Foreword
This standard replaces GB/T 6146-1985 "precision resistance alloys resistivity test methods."
This standard compared with GB/T 6146-1985, in addition to editing the text on the revised format, the main difference is.
--- In the scope clearly stated reference temperature of 20 ℃;
--- Resistivity units of μΩ · m;
--- Deleted the preparation of samples in Table 1, the contents of which are specified in the relevant provisions;
--- The resistance test equipment to ensure accurate measurement of the provisions of 0.001% change in resistance of the sample;
--- Specifies the test specimens having simple cross-section and does not have a simple cross-section sample size measuring instruments.
