In order to demonstrate compliance, MPA Cement's Member Companies are all participants in a Kitemark Verification Scheme developed by BSI Assessment and Certification. This Scheme is based on the provisions in normative Annex A of BS EN 196-10 'Evaluation of the compliance of cement with the regulatory limit in Directive 2003/53/EC [now REACH] on water-soluble hexavalent chromium content'. The test method used is described in the same European Standard.
