REQUIREMENT 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.1 PENETRATION, (mm/10) 180 - 220 (ASTM D 217, unworked) 3.2 BLEED AND EVAPORATION 3.2.1 Bleed,
4、max 0.5% 3.2.2 Evaporation, max 2.0% Test Method: Approximately 10 grams of sample are weighed into the test cone. The test cone is supported in a clean, tared, 200 ml beaker and placed in a gravity convection oven at 200 C +/- 2 C for 24 hours +/- 5 minutes. Remove cone and beaker from oven and pla
5、ce in a dessicator until cool. Calculate the following: S1 - S2 % Evaporation = W x 100Where: S1= Initial weight of cone and beaker S2= Final weight of cone and beaker W = Initial weight of sample S1 - S2 % Bleed = W x 100Where: S1= Final weight of beaker 2= Initial weight of beaker W = Initial weight of sample 3.3 EXTRUSION There shall be no flow of the material after being extruded through a 1/16 in. (1.6 mm) orifice.
