Chemical Requi
16、rements6.1 LimitsThe alloy shall conform to the requirements 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
17、 of manufacture, it shall not be required to sample andanalyze 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:6.2.2 If the ingots are shipped in carload lots of the sa
18、mealloy, not less than five (5) ingots shall be taken at random fromthe carload for sampling. If the shipment is less than a carloadlot, one (1) sample ingot shall be taken from each 10 000 lb.4500 kg or fraction thereof. When it is deemed necessary, asample may be taken from each melt of 1000 lb. 4
