GB/T 21929-2008Test method for flash point by tag closed cup tester (English PDF)

What this standard covers

This standard applies to manual with Tiger and viscosity of less than 5. 5 mm 2/s automatically closed Tester 40°C, 25°C, viscosity, or less than 9. 5 mm 2/s, and a flash point of 93°C below the flash point of liquids. Viscosity at 40°C for not less than 5. 5 mm 2/s, 25°C when the viscosity is not less than 9. 5 mm 2/s, flash point of not lower than 93°C liquid under the experimental conditions and the formation of a surface film, or the tendency of a liquid containing suspended solids closed cup flash point measured using ASTM D93 assay. For the determination of diluted bitumen flash point in accordance with ASTM D1310 and ASTM D3143. This test method can be used to measure and describe the materials, product or composition under controlled laboratory conditions of the reaction heat and flame can not be used to describe or evaluate the materials under actual fire conditions, fire risk product or composition. The test results can be used as an evaluation factor offerings fire hazard, fire hazard evaluation should take into account all relevant factors and the risk of fire when the actual end use. ASTM D93, ASTM D1310, ASTM D3828, ASTM D3278 and ASTM D3941 test method. Data in SI units as standard, the value in brackets is for reference only. This standard relates to certain hazardous materials, operation and equipment, but without all the safety issues relating to this are recommendations. So it is necessary to establish appropriate safety and health practices and establish appropriate procedures before the standard user. For tips, see the special risk 8. 2, 8. 3, 9. 5, 12. 5, and review safety data sheet.
