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 Committee.
This test method applies to most woven and nonwoven fabrics providing they do not stretch excessively. It is not applicable to floor coverings.The values stated in either SI units or inch-pound units are to be regarded separately as the standard. Within the text, the inch-pound units are shown in parentheses. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with this test method.
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.
Test procedures of abrasion testing:
Four specimens, each of 38mm in diameter are cut by using the appropriate cutter.
Then they are mounted in the specimen holders with a circle of standard foam backing behind the fabric. The specimens must be placed flat against the mounting block.
The test specimen holders with the specimens are placed on the abradant.
A spindle is inserted through the top plate and the correct weight (usually of a size to give a pressure of 12kPa but a lower pressure of 9kPa may be used if specified) is placed on top of this.
The standard abradant should be replaced at the start of each test and also replaced after each 50,000 cycles if the test is continued beyond this number.
While the abradant is replaced it is held flat by a weight and the retaining ring is tightened.
Behind the abradant, there is a standard backing felt which is replaced at longer intervals.
After appropriate clamping of specimen on the holders, required numbers of cycles of abrasion is applied.
