GB/T 23800-2009 in English

《GB/T 23800-2009有机热载体热稳定性测定法》由TC280（全国石油产品和润滑剂标准化技术委员会）归口，TC280SC1（全国石油产品和润滑剂标准化技术委员会石油燃料和润滑剂分会）执行，主管部门为国家标准化管理委员会。
本标准规定了未使用过的有机热载体热稳定性的试验方法，包括常压下最高使用温度高于其沸点的有机热载体。本标准未对有机硅类热载体的适用性作出评价。本标准涉及某些有危险性的物质、操作和设备，无意对与此有关的所有安全问题提出建议。因此，在使用本标准之前应建立适当的安全和防护措施，并确定相关规章限制的适用性。

1 Scope

1.1 This standard specifies the test methods for the thermal stability of unused heat transfer fluids, including those whose maximum service temperature under atmospheric pressure is higher than its boiling point.
1.2 This standard does not make any assessment on the applicability of organic silicon type heat transfer fluids.
1.3 This standard involves some dangerous substances, operations and equipment, but doesn't purport to propose suggestions for all related safety concerns. Therefore, proper safety and protection measures as well as applicability controlled by relevant rules shall be established and determined before the use of this standard.
