22、 gives general requirements for pressure-sensitive adhesive tapes for electrical purposes. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 454. At the time of publication, the editions indica
23、ted were valid. All normative documents are subject to revision, and parties to agreements based on this part of IEC 454 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. Members of IEC and IS0 maintain registers of current
24、ly valid International Standards. IEC 304: 1982, Standard colours for insulation for low-frequency cables and wires. IS0 472: 1988, Plastics - Vocabulary. 3 Definition For the purpose of this International Standard, the following definition applies: 3.1 pressure-sensitive adhesive tapes: Category of
25、 tapes coated on one or both faces with a pressure-sensitive adhesive which is permanently tacky at room temperature. They require no activation by water, solvent or heat to adhere to a variety of dissimilar surfaces upon contact, using only light pressure. 4 Classification and designation The tape
26、shall be classified by: a) form and nature of backing (base) material; b) temperature index of pressure-sensitive adhesive tape (4.1); c) nature of adhesive (4.2); d) the addition of “2“ at the end of the designation denotes that the tape is coated with adhesive on both sides. Particular types of ta
27、pe may be designated by using the code letters for the form and nature of backing material given in table 1, followed by the figures for temperature index and code letters for the adhesive, as indicated in 4.2.

NOTE - The temperature index, while giving guidance of the thermal ageing behaviour of the material. should not be identified with the maximum ad
31、missible service temperature of this material in an insulation system. 4.2 Adhesive The designation of the adhesive is given in table 2. 5 Appearance Tape may be transparent, translucent or opaque and be supplied coloured or not coloured. For tapes that are coloured, the colours shall be as near as
32、possible a match for the co- lours in IEC 304. Page 7 EN 60454-1 : 1994 6 Freedom from defects Each roll shall be reasonably free from telescoping and distortion. When unwound, the tape shall show negligible transfer of adhesive to the backing of the underlying turn, tearing of the backing (base), f
33、raying or tearing of threads. 7 Dimensions 7.1 Core diameter The preferred internal diameters of the cores on which the tape is rolled are approximately 26 mm and 76 mm. 7.2 Width The preferred widths of the tape are 6 mm, 9 mm, 12 mm, 15 mm, 19 mm, 22 mm, 25 mm, 30 mm, 38 mm or 50 mm. Alternative w
34、idths may be used based on agreement between purchaser and supplier. 7.2.1 Tolerance on width The width shall not deviate by more than f 1 mm for widths up to and including 19 mm and f 1,s mm for greater widths. Closer tolerances than those stated can be specified in the individual specifications sh
35、eets, if needed. 7.3 Length The preferred lengths of tape on a roll are 5 m, 10 m, 16 m, 20 m, 25 m, 33 m, 50 m, 55 m, 66 m and 82 m. The actual length shall be not less than the stated length. Other lengths may be used based on agreement between purchaser and supplier 7.4 Thickness Thicknesses are
36、specified in the individual specification sheets. 8 Minimum storage life When correctly stored in the original sealed packing at a temperature between 10 “C and 30 OC, and an r.h. between 40 % and 75 %, the tape shall comply with the requirements of this standard for a period as specified in the rel
37、evant sheet of part 3 or the declared expiry date given by the supplier. CENELEC EN*b0454-L 74 3404583 OL497bL 03T Page 8 EN WX-1 : 1994 9 Packing The individual rolls of tape shall be packed in such a manner that: a) they are reasonably protected from moisture, dust and sunlight; b) they can easily
38、 be separated; c) they are reasonably protected from damage during normal transit conditions. 10 Marking Each roll shall have the manufacturers or suppliers identification clearly marked on the core of the roll or on the roll label. Each transit pack (carton) shall have the following information cle
39、arly and indelibly marked on it: a) the number of this standard; b) the designation of the tape, in accordance with clause 4; c) the appearance of the tape, according to clause 5; d) the nominal width of the tape; e) the length of the tape on each roll; 1) the nominal thickness of the tape; g) the n
40、umber of rolls in the transit pack; h) “This side up” or a similar indication, to ensure rolls are properly oriented during storage.

46、2). crosslinked: Better solvent resistance and softening temperature than thermo- plastic type (Tp) without the need for heat treatment. Heat treatment may, how- ever, improve the solvent resistance still further. Page 11 EN 60454-1 : 1994 Annex ZA (normative) Other international publications quoted
