particular Article 100a thereof, 
Having regard to the proposal from the Commission, 
in cooperation with the European Parliament, 
Having regard to the opinion of the Economic and Social Committee, 
Whereas the introduction of harmonized methods for the assessment of conformity and the 
adoption of a common doctrine for their implementation is likely to facilitate the adoption of 
future technical harmonization directives, the placing on the market of industrial products and 
thus be conducive to the completion of the internal market by 31 December 1992, 
HAS ADOPTED THIS DECISION: 
Sole Article 
The modules for the various phases of the procedures for conformity assessment which are to 
be used in the technical harmonization Directives relating to the marketing of industrial 
products will be chosen from among those listed in the Annex to this Decision and in 
accordance with the criteria set out therein.

ANNEX 
CONFORMITY ASSESSMENT PROCEDURES IN THE TECHNICAL HARMONIZATION 
DIRECTIVES 
I. General guidelines 
The principal guidelines for the use of conformity assessment procedures in the technical harmonization 
Directives are the following: 
(a) the essential objective of a conformity assessment procedure is to give to the users, consumers and 
public authorities, the assurance that products placed on the market conform to the various 
requirements expected of them as these are expressed in the provisions of the Directives; 
(b) conformity assessment can be subdivided into modules which relate to the control of the design 
phase of products or to the control of their production phase; in certain specific cases these two 
functions are so inseparable they must be combined to constitute a module (e.g. modules A, G and 
H); 
(c) as a generale rule a product should undergo a control in both phases before being able to be placed 
on the market if the results are positive; 
(d) there are a variety of modules which cover the two phases in a variety of ways. The Directives shall 
set the range of possible choices which can be considered by the Council to give the public auth­
orities the acceptable level of safety they seek, for a given product or product sector; 
(e) in setting the range of possible choices open to the manufacturer, the Directives will take into 
consideration, in particular, such issues as the appropriateness of the modules to the type of 
products, the nature of the risks involved, the economic infrastructures of the given sector (e.g. 
existence or non-existence of third parties), the types and importance of production etc; 
(f) the Directives will set out the requirements governing the conditions in which the manufacturer 
makes his choice as to the most appropriate modules for his production; 
(g) the Directives should, in setting the range of possible modules for a given product or product 
sector, attempt to leave as wide a choice to the manufacturer as is consistent with ensuring an 
acceptably high level of protection, as laid down by the essential requirements; the Directives 
should avoid imposing unnecessary modules which would be too onerous relative to the objectives 
of the Directive concerned; 
(h) notified bodies should be encouraged, whenever possible, to apply the modules without undue 
burden for the economic operators in order to ensure consistent interpretation and application of 
the modules. The European Organization for Testing and Certification or, in its absence, the 
Commission will organize close cooperation between the notified bodies; 
(i) whenever Directives provide the possibility for the manufacturer to use quality assurance 
techniques, they must also wherever possible provide for the possibility of recourse to product 
certification; 
(j) for the purposes of operating the various modules, Member States shall notify only competent 
bodies which comply with the requirements of the Directives; bodies accredited to apply the EN 
45 000 series or which can produce documentary evidence that they conform to the EN 45 000 
series shall be considered to conform to the requirements of the Directives. Member States which 
do not notify accredited bodies shall be invited to produce the documentary evidence that they 
conform to the requirements of the Directive; 
(k) lists of notified bodies shall be published by the Commission in the OJEC and constantly updated; 
(1) the CE mark (accompanied, wherever appropriate, by the identification symbol of the third party 
involved in the control of the production phase) shall be affixed to show that the production phase 
has been carried out satisfactorily only having regard to the requirements of the Directives. 
II. Modules for conformity assessment 
Explanatory notes 
Specific directives may allow the CE mark to be affixed to the packaging or the accompanying docu­
mentation, instead of to the product itself. 
8. 9. 89 Official Journal of the European Communities No C 231/5 
The declaration of conformity or the certificate of conformity (whichever of the two applies in the 
directive concerned) shall cover either individual or several products and shall either accompany the 
product(s) covered or be kept by the manufacturer. The appropriate solution for the directive 
concerned will be specified. 
References to articles refer to the standard paragraphs of Annex II B of the Council resolution of 
7 May 1985 (OJ No C 136 of 4 June 1985 p. 1), and which have become standard articles in the New 
Approach Directives. 
The development of computerized telecommunications as a means of publication of certificates issued 
by notified bodies is envisaged within INSIS. 
Specific directives may use modules A, C and H with additional sections containing supplementary 
requirements (which figure in the boxes in the modules). 
Modules C and D are designed to be used in combination with module B (EC type examination). 
Modules E and F will also normally be used in combination with module B; however, in special cases 
(for example when dealing with certain products of very simple design and construction) they may be 
used on their own. 
MODULE A 
EC DECLARATION OF CONFORMITY 
1. The EEC declaration of conformity is the procedure whereby the manufacturer or his authorized 
representative established within the Community ensures and declares that the products concerned 
satisfy the requirements of the directive that apply to them. The manufacturer shall affix the CE 
mark to each product and draw up a written declaration of conformity. 
2. The manufacturer shall establish the technical documentation described in paragraph 3 and he or his 
authorized representative established within the Community shall keep it for a period ending at least 
10 years (') after the last product has been manufactured at the disposal of the relevant national 
authorities for inspection purposes. 
Where neither the manufacturer nor his authorized representative is established within the 
Community, the obligation to keep the technical documentation available shall be the responsibility 
of the person who places the product on the Community market. 
3. The technical documentation shall enable understanding of the design, manufacture and operation 
of the product, and shall enable assessment of conformity with the requirements of the directive. 
The documentation shall contain so far as relevant for assessment:
