This standard covers complete cable glands as supplied by the manufacturer or the supplier responsible for

35、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 should then be taken of other or additional requir

36、ements necessary for the enclosure to be installed in such conditions, for example as specified in the IEC 60079 series. 2 Normative references 3 Terms and definitions For the purposes of this document, the following definitions apply. 3.1 cable gland a device designed to permit the entry of a cable

37、, flexible cable or insulated conductor into an enclosure, and which provides sealing and retention. It may also provide other functions such as earthing, bonding, insulation, cable guarding, strain relief or a combination of these BS EN 62444:2013Text deletedSee Annex ZA.3.2 entry thread the thread

44、ions for tests 5.1 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 dur

45、ing the tests. NOTE 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 sha

46、ll be pre-conditioned 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 se

47、aling systems of metallic 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

48、 of a series of cable 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 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
