Electrical oil. Standards and specifications

Electrotechnical fluids are handled through the BSI Electrical Department, of which there are four major segments. The particular segment involved for electrical oil is the General Electrical Engineering segment, and the specific committee in that segment is GEL/10. GEL/10 is responsible for some 44 standards encompassing both liquids, gases and the associated testing procedures. The relevant standards of concern are BS 148/98 and IEC 296/82. These two standards are very similar but the author highlights the major differences between the specifications. Other major standards are briefly mentioned
