However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. 2 Normative references

41、erials 4.1 Mica paper Mica paper referred to in this specification shall comply with the requirements of IEC 60371-3-2. 4.2 Glass fabric Normally the glass fabric shall be continuous filament glass fibre made from E glass. Unless otherwise agreed to between purchaser and seller, the glass fibre shal

42、l be in the loom state and have a size content not greater than 3 % by weight. For some applications a special type of size may be necessary and any requirements shall be subject to the purchase contract. 4.3 Epoxy resin Any epoxy resin system may be used which enables the material to meet the requi

43、rements of this specification. 5 Requirements: composition and tolerances When tested by the method of Clause 7 of IEC 60371-2 the composition of the products shall lie within the limits of Tables 1 and 2 for the appropriate grade of mica paper. EN 60371-3-5:2006 8 6 Requirements for material (as re

44、ceived) 6.1 General All materials in any one consignment shall have the same properties, within the limits of this specification, throughout the length of each roll. The surfaces shall be uniform and free from defects such as bubbles, pin-holes, creases and flaws. Material supplied in rolls shall be

45、 capable of being unrolled continuously without damage, and the force required to unroll the material shall be substantially uniform. The material shall be supplied non-interleaved. Unless otherwise specified in the purchase contract the material shall be rolled with the mica surface on the outside.

46、 6.2 Width This specification contains no requirement for width of tape. However, the following widths are preferred: 10, 12, 15, 20, 25, 30, 40 and 50 mm. The maximum trimmed width of full width material and sheet normally available is 1 000 mm. The tolerance on the width of the material shall be a

47、s in Table 3. Table 3 Tolerance on width Nominal width mm Tolerance mm d 20 20 d 500 500 0,5 1,0 5,0 6.3 Thickness Measure the thickness in accordance with Clause 4 of IEC 60371-2, using the apparatus given in 4.1.1 of that standard, making 10 measurements on one thickness of material. The measured

48、values shall be in accordance with the requirements of Tables 1 and 2. 6.4 Length There is no requirement in this specification for roll length, and this shall therefore be subject to the purchase contract. For sheet material, the tolerance on length shall be the same as for width. 6.5 Cores The tap

49、e shall be supplied compactly wound on cores of 25 mm, 40 mm, 55 mm, or 76 mm inside diameter which shall be free from sharp edges. The width of the cores in relation to that of the tape shall be subject to the purchase contract. Full width material and material wider than 100 mm shall be supplied on 55 mm or 76 mm cores. 9 EN 60371-3-5:2006 6.6 Joins The number of rolls with joins shall be limited to 25 % of any one consignment.
