ASTM C810-90(2016)

Standard Test Method for Nickel on Steel for Porcelain Enameling by X-Ray Emission Spectrometry (Withdrawn 2021)

SIGNIFICANCE AND USE
4.1 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 C715.  
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.  
1.3 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.
WITHDRAWN RATIONALE
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.
Formerly under the jurisdiction of Committee B08 on Metallic and Inorganic Coatings, this test method was withdrawn in April 2021. This standard is being withdrawn without replacement due to its limited use by industry.

INTRODUCTION
It is important that a nickel layer, of the proper amount, be applied to steel parts prior to applying
a —direct-onǁ covercoat porcelain enamel (i.e., no groundcoat underneath). This standard test is to
determine the amount of nickel on the steel using Xray emission spectrometry. There is also an
alternative wet chemical method –Test Method C715. In some cases both tests may be run to develop
comparative data.
