Quality Control: The Assurance Panel Review

The ResponsibleSteel Assurance Panel has experience from across the globe in the steel sector, social and environmental issues as well as in auditing and certification.

The Assurance Panel plays a vital role in ensuring the rigour of certification decisions made by certification bodies. The Panel reviews the audit reports, requiring clarification or revision of conformity classifications and suggesting amendments where needed, and either supporting or disapproving of the certification recommendations. They are guided by the following questions:

  • Does the audit report contain enough detail for the certification body to take an informed certification decision?
  • Do the evidence and rationales provided in the audit report support the conformity classifications?
  • Is the certification recommendation conclusive?
