ASTM F1679-04e1

Standard Test Method for Using a Variable Incidence Tribometer (VIT) (Withdrawn 2006)

SCOPE
1.1 This test method covers the operational procedures for using a variable incidence tribometer (VIT) for determining the slip resistance of planar walkway surfaces or walkway surrogates (test surfaces) and can be used for footwear bottom materials and surrogates (test feet) in either the laboratory or field under dry, wet, or contaminated conditions. This test method does not address all methodological issues (for example, test surface and test foot material selection and preparation, experimental design, or report preparation).
1.2 The values stated in inch-pound units are to be regarded as the 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 and health practices and determine the applicability of regulatory limitations prior to use.
WITHDRAWN RATIONALE
This test method covers the operational procedures for using a variable incidence tribometer (VIT) for determining the slip resistance of planar walkway surfaces or walkway surrogates (test surfaces) and can be used for footwear bottom materials and surrogates (test feet) in either the laboratory or field under dry, wet, or contaminated conditions. This test method does not address all methodological issues (for example, test surface and test foot material selection and preparation, experimental design, or report preparation).
Formerly under the jurisdiction of Committee F13 on Pedestrian/Walkway Safety and Footwear, this test method was withdrawn as an active ASTM standard by action of the Committee of Standards (COS) on September 30, 2006 for failure to include an approved precision statement (violating Section A21 of the Form and Style for ASTM Standards), and for including reference to proprietary apparatus where alternatives exist (violating Section 15 of the Regulations Governing ASTM Technical Committees).
