The government accepts this recommendation in principle. Any claims made about a product's performance, including statements about its suitability for use in certain situations, must be clear, honest and evidenced. Test results relied on when placing a product on the market should be accessible and free of charge to those selecting and using the product. Further, the national regulator must have powers to mandate disclosure of any information relating to the testing process that it considers necessary to assure itself that a product complies with the law. We have published a construction products green paper alongside the response to the Inquiry that proposes extensive measures for system-wide reform, including measures to address product testing and conformity assessment.
