Accreditation

Procedure by which an authoritative body gives formal recognition that a body or person is competent to carry out specific tasks.

Agreed expert opinion

The results of a dialogue between a group of experts who are accepted by their peers as being knowledgeable in a particular fire test and the performance of products in that test. 

Such dialogue shall take place within a recognised and properly constituted forum of an institution of the EU. These agreed expert opinions are then transformed into rules that may form the basis of extended application.

Annex ZA

The Annex ZA of a harmonised standard informs on the relationship between the European Standard and the Essential Requirements of EU Directive 89/106/EEC, EU Construction Products Directive. 

The clauses of a harmonised European Standard, shown in the Annex ZA meet the requirements of the mandate given under the EU Construction Product Directive (89/106/EEC). Compliance with these clauses confers a presumption of fitness of the products covered by this annex for its intended use.

Attestation of Conformity system AoC system

The Attestation of conformity system is the system of procedures used to assess the conformity of a product with its product standard. 

For the building hardware items covered by a harmonised standard, the Attestation of Conformity system is shown in the Table ZA.2 of the Annex ZA of the product standard and it is: System 1: See CPD, Annex III point 2 (i), without audit-testing of samples

Co-existence period

A co-existence period will follow publication of the EN in the Official Journal of the European Union and the date of the beginning and the date of the end of the co-existence period are published in the NANDO web site. 

During this period, both a national standard and the EN can be used to demonstrate compliance. At the end of the co-existence period, the national standard will be withdrawn, and product performance will have to be quoted against EN. 

The co-existence period is normally 12 months. Products already in the supply chain before the end of the co-existence period will be considered to have already been ‘placed on the market’ and will not have to be removed after the period of coexistence.

While the rules of direct application are based on the results of a fire resistance or smoke control test, the extended application (EXAPs) rules are based on agreed expert opinions and/ the interpolation and extrapolation from a series of tests. 

The extended application (EXAPs) rules are defined in the part of EN 15269 relative to the doorsets having the same basic construction type end the same material as the considered doorset

Factory production control FPC

The manufacturer of a building hardware item covered by a harmonised standard shall establish, document and maintain an FPC system, in accordance with the requirements of the product standard, to ensure that the products placed on the market comply with the declared performance of the characteristics. 

The FPC system shall consist of procedures, regular inspections and tests and/or assessments and the use of the results to control raw and other incoming materials or components, equipment, the production process and the product. 

All the elements, requirements and provisions adopted by the manufacturer shall be documented in a systematic manner in the form of written policies and procedures.

Formal vote FV

Circulation by the CEN Management Centre of the final text of a prEN (FprEN) to CEN national members for approval through weighted voting.

Hardware performance sheet HPS

Harmonization Document HD

A Harmonization Document (HD) is a normative document made available by CENELEC in the three official languages. The elaboration of a HD includes a public enquiry, followed by an approval by weighted vote of CENELEC national members and final ratification. 

The Harmonization Document is announced at national level and every conflicting national standard is withdrawn. During the elaboration and whole lifetime of the Harmonization Document, standstill applies. 

The preparation, the approval and the review of an HD follow the same procedure as that given for an EN

Initial Type Testing ITT

The manufacturer of a product covered by a harmonised standard shall submit a sample representative of the products which will be placed on the market for a complete set of tests for Initial Type Testing. 

This is to prove that the product complies with the performance characteristics established in the product standard and that the performance declarations made by the manufacturer represent the true behaviour of the product.

National Standards Body

Standards body recognized at national level, that is eligible to be the national member of the corresponding international and regional (European) standards organizations

New approach directives

Directives that have been put into force since May 1985 by the Council of the European Communities which define 'legislative harmonization in those sectors where barriers to trade are created by justified divergent national regulations concerning the health and safety of citizens and consumer and environmental protection 

New approach directives will be confined to laying down the 'essential requirements', conformity with which will entitle a product to free movement within the Community.' 

New Approach Directives define the essential requirements that products must meet when they are put on the market, but, in contrast to the Old Approach Directives, do not include technical solutions to meet the essential requirements.

New Approach Directives foresee that the European Standards organizations (e.g. CEN), following a mandate given by the Commission, will elaborate harmonised European Standards (hEN), which will offer technical solutions to meet the essential requirements. 

The list of the new approach directives comprehends several directives among which:

  • Construction Products Directive (CPD) 89/106/EEC and following amendments
  • Electromagnetic compatibility (EMC) directive 2004/108/EC
  • Low voltage directive (LVD) 2006/95/EC Machinery directive (MD) 2006/42/EC and following amendments
New Approach Notified and Designated Organisations Information System NANDO Information System

Notification is an act whereby a Member State informs the Commission and the other Member States that a body, which fulfils the relevant requirements, has been designated to carry out conformity assessment according to a directive. 

Notification of Notified Bodies and their withdrawal are the responsibility of the notifying Member State. The Member States, EFTA countries (EEA members) and other countries with which the EC has concluded Mutual Recognition Agreements (MRAs) and Protocols to the Europe Agreements on Conformity Assessment and Acceptance of Industrial Products (PECAs) have designated Notified Bodies, established per directive. 

Lists of Notified Bodies can be searched on the NANDO web site. The lists include the identification number of each notified body as well as the tasks for which it has been notified, In the NANDO web site it is also available a list of the harmonised standards under the CPD which advises the applicability date and the co-existence period end date of each harmonised standard. 

Find out more on NANDO website.

No performance determined NPD

The requirement on a certain characteristic of a harmonised standard is not applicable in those Member States (MSs) where there are no regulatory requirements on that characteristic for the intended use of the product. 

In this case, manufacturers placing their products on the market by these MSs are not obliged to determine nor declare the performance of their products with regard to this characteristic and the option “No performance determined” (NPD) in the information accompanying the CE marking (see ZA.3) may be used. 

The NPD option may not be used, however, for durability and where the characteristic is subject to a threshold level.

Notified Body

Notification is an act whereby a Member State informs the Commission and the other Member States that a body, which fulfils the relevant requirements, has been designated to carry out conformity assessment according to a directive. 

Notification of Notified Bodies and their withdrawal are the responsibility of the notifying Member State.
