9、to two partsPart 1 General requirements whi ch are common to most hand -held electric motor -operated tools(for the purpose of this standard referred to simply as tools)Part 2 Requirements for particular types of tools which either supplement or modify the requirements given in Part 1 to account fo
10、r the particular hazards and characteristics of these sp ecific tools.This European Standard has been prepared under a mandate given to CEN/CENELEC by the European Commission and the European Free Trade Association and supports the essential health and saf ety requirements of the Machinery Directive
11、.Compliance with the relevant clauses of Part 1 together with this Part 2 provides one means of conforming with the specified essential health and safety requirements of the Directive.For noise and vibration, th is standard covers the requirements for their measurement, the provision of information
12、arising from t hese measurements and the provisions of information 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 the art.CEN/TC 2
13、55 has produced standards for non electric tackers (EN 792 -13).Warning: Other requirements arising from other EC Directiv es can be applicable to the products falling within the scope of this standard.This standard follows the overall requirements of EN 292 -1 and EN 292 -2.Subclauses, tables and f

The referenc

The centre point is located on the driving axis at half of the height of the tacker.NOTE Because a tacker is of small size the centre point of a tacker is used instead of the surface.The measure
