Standard Practice for Testing Primers and Primer Surfacers Over Preformed Metal

SIGNIFICANCE AND USE
Primers and primer surfacers may be used over many different surfaces top coated with one or more of a variety of coatings and subjected to many kinds of wear and exposure.
The selection of the tests to be used for any given product or system must be governed by experience and by the requirement agreed upon between the producer and the user.
SCOPE
1.1 This practice covers the selection and use of procedures for testing primers and primer surfacers. The test methods included are listed in Table 1.
1.2 The values stated in SI 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.
