Specification for Tungsten and Oxide Dispersed Tungsten Electrodes for Arc Welding and Cutting Rounding-off Procedure

The following will tell something about specification for tungsten and oxide dispersed tungsten electrodes for arc welding and cutting rounding-off procedure.

For purposes of determining compliance with the requirements of this Standard, the actual test values obtained shall be subjected to the rounding-off rules of ISO 31-0:1992, Annex B, Rule A or ASTM E 29. If the measured values are obtained by equipment calibrated in units other than those of this Standard, the measured values shall be converted to the units of this Standard before rounding off. If an average value is to be compared to the requirements of this Standard, rounding-off shall be done only after calculating the average. In the case where the testing standard cited in the normative references of this Standard contains instructions for rounding off that conflict with the instructions of this Standard, the rounding-off requirements of the testing standard shall apply. The rounded-off results shall fulfill the requirements of the appropriate table for the classification under test.
