Standard Test Method for Nickel on Steel for Porcelain Enameling by Photometric Analysis
|Publication Date:||1 January 2000|
|ICS Code (Surface treatment):||25.220.20|
1.1 This test method covers the determination of the amount of nickel deposited on sheet steel during its preparation for porcelain enameling. It is a photometric method commonly used on production parts and is suitable for determining the heavier nickel deposits that may be obtained during the processing of steel for one-coat enameling.
Note 1--An alternative X-ray emission spectrometry method is Test Method C810.
1.2 This standard does not purport to address all of the safety problems 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.
