Materials and Manufacture5.1 The alloys may be made by any approved process.5.2 The material cover

16、ed by this specification shall be ofuniform quality and shall be free from dross, slag, or otherharmful contamination. The ingot shall also be reasonably freeof surface corrosion and adhering foreign matter.6. Chemical Requirements Chemical Requirements6.1 LimitsThis alloy shall conform to the requi

17、rements asto chemical composition prescribed in Table 1. Conformanceshall be determined by the producer by analyzing samplestaken at the time the ingots are made. If the producer hasdetermined the chemical composition of the metal during thecourse of manufacture, he shall not be required to sample a

18、ndanalyze the finished product.6.2 In case of dispute, the following requirements shallapply:6.2.1 Number of SamplesSamples for verification ofchemical composition shall be taken as follows:6.2.1.1 If the ingots are shipped in carload lots of the samealloy, not less than five ingots shall be taken a

19、t random fromthe carload for sampling. If the shipment is less than a carloadlot, one sample ingot shall be taken for each 10 000 lb (4 500kg) or fraction thereof. When it is deemed necessary, a samplemay be taken from each melt of 1 000 lb (450 kg) or more.6.3 Methods of SamplingSamples from ingots

20、 for deter-mination of chemical composition shall be taken in accordancewith one of the following methods:6.3.1 Samples for chemical analysis shall be taken from thematerial by drilling, sawing, milling, turning, or clipping arepresentative piece or pieces to obtain weight of preparedsample not less

21、 than 100 g. Sampling shall be in accordancewith Practice E88.6.3.2 By agreement, an optional method of sampling foranalysis may be by melting together representative portions ofeach ingot selected, and then sampling the liquid composite bycasting suitable specimens for either spectrographic or chem

22、i-cal analysis.6.3.3 Sample may also be in the form of a separately castspectrographic specimen taken from the same pour used to castthe ingot.6.4 Method of AnalysisThe determination of chemicalcomposition shall be made in accordance with suitable chemi-cal (Test Methods E 536 or Test Method E47for

23、tin) or othermethods. In case of dispute, the results secured by TestMethods E 536 and Test Method E47for tin only shall be thebasis of acceptance.7. Source Inspection7.1 If the purchaser desires that his representative inspect orwitness the inspection and testing of the product prior toshipment, su

24、ch agreement shall be made by the purchaser andproducer or supplier as part of the contract or purchase order.7.2 When such inspection or witness of inspection andtesting is agreed upon, the producer or supplier shall afford thepurchasers representative all reasonable facilities to satisfyhim that t

25、he product meets the requirements of this specifica-tion. Inspection and tests shall be conducted so there is nounnecessary interference with the producers operations.8. Rejection and Rehearing8.1 Material that fails to conform to the requirements of thisspecification may be rejected. Rejection shou

26、ld be reported tothe producer or supplier promptly and in writing. In case ofdissatisfaction with the results of the test, the producer orsupplier may make claim for a rehearing. If the rehearingestablishes that the material does not conform to the require-ments of this specification, as much of the

27、 rejected originalmaterial as possible shall be returned to the producer orsupplier.9. Identification Marking9.1 All ingots shall be properly marked for identificationwith the producers name or brand.9.2 Each bundle or skid shall be identified with the produc-ers heat, lot, or other identification m

28、ark.9.3 Each ingot, bundle or skid shall be marked with theappropriate Color Code for the alloy as per North AmericanRequirements in Practice B 908.10. Preparation for Delivery10.1 PackagingUnless otherwise specified, the ingot shallbe packaged to provide adequate protection during normalhandling an

29、d transportation. Each package shall contain onlyone alloy unless otherwise agreed upon.11.
