The oSa®-trademark – Your sign of comprehensive safety

Three standards form the pillar of the oSa safety philosophy:

  • EN 12413 Safety requirements for Bonded Abrasives
  • EN 13236 Safety requirements for Superabrasives
  • EN 13743 Safety requirements for Coated Abrasives

Generally, although these standards are not mandatory, this is not the case for oSa-members. Upon admission to oSa, all members undertake to accept the EN-standards as binding, to comply with them and to fulfil the requirements stipulated therein.

The oSa-trademark however provides further assurances:
