The text of the draft was submitted to the Unique Acceptance Procedure and was approved by CENELEC as EN 50286 on 1998-08-01. The following dates were fixed: latest date by whic

19、ments set out by CLC/TC 78 and with the non- electrical requirements set out by CEN/TC 162. This insulating clothing is recognized as a PPE according to EEC Directive (89/686/EEC). Electrical insulating protective clothing was developed primarily for use by workers for work on low-voltage overhead l

20、ines. For the moment, there is no withstand test applicable to products where the principle risk is of unintentional contact with live parts, and such a test is not included in the present standard. However, despite this lack, it is considered that a satisfactory level of electrical protection is pr

21、ovided by compliance with this standard for both the proof tests and the periodic electrical inspections. For the moment, no test is available in relation to the risk of workers exposure to an electrical arc generated by low-voltage installations. This task is presently under study by WG7. Page 4 EN

22、 50286:1999 BSI 6 May 2005 1 Scope This standard is applicable to electrical insulating protective clothing used by skilled persons when they are working on or near live parts of low-voltage installations at nominal voltages up to 500 V a.c. or 750 V d.c. The purpose of this clothing when used in co

23、njunction with other PPE, such as boots and gloves etc., is to prevent dangerous current from passing through persons when there is a risk of unintentional contact with several live parts located in and around the working area. Where the risk of unintentional contact with live parts is restricted, e

24、.g. with live parts in front of the worker, the wearing of this clothing is not essential. NOTE Some restrictions on the use of this clothing may exist in areas with hot climatic conditions, for example. 2 Normative references This European Standard incorporates by dated or undated reference, provis

35、mod. 3.3.5 Proof test voltage A specified voltage that is applied to an article of clothing for the time defined under specified conditions to assure that the electrical strength of the insulation is above a specified value. 4 Requirements 4.1 Non-electrical requirements 4.1.1 Weights, dimensions an

36、d design No metal parts shall be on the outside of the protective clothing. Touch and close fastener shall be used. The protective clothing shall consist of a jacket with hood and trousers or an overall with a hood. The weight of protective clothing shall comply with values given in Table 1. The man

37、ufacturing dimensions shall comply with those given in Table I, which is based on EN 340. Other dimensions may be chosen in a similar manner. All seams, except hem-seams, shall be safe in the electrical environments. Page 6 EN 50286:1999 BSI 6 May 2005 The number of pockets in the protective clothin

38、g shall be limited to two. The protective suit shall have one pocket for the jacket and one for the trousers. The protective overall shall have two pockets located in similar positions. One pocket shall be placed at the chest level to the jacket or the overall. One pocket shall be placed laterally t

39、o the thigh to the trousers. The pockets shall be equipped with flaps that shall have close and touch fasteners. The hood shall be securely fastened to the jacket or overall. The method of fastening shall ensure that: the hood cannot become separated or detached, either in part or completely, from t

40、he jacket or overall, when the clothing is in use; the integrity of the electrical insulation of the clothing is maintained both across and along the length of the means of fastening, when the clothing is in use. Examples of methods of fastening which meet these requirements are: sewn seams which me

41、et the requirements in accordance with 4.2; zip-fasteners provided inside and outside with insulating flaps and touch and close fasteners that completely cover all parts of the zip-fastener. The front edge of the hood shall be designed all around in such a way that a cord made from insulating materi

42、al can be taken in. The cord shall be taken in the hood, but it shall not be fixed. The hood shall be designed so that a protective helmet with face shield can be worn inside the hood. The cord of the hood shall allow the hood to fit closely to the protective helmet. Any zip-fastener necessary to cl

43、ose the jacket, the trousers or the overall shall be made from insulating material. However, if metal parts are used for the slider or for the terminal pieces of the zip-fastener, they shall be covered with insulating material. The length of the zip-fastener shall correspond to the design of the jac

44、ket. The length shall be designed in such a way that the zip-fastener begins (10 2) cm above the hem seam and ends (3 1) cm below the edge of the hood. The zip-fastener shall be covered by a flap that begins at the hem seam and ends at the hood seam. The flap shall be equipped with a touch and close

45、 fastener, which covers at least the whole length of the zip-fastener. For the overall, the length of the zip-fastener and the design of the flap shall be chosen in a similar manner. The cuff of the sleeves shall be adjustable by means of a tab with a touch and close fastener. The bottoms of the tro

46、users or overall legs shall be wide enough to be worn over footwear. The trousers shall be equipped with a fly that is closed over its length by a zip-fastener. The fly shall be covered by a flap that shall have a touch and close fastener over the whole length. The trousers shall be equipped with br

47、aces that shall be securely connected to the trousers and shall be adjustable or elasticated. The elasticity may be achieved by a complete elastic brace or a piece of elastic in the brace. The colour shall be bright. NOTE The protective clothing should have a unique colour. A red colour is recommend

48、ed. This colour may differ from colour code marking.
