All Accredited laboratories will, on an annual basis, be subjected to examination by external auditors; where any non-compliances (for example, incorrect interpretations of test methods), can result in the loss of a laboratory's approved status.RAH Consultancy has had a long standing relationship with KIWA Watertec. We undertake internal auditing of their test rigs and laboratory procedures. These internal audits benefit laboratories by giving their staff valuable experience in correct procedures required in undertaking of their duties.
