39、f connectors shall still function correctly. Where the gate locking feature does not encircle the connector body, e.g. Figure 2b) and Figure 3, the gate- locking feature shall withstand a force of (1 0,02) kN without separating from the latch by more than 1 mm. 4.4.2 Gate side When tested in accorda

40、nce with 5.4.2, connectors with a gate locking feature that does not encircle the connector body, e.g. Figure 2b) and Figure 3, shall withstand a force of (1,5 0,03) kN without any partial fracture. After this test the gate-locking feature shall still function correctly. EN 362:2004 (E) 9 4.5 Corros

41、ion resistance When tested in accordance with 5.5, connector gates shall still function in accordance with 4.1.4. Evidence of corrosion of the base metal is not acceptable. The presence of tarnishing and white scaling is acceptable. NOTE Conformity to this requirement does not imply suitability for

42、use in a marine environment. 4.6 Marking and information 4.6.1 Marking of connectors shall be in accordance with Clause 6. 4.6.2 Information shall be supplied with connectors in accordance with Clause 7. 5 Test methods 5.1 Examination of design 5.1.1 General One sample may be used for these tests. C

43、heck that the connectors, in accordance with the definitions in Clause 3, meet the requirements of 4.1.1 to 4.1.7 by visual examination and simple check measurements. 5.1.2 Verification of the gate opening Verify the gate opening a by using a calibrated rod which has a diameter corresponding to the

44、gate opening specified in the information supplied by the manufacturer, see Figure 5. Pass the rod through the gate opening and check that it allows the correct closure and locking of the gate and free movement of the rod within the connector. 5.2 Static strength test 5.2.1 Apparatus The static stre

45、ngth test apparatus is a conventional tensile testing machine. The force measuring apparatus for static testing shall conform to EN 364:1992, 4.1.1.The rate of loading shall lie within the range of 50 mm/min to 200 mm/min if the connector contains a textile element subject to stress during the test;

The static strength tests can be performed outside the conditioning room, but the temperature shall be (23 5) C and the tests shall begin within 5 min of removal from conditioning. b) Test samples without a textile element may be tested without conditioning. c) Each test shall be carried out on a

48、 new sample. EN 362:2004 (E) 10 5.2.3 Method 5.2.3.1 Major axis testing Mount the connector in the tensile testing machine and apply the load by means of two bars with a radius of (6 0,1) mm, which are arranged to be perpendicular to the major axis. It is important that the connector is free to loca

49、te itself on the bars at the start of the test and as the load is applied. The bars shall be well coated with molybdenum based grease where they come into contact with a metal part of the test sample. If the connector is tested in a horizontal axis test machine, the connector shall be positioned in a vertical plane with the gate being the lower of the two major axis sides. If the connector is tested in a vertical axis test machine, apply a small force to the connector
