1.4 This test method provides a procedure for determining independently the weight of coating on each surface of zinc-nickel alloy-coated sheet steel, in coating masses from 20 to 45 g/m2  (Note 0).Note 0
The upper limit of the scope has been set at 45 g/m2  because test materials with higher coating weight were not available for testing in accordance with Practice E 173. However, recognizing the simplicity of the weigh-strip-weigh technique, materials with higher coating weights can be tested following this procedure. Users of this test method are cautioned that use of it for coating weight determinations above 45 g/m 2  is not supported by interlaboratory testing.
1.5 This test method covers the determination of nickel in concentrations from 11.0 to 13.5 % in zinc-nickel coatings (). Note 2
The upper limit of the scope has been set at 13.5 % because sufficient test materials containing higher nickel were unavailable in accordance with Practice E 173. However, recognizing the calibration technique of atomic absorption spectrophotometer, materials with higher nickel content may be tested following this procedure. Users of this test method are cautioned that use of it for nickel determination out of the scope is not supported by the interlaboratory testing.
