24、uipment for the heating of materials, where the heating of materials is one of the functions of the equipment. NOTE If all or part of the equipment falls within the scope of one or more other part 2 standards of IEC 61010 as well as within the scope of this standard, it will also need to meet the re

25、quirements of those other part 2 standards. In particular, if equipmen is intended to be used for IVD purposes, it will need to meet the requirements of IEC 61010-2-101. 1.1.2 Equipment excluded from scope Addition after item j): aa) equipment for the heating and ventilation of laboratories; bb) ste

26、rilizing equipment; cc) heating and/or cooling equipment which the OPERATOR is intended to enter, and which is large enough for the OPERATOR to remain inside with the door or doors closed. 2 Normative references This clause of Part 1 is applicable, except as follows: Addition: ISO 7010:2011, Graphic

28、010-2-010:2014 IEC 2014 7 4 Tests This clause of Part 1 is applicable except as follows: 4.4.2.11 Heating devices Addition: If a HAZARD could be caused by overfilling or under-filling with a liquid HEAT TRANSFER MEDIUM, the equipment shall be tested when empty, partially filled, or overfilled, which

29、ever is least favourable. In case of doubt, the test shall be carried out in more than one condition. The HEAT TRANSFER MEDIUM used for the test shall be of a type specified for NORMAL USE. 5 Marking and documentation This clause of Part 1 is applicable except as follows: 5.1 Marking Table 1 Symbols

30、 Addition: Number Symbol Publication Description 101 Background colour yellow (optional, not green); symbol and outline black (optional). ISO 7010 W021 Warning; Flammable material 5.1.3 MAINS supply Addition to item c): If, for periods of 1 min or less after switching on, the actual power or current

31、 can be much higher than the marked maximum RATED power or current, the short-term maximum may be marked in brackets after the maximum RATED power or current. 5.1.6 Switches and circuit-breakers Addition: For ovens and similar equipment, there shall be an indication of the “ON” condition on each sid

32、e of the equipment which has a door in it or has any other opening intended for loading material. 5.2 Warning markings Replacement of the first paragraph by the following: Warning markings specified in 5.1.5.2 c), 5.2.101, 6.1.2 b), 6.1.2.101 2), 7.3.2 b) 3), 7.4, 10.1, 9.5 c), and 13.2.2 shall meet

33、 the following requirements: Additional subclause: BS EN 61010-2-010:2014 8 IEC 61010-2-010:2014 IEC 2014 5.2.101 Equipment with high ACCESSIBLE current If the ACCESSIBLE current of the equipment exceeds the limit of 6.3.1 b) or 6.3.2 b) for non-permanently connected equipment, but is within the lim

34、it for PERMANENTLY CONNECTED EQUIPMENT, there shall be a warning marking requiring permanent connection to the supply source. The marking shall be on or beside the cover of the TERMINALS for connection to the supply source, and the warning shall be repeated in the installation instructions. Symbol 1

35、4 of Table 1 is an adequate warning marking, particularly when it may not be known in which country the equipment will be used and, therefore, in which language it would be appropriate to print the warning marking. Conformity is checked by inspection. 5.4.3 Equipment installation Replacement: The do

36、cumentation shall include installation and specific commissioning instructions (examples are listed below) and, if necessary for safety, warnings against HAZARDS which could arise during installation or commissioning of the equipment: a) assembly, location and mounting requirements. If a HAZARD coul

37、d be caused by hot items falling from the equipment, for example when a door is opened, there shall be a warning that the equipment shall not be mounted on a surface of flammable material; b) instructions for protective earthing; c) connections to the supply, including the warning and statement whic

38、h are necessary when permanent connection to the supply source is essential (see 5.2.101), and for equipment in which HAZARDOUS LIVE parts may need to be ACCESSIBLE (see 6.1.2), a statement requiring the fitting of a residual current-operated circuit-breaker; d) for PERMANENTLY CONNECTED EQUIPMENT:

39、1) supply wiring requirements; 2) requirements for any external switch or circuit-breaker (see 6.11.2.1) and external overcurrent protection devices (see 9.6.2), and a recommendation that the switch or circuit-breaker be near the equipment; e) ventilation requirements; f) requirements for special se

40、rvices, for example, air, cooling liquid; g) the maximum sound level produced by equipment which emits sound, if measurement is required by 12.5.1; h) instructions relating to sound level (see 12.5.1); i) any requirement for drying-out (see 5.4.3.101); j) if the heating of materials could lead to li

41、beration of hazardous substances, installation instructions shall warn of any need for an extraction system, additional temperature-limiting devices relating to safe temperatures for the materials, etc. (also see the note to 5.4.1). NOTE An extraction system is a system which removes air from the bu

42、ilding, not a recirculating system. Conformity is checked by inspection. Additional subclause: 5.4.3.101 Drying-out If, after transport or storage in humid conditions, equipment could fail to meet all the safety requirements of this standard, the installation instructions shall specify a period of o

43、peration BS EN 61010-2-010:2014IEC 61010-2-010:2014 IEC 2014 9 to dry out the equipment and restore it to NORMAL CONDITION. The instructions shall include a warning that the equipment cannot be assumed to meet all the safety requirements of this standard during the drying-out process. Conformity is

44、checked by inspection. 5.4.4 Equipment operation Addition at the end of item g): (see 5.4.4.101) Addition after item j): aa) specification of additional protection needed by the OPERATOR when HAZARDOUS LIVE parts are permitted to be ACCESSIBLE (see 6.1.2.101); bb) a warning about any possible HAZARD

45、S of explosion, implosion, or the release of toxic or flammable gases arising from the materials being heated (also see 5.4.4 h); cc) specification of HEAT TRANSFER MEDIA which are suitable for use, for example liquids for use in a heating bath. dd) specific requirements for ventilation. Additional

46、subclause: 5.4.4.101 Cleaning and decontamination The instructions shall include recommendations for cleaning and, where necessary, decontamination, together with the recognized generic names of recommended materials for cleaning and decontamination, and an indication of any materials which could be

47、 likely to be used but which are incompatible with parts of the equipment or with material contained in it. The instructions shall also state that the RESPONSIBLE BODY shall ensure that: a) appropriate decontamination is carried out if hazardous material is spilled onto or into the equipment; b) no

48、decontamination or cleaning agents are used which could cause a HAZARD as a result of a reaction with parts of the equipment or with material contained in it; c) the manufacturer or his agent is consulted if there is any doubt about the compatibility of decontamination or cleaning agents with parts

49、of the equipment or with material contained in it. Manufacturers should be aware of the internationally recognized “Laboratory Biosafety Manual”, published by the World Health Organization in Geneva, which gives information on decontaminants, their use, dilutions, properties and potential applications. There are also national guidelines which cover these areas. Cleaning and decontamination may be necessary as a safeguard when laboratory heating equipment and any accessories are maintained, repaired, or tran
