In keeping with current practice in standards published by the International Organization for Standard
2、ization (ISSO), a comma has been used throughout as the decimal marker. 1 Scope and field of application This standard specifies technical delivery conditions for copper and nickel resistance alloys which, due to their elec- trical resistance and temperature characteristics, are suit- able for the m
3、anufacture of resistors of all kinds as well as heating conductors. This standard does not cover materials for resistance ther- mometers (cf. DIN 43 760). thermocouples (cf. DIN 43 710) or compensating cables (cf. DIN 43 713). 2 Designation The standard designation shall include the name of the mate
4、rial (alloy), the DIN number (DIN 17 471), and the ma- terial designation or number (cf. table 1). Example: Designation of a resistance alloy complying with this standard, made of a material identified by material designation CuNi2 (material number 2.0802): Alloy DIN 17471 - CuNi2 or Alloy DIN 17471
5、 - 2.0802 3 Order details The material, the product form and the as delivered condi- tion shall be specified by the purchaser at the time of order- ing. The manufacturing process shall be at the manufactur- ers discretion. The intended use and any subsequent treatment of the material may be specifie
6、d at the time of ordering. The material designations or numbers specified in table 1 shall be used for ordering purposes. 4 Chemical composition Table 1 only specifies mean values of the content of ele- ments, since the resistivity is the most relevant parameter of the alloys covered here. 5 Propert
7、ies 5.1 Physical properties Values of the resistivity and the coefficient of linear thermal expansion are given in table 2 for materials in the softened condition. Note that the resistivity values at a temperature of 100 OC and higher are guideline values only. Table 3 gives guideline values for oth
8、er physical properties. 5.2 Mechanical properties Table 4 specifies mechanical properties of alloys in the sof- tened condition, at 2OOC. The three nickel alloys covered here are normally supplied as continuously annealed wire, in diameters of less than 1 mm. It should be noted that their tensile st
9、rength is much higher than the values specified. 5.3 Corrosion resistance Information on the corrosion resistance of resistance alloy elements is given in table 5. 5.4 Service temperature Table 6 specifies guideline values for maximum service tem- perature. 5.5 Jointing methods Due to the variety of
10、 applications and materials, no general requirements can be specified for joints or jointing methods. 6 Product forms and as delivered condition Unless otherwise specified, resistance alloys shall be sup- plied in the softened condition, in the form of strip or of bare or covered round or flat wire.
11、 The condition in which the products are to be delivered (e.g. on spools in compliance with DIN 46 399 Part 2 or coiled) shall be specified at the time of ordering. 7 Testing 7.1 Tensile strength Tensile testing shall be carried out as described in DIN 50 114. DIN 50 145 or DIN 51 210 Parts 1 and 2.
12、 7.2 Resistivity Resistivity testing shall normally be carried out at the manu- facturers works, using a routine method. In cases of dis- pute, the reference method described in IEC 468 shall be used, unless otherwise specified. Continued on pages 2 to 6 uth Verlag GmbH, Berlin, has the exclusive ri
