2 The well-known standards for cable glands, such as DINVDE 0619 (VDE 0619): 1987-09, DIN 46 319: 1989-12, DIN 46 320-1: 1985-09 and DIN 46 : 1973-01 etc, are only applicable until Approved technical drawingsusing these standards are valid until ) Fields of application for standard EN 50 262: This European standard contains the requirements and tests for the construction and design of metric cable glands. This standardcovers the cable gland as a complete part, but not the parts of cable ) The screw-in thread of cable glands must be constructed according to CHART 1 of EN 60 423. The dimensions of the thread are M6x0,75; M8x1; M10x1; ; ; ; ; ; ; ; and ) The mounting holes must be dimensioned according to CHART ) cable glands must be able to guarantee the retaining power for cables and conduits for the complete sealing section.

3 cable glands with traction relief for cables and conduits mustfree the conduits from the load of tension and twist. The tests are carried out, with in each case the smallest and largest mentioned value of the seal resp. tension relief section of theaccording loads and torque values in CHART tests are performed with test pins reproducing the outer diameters of the cables and conduits. The test pins consist of a metal rod with an elastomere ) cable glands must be impact resistant. A test pin according to the smallest value of the sealing section is fastened to the test probe and then the test is carried out a lowesttemperature according to the energy in accordance with category of CHART C.

4 All specifications, charts and values are excerpts from standard DIN 50 262. Obviously further tests(electric properties, IP-Code etc.), which are necessary to classify and mark cable glands are described in this standard.
