Specification for Tungsten and Oxide Dispersed Tungsten Electrodes for Arc Welding and Cutting Retests

If any test fails to meet the requirement, that test shall be repeated twice. The results of both retests shall meet the requirement. Specimen for retesting may be taken from the original test sample or from a new test sample. For chemical analysis, retests need only be for those specific elements that failed to meet their 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.

In the event that, during preparation or after completion of any test, it is clearly determined that prescribed or proper procedures are not followed in preparing the test specimen, or in conducting the tests, the test shall be considered invalid, without regard to whether the test is actually completed, or whether the test results meet, or fails to meet the requirement. That test shall be repeated, following proper prescribed procedures. In this case, the requirement for doubling the number of test specimen does not apply.
