Amicroburner flame, not exceeding 3/16 inch in length shall be passed back and forth along thelower edge of the panel within a 2 second period. This operation shall be repeated three times at

34、3 second intervals. If the paint remover ignites, the burner flame shall be removed andobservation made to determine whether the paint remover continues to burn. Burning duration inexcess of 3 seconds after removal of the flame shall be cause for rejection.4.4.2 Viscosity. Viscosity shall be a maxim

35、um of 15 centipoises. It shall be determined atmanufacturers recommended operating temperature, using a Model LFV Brookfield Viscometer,Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-83936C(USAF)6or its equivalent in accordance with ASTM D21
