1 Scope
1.1 This test method describes a laboratory determination of
the slump of a knife-grade, oil-base, channel glazing
com-pound
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
appro-priate safety and health practices and determine the
applica-bility of regulatory limitations prior to use.

3 Terminology
3.1 Definitions—Refer to Terminology C 717 for definitions
of the following terms: channel, glazing, compound
4 Summary of Test Method
4.1 The test glazing compound is packed flush in two
channels The compound is aged for 7 h at 1226 2°F (50 6
1.1°C) and then examined for any evidence of slump
5 Significance and Use
5.1 This test method gives an indication of the glazing
compounds resistance to slumping
6 Apparatus
6.1 Oven, gravity-convection type, controlled at 1226 4°F
(506 2°C)
6.2 Channels, aluminum, two, with inside dimensions of 9
in long by1⁄4 in wide by5⁄8in deep (230 mm long by 6 mm
wide by 15 mm deep)
6.3 Spatula for leveling the material.
6.4 “C” Clamps, small.
6.5 Panels, two, aluminum or wood, 9 in long by 21⁄2 in
wide (230 mm long by 64 mm wide)
6.6 Masking Tape.
7 Sampling
7.1 The compound should be used directly from the con-tainer as supplied by the manufacturer
8 Procedure
8.1 Tape both ends of each of the two channels with masking tape prior to the test The tape shall remain in place during testing
8.2 Pack freshly mixed compound smooth and level, as well
as flush, to the top of the channels, taking care to prevent air entrapment
8.3 Immediately after filling, place two channels in a gravity-convection oven at 1226 4°F (50 6 2°C) for a period
of 7 h Place one channel in a straight vertical position Place one channel in a straight horizontal position with the opening
of the channel facing downward (simulating the head section of
a window) The horizontal test can be done by clamping the channel across the width of the 9 by 21⁄2-in (230 by 64-mm) aluminum or wood panel with small “C” clamps The panel can
be placed in a vertical position and the channel will be in a horizontal position with the open channel slide down allowing free flow to the compound
9 Report
9.1 Upon completion of the respective conditioning periods, examine the channels and report any evidence of slumping of the compound from the aluminum channels
10 Precision and Bias
10.1 No statement is made about either the precision or bias
of this test method for measuring slump since the result merely states whether there is conformance to the criteria for success specified in the procedure
11 Keywords
11.1 channel glazing compound; knife grade; slump
