13、ng facilities 1 This Japanese Industrial Standard specifies the installation methods of heating facilities in general places of fixed heating lines, fixed heating sheets and fixed heating boards of the working voltage not higher than 600 V in the inside or the surface of the work pieces such as road
14、, parking area, building material and pipe line, or under the ground, on the ground surface, in the air or in the water. This Standard does not apply to the heating line when using heating lines as one of the elements of machine or apparatus. General places mean such places that do not include the f
15、ollowing places: Scope Remarks : a) Places in which flammable gas or vapor of inflammable fluid of firing point not higher than 40 “C exist and come to a dangerous concentration or places likely to come to the condition like that. Places in which deflagrating dust, conductive dust, inflammable dust
16、or flam- mable fibre exists and, therefore, electrical equipment is likely to be an ignition source to bring about explosion or fire. Places in which flammable and dangerous materials such as celluloid, match and oils are manufactured or stored. Power magazine, explosives manufacturing or handling p
17、laces to which the Ex- plosives Control Law (1950, Law No. 149) applies. b) c) d) 2 Normative references The standards listed in attached table 1 contain provi- sions which, through reference in this Standard, constitute provisions of this Standard. The most recent editions of the standards (includi
18、ng amendments) shall be applied. 3 Definitions For the purpose of this Standard, the following definitions apply: heating resistor a conductor which generates Joule heat when passing elec- tric current through it heating line a cord to generate heat for heating up. Some of which are equipped with sh

The heating lines used for heating facilities shall comply with 5 Design The design of heating facilities shall be as follows: a) The voltage to ground in
37、the cable way for supplying electricity to the heating lines is not higher than 150 V. However, when equipping other structure than hous- ing with the heating lines, the voltage to ground may be not higher than 300 V. The temperature of heating resistor is not higher than either the maximum al- lowa
38、ble temperature of insulators given in annex table 3 or the maximum allow- able temperature of heating resistor the manufacture expresses, whichever is lower. The temperature due to the heating up by the heating lines is as follows: 1) b) c) Temperature of not more than 80 % of the ignition temperat
39、ure of the ob- ject to be heated (including fluid and its vapour). Not higher than 80 “C in the case where the building materials around the heating lines are inflammable materials such as wood and there are parts which the heat lines touch or are likely to touch. Not higher than 45 “C in the case o
40、f the floor surface equipped with floor heating in the residential part. 2) 3) d) Building materials are prevented from change in colour or deformation caused by the heat of heating lines. The selection of the heating lines according to the places to be equipped is as given in table 1. e) PROTECTED
