Welcome to the GNB-CPD website

The website of the Group of Notified Bodies for the Construction Products Directive

General aim and background to the CPD

The free movement of goods is central to the single European market, and the New Approach to product legislation and the Global Approach to conformity assessment are key to helping to achieve this.  They are intended to remove technical barriers to trade - without compromising health, safety and environmental aspects of a member state (MS). Though it is not a legal document, the European Commission's ‘Guide to the implementation of directives based on the New and Global Approach', ie the ‘Blue Book' or 'Blue Guide', provides comprehensive general guidance on the principles and implementation of new and global approaches.

The health and safety aspects are covered by the essential requirements (ERs) which are laid down in the Directives, whilst the technical barriers to trade refer to:

  • legislative barriers arising from the regulations of a member state (MS) - including de-facto regulations;
  • the technical specifications and codes of practice which support those regulations; and
  • the requirement to involve third parties - often specified and approved by a MS and associated with a national mark.

The Construction Products Directive (CPD) is often classed as one of the New and Global Approach Directives, though the CPD does differ in several important ways from other New Approach and Global Approach Directives. The aim of the CPD is to remove technical barriers faced by construction products when they cross national boundaries in Europe, by the use of:

  • a common technical specification,
  • an agreed level of involvement of approved third parties, ie notified bodies (NBs), to declare certain product characteristics for certain intended uses, and
  • a common national mark, ie the CE marking.

Notified Bodies for the CPD

Where the harmonised technical specifications (eg Annex ZA of harmonised standards) require a manufacturer to involve a third party before CE marking then that third party shall be a NB.  That is, notified by the MS of the body to the Commission as competent to do the tasks expected of it for specific harmonised technical specifications. These days the notification is done by MSs using a website, and the notifications appearing on the NANDO website*. The tasks a body can be notified for are:

  • a test body for some or all of the initial type testing (ITT),
  • a calculation body for some or all of the ITT,
  • a (factory) inspection body,
  • a factory production control (FPC) certification body, and
  • a product certification body.

Note:

  1. Bodies approved for writing European Technical Approvals (ETAs), which is another type of harmonised technical specification, are also notified as competent to the Commission and appear on NANDO*, but are called approval bodies (ABs) when they are writing ETAs and Guidelines for ETAs (ETAGs). This distinction between NBs (testing, calculation, inspection and certification bodies) and ABs (who write ETAs) is followed on this website - though most approval bodies are also NBs.
  2. This website is concerned with the work of NBs (testing, calculation, inspection and certification bodies).  The European Organization for Technical Approvals (EOTA)* addresses matters relating to the writing of ETAs and ETAGs, and the work of ABs.
NBs (and ABs) are European bodies, notified to the Commission by their member state (MS) as competent to undertake the tasks expected of them. Details of NBs (and their scope of notification) and ABs are available on a dedicated Commission website - NANDO*.

The Group of Notified Bodies for the CPD

The Group of Notified Bodies for the CPD (ie GNB-CPD) is the official Europe-wide organisation for NBs and those who are seeking notification. The GNB-CPD is recognised and supported by the Commission and MSs. The prime task of the GNB-CPD is to help ensure NBs work in an equivalent manner across Europe according to the CPD, harmonised technical specifications and approved guidance.
