BS EN IEC 60475:2022

This standard BS EN IEC 60475:2022 Method of sampling insulating liquids is classified in these ICS categories:

• 29.040.01 Insulating fluids in general
• 29.040.10 Insulating oils

This document is applicable to the sampling procedure used for insulating liquids in delivery containers and in electrical equipment such as power and instrument transformers, reactors, bushings, oil-filled cables, oil-filled tank-type capacitors, switchgear and load tap changers (LTCs). This document applies to liquids the viscosity of which at the sampling temperature is less than 1 500 mm2/s (or cSt). It applies to mineral oils and non-mineral oils (such as synthetic esters, natural esters, vegetable oils or silicones).
