14、2012-01-02 latest date by which the national standards conflicting with the amendment have to be withdrawn (dow) 2014-01-02 This European Standard is divided into two parts: Part 1 General requirements, which are common to most transportable motor, operated tools (for the purpose of this European St

15、andard referred to simply as tools) which could come within the scope of this European Standard. Part 2 Requirements for particular types of tool which either supplement or modify the requirements given in Part 1 to account for the particular hazards and characteristics of these specific tools. This

16、 European Standard has been prepared under Mandate M/396 given to CENELEC by the European Commission and the European Free Trade Association and covers essential requirements of EU Directive 2006/42/EC. See Annex ZZ. Compliance with the relevant clauses of Part 1 together with a relevant Part 2 of t

17、his European Standard provides one means of confirming with the specified essential requirements of the Directive. For noise and vibration this European Standard covers the requirements for their measurement, the provisions of information arising from these measurements and the provision of informat

18、ion about the Personal Protective Equipment required. Specific requirements for the reduction of the risk arising from noise and vibration through the design of the tool are not given as this reflects the current state of art. Warning: Other requirements arising from other European Directives can be

19、 applicable to the products falling within the scope of this European Standard. CEN have prepared standards for industrial machines, which may extend transportable machines. Although CEN and CENELEC have where appropriate used common solutions to provide uniform levels of protection, person using th

20、is European Standard should check the scope of both this and CEN standards to ensure that a correct standard is used. This Part 2-12 is to be used in conjunction with EN 61029-1:2009. This Part 2-12 supplements or modifies the corresponding clauses of EN 61029-1, so as to convert it into the Europea

21、n Standard: “Particular requirements for threading machines”. BS EN 61029-2-12:2011- 3 - EN 61029-2-12:2011 Where a particular subclause of Part 1 is not mentioned in this Part 2-12, that subclause applies as far as reasonable. Where this Part 2-12 states “addition“ “modification“ or “replacement“,

22、the relevant text of Part 1 is to be adapted accordingly. NOTE In this European Standard the following print types are used: - requirements proper: in roman type; - test specifications: in italic type; - explanatory matter: in smaller roman type.

The diameter shall refer to a unified ISO thread to be cut on a pipe of steel having a tensile strength of 390 N/mm2, unless otherwise indic

32、ated on the tool. 7.13 Replacement: An instruction manual and safety instructions shall be provided with the tool and packaged in such a way that is noticed by the user when the tool is removed from the packaging. The safety instructions may be separate from the instruction manual. An explanation of

33、 the symbols required by this standard shall be provided in either the instruction manual or the safety instructions. They shall be written in the official language(s) of the country in which the tool is sold. They shall be legible and contrast with the background. The words Original instructions sh

34、all appear on the language version(s) verified by the manufacturer or his authorised representative. Where no Original instructions exist in the official language(s) of the country where the tool is to be used, a translation into that/those language(s) shall be provided by the manufacturer or his au

35、thorised representative or by the person bringing the tool into the language area in question. The translations shall bear the words Translation of the original instructions and they shall be accompanied by a copy of the Original instructions. 7.13.101 Safety warnings The safety warnings specified i

36、n 7.13.101.1 and 7.13.101.2, if in English, shall be verbatim and in the exact order as given and in any other official language to be equivalent. Format of all safety instructions must differentiate, by font highlighting or similar means, the context of the clauses as illustrated below. All notes i

37、n the safety warnings are not to be printed, they are information for the designer of the manual. 7.13.101.1 General power tool safety warnings WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious inj

38、ury. Save all warnings and instructions for future reference. 1) Work area safety a) Keep work area clean and well lit. Cluttered or dark areas invite accidents. b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sp

39、arks which may ignite the dust or fumes. c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control. BS EN 61029-2-12:2011- 7 - EN 61029-2-12:2011 2) Electrical safety a) Power tool plugs must match the outlet. Never modify the plug in any way. Do n

40、ot use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock. b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your bo

41、dy is earthed or grounded. c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or movi

42、ng parts. Damaged or entangled cords increase the risk of electric shock. e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. f) If operating a power tool in a damp location is unavoidable

43、 or there is the likelihood of cutting into the cord, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock. NOTE The term “residual current device (RCD)” may be replaced by the term “ground fault circuit interrupter (GFCI)” or “earth leakage circuit

44、breaker (ELCB)”. 3) Personal safety a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious

45、personal injury. b) Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. c) Prevent unintentional starting. Ensure the switch is in

46、the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents. d) Remove any adjusting key or wrench before turning the power tool on. A

47、wrench or a key left attached to a rotating part of the power tool may result in personal injury. e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. f) Dress properly. Do not wear loose clothing or jewellery. Kee

48、p your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts. g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-relat

49、ed hazards. 4) Power tool use and care a) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed. b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired. c) Disconnect the plug from the power source and/or
