ANNEX 3 PROTECTION AGAINST DIRECT CONTACTS OF PARTS UNDER VOLTAGE Extract from the IEC 529 Standard (1989) 1. DEFINITIONS For the purpose of this standard, the following definitions apply: 1.1. Enclosure A part providing protection of equipment against certain external influences and, in any direction, protection against direct contact (IEV 826-03-12). Note : This definition taken from the existing international electrotechnical vocabulary (IEV) needs the following explanations under the scope of this standard: (a) Enclosures provide protection of persons (or livestock) against access to hazardous parts. (b) Barriers, shapes of openings or any other means — whether attached to the enclosure or formed by the enclosed equipment — suitable to prevent or limit the penetration of the specified test probes are considered as a part of the enclosure, except when they can be removed without the use of a key or tool. 1.2. Direct contact Contact of persons (or livestock) with live parts (IEV 826-03-05). Note : This IEV definition is given for information. In this standard ‘Direct contact’ is replaced by ‘Access to hazardous parts’. 1.3. Degree of protection The extent of protection provided by an enclosure against access to hazardous parts, against ingress of solid foreign objects and/or against ingress of water and verified by standardised test methods. 1.4. IP code A coding system to indicate the degrees of protection provided by an enclosure against access to hazardous parts, ingress of solid foreign objects, ingress of water and to give additional information in connection with such protection. 1.5. Hazardous part A part that is hazardous to approach or touch. 1.5.1. Hazardous live part A live part which, under certain conditions of external influences, can give an electric shock (see IEC 536, at present Document 64(CO)196). 1.5.2. Hazardous mechanical part A moving part, other than a smooth rotating shaft, that is hazardous to touch. 1.6. Protection provided by an enclosure against access to hazardous parts. The protection of persons against: (a) contact with hazardous low-voltage live parts; (b) contact with hazardous mechanical parts; (c) approach to hazardous high-voltage live parts below adequate clearance inside an enclosure. Note : This protection may be provided: (a) by means of the enclosure itself; (b) by means of barriers as part of the enclosure or distances inside the enclosure. 1.7. Adequate clearance for protection against access to hazardous parts A distance to prevent contact or approach of an access probe to a hazardous part. 1.8. Access probe A test probe simulating in a conventional manner a part of a person or a tool, or the like, held by a person to verify adequate clearance from hazardous parts. 1.9. Object probe A test probe simulating a solid foreign object to verify the possibility of ingress into an enclosure. 1.10. Opening A gap or aperture in an enclosure which exists or may be formed by the application of a test probe at the specified force. 2. TESTS FOR PROTECTION AGAINST ACCESS TO HAZARDOUS PARTS INDICATED BY THE ADDITIONAL LETTER 2.1. Access probes Access probes to verify the protection of persons against access to hazardous parts are given in table l. 2.2. Test conditions The access probe is pushed against any openings of the enclosure with the force specified in table 1. If it partly or fully penetrates, it is placed in every possible position, but in no case shall the stop face fully penetrate through the opening. Internal barriers are considered part of the enclosure as defined in paragraph 1.1. For tests on low-voltage equipment, a low-voltage supply (of not less than 40 V and not more than 50 V) in series with a suitable lamp should be connected between the probe and the hazardous parts inside the enclosure. Hazardous live parts covered only with varnish or paint, or protected by oxidation or by a similar process, are covered by a metal foil electrically connected to those parts which are normally live in operation. The signal-circuit method should also be applied to the hazardous moving parts of high-voltage equipment. Internal moving parts may be operated slowly, where this is possible. 2.3. Acceptance conditions The protection is satisfactory if adequate clearance is kept between the access probe and hazardous parts. In the case of the test for the additional letter B, the jointed test finger may penetrate to its 80 mm length, but the stop face (Ø 50 mm × 20 mm) shall not pass through the opening. Starting from the straight position, both joints of the test finger shall be successively bent through an angle of up to 90o with respect to the axis of the adjoining section of the finger and shall be placed in every possible position. In case of the tests for the additional letter D, the access probe may penetrate to its full length, but the stop face shall not fully penetrate through the opening. See Annex A for further clarification. Conditions for verification of adequate clearance are identical with those given in paragraph 2.3.1 below. 2.3.1. For low-voltage equipment (rated voltages not exceeding 1 000 V AC and 1 500 V DC): The access probe shall not touch hazardous live parts. If adequate clearance is verified by a signal circuit between the probe and hazardous parts, the lamp shall not light.
