1. Scope
1. Scope 1.1 This test method covers the procedures for obtaining tribometer readings in either a laboratory or field environment using variable-angle tribometers (VAT). The VAT class of tribometer uses a test foot support apparatus that has been set in motion prior to the test foot itself contacting the test surface. The VAT applies normal and tangential force to the test surface simultaneously through the test foot. The test is repeated by increasing the angle of incidence of force application with respect to the surface under test. The incidence angle is that which is between the force applied through the test foot and a normal to the plane of the surface being tested. The incidence angle is increased until slip occurs. 1.2 This test method is conducted under dry or wet conditions. 1.3 This test method does not address all methodological issues associated with its use. 1.4 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information only. 1.5 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.
This is a non-proprietary standard for obtaining slip resistance measures by a class of tribometer that has an actuated test foot to measure slip resistance of walkway surfaces. It will be referenced by industry architectural, engineering and safety professionals and by manufacturers of walkway surface materials, code and standards writing bodies and by OSHA.
