When this standard states “addition“, “modification“ or “replacement“, the relevant text in Part 1 is to be adapted accordingly. NOTE 1 When “Part 1” is mentioned in this standard, it refers to EN 60745-1. Th

16、is part 2 supplements or modifies the corresponding clauses in EN 60745-1, so as to convert that publication into the EN standard: Safety requirements for die grinders and small rotary tools. When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies as far as is r

17、easonable. When this standard states “addition”, “modification” or “replacement”, the relevant text in Part 1 is to be adapted accordingly. NOTE 2 The following numbering system is used: subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1; unless note

18、s are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including those in a replaced clause or subclause; additional annexes are lettered AA, BB, etc. NOTE 3 In this standard, the following print types are used: requirements: in roman type; test specifications: in

19、italic type; notes: in small roman type. Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective, the adjective and the associated noun are also in bold. Clauses, subclauses, notes, tables, figures and annexes which are additional to those in IEC 607
