analyzedand 100 %. When copper is so determined,that difference value shall conform to the requirements given in Table 1.6.3 When all elements specified in Table 1 are determinedfor the copper alloy UNS No. designated in the orderinginformation, the sum of the results shall be 99.5 % minimum.The temper of the product furnished to this specifica-tion,as defined in Classification B 601, shall be M20(as hotextruded).Mechanical Property Requirements8.1 Tensile Strength Requirements:The product furnished shall conform to the require-ments of Table 2 when tested in accordance with Test MethodsE8.The tension test results shall be the basis for purchaseracceptance or rejection based upon mechanical properties. When product is intended for strictly decorativepurposes and so stated in the purchase order or contract, it ispermitted under this specification for the mechanical propertyrequirements to be waived by the purchaser. Rockwell Hardness:A Rockwell hardness test offers a quick and conve-nient method of checking general conformity to temper andtensile requirements.The dimensions,contours,and tolerances shall be provided by the purchaser,by means of a drawing or othermedium,and shall be a part of the contract or purchase order.Straightness tolerances shall be subject to agreementbetween the manufacturer and the purchaser and such agree-ment shall be part of the purchase order.Lot size,portion size,and selection of sample piecesshall be as follows:An inspection lot shall be 5000 l1b (2275kg) or fraction thereof,of the same mill form,alloy,andnominal dimensions, subject to inspection at one time.The portion shall be two individualpieces of the lot selected as to be representative of the lot.10.2 Chemical Analysis:The sample for chemical analysis shall be taken inaccordance with Practice E 255 for the product in its final formfrom the pieces selected in 10.1.2 and combined into onecomposite sample. The minimum weight of the compositesample shall be 150 g.Instead of sampling in accordance with PracticeE 255, the manufacturer shall have the option of determiningconformance to chemical composition by analyzing samplestaken at the time the castings are poured. When samples are taken at the time of casting, atleast one sample shall be taken from each group of castingspoured from the same source of molten metal.Samples for All Other Tests—Samples taken for allother tests shall be taken from the sample portions selected in10.1.2 and be of a convenient size to accommodate the test andcomply with the requirements of the appropriate test method.ASTM B455 pdf download.
