scope:

This international Standard applies to transportable diamond saws with water supply and with a saw blade diameter of not more than 250 mm.

NOTES

1 For tools having saw blades with a diameter of more than 250 mm, additional requirements are under consideration.

2 This standard does not cover bench.type diamond saws.

3 This standard does not cover diamond saws not guided by a track.

a) easily moved by one person, simple devices to facilitate transportation may be incorporated, e.g. handles, wheels and the like;

b) used in a safe stationary position with or without fixing, e.g. fast clamping devices, bolting and the like;

c) used under the control of an operator;

d) not intended for continuous production or production line use;

e) intended to be connected to electric supply by a flexible cord and a plug;

f) maximum rated voltage not exceeding 250 V single-phase, a.c. or d.c., or 440 V three-phase, a.c.;

g) maximum rated input not exceeding 2 500 W, for single-phase a.c. or d.c., and 4 000 W for three-phase a.c.

NOTES

1 These tools are commonly known as "transportable motor-operated electric tools", hereinafter referred to, in the text, as tools. Examples of these.tools are given in the footnote.

2 Additional special driving mechanisms for cooling pumps and dustexhaust devices are allowed.

3 When tools are used in locations where special conditions prevail, for example explosive atmospheres or areas where hazards arising from dust and fire are likely to occur, special precautionary measures or special types of construction are necessary.

4 Multifunction tools that have clearly separate modes of Operation are required to comply separately with the requirements applicable to each specific mode of operation.

5 This standard does not apply to

- electric motor-operated household and similar electrical appliances according to IEC 335-1;

- hand-held electric motor-operated tools according to IEC 745-1;

- electrical equipment for industrial machine-tools according to IEC 204;

- small low voltage transformer operated bench tools intended for model making, e.g. radio controlled model aircraft or cars, etc.;

- food preparation machines.

This standard is concerned with safety and takes into account the influence on safety of components necessary to achieve a required degree of radio and television interference suppression.
