Standard Practice for Preparation of Cold-Rolled Steel Panels for Testing Paint, Varnish, Conversion Coatings, and Related Coating Products

ABSTRACT
Test
SIGNIFICANCE AND USE
4.1 The procedures described in this practice are designed to provide steel panels with a uniform and reproducible surface for testing of paint, varnish, lacquer, conversion coatings, and related products.
SCOPE
1.1 This practice covers various types of cold rolled steel panels and the procedures to be followed in their preparation for testing paint, varnish, lacquer, conversion coatings, and related products.  
1.2 The procedures are as follows:
  Procedure A—Conversion coatings (phosphates, chromates,
etc.)
Procedure B—Vapor degreasing
Procedure C—Solvent brushing
Procedure D—Solvent wiping
Procedure E—Alkaline cleaning  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.4 This standard does not purport to address 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.
