Check analysis limits forelements or for ranges of elements not currently listed hereinshall be as specified in the applicable material specification oras agreed upon by purcha
4、ser and supplier.1.2 In case of any conflicting requirements, the require-ments of the purchase order, the individual material specifica-tion, and this general specification shall prevail in the sequencenamed.1.3 When specifically referenced in the material specifica-tion, the buyer may elect to app

Quality Assurance Provisions5.1 SamplingFor the purpose
31、of determining conform-ance to the chemical composition requirement, each heat or lotin a shipment shall be considered separately. All samples shallbe taken from finished part or material in the condition inwhich it is received, except that all protective surface treat-ments shall be removed before
32、sampling. Sample material shallbe free from scale, grease, dirt, and other foreign materials andshall be taken in such a manner as to prevent alteration of thechemical composition of the sample. Sampling shall be inaccordance with Practice E 55 for wrought material or PracticeE 88 for cast material,
