Members

Internationally active companies with their production sites located worldwide are members of the GSK Quality Assurance Association (Gütegemeinschaft) based in Germany.

The Statutes provide for ordinary members and supporting members.

Ordinary membership of GSK can be acquired by:

  • Any company that manufactures valves and fittings and carries out epoxy powder coating itself
  • Valve and fitting manufacturers who contract out epoxy powder coating to third parties who are ordinary members
  • Epoxy powder coating companies who coat valves and fittings
  • Companies who manufacture epoxy powder coating materials or who strive towards this

Any association or person representing business or the profession can become a supporting member if the Association recognises that they have a legitimate interest in its Quality Assurance.

Candidate members

Candidate members are companies who are members of GSK and have applied to carry the Quality Mark (Gütezeichen). Candidate members can only carry the Quality Mark (Gütezeichen) when they have passed the tests laid out in the Quality and Inspection Regulations, and the Quality Committee has informed the Executive Committee that the candidate member can be awarded the Quality Mark (Gütezeichen). The Executive Committee then grants permission to carry the Quality Mark (Gütezeichen) for a set period. The Quality Mark (Gütezeichen) may not be carried prior to this.

After the Executive Committee has upgraded a company’s status from candidate member to Holder of the Quality Mark (Gütezeichen), the company may carry the RAL-GZ 662 Quality Mark (Gütezeichen) for a set period of time, and it will receive the certificate and be listed on the internet with the relevant type of certification (product, process, or coating materials).

No records found.

Supporting member

Any association or person representing business or the profession can become a supporting member if the Association recognises that they have a legitimate interest in GSK’s Quality Assurance.
