Defines the calculation and design of cold and hot coiled helical extension springs made from round wire and bar loaded in the direction of the spring axis and operating at normal ambient temperatures.

This European Standard specifies the calculation and design of cold and hot coiled helical extension springs made from round wire and bar with values according to Table 1, loaded in the direction of the spring axis and op erating at normal ambient temperatures. Table 1 Characteristic Cold coiled extension spring Hot coiled extension spring Wire or bar diameter d ≤ 20 mm d ≥10 mm Number of active coils n ≥ 3 n ≥ 3 Spring index 4 ≤ w ≤ 20 4 ≤ w ≤ 12 NOTE In cases of substantially higher or lower working temperature, it is advisable to seek the manufacturer’s advice.
