The hot pipe shall be linear to within ± 1 mm in the measuring zone at ambient temperature. The hot pipe shall be capable of being controlled to within ± 2 % of a predetermined temperature ± 10 °C whichever is smaller over the central 60 % of the total pipe length. The hot pipe shall be capable of being heated at 50 °C/h and/or 300 °C/h. 5.2 End insulation, with a gap as small as possible between end insulation and guard piece of the test specimen (e.g. ≤ 3 mm) which will permit free movement during the test of the test specimen. 5.3 Temperature sensors, (e.g. thermocouples) capable of recording the hot surface temperature of the test pipe to the nearest ± 1 % in centigrade but not less than ± 1 °C, which are placed within grooves on the hot pipe. 5.4 Flexible metal foil, 3 pieces, (e.g. brass) capable of exerting a uniform pressure of 500 Pa on the upper surface of the test specimen along its testing length of (500 ± 5) mm and the two end guards, length (250 ± 5) mm.
The pressure shall be calculated using the area: e.g. the test length of 500 mm times the diameter of the hot pipe. 5.5 Device, e.g. electromechanical for measuring the thickness of the test specimen during the test to the nearest 0,1 mm. When determining the thickness of the test specimen, the thermal movement of the apparatus (e.g. quartz rod) shall be taken into account up to the maximum service temperature. SIST EN 14707:2013
