(Test Method)Standard Test Method for Evaluating Ceramic Floor Tile Installation Systems Using the Robinson-Type Floor Tester
Standard Test Method for Evaluating Ceramic Floor Tile Installation Systems Using the Robinson-Type Floor Tester
SCOPE
1.1 This test method covers the evaluation of ceramic floor tile installation systems, using the Robinson-type floor tester.
1.2 This test method is intended solely for evaluating complete ceramic floor tile installation systems for failure under loads and not for evaluating particular characteristics of ceramic tile, such as abrasion resistance. This test method does not claim to provide meaningful results for other than evaluating complete ceramic floor tile installation systems.
1.3 The values stated in inch-pound units are to be regarded as the standard. The metric (SI) units in parentheses are for information only.
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.
