7 Del. Admin. Code § app M § 1124-A-M-5.0 - Preparation of Apparatus

5.1 Washability Machine. Level the apparatus before use and operate at 37 ± 1 cpm. (A cycle consists of a complete forward and reverse stroke.)

5.2 Sponge and Holder. Add sufficient weight to the holder in the form of metal sheets or other flat weights to give a combined weight of 1,000 g, including the dry sponge.

5.3 Test Panel. Prepare paint coated panels by the following procedure. Stir the material thoroughly and strain, if necessary, to remove all skins and particles. Draw down the coating on the panel. Apply the coating in 3 to 4 s from end to end to prevent pin holes or holidays in the film. Air dry all panels in a horizontal position for seven days in a room maintained at 73 ± 3.5°F (23 ± 2°C) and 50 ± 5% relative humidity as described in Specification D3924, or under conditions specifically applicable to the material under test. Prepare enough panels with each paint for all the projected tests. Before use, clean the top of the test panel (painted or unpainted) to be sure it is free of specks.
