    Abstract - (Show below) - (Hide below)

    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 operating at normal ambient temperatures.NOTEIn cases of substantially higher or lower working temperature, it is advisable to seek the manufacturer’s advice.
