6.1.2 The sampling for chemical analysis shall be for:
(1) Solid Wires. A representative sample obtained from each heat during pouring or subsequent processing.
(2) (‘ored composite Wires and Ceramic Rods. A representative sample obtained from a melt or a tiring of a representative sample (melt button) of a lot of the product manufactured at the same time. The chemical composition can be determined by other than a melt button or as agreed by the purchaser and supplier.
6.1.3 The sample shall be analyzed by accepted analytical methods. For elements not covered by the above listed test methods, the referee test method per ASTM E34 shall be used or as otherwise agreed upon between the manufacturer and the purchaser.
6.2 Retest
6.2.1 If the results of any test fail to meet the requirement, that test shall be repeated twice. The results of both retests shall meet the requirements. Samples for retest may be taken from the original sample. For chemical analysis. retest need be only for those specific elements that failed to meet the test requirement. If the results of one or both retests fail to meet the requirement. the material under test shall be considered as not meeting the requirements of this specification for that classification.
6.2.2 In the event that, during preparation or after completion of any test, it is clearly determined that prescribed or proper procedures were not followed in preparing the test sample or in conducting the test, the test shall be considered invalid, without regard to whether the test was actually completed. or whether test results met, or failed to meet, the requirement.
