Quality Assurance5.1 Unless otherwise specified in the contract or purchaseorder, the producer shall be responsible for the performance ofall inspections and test requirements specified herei

17、n. Unlessdisapproved by the purchaser, the producer may use his own orany other suitable facilities for the performance of the inspec-tion and test requirements specified herein. The purchaser shallhave the right to perform any of the inspections and tests setforth in this specification where such i

18、nspections are deemednecessary to confirm that the material conforms to prescribedrequirements.5.2 All testing shall be performed in accordance to appli-cable ASTM test methods.5.3 The material covered by this specification shall be freeof dross, slag, and other harmful contamination.5.4 Shot:5.4.1

20、ll conform to the chemical composition limits specified inTable 1. Conformance shall be determined by the producer bytaking samples in accordance with E 716 at the time ingots,bars, rods, cones, nuggets or shot are poured. The averageanalysis shall be determined from the analytical results of allsam

21、ples taken from that cast. If the producer has determinedthe chemical composition of the material during casting,sampling and analysis of the finished product shall not berequired.6.2 Methods of AnalysisThe determination of chemicalcomposition shall be made in accordance with E 607, E 716,E 1251), a

22、nd E34or CEN EN 14242 (ICP method).6.3 When an actual chemical analysis or a certificate ofconformance is required with a shipment, it shall be called forin the contract or purchase order.6.3.1 When lots are mixed, the certified chemical composi-tion of a composite lot shall be the weighted average

23、of thecertified chemical compositions from each lot that is containedin the composite lot.6.4 Lot DefinitionA lot shall be defined as follows:6.4.1 A “lot” in a batch process shall consist of that productproduced in a continuous cast from one furnace or ladle. Oncethe furnace or ladle has been alloy

24、ed and casting starts, nohardeners, liquid or solid material shall be added to the furnaceor ladle.6.4.2 A “lot” in a continuous process shall consist of thatproduct produced during a continuous cast from one furnaceduring a period of up to 24 hours. Additions of hardeners,liquid or solid material a

25、re added to the furnace during thecasting of product.6.4.3 Any manufacturing change in the furnace, castingequipment or continuity of operation, which potentially affectsthe product characteristics defined by this specification shall beconsidered as the start of a new lot.6.5 When samples are taken

26、at the time the molten metal ismade into shot, rod, bar, nuggets, cones or ingot, at least onesample shall be taken from each source of molten metal.6.6 Sampling FrequencyThe frequency of samples takenfor determination of chemical composition shall be as follows:6.6.1 In a batch production process,

27、samples shall be takenperiodically throughout the production of each lot. Eachsample shall be representative of approximately equal volumesof the material. The frequency of sampling shall be not lessthan one sample for every 20 % of the volume of the furnaceor ladle from which the material is being

28、poured with aminimum of three samples per lot.6.6.2 In a continuous production process, samples shall betaken periodically throughout the production of each lot. Eachsample shall be representative of approximately equal volumesof the material. The frequency of sampling shall be not lessthan one samp

29、le for every 20 % of the volume of the furnaceor ladle from which the material is being poured with aminimum of five samples per lot.6.6.3 In either the batch or continuous production processthe maximum elapsed time between determinations shall notexceed 8 hours.6.7 Sampling of Finished ProductIf it

30、 becomes necessaryto analyze finished product for conformance to chemicalcomposition limits, the method used to sample product for theTABLE 1 Chemical LimitsNOTE 1Analysis shall be made only for copper, zinc, magnesium,silicon, and iron unless the determination of additional elements isrequired by t

31、he contract or order, or the presence of other elements insubstantial concentration is indicated during the course of the analysis. Inthe latter case, the amount of these other elements shall be determined,reported, and the total of copper, zinc, magnesium, silicon, iron, and“other elements” shall n

32、ot exceed the specified amount prescribed in thelast column of the table. Unless otherwise specified in the contract ororder, 0.2 % or more of any “other element” shall constitute a “substantialconcentration” and require that element to be reported.NOTE 2The following applies to all specified limits

33、 in this table: Forpurposes of determining conformance to these limits, an observed value ora calculated value obtained from analysis shall be rounded to the nearestunit in the last right-hand place of figures used in expressing the specifiedlimit in accordance with the rounding-off method of Practi
