ASTM F1678-96

Standard Test Method for Using a Portable Articulated Strut Slip Tester (PAST) (Withdrawn 2005)

SCOPE
1.1 This test method covers the operational procedures for using a portable articulated strut slip tester (PAST) for determining the slip resistance of footwear sole, heel, or related materials (test feet) against planar walkway surfaces or walkway surrogates (test surfaces) in either the laboratory or field under dry 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. The values given in parentheses are for information only.  
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WITHDRAWN RATIONALE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 portable articulated strut slip tester (PAST) for determining the slip resistance of footwear sole, heel, or related materials (test feet) against planar walkway surfaces or walkway surrogates (test surfaces) in either the laboratory or field under dry 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Formerly under the jurisdiction of Committee F13 on Pedestrian/Walkway Safety and Footwear, this test method was withdrawn in June 2005 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

9.2 Using a clean cloth or paper napkin, thoroughly wipe all
parts of the vertical and horizontal carriage rails.
9.3 Select a test foot having a suitable facing material, and
attach it to the bottom of the test foot holder, making certain
that the vertical extension extends up through the hole in the
base plate and lies behind the trigger. Also be certain that the
foot is pushed back with respect to the test foot holder as far as
it will go, so that the vertical extension is thoroughly engaged
in the single notch at the front of the test foot holder.
9.4 Remove the measuring rod from the frame clips, and
wipe it thoroughly with a clean cloth or paper napkin. Insert its
magnetic end through the index mark tube (j), pushing the rod
back until the magnet engages the head of the adjustable
carbon steel bolt attached to the carriage. While inserting the
rod, be certain that the trigger assembly is released thoroughly
by pushing the test foot as far toward the rear of the tester as
it will go. It may be necessary to back off the trigger
adjustment knob if the rod fails to slide in easily. This is
accomplished by first releasing the trigger locknut.
