Third party certification
placement activity under the Construction Product’s Regulation, (and not third party certification as described above), there is limited third party involvement with respect to issuing the certificate of constancy of performance (COCOP) and ongoing surveillance (not site or installation related). The declaration of performance (DOP) will also assist the end user in identifying the performance capabilities of the product as appropriate for the required end use.
◊ In the case of a standardised product that is not covered by a hEN, compliance with the performance requirements of the building regulations can be demonstrated using a relevant non harmonised European standard, British standard or ISO standard. The manufacturer may declare conformance against the standard by first party certification (self certification) or as part of a third party certification scheme.
◊ For non standardised products (eg not covered by a hEN), there is the option for demonstrating the performance of certain products by way of a European Technical Assessment (ETA) conducted by a Technical Assessment Body (TAB), providing there is a European Assessment Document (EAD) for the product. In essence it is a route for CE marking construction products if a hEN does not exist. As for CE marking under the hEN route, it is not the same as third party certification, but there is input from an independent notified body, in terms of writing the ETA and issuing the
COCOP for the manufacturer to prepare a DOP and place a CE mark on the product ready for sale.
◊ With regard to non standardised products that do not have a relevant EAD, there are other routes for demonstrating compliance, such as test evidence generated using normative standards, calculations, or assessments of performance based on test evidence. The product is manufactured in accordance with the supporting documentation, and the assurance of compliance can be given by the manufacturer as a first party certification activity via a second party certification activity, or as part of a third party certification scheme. In the case of third party certification schemes, the certification body will make the decision about what supporting documentation is acceptable for the manufacturer to use as a basis for constructing the product as part of the certification scheme. Typically, this will be either engineering assessment documents that extend the field of application of any test evidence (written by organisations with demonstrable competence in the field of assessment writing), or directly relevant test evidence generated to normative standards at UKAS accredited laboratories. To maintain impartiality regarding certification decisions and to avoid any conflict of interest, ISO 17065 requires that certification bodies must be independent from the test laboratory and engineering assessment organisation.
