1、IDC 669.14-4 : 62-777 DEUTSCHE NORMEN August 191 I I Kennzeichnungsarten fr Stahl 1 Purpose and scope 1.1 For the identification of steels precedence is given to the provisions adopted to this effect in the quality Standards or other delivery conditions according to which the products were ordered.

2、If the conditions of delivery do not contain any provisions of this kind it may be agreed to mark the steel products. This Standard lays down the kinds of marking envisaged. The extent of marking is left to the supplier except where agreeed to the contrary. 1.2 Products may be supplied marked accord

3、ing to this Standard wen when no form of marking has been agreed. 1.3 This Standard does not cover the use of the mark or of the DIN testing and quality control symbol. Continued on pages 2 and 3 Explanations The desirability of reducing the risk of mistaken identifi- cation of materials by producer

4、s, dealers, processors or users has led to more exacting requirements regarding the marking of steel products and in the preparation of qual- ity Standards and technical conditions of delivery and is reflected in corresponding provisions of often widely dif- fering kind. Thus identification of the n

5、ecessary features is provided, for example, in the case of ribbed reinforc- ing steel (to DIN 488) by continuous rolled-in symbols throughout the bar length, in the case of boiler plate (to DIN 17 155) and pipes of high-temperature steels (to DIN 17 175) by impressed symbols in a defined area of the

6、 product, and in the case of flat products (e. g. to DIN 17 162) by stamping the plates and coils. The differences in the kinds of marking mentioned in these examples indicate that it is scarcely practicable to regulate in a general Standard, and in a binding manner, all the requirements which have

7、to be met for identify- ing steels. For the most part it is only possible to lay down appropriate provisions case by case, on the basis of intended purpose, form and dimensions of the pro- duct, in the conditions of delivery valid for the product, and as far as possible within a specified framework.

8、 This new edition of DIN 1599 has to be seen in this light. It provides a survey of the customary or technically feas- ible methods of marking steel products. It serves as a basis for agreements in cases where the conditions of delivery for the product concerned do not contain any corresponding prov

9、isions, but identification marking is nevertheless desired and ordered. In Section 4 and in Table 1 the kinds of marking con cerned are presented. Compared with the February 1964 edition (Preliminary Standard) the following additions have been made: a) Methods of marking for ingots, slabs, billets a

10、nd b) Marking by means of pre-manufactured identity c) Information on the usual position of markings on the The different shapes and colours for tie-on tags and adhesive labels as described in the previous edition of DIN 1599 for identifying the grade of steel failed to find any practical applicatio

Similarly it has been decided to dispense with provisions concerning the size of the markings and on relationships between the product dimensions and the kind of mark- ing, since it is not possible to establish any binding rules on this point.

14、r, - form of product, - main dimensions of product. 2.2 The steel grade shall be identifiable from the mark- ing unless agreements of a more far-reaching nature have been reached. Note: Every marking applied means additional expense for the supplier, hence the customer should restrict his requiremen

15、ts regarding features to be identified to those details which are really necessary for his own purposes. 3 Kinds of mark Depending on the method of marking (see Section 4) the marks will consist - either alone or in combination -of figures, letters, geometrical signs (dots, strokes etc.) or coloured

16、 marks. The marks must be readily legible and clearly differentiable. Marking in clear is preferred; if coded marks are used, their significance shall be made known to the purchaser. 4 Methods of marking 4.1 Depending on the form and dimensions of the pro- ducts (see Table l) the marks described in

17、Section 3 can be applied in the following ways: a) rolling (see Section 4.3), b) stamping (see Section 4.41, c) identity plates (see Section 4.5). d) printing (see Section 4.61, e) painting or spraying (see Section 4.71, f) tieon tags (see Section 4.8), g) adhesive labels (see Section 4.9). It shoul

18、d be noted that the methods of marking mentioned in Table 1 for specific products cannot be used indiscrimi- nately for any feature according to Section 2 that has to be identified. 4.2 The marking shall not adversely affect the pro- perties or usefulness of the product (see Section 4.1 O). 4.3 Roll

19、ed-in symbols (i. e. symbols applied by rolling during manufacture) are generally used only for identify- ing the steelmaker, the form of section and possibly the section dimensions of the products stated in Table 1. 4.4 The stamping of symbols is performed mechanically or by hand using steel punche

20、s. 4.5 Pre-manufactured identity plates of metal are attached by welding, cartridge-firing, screwing or bonding. 4.6 Symbols are printed-on by means of stamps or rollers (see also Section 4.10). 4.7 The marks according to Section 3 are painted or sprayed-on either mechanically or manually, frequentl

21、y with the use of stencils. Any colours used for identification purposes (usually of steel grade) should comply with DIN 5381 (see also Section 4.10). 4.8 T i e - o n t a g s shall be of a size not smaller than A7. 4.9 A d h e s i v e I ab e I s must fulfil the conditions of Section 4.10. 4.10 The c

22、olours, tie-on labels or adhesive labels used for applying the markings according to Sections 4.6 to 4.9 must have the following properties: a) adequate resistance to chemical effects caused by the b) adequate resistance to weathering, c) adequate impact resistance, d) good adhesion. Any special req

23、uirements in regard to properties, e. g. ready removability of stamps, coloured markings or adhesive labels must be agreed at the time of ordering. substrate, e. g. rust, 5 Position of marks The position of the marks on the product shall be so chosen that they remain readily visible.
