Quality Assurance5.1 Unless otherwise specified in
17、the contract or purchaseorder, the producer shall be responsible for the performance ofall inspections and test requirements specified herein. Unlessdisapproved by the purchaser, the producer may use his own orany other suitable facilities for the performance of the inspec-tion and test requirements
18、 specified herein. The purchaser shallhave the right to perform any of the inspections and tests setforth in this specification where such inspections are deemednecessary to confirm that the material conforms to prescribedrequirements.5.2 All testing shall be performed in accordance to appli-cable A
19、STM 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 Hollow shells shall not exceed 10 % by count in aminimum sample of 340 shot. The surface of material in shotform shall be free from a heavy oxidized coating.5.4
20、.2 The bulk density of shot shall not be less than 90lb/ft3.6. Chemical Composition6.1 LimitsThe average analysis of each lot of materialshall conform to the chemical composition limits specified inTable 1. Conformance shall be determined by the producer bytaking samples in accordance with E716 at t
21、he time ingots,bars, rods, cones, nuggets or shot are poured. The averageanalysis shall be determined from the analytical results of allsamples taken from that cast. If the producer has determinedthe chemical composition of the material during casting,sampling and analysis of the finished product sh
22、all not berequired.6.2 Methods of AnalysisThe determination of chemicalcomposition shall be made in accordance with E607, E716,E1251), and E34 or 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 co
23、ntract or purchase order.6.3.1 When lots are mixed, the certified chemical composi-tion of a composite lot shall be the weighted average 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 ba
24、tch process shall consist of that productproduced in a continuous cast from one furnace or ladle. Oncethe furnace or ladle has been alloyed 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 thatprodu
25、ct produced during a continuous cast from one furnaceduring a period of up to 24 hours. Additions of hardeners,liquid or solid material are added to the furnace during thecasting of product.6.4.3 Any manufacturing change in the furnace, castingequipment or continuity of operation, which potentially
26、affectsthe product characteristics defined by this specification shall beconsidered as the start of a new lot.6.5 When samples are taken 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 F
27、requencyThe frequency of samples takenfor determination of chemical composition shall be as follows:6.6.1 In a batch production process, samples shall be takenperiodically throughout the production of each lot. Eachsample shall be representative of approximately equal volumesof the material. The fre
28、quency of sampling shall be not lessthan one sample for every 20 % of the volume of the furnaceor ladle from which the material is being 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. E
29、achsample 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 poured with aminimum of five samples per lot.TABLE 1 Chemical LimitsNOTE 1A
30、nalysis shall be made only for copper, zinc, magnesium,silicon, and iron unless the determination of additional elements isrequired by the 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
31、 these other elements shall be determined,reported, and the total of copper, zinc, magnesium, silicon, iron, and“other elements” shall not 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” s
32、hall constitute a “substantialconcentration” and require that element to be reported.NOTE 2The following applies to all specified limits in this table: Forpurposes of determining conformance to these limits, an observed value ora calculated value obtained from analysis shall be rounded to the neares
