1 Scope

This standard specifies the determination of a flash point at -30 ℃ ~ 70 ℃ between petroleum products and other liquids using closed cup method. This standard Precision applies only to the flash point of the sample at -5 ℃ ~ 66.5 ℃ of. This standard does not apply to water-based coatings, waterborne coatings tested according to ISO 3679. Note 1. This standard applies to the measurement and description of the test substance, or a mixture of the product to heat or flame near the property under the control of the test conditions, not to describe Fire hazard or fire or comment to the case said the actual combustion material conditions, product or mixture. But the test results can be evaluated as a factor fire one. Note 2. As a flash point for the definition of "combustible materials" and "inflammable substance" classification parameters used for the transport, storage, handling and safety provisions. Fine grading OK righteous see their specific procedures. Note 3. The flash point may indicate the possibility of a relatively less volatile or non-flammable volatile substances present in the matrix. Note 4. Due to the need for a small part of the material is easy to detect the presence of volatile, it should first be tested flashpoint after receiving the sample. Note 5. liquid halogen-containing compound may be abnormal results appear.
