(Test Method)Standard Test Methods for Application of Emulsion Floor Polishes to Substrates for Testing Purposes
Standard Test Methods for Application of Emulsion Floor Polishes to Substrates for Testing Purposes
SIGNIFICANCE AND USE
All five of the test methods described will produce polish films from emulsion floor polishes which can be used for various performance tests. The choice of test method is left up to the individual laboratory.
SCOPE
1.1 These test methods cover procedures for application of emulsion floor polish films to suitable substrates for testing purposes. Five test methods are covered, as outlined in Section 3.
1.2 These procedures are limited to use on flat, rigid substrates mounted, if necessary, on a nonabsorbent backing.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.
1.4 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.

Application of Emulsion Floor Polishes to Substrates for
Testing Purposes
This standard is issued under the fixed designation D1436; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
