25.080.50 - Grinding and polishing machines

This document applies to stationary surface-finishing machines with stationary work piece (see 3.1) or with moving work piece (see 3.2) which are used to grind or polish horizontal surfaces of slabs, strips or tiles of natural stone and engineered stone (e.g. agglomerated stone) as defined by EN 14618:2009.
This document deals with all significant hazards, hazardous situations and events relevant to surface-finishing machines, when they are used as intended and under conditions of misuse which ...view more

Next steps: the formal vote of the European Amendment
2019-08-08 JF: The Annex ZZ was delivered after the Enquiry started. The need to adapt the Annex ZZ.

2018-11-02: this prA covers common mods to EN 62841-3-4:2016/prA1:2018 (pr=67898)

The document specifies, with reference to ISO 230-1 and ISO 230-2, geometric tests, machining tests and tests for accuracy and repeatability of positioning axes on general purpose and normal accuracy manually and numerically controlled (NC) external cylindrical centreless grinding machines. It also specifies the applicable tolerances corresponding to the above-mentioned tests. This document deals only with the verification of accuracy of the machine. It does not apply to the testing of the machi...view more

This Standard specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held power-driven angle and vertical grinders. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of a machine fitted with a specified test wheel and run under no-load conditions. The method has been established for surface grinding tasks only. Cutting and sanding generally create lower vibrations. It is intended that the results be used ...view more

1.1   General
This European Standard specifies general requirements for the dust measurement of electric motor-operated tools supplied from mains or from batteries. This standard applies to those tools with and without dust extraction unit where dust such as mineral dust containing silica or wood dust is expected.
1.2   Types of dust
Dust is a disperse distribution of solid substances in gases, particularly air, resulting from mechanical processes. According to EN 481, two size categories are to ...view more
