| 1 | In this revision the life of the heating element of alloys of Nickel-chromium, nickel-iron-chromium, iron-chromium-aluminium alloys, etc, under the prescribed conditions of the test shall be determined at specified temperatures, namely, 1120 oC, 1205 oC and 1230 oC. The selection of the particular alloy material would be made by the user on the basis of indigenous availability, cost and reliability for continued service as per IS 12045. 7 grades of alloys as per IS 12045 have been added along with their test temperatures. Test specimen dimensions have been incorporated for different type of alloys. This standard also covers the testing of specimens having shape other than wires. | |
| 2 | Nickel-chromium, nickel-iron-chromium, iron-chromium-aluminium alloys, etc, have - high resistance to oxidation at elevated temperatures and are widely used for heating elements. The heating elements made of these alloys are suitable for heating devices, such as toasters, percolators, iron machines, heater pads and for electrical applications, namely, high-resistance rheostats and radio and moving-picture equipment, potentiometers, thermocouples and resistors. Method for carrying out the accelerated life test for these heating elements is covered in this standard. For accuracy in test results some precautions are required to be observed while carrying out the test. Such precautions are described in Appendix A of this standard | |
