Safety requirements for coated abrasive products

This European Standard is applicable to the following coated abrasive products and a combination of coated and non-woven 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. These products are manufactured using the following abrasive grains: aluminium oxide, silicon carbide, diamond, or CBN.
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 abrasive products entirely of non-woven web.

Prescriptions de sécurité pour les produits abrasifs appliqués

La présente Norme européenne est applicable aux produits abrasifs appliqués suivants et à une combinaison de produits abrasifs appliqués et non tissés : roues à lamelles, disques à lamelles, disques en fibre vulcanisée et roues à lamelles sur tige. Elle s’applique également aux supports de disques en fibre vulcanisée. Ces produits sont fabriqués en utilisant les grains abrasifs suivants : oxyde d'aluminium, carbure de silicium, diamant ou CBN.
La présente Norme européenne spécifie les prescriptions et/ou les mesures pour la suppression ou la réduction des phénomènes dangereux résultant de la conception et de l’utilisation des produits abrasifs appliqués et des dispositifs de fixation.
La présente Norme européenne contient également les modes opératoires et les essais pour la vérification de la conformité aux exigences aussi bien que les informations de sécurité pour l’utilisation, que le fabricant doit fournir à l’utilisateur.
Les phénomènes dangereux à prendre en considération sont donnés à l’Article 4 de la présente norme.
La présente Norme européenne ne s’applique pas aux produits abrasifs entièrement en toile non tissée.

Varnostne zahteve za brusna sredstva na podlagah

Kot v obstoječem standardu EN 13743): ta evropski standard se uporablja za naslednja brusna sredstva na podlagah: pahljačasta kolesa, pahljačaste kolute, kolute z vulkaniziranimi vlakni in pahljačasta kolesa na vretenu. Uporablja se tudi za varnostne blazinice kolutov z vulkaniziranimi vlakni. Ta evropski standard določa zahteve in/ali ukrepe za preprečevanje ali zmanjševanje tveganj, ki izhajajo iz oblikovanja in uporabe brusnih sredstev na podlagah in vpenjalnih naprav. Ta evropski standard vsebuje tudi postopke in preskuse za preverjanje skladnosti z zahtevami ter varnostne napotke za uporabo, ki jih uporabniku ponuja proizvajalec. Nevarnosti, ki jih je treba upoštevati, so navedene v točki 4 tega standarda. Ta evropski standard se ne uporablja za netkana mrežna brusilna sredstva, vezana brusilna sredstva in superabrazivne izdelke.

Overview

EN 13743:2017 - Safety requirements for coated abrasive products (CEN) defines safety, testing and information requirements for a range of coated abrasives used in grinding and finishing operations. It applies to flap wheels, flap discs, vulcanised fibre discs, spindle-mounted flap wheels and back-up pads (for vulcanised fibre discs) made with aluminium oxide, silicon carbide, diamond or CBN grains. The standard specifies design and manufacturing controls, marking, user information and verification tests to reduce hazards such as ejection of parts, dust/particles, contact and vibration.

Key topics and technical requirements

• Scope and product types: Covers coated abrasive products and combinations of coated/non-woven products listed above; excludes fully non-woven web abrasives.
• Design & manufacture: Products must resist expected forces and show no visible safety-affecting defects.
• Maximum operating speeds: Specifies a sequence of permitted peripheral speeds (e.g., 16, 20, 25, 32, 35, 40, 45, 50, 63, 80 m/s) and conversion guidance to rotational speed (Annex C).
• Safety factors:
  • Typical burst safety factor Sbr = 3 for many products; Sbr = 3.5 for some back-up pads and certain size/usage conditions.
  • Spindle deflection safety factor Sab = 1.3 for spindle-mounted flap wheels.
• Verification & testing:
  • Visual inspection for defects.
  • Centrifugal/bursting speed test (mounted on a test rig) to determine bursting speed and verify safety factors; rotational speed measurement accuracy ±1%.
• Marking & user information: Marking requirements (Annex A), colour codes (Annex B) and manufacturer-supplied safety/use information are mandatory to ensure correct selection and mounting.
• Hazard list: Clause 4 lists significant hazards (ejection of parts, grinding debris/dust, vibration, contact, noise) and references Clause 7 for use/handling mitigations.

Applications - who uses EN 13743:2017

• Manufacturers and suppliers of flap wheels, flap discs, vulcanised fibre discs and back-up pads - for design, QA and CE / national conformity.
• Importers and distributors - to verify marking, information for use and compliance.
• Machine builders and safety engineers - to select compatible abrasives that help meet Machinery Directive and General Product Safety requirements.
• Test labs and QC teams - to perform bursting/centrifugal tests and visual inspections.
• End users (industrial workshops, metalworkers, grinders) - rely on the standard’s marking and information to choose safe products and operating speeds.

Related standards

• References in EN 13743:2017 include ISO 554 (conditioning/testing atmospheres) and cross-references to machine and tool standards (e.g., EN ISO 16089, EN ISO 11148 series) relevant for machine compatibility and safe operation.
