(Test Method)Standard Test Method for Relative Resistance to Wear of Unglazed Ceramic Tile by the Taber Abraser
Standard Test Method for Relative Resistance to Wear of Unglazed Ceramic Tile by the Taber Abraser
ABSTRACT
This test method covers the establishment of an abrasive wear index by determination of the loss of weight resulting from abrasion of unglazed ceramic tile by Taber Abraser. The test method consists of mounting the tile specimens in suitable holders, attaching the mounted holders to the spindle of the Taber Abraser, and subjecting the specimens to a prescribed number of revolutions under abrasive wheels of specified coarseness and under a definite applied load. The apparatus consists of Taber abrading machine, vacuum pick-up, revolution counter, wheel refacer, and balance. The procedure of sampling and mounting the test specimen are detailed. The formula for calculating the abrasive wear index from the loss of weight due to abrasion is given.
SIGNIFICANCE AND USE
5.1 This test method provides a means to quantify the abrasion resistance of unglazed ceramic tile and may be related to end-use performance, or used to comparatively rank material performance, or both.
SCOPE
1.1 This test method covers the establishment of an abrasive wear index by determination of the loss of weight resulting from abrasion of unglazed ceramic tile. It is applicable to tile described in Definitions C242.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
