The UK participation in its prepa

2、ration was entrusted to Technical Committee MCE/10, Belts L is the dry distance measured in a straight line between the electrodes, see 5.2 and Figure 1; W is the width of the electrode (or belt if narrower than the electrodes). NOTE 1 The resistance value relates to the initial resistance of new be

3、lts. NOTE 2 The dimensions L and W are expressed in the same units. 3.3 Minimum value of electrical resistance Belts with values of resistance below 1 x 10 4 should be classified as conductive. In such cases, it is the end users responsibility to ensure that values of resistance below this recommend

4、ed value do not present a hazard in the environment where the belts are being used. Marking on belts needs to be indelible and clearly visible, but of the smallest practicable area to avoid introducing unnecessary insulation materials. The position of the marking should be such that it does not mate

5、rially affect the electrical resistance of the discharge path across the belt surface. 4 Selection and preparation of belts for test 4.1 Laboratory test Belts shall be tested no less than 8 h after production. Prior to test, the following conditions shall be met. a) The belt shall be maintained in a

6、n unstrained state, for a period of not less than 2 h in a standard atmosphere 23/50, in accordance with ISO 23529 at a temperature of (23 2) C and (50 5) % relative humidity. b) Belt surfaces shall not be buffed, abraded or cleaned with organic materials which attack or swell the materials to be te

7、sted. 4.2 Production test Belts can be tested after production with belt temperature between 15 C and 30 C. Prior to test the following conditions shall be met: Belt surfaces shall not be buffed, abraded or cleaned with organic materials which attack or swell the materials to be tested. NOTE Where l

8、aboratory/production control testing is carried out on numerous belt widths it can be impractical to have electrodes for each belt width. In these cases it is acceptable to test belts and calculate maximum resistance values based on belt width while using narrower or wider electrodes.2 ISO 2015 All

9、rights reservedBS ISO 9563:2015ISO 9563:2015(E) 5 Test method 5.1 Apparatus insulation tester The test should be made preferably with an insulation tester (ohm-meter) having a nominal open circuit voltage of 500 V d.c. or with any suitable instrument known to give comparable results. The instrument

10、should be sufficiently accurate to determine the resistance to within 10 % and not dissipate more than 3 W in the specimen. NOTE Insulation testers have an inherent characteristic of limited power output; therefore the voltage which they apply to the test piece is less than their open circuit voltag

11、e at low resistance values of the test piece. This is a useful characteristic as it reduces the risk of shock and of overheating the test piece. Insulation testers of this type may be manually or power-driven generators or battery- or mains-operated multi-range instruments with similar electrical ch

12、aracteristics. 5.2 Electrodes and contacts for laboratory and production tests Electrodes shall be used that have a profile which fits that of the belt being tested. Electrodes shall be made of a suitable conducting material. Care shall be taken to avoid use of materials which may form a non-conduct

13、ing layer under exposure to the environment (e.g. oxidation). Two electrodes shall be applied to the belt so that they each cover the top surface of 3 adjacent teeth and the sides and bottom of two grooves. The distance between the two electrodes shall span seven grooves and six teeth. Electrodes sh

14、all have a minimum width of 20 mm (Figure 1). The electrodes may be mounted on an insulating handle to allow ease of use and to ensure that the correct distance is used for each test. This necessitates a dedicated set of suitable electrodes for each pitch and tooth profile. 5.3 Test procedures 5.3.1

15、 Laboratory test A test belt of known width shall be placed teeth uppermost on an insulated surface. The electrodes shall be applied to the toothed surface as per 5.2 and a pressure between 10 kPa to 40 kPa applied. A conductive solution/gel/powder may be applied to the belt surface to ensure optimu

16、m contact between electrode and belt (see Annex A). Care should be taken to ensure that the conductive medium is only applied in the area of contact for the electrodes. 5.3.2 Production test A test belt of known width shall be placed teeth uppermost on an insulated surface. The electrodes shall be a

17、pplied to the toothed surface as per 5.2. The pressure applied shall be constant with each type of belt used and such that it does not allow deformation or damage to the belt surface. This procedure is intended for general production testing so hand pressure is sufficient. 5.3.3 Test timing Measure

18、the electrical resistance between the contacts using the insulation tester (see 5.1). Take the reading 5 s 1 s after the application of the meter voltage. 5.3.4 Interpretation of results Verify that the value measured in 5.3.1 and 5.3.2 is not greater than the resistance value calculated in 3.2.
