| 9 | 5 General notes on tests 5.1 Unless otherwise specified, the tests are carried out in the order of the clauses, at an ambient temperature between 15 C and 35 C. In case of doubt, the tests are made at an ambient temperature of (20 ± 5) C. For the testing, the specimens int… 5.2 The number of needed test samples are specified in annex B. 5.3 Unless otherwise specified, mini-couplers are tested with their counterparts, complying with this standard. For non-standardized mini-couplers, the counterparts used shall comply with the standard sheets specified by the manufacturer. 5.4 The neutral circuit, if any, is treated as a pole. 5.5 For the tests carried out on one specimen, a mini-coupler is deemed to not comply with the requirements of this standard if there is a failure in one or more of the tests. 5.6 Mini-couplers integrated in or incorporated in an appliance or equipment are tested under the conditions of use of the equipment, the number of specimens then being the same as the number of specimens of equipment required according to the relevan… 6 Marking and instructions 6.1 Mini-couplers shall be marked with: |
| 10 | 6.2 Marking shall be durable and easily legible. 6.3 Instructions for safe use and installation 7 Preconditioning 8 Dimensions |
| 11 | 9 Protection against electric shock 9.1 Mini-couplers shall be so designed that, when they are wired and mounted, as intended, live parts are not accessible. 9.2 External parts of mini-couplers, with the exception of contact pins, assembly screws and the like, shall be of insulating material. 9.3 Insulating linings, barriers and the like, shall have adequate mechanical strength and be reliably fixed. 9.4 Mini-couplers shall be so designed that, when wired as intended, there are no openings giving access to live parts, except the entrance openings for contact pins. 10 Provision for earthing 10.1 Mini-couplers shall be so constructed that, when the plug: 10.2 The earthing circuit of the plug and the connector shall be in one piece or shall be permanently and reliably connected together by riveting, welding or the like. |
| 12 | 10.3 Earthing contacts shall provide adequate contact pressure, and shall not deteriorate in normal use. 11 Terminals and terminations 11.1 Mini-couplers shall be provided with soldered, welded, crimped or equally effective terminations; screwed or snap-on terminals shall not be used. Connections made by crimping a pre-soldered flexible conductor are not permitted, unless the solde… 11.2 Terminations of mini-couplers shall be so located or shielded that loose strands of a conductor in the accessory cannot reduce the creepage distances, clearances or distances through insulation below the values specified in clause 19. 12 Construction 12.1 Pins of plug connectors and inlets shall have adequate mechanical strength. 12.2 Contact pins and tubes of mini-couplers shall not be removable without dismantling the connecting device. 12.3 Contact tubes shall be floating and have sufficient resiliency. 12.4 Mini-couplers shall be so constructed that full engagement of their parts is not prevented by any projection from their engagement faces. 12.5 Mini-couplers shall be non-rewirable and so constructed that: |
| 13 | 12.6 Interconnection cord sets shall be protected by a flexible conduit. 12.7 Internal mini-couplers shall be provided with retaining means. 12.8 External inlets and connectors shall be so designed as to allow easy insertion and withdrawal. 12.9 Outlets in mini-couplers for tapping shall be provided with a covering lid, which however, need not be constructively fixed to the outlet. 12.10 Contact pins of mini-couplers shall be locked against rotation. |
| 14 | 13 Protection against ingress of solid foreign bodies and harmful ingress of water and humidity 13.1 The enclosure of a mini-coupler in engagement shall provide a degree of protection not less than IP44. 13.2 Mini-couplers shall be proof against humid conditions which may occur in normal use. |
| 15 | 14 Insulation resistance and electric strength 14.1 The insulation resistance and the electric strength of mini-couplers shall be adequate. 14.2 The insulation resistance is measured with a d.c. voltage of approximately 500 V applied, the measurement being made individually on each inlet and connector 1 min after application of the voltage. 14.3 A voltage of (2 000 ± 60) V of substantially sine-wave form, having a frequency of 50 Hz or 60Hz, is applied for (60 + 5/-0) s between the parts indicated in 14.2. 15 Temperature rise |
