This standard covers complete cable glands as supplied by the
30、manufacturer or the supplier responsible for placing the product on the market. This standard does not cover cable glands for mineral insulated cables. This standard covers cable glands with IEC 60423 metric entry threads. NOTE Certain cable glands may also be used “in Hazardous Areas.” Regard shoul

37、with more than one orifice, each orifice being suitable for the passage of a separate cable 4 General requirements Cable glands shall be designed to provide in normal use all the functions declared by the manufacturer or supplier. BS EN 62444:2013 8 62444 IEC:2010 5 General conditions for tests 5.1
38、Tests according to this standard are type tests. 5.2 Unless otherwise specified, the tests shall be carried out on new cable glands assembled and mounted in accordance with the manufacturers or suppliers instructions, as declared in 7.3. There shall be no adjustment between or during the tests. NOTE
39、 Remounting of the sample between tests is not considered to be adjustment. 5.3 Unless otherwise specified, the tests shall be carried out at an ambient temperature of (20 5) C. 5.4 Non-metallic and composite cable glands as well as the sealing systems of metallic cable glands shall be pre-condition
40、ed in an oven at (70 2) C and maintained for (168 4) h. If the maximum temperature declared by the manufacturer is greater than 65 C, then the test temperature shall be the declared temperature +5 C. 5.5 Prior to the tests, non-metallic and composite cable glands as well as the sealing systems of me
41、tallic cable glands shall be conditioned at a temperature of (20 5) C and a relative humidity between 40 % and 60 % for a minimum of 24 h or longer as specified by the manufacturer. 5.6 Unless otherwise specified, three samples shall be subjected to the relevant tests. In the case of a series of cab
42、le glands, three samples of the largest and smallest and one sample of all other sizes of the same series shall be subjected to the relevant tests. In the case of a cable gland utilising alternative sealing arrangements, each sealing arrangement as specified by the manufacturer or supplier shall be
43、considered as a sample. If a sample does not satisfy a test due to an assembly or manufacturing fault, that test and any preceding one which may have influenced the results of the test shall be repeated on 3 new samples of the size that failed. The tests which follow shall be made in the required se
44、quence. All new samples shall fulfil the requirements. 5.7 Unless otherwise specified test mandrels shall consist of bars having a hardness of 65 Shore D 15 points in accordance with ISO 868 and a surface roughness less than or equal to 7 m Rain accordance with ISO 4287. The test mandrel shall have
45、a tolerance of 0,2 mm for test mandrels up to and including 16 mm in diameter and 0,3 mm for test mandrels larger than 16 mm in diameter. The shape shall be circular or a profile simulating the outer dimension of the cables as declared by the manufacturer or supplier. 5.8 Clearance holes for test pu
46、rposes shall have the values as given in Table 1, unless otherwise specified by the manufacturer or supplier. NOTE Annex B shows test sequences which shall be used for guidance only.
