ASTM C810-90(2006)

Standard Test Method for Nickel on Steel for Porcelain Enameling by X-Ray Emission Spectrometry

SIGNIFICANCE AND USE
This test method is an accurate and rapid means for measuring nickel deposits on steel sample plates and such parts that can be fitted into the X-ray spectrometer. Its accuracy extends over a wide range of nickel deposits.
SCOPE
1.1 This test method covers the measurement of the amount of nickel deposited on sheet steel during its preparation for porcelain enameling. It is an X-ray emission method used for testing sample panels or certain commercial parts.
Note 1—An alternative wet chemical method is Test Method C 715.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For a specific hazards statement, see Section 7.
