ASTM A754 Metallic Coatings on Steel by X-Ray Fluorescence

ASTM A754 test method determines the coating weight of metallic coatings such as zinc coating or zinc alloy coating on s teel sheets by using X-ray fluorescence and can be applied to the layers covered by various ASTM specifications. The test method’s final results must be expressed in either inch-pound units or SI units.... Read More

    Scope:

    ASTM A754 test method establishes a standard for calculating the weight and thickness of coatings on steel sheets by applying X-ray fluorescence or isotope measuring instruments. Zinc coating protects against corrosion. Different layer designations are formed as per the specifications of the zinc-coated steel sheet, which helps the purchaser choose the most suitable coating weight.

    Test Procedure:

    In ASTM A754, each instrument is operated such that the area of fluorescence remains between 970 and 3200 mm² for X-ray tube gauges and 3200 and 9000 mm² for isotope gauges. The traversing speed should be such that it leads to less than 1% test error, and the triple spot technique should be used to calculate coating weight. Stable temperature, accuracy, and cleanliness are to be practised.

    Specimen Size : 

    The specimen is created to the measurements specified.

    Data:

    For ASTM A754, weight is reported in SI units or Inch pound units.

    Accuracy of X-ray tube and isotope coating weight gauges, when used for determining coating weight specifications are above 1.3 oz/ft2/side [400 g/m2/side] for zinc coatings, 0.066 oz/ft2/side [20g/m2/side] for tin coatings, and 0.82 oz/ft2/side [250 g/m2/side] for aluminium coatings.

    Conclusion:

    ASTM A754 test method establishes a standard for calculating the weight and thickness of coatings on steel sheets by applying X-ray fluorescence or isotope measuring instruments.
