1.1 This specification covers limits of variation for determining acceptability of the chemical composition of cast or wrought nickel, nickel alloy, and cobaly alloy parts and material, or both, supplied by a producer. Check analysis limits for elements or for ranges of elements not currently listed herein shall be as specified in the applicable material specification or as agreed upon by purchaser and supplier.
1.2 In the case of conflicting requirements , the requirements of the purchase order, the individual material specification, and this general specification shall prevail in the sequence named.
1.3 When specifically referenced in the material specification, the buyer may elect to apply check analysis limits to determine acceptability at his final acceptance or verification procedures. Check analysis limits are not permitted or are to be used by the producer for their own ladle or ingot analysis acceptance testing.
