Appendix A – ASTM Test Setup
The ASTM brush and holder is easy to install and quite versatile. This guide is intended to
help the user set up the Gardner-scrub for use with the ASTM standards. Please refer to
specific standard for a complete description of the test method.
Pictured are the parts that come with the
ASTM accessory kit. On the left is the Lily
Frame with two configurable dividers, in the
center from top to bottom are the brush
holder, brush, brush pad and brass shim. On
the right is the glass plate.
This photo shows the brush and holder. The
holder is attached to the Gardner-scrub by
removing the two acorn-head nuts on the
brush holder. Then slip the posts into the
desired holes on the carriage arm. Reattach
the nuts to retain the brush holder when the
arm is lifted.
A single brush should be mounted in the
center holes of the arm. Multiple holes are
provided to allow single, 2 brush or 3 brush
operation. The Lilly frame can be adjusted
by moving the dividers to allow various
combinations of brushes.
