24、egulatory limitations prior to use. The insulating liquids which are the subject of this standard should be handled with due regard to personal hygiene. Direct contact with eyes may cause slight irritation. In the case of eye contact, irrigation with copious quantities of clean running water should

25、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 drawn to the relevant standard for guidance. Environment This standard involves insulating liquids, chemicals and used sample con

Every precaution should be taken to prevent the release into the environment of the insulating liquids. BS EN 61039:2008 6 61039 IEC:2008 CLASSIFIC

27、ATION OF INSULATING LIQUIDS 1 Scope This International Standard establishes the detailed classification of the N family (insulating liquids) that belongs to class L (lubricants, industrial oils and related products) in accordance with ISO 8681 and ISO 6743-99, affecting product categories that inclu

34、he main rules of the classification system that applies to petroleum products, lubricants and related products. ISO 8681 suggests, as far as possible, to choose the application field as the main principle for the classification of petroleum products, lubricants, and related products. It also suggest

35、s classifying on the basis of the product typology, e.g. fuels are classified first of all on the basis of typology and secondly on the basis of end use. The ISO classification principle is based on the allocation of a code consisting of letters and numbers for the main classes and categories of pet

36、roleum products. The complete nomination consists of: the initials “ISO”; the class of the petroleum product or related product, indicated by a letter (see Table 1), which has to be clearly separated from the other symbols; the category, indicated by a group of letters ranging from 1 to 4, the first

37、 one always identifying the family to which it belongs and the others assuming a meaning, appropriately explained in the reference standard, which depends on the particular category of concerned products; (optional) some numbers, which can be added, to complete the nomination and that have a meaning

38、 appropriately explained in the reference standard for that particular category of products. In compliance with ISO 8681, the code should have the following general form: ISO CLASS CATEGORY (eventual) NUMBERS or the short form: CLASS CATEGORY (eventual) NUMBERS 4 Classification of insulating liquids

39、 In accordance with ISO 8681, the classification system indicates the products with a nomination that includes: the abbreviation “ISO”; the class of the petroleum products or related products is indicated by a letter that in this standard has the meaning defined in Table 1; the category is indicated

40、 by four letters whose meaning is explained in 4.2; a seven-figure number that makes up the identification code (described in 4.3). 4.1 Class classification The class of petroleum products or related products is indicated by a letter having the meaning reported in Table 1. BS EN 61039:2008 8 61039 I

41、EC:2008 Table 1 Class classification of petroleum products or related products Class Indication F Fuels S Solvents and raw materials for chemical industry L Lubricants, industrial oils and related products W Waxes B Bitumen In accordance with the ISO/IEC agreement, the insulating liquids belong to c

42、lass L “lubricants, industrial oils and related products”. 4.2 Category classification The four letters identify the category, with the following meaning: First letter The first letter, which identifies the insulating liquid family, will be N: Electrical insulation (Table 1, ISO 6743-99:2002). Secon

43、d letter The second letter identifies the main application field as follows: C capacitors; T transformers and switching equipment; S switching equipment operating at temperature lower than 10 C; Y cables. NOTE 1 In order to provide an indication of fire behaviour of insulating liquids, and also wish

44、ing to benefit from the experience gained by CT 14 of CENELEC, the following parameters have been added as well as the classifications “fire point” and “low heat value”. These employ the same classification criteria as the ones used for IEC 61100:1992. Third letter The third letter identifies the ev

45、entual presence of antioxidant additives, defined as follows: U if no additives are present; T if additives are present in trace (% wt. 0,08 % wt). Fourth letter The fourth letter identifies the fire point (fire point: ISO 2592:2000) as follows: O if the fire point is 300 C; K if the fire point is 3

46、00 C; L if the fire point of the liquid is not detectable. NOTE 2 IEC TC10 usually adopts ISO 2719:2002 in order to measure the flash point using the Pensky-Martens methodology (closed cup). If the value of the flash point determined by this method is 250 C, then the product is classified with the l

47、etter “K”, and, if there is no detectable flash point, the product is classified with the letter “L”. 4.3 Identifying code To complete the nomination, a seven-figure number is added, with the following meaning: BS EN 61039:200861039 IEC:2008 9 First three figures The first three figures correspond t

48、o the last three numbers of the code that identifies the eventual IEC reference standard, using number 000 in case the IEC reference standard is missing. Fourth figure The fourth figure identifies the eventual IEC sub-classification, using number 0 if there is no sub-classification. Fifth figure The

49、 fifth figure identifies the low heat value (ASTM D240-02) as follows: 1 if the low heat value is 42 MJ/kg; 2 if the low heat value is LCSET 10 C; 3 if 10 LCSET 30 C; 4 if 30 LCSET 40 C. Seventh figure The seventh figure identifies the biodegradability of the insulating liquid, according to OECD 301:1992, method C or F, defined as follows: 0 if liquid is not biodegradable; (ThOD removed 20 %) 1 if liqu
