Safety requirements for handheld non-electric power tools Part 8: Grinders and polishers

1 Scope

This document stipulates the requirements for sand-covered items, various soft material products and seamless transmission in motion modes such as rotation, orbit and reciprocation:

Safety requirements for hand-held non-electric power tools with moving belts for polishing and polishing (hereinafter referred to as "sanders and polishers"): Grinders and Polishers the light machine can be driven by compressed air, hydraulic oil or internal combustion engine, with or without the use of suspension devices (such as balancing devices), for one person the operator can use it with one or two hands:

NOTE 1: At the time of publication of this document, the existence of grinding and polishing machines powered by internal combustion engines was not known to exist: Once this type of machine is confirmed, this document will be Revised to incorporate it:

This document applies to the following products:

--Belt grinder;

--Skateboard polisher;

--polisher;

--Compound polishing machine;

--Rotary polishing machine;

--Linear polishing machine:

Note 2: See Appendix B for examples of grinders and polishers:

This document does not apply to special requirements and modifications of grinders and polishers for mounting them on clamping devices:

This document covers use of grinders and polishers other than those used in potentially explosive atmospheres, their intended use and misuse reasonably foreseeable by the manufacturer:

All noteworthy hazards, dangerous situations or hazardous events when using the tool under the conditions in which it was used:

Note 3: EN 13463-1 gives requirements for the use of non-electrical equipment in potentially explosive atmospheres:
