1.1 本规范涵盖了重新定义的先前使用的石油矿物绝缘液体，用作新的和现有的电力和配电电气设备（如变压器、调节器、电抗器、充液断路器、开关设备和附属设备）的绝缘和冷却介质。 1.2 本规范旨在定义一种经过重新精制的矿物绝缘液体，该液体在功能上可互换，可与现有矿物绝缘液体混溶，与现有设备兼容，并可进行适当的现场维护 2. 在电气设备中的应用中将令人满意地保持其功能特性。本规范仅适用于任何加工前收到的再精炼矿物绝缘液体。本规范不包括现场处理的液体。 1.3 配制的再精制矿物绝缘液体可能含有添加剂，如抑制剂、钝化剂、倾点抑制剂、流量调节剂、气体倾向调节剂和其他化合物。本规范将解决其中一些问题，但不是所有问题。 供应商有责任向用户披露有关所有已知添加剂及其浓度的信息。 1.4 以国际单位制表示的值应视为标准值。本标准不包括其他测量单位。 1.5 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers rerefined previously used mineral insulating liquid of petroleum origin for reuse as an insulating and cooling medium in new and existing power and distribution electrical apparatus, such as transformers, regulators, reactors, liquid filled circuit breakers, switchgear, and attendant equipment. 1.2 This specification is intended to define a rerefined mineral insulating liquid that is functionally interchangeable and miscible with existing mineral insulating liquids, is compatible with existing apparatus, and with appropriate field maintenance 2 will satisfactorily maintain its functional characteristics in its application in electrical equipment. This specification applies only to rerefined mineral insulating liquid as received prior to any processing. Liquids that undergo treatment in-situ are not covered by this specification. 1.3 Formulated rerefined mineral insulating liquids may contain additives such as inhibitors, passivators, pour point depressants, flow modifiers, gassing tendency modifiers, and other compounds. This specification will address some of these but not all. It is the responsibility of the supplier to disclose information concerning the presence of all known additives and their concentration to the user. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 This standard does not 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
