1 Scope
1.1 This standard covers the determination, at reduced pressures, of the boiling range for petroleum products that can be partially or completely vaporized at a maximum liquid temperature of 400℃.
Both a manual method and an automatic method are specified in this standard.
1.2 In case of dispute, the referee test method is the manual test method at a mutually agreed upon pressure.
1.3 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
1.4 This standard involves in some hazardous materials, operations and equipment, but doesn't purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
