The materials of the hardware (nuts and lock-washers) shall be non-magnetic corrosion resistance steel. 5 Description 5.1 M
30、aterials/Features The relay base assembly consists of: socket body: the material shall be a thermoplast, non-flammable, according to EN 2349-100 and this specification; sealing rubber: the material shall be silicon rubber, non-flammable, according to EN 2349-100 and this specification. The sealing r
31、ubber shall seal wires with external diameters as shown in the product standard; crimp contacts: in accordance with EN 3155-017. The crimp contacts shall be selected to accommodate cables as defined in 4.3. The finish of the crimp contacts shall be: gold-plated Thickness: 1,27 m min. 5.2 Interface s
32、eal The relay and base interface shall be sealed by a silicon rubber. The rubber prevents any environmental influence such as fluids between: relay and base; base and wiring. BS EN 2593-001:2014EN 2593-001:2014 (E) 7 The rubber shall provide an additional electrical isolation between relay terminals
33、 and housing. The hardness of the rubber shall not cause any damage or mechanical deformations when tightening the relay on its base. The silicon rubber shall be a part of the plug-in relays in accordance with EN 2548-001. 5.3 Polarizing holes 5.3.1 Two-pole bases The relay bases shall be provided w
34、ith polarizing holes to accept the polarizing pins used on the two-pole relays only. The shape of the polarizing holes shall accept the polarizing pins used on the 28 V d.c. and 115 V a.c. coil relays of EN 2548-001. The purpose of the polarizing pins and holes is to prevent installation of 28 V d.c
35、. or 115 V a.c. coil relays into the non-mating relay base. The polarizing pin shall ensure the correct installation of the relay to its base. 5.3.2 Four-pole bases The keying of the four-pole d.c. and a.c. coil relay bases shall be provided by different coil terminal positions. They shall also ensu
36、re installation of relay on its base in one position only. On a four-pole version this fool proofing shall be ensured by the contact pins position. 6 Definition drawings and mass For the dimensions and mechanical characteristics, reference is made to the product standards. 7 Qualification tests The
37、relay bases shall meet the applicable requirements of EN 2349-100 as shown in Table 1. The qualification test shall be performed together with the mating relay.

44、equired quality level. The documentation shall be maintained by the manufacturer for a period of five years minimum. 8.2 Qualification procedure 8.2.1 General The test samples shall be series production units, selected by random from a batch. All test results shall be recorded. 8.2.2 Test sequence T
45、he qualification test samples shall be in accordance with Table 5, considering the requirements as per Table 1. In case one sample fails to meet the requirements, it shall be replaced by a new test sample and the whole test sequence related to the failed unit to be repeated. In case two or more samp
