16、18 This European Standard is divided into two parts Part 1: General requirements which are common to most hand-held electric motor operated tools (for the purpose of this standard referred to simply as tools) which could come within the scope of this standard; Part 2: Requirements for particular typ
17、es of tools which either supplement or modify the requirements given in Part 1 to account for the particular hazards and characteristics of these specific tools. This draft European Standard has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Ass
18、ociation and covers essential requirements of EC Directive 2006/42/EC. See Annex ZZ. Compliance with the clauses of Part 1 together with this Part 2-22 provides one means of conforming with the essential health and safety requirements of the Directive concerned. Warning: Other requirements and other
19、 EC Directives can be applicable to the products falling within the scope of this standard. This European Standard follows the overall requirements of EN ISO 12100-1 and EN ISO 12100-2. This Part 2-22 is to be used in conjunction with EN 60745-1:2009. When this standard states “addition“, “modificat
20、ion“ or “replacement“, the relevant text in Part 1 is to be adapted accordingly. Subclauses and figures which are additional to those in Part 1 are numbered starting from 101; additional annexes are lettered AA, BB, etc. Subclauses, tables and figures which are additional to those in IEC 60745-2-22
21、are prefixed “Z”. Annexes ZA and ZZ have been added by CENELEC. NOTE In this standard, the following print types are used: - Requirements: in roman type; - Test specification: in italic type; - Notes: in smaller roman type.
