For tools marked with one or more rated voltages, the test is made at each of the rated voltages. For tools marked with one or more rated voltage ranges, the test is made at both the upper and lower limits of the ranges. For tools with multiple gear box settings, the test is made at each specified gear box setting in accordance with 8. 14.2 b). The highest value of input or current is applicable.
Tappers are operated intermittently for 30 cycles or until thermal equilibrium is reached,whichever is achieved first, each cycle comprising a period of continuous operation of 30 s and a rest period of 90 s with the tool switched off, the tool being loaded during the periods of operation by means of a brake adjusted so as to attain rated input or rated current. The temperature rises are measured at the end of the last “on” period.
Threaders are operated for 30 s at load followed by 30 s no load and then switched off for a rest period of 60 s. This cycle is continued until thermal equilibrium is reached, or for 30 cycles, whichever is achieved first. The tool is loaded during the periods of operation by means of a brake adjusted to attain the torque specified in Table 101. The brake load may be ramped up to the specified torque over a period of time not to exceed 5 s. This ramp up time is added to the 30 s cycle at load. The temperature rises are measured at the end of the last load period.
The tool is set with the largest die head in accordance with 8.1 on to a pipe as specified in 8.1. The point of contact with the support device and tool is determined. The support device is mounted in accordance with 8.14.2 a) so there is an 8 mm minimum clearance between the device and the point of contact. See Figure 102.AS NZS 62841.2.9 pdf free download.
