DIN EN 60475:2012-07

This International Standard is applicable as the method to be used for insulating liquids in delivery containers and in electrical equipment such as power and instrument transformers, reactors, bushings, oil-filled cables and oil-filled tank-type capacitors. This standard applies to liquids the viscosity of which at the sampling temperature is less than 1 500 cSt or mm²/s. It applies to mineral oils and non-mineral oils (such as synthetic esters, natural esters, vegetable oils or silicones). The standard does not purport to address all the safety problems associated with its use. It is the responsibility of the user of the standard to establish appropriate health and safety practices and determine the applicability of regulatory limitations prior to use. The insulating oils which are the subject of this standard should be handled with due regard to personal hygiene. Direct contact with the eyes may cause irritation. In the case of eye contact, irrigation with copious quantities of clean running water should be carried out and medical advice sought. Some of the tests specified in this standard involve the use of processes that could lead to a hazardous situation. Attention is then drawn to the relevant standard for guidance. This standard is applicable to mineral oils and non-mineral oils, chemicals and used sample containers. Attention is drawn to the fact that, some mineral oils in service may still be contaminated to some degree by PCBs. If this is the case, safety countermeasures should be taken to avoid risks to workers, the public and the environment during the life of the equipment, by strictly controlling spills and emissions. Every precaution should be taken to prevent release of mineral oil and non-mineral oil into the environment. The responsible committee is DKE/K 182 "Flüssigkeiten und Gase für elektrotechnische Anwendung" ("Fluids and gases for electrotechnical applications") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
