(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
SIGNIFICANCE AND USE
This test method provides a standardized procedure for evaluating performance of ceramic floor tile installations under conditions similar to actual specific usages. It can be used to make comparisons between customary basic installation methods, to establish the influence of minor changes in a particular installation method, and to judge the merit of proposed novel methods.
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.

methods, the tile shall be set before the mortar hardens. After
proper curing, such a panel is set in place on the foundation of
the testing machine with a weak plaster. A polyethylene sheet
shall be laid between the foundation of the tester and the
plaster,sothatthemortar-basetestpanelcanbeeasilyremoved

weight of dry sand, clean and graded (Specification C144) and
one part by weight of gypsum plaster with enough potable
water to make a fairly thick slurry has been found satisfactory.
