NOTE Informative references to documents used in the preparation of this standard, and cited at the appropriate places in the text, are listed in a bibliography (see Annex B). 3 Definition For the purposes of this standard, the following definition, based on ISO 197-3, applies. 3.1 strip
32、flat rolled product of rectangular cross-section with uniform thickness from at least 0,10 mm, supplied level wound as coils, or on cores or spools, or traverse wound on cores or spools, usually with slit edges; the thickness does not exceed one tenth of the width 4 Designations 4.1 Material 4.1.1 G
33、eneral The material is designated either by symbol or number (see Table 1). 4.1.2 Symbol The material symbol designation is based on the designation system given in ISO 1190-1. NOTE Although material symbol designations used in this standard might be the same as those in other standards using the de
34、signation system given in ISO 1190-1, the detailed composition requirements are not necessarily the same. 4.1.3 Number The material number designation is in accordance with the system given in EN 1412.EN 1654:1998 4 BSI 27 March 2003 4.2 Material condition For the purposes of this standard, the foll
35、owing designations, which are in accordance with the system given in EN 1173, apply for the material condition: R. material condition designated by the minimum value of tensile strength requirement for the product with mandatory tensile strength and elongation requirements; H. material condition des
36、ignated by the minimum value of hardness requirement for the product with mandatory hardness and bending radius requirements; Y. material condition designated by the minimum value of 0,2 % proof strength requirement for the product with mandatory 0,2 % proof strength and elongation requirements; B.
37、material condition designated by the minimum value of spring bending limit for the product with mandatory spring bending limit requirements and in some cases also with bending radius requirements. Exact conversion between material conditions designated R., H., Y., B. is not possible. Material condit
38、ion is designated by only one of the above designations. 4.3 Product The product designation provides a standardized pattern of designation from which a rapid and unequivocal description of a product is conveyed in communication. It provides mutual comprehension at the international level with regar
39、d to products which meet the requirements of the relevant European Standard. The product designation is no substitute for the full content of the standard. The product designation for products to this standard shall consist of: denomination (strip); number of this European Standard (EN 1654); materi
40、al designation, either symbol or number (see Table 1); material condition designation (see Table 2); nominal dimensions (thickness width) and tolerance classes for thickness and width (A or B); strip condition “as rolled” (N) or “as flattened” (G). The derivation of a product designation is shown in
41、 the following example. EXAMPLE Strip conforming to this standard, in material designated either CuSn6 or CW452K, in material condition H180, nominal thickness 0,500 mm, tolerance class A for thickness, nominal width 199,6 mm, tolerance class A for width, in strip condition “as flattened”, shall be
42、designated as follows: EN 1654:1998 BSI 27 March 2003 5 5 Ordering information In order to facilitate the enquiry, order and confirmation of order procedures between the purchaser and the supplier, the purchaser shall state on his enquiry and order the following information: a) quantity of product r
43、equired (mass); b) denomination (strip); c) number of this European Standard (EN 1654); d) material designation (see Table 1); e) material condition designation (see 4.2 and Table 2); f) nominal thickness; g) tolerance class for thickness (see Table 3); h) nominal width; i) tolerance class for width
44、 (see Table 4); j) strip condition (N or G); k) coil size requirements: nominal inside diameter in millimetres and maximum outside diameter in millimetres, and either maximum mass in kilograms or approximate specific coil weight (mass per width) in kilograms per millimetre; l) spool size: type or di
45、mensions. NOTE It is recommended that the product designation, as described in 4.3, is used for items b) to j). In addition, the purchaser shall state on the enquiry and order any of the following, if required: m) whether edgewise curvature for strip condition “as rolled” shall be measured over a le
46、ngth of 2 000 mm (see 6.4.2.1); n) whether strip is required to meet roughness requirements R a , R zor R max.(see 6.5.2). If so, the test method and the acceptance criteria required; o) which measuring device is to be used for the determination of transverse cross bow (see 8.7); p) whether a declar
47、ation of conformity is required (see 9.1); q) whether an inspection document is required, and if so, which type (see 9.2); r) whether there are any special requirements for marking, packaging or labelling (see clause 10).
