1.1 Method(s) of mounting (to be inserted) (See IEC 60738-1:2006, 7.30). 1.2 Dimensions (All dimensions are in millimetres or inches and millimetres; it shall be stated which dimensions are suitable for gauging). Dimensioned drawing(s) shall be given in the detail specification. If necessary, the dimensions may be listed in tabular form with reference to styles or codes. 1.3 Coating The detail specification shall state a) whether the thermistor is insulated or non-insulated, b) the material, c) the colour, if applicable. 1.4 Terminations The detail specification shall state whether the terminations are suitable for soldering. If they are not, suitable methods of connection shall be stated for example: welding, clamping or crimping. 1.5 Flammability The detail specification shall state whether the thermistor is actively or passively flammable if applicable. The test method shall be given in the test schedule. 1.6 Resistance to solvents The detail specification shall state whether the coating and the marking of the thermistor are solvent resistant if applicable. The test methods shall be given in the test schedule. 1.7 Packaging The detail specification shall give the following information (if required): a) whether bulk packed or taped and if taped, drawing or references; b) the dimensions of the immediate packaging and the number of thermistors packed; c) the dimensions of the outer package and the number of immediate packages; d) methods of disposal of the packaging material. 1.8 Electrical data/Ratings and characteristics The detail specification shall give units and tolerances or limiting values for the following parameters. If necessary, electrical data may be listed in tabular form, with reference to styles and codes. Upper/Lower category temperatures (UCT/LCT); Operating temperature range at maximum voltage; Maximum voltage (Uˇmax^.); Zero-power resistance (RˇT^); Isolation voltage (insulated thermistors only); Insulation resistance (insulated thermistors only); Tripping current (Iˇt^); Maximum non-tripping current (Iˇmax. nt^); Residual current at Uˇmax^. (Iˇres^); Maximum overload current (Iˇmo^); Switching temperature (Tˇb^) for information only.
