LST EN 60666-2010 矿物绝缘油中特定添加剂的检测和测定（IEC 60666:2010）

Detection and determination of specified additives in mineral insulating oils (IEC 60666:2010)

BS EN 60666:2010 矿物质绝缘油中制定添加剂的探测和测定

The methods described in this International Standard concern the detection and determination of specified additives in unused and used mineral insulating oils. The detection methods may be applied to assess whether or not a mineral insulating oil contains an additive as specified by the supplier. The determination methods are used for the quantitative determination of additives known to be present or previously detected by the appropriate detection method.

IEC 60970:2007 绝缘液体.粒子计数和大小测定用方法

This standard describes the sampling procedures and methods for the determination of particle concentration and size distribution. Three methods are specified. One uses an automatic particle size analyser, working on the light interruption principle.The other two use an optical microscope,in either the transmitted light or incident light mode,to count particles collected on the surface of a membrane filter.The optical microscope methods are described in ISO 4407. All three methods are applicable to both used and unused insulating liquids. Annex A contains an alternative sampling procedure using a syringe and Annex B reports a reference for the calibration of automatic particle counters.
