Flash And Fire Point Test

EXPERIMENT NO. 6 FLASH AND FIRE forefront bear witness FOR ASPHALT BY CLEVELAND OPEN transfuse RELATED THEORY FLASH POINT twinkling predict is the last temperature corrected to a barometric insistency of 101.3 kPa (760 mm Hg), at which application of a test burst prohibited fathers the vapor of a specimen to ignite under turn back conditions of test. The secular is deemed to have flashed when a large flame appears and at a time propagates itself over the surface of the specimen. Note: Occasionally, particularly near the true flash point, the application of test flame will thrust the blue halo or an enlarged flame; this is not a flash and should be ignored. FIRE POINT It is the lowest temperature at which a specimen will sustain longing for 5 seconds. A flammable material is the one, which form flames, notwithstanding does not sustain fire while a burnable material is the one, which sustains fire/burning. SOURCES OF BITUMEN Bitumen is gen erally obtained from the following three sources; i) of course occurring (in due west Indies). ii) Extracted from Limestone and Sandstone (procedure adopted in USA). iii) From Oil Refineries (this is the major(ip) source of bitumen in Pakistan). ASPHALT CEMENT (AC) pave cement shall be crude asphalt or a kind of refined lucid asphalt and refined solid asphalt, fain from crude asphaltic petroleum. It shall be free from admixture with all residues obtained by the celluloid distillation of coal, coal tar or paraffin and shall be homogeneous and free from water.
