1 Scope This European Standard is applicable to the following coated abrasive products: flap wheels, flap discs, vulcanised fibre discs and spindle mounted flap wheels. It also applies to back-up pads for vulcanised fibre discs.
This European Standard specifies requirements and/or measures for removal or reduction of hazards resulting from the design and application of the coated abrasive products and clamping devices. This European Standard also contains procedures and tests for verification of compliance with the requirements as well as safety information for use, which is to be made available to the user by the manufacturer. The hazards taken into consideration are listed in Clause 4 of this standard. This European Standard does not apply to non-woven web abrasive products, bonded abrasive products and superabrasive products. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 554, Standard atmospheres for conditioning and/or testing — Specifications 3 Terms, definitions and symbols For the purpose of this document the following terms and definitions apply. 3.1 General 3.1.1 coated abrasive product abrasive product composed of backing, abrasive particles and bond and optionally a supporting element
NOTE Examples for supporting elements are pads and spindles. 3.1.2 clamping device device for fixing and positioning the abrasive product on the spindle of the grinding machine
NOTE Clamping devices include e.g. back-up pads for vulcanised fibre discs, and clamping flanges for flap wheels. 3.2 Grinding machines 3.2.1 stationary grinding machine grinding machine being fixed in position during operation NOTE See for example EN 13218. 3.2.2 mobile grinding machine grinding machine not being fixed in position during operation NOTE Mobile grinding machines are manually guided (but not supported) by hand during use, e.g. floor grinding machines.
