18、 Evaluation Procedure 1) Test Method: Place 4 drops from a plastic pipette of the insect repellent or sun screen lotion on the finished surface. Place a crock cloth over the solution. Place an aluminum panel on top of the crock cloth. The panel should be slightly larger than the crock cloth. Place a
19、 500g weight on top of the panel. Allow the test to run for one hour at the specified temperature. After one hour, remove the weight and aluminum panel from the crock cloth. Peel back the crock cloth and wipe away any excess material from the sample with a damp cloth. Evaluate the sample and the cro

27、es, LLC Page 6 of 7 Test Method: 1. Soak a length of 44.5 +/- 2 mm wide duck cloth in water until saturated. Use #10 cotton duck cloth, style 426-ACT. 2. Condition a 76 x 76 mm sample of material for 10 minutes in 55 C +/- 1 C water. Remove and secure onto a 25.4 mm diameter dowel. The sample may be
28、 held in place by clamps. The material should be held taught and stationary during the test. 3. Position the cloth so it covers 180 of the sample without touching the seam. Weight the free end of the cloth with a 1.36 +/- 0.05 kg (3 lb) mass and attach the other end to the reciprocating machine. 4.
29、Ensure a smooth stroke with a length of 95 +/- 2 mm. One rise and fall of the weight equals one reciprocating stroke. The test shall run at 50 +/- 2 reciprocating strokes per minute. 5. Run the test for 1,500 reciprocating strokes at an ambient air temperature of 21 +/-3 C. 6. Keep the cloth saturat
30、ed with room temperature water to prevent the sample from overheating and to maintain a constant coefficient of friction. 7. Record the number of cycles when wear becomes apparent. Suggest checking every 500 cycles. 8. Test a total of 3 samples using a new cloth for each sample. The duck cloth can b
