Proposal for a

COUNCIL DECISION

on the procedure for attesting the conformity of construction products pursuant
to Article 20(2) of Council Directive 89/106/EEC as regards flat glass, profiled
glass and glass block products

(presented by the Commission)

EXPLANATORY MEMORANDUM

Summary

1. Council Directive 89/106/EEC of 21 December 1988 on the approximation of
laws, regulations and administrative provisions of the Member States relating to
construction products, seeks to abolish those obstacles to the free movement of
goods which are caused by the disparity of national product standards, technical
approvals or other technical specifications and provisions that reflect safety and
other requirements important in the public interest that are subject to national
laws, regulations or administrative provisions.

2. To this end, the Directive provides, inter alia, that the Commission is to prepare
mandates which form the basis for CEN/CENELEC to elaborate harmonised
standards. The conformity of the products with these harmonised standards gives
these products the presumption of fitness for their intended use.

3. The attestation of the conformity of the products with harmonised standards
(or other harmonised specifications) is established following several alternative
procedures. According to Article 13(4), the choice of the procedure for the
attestation of conformity for a given product or family of products is specified by
the Commission after consultation of the Standing Committee referred to in
Article 19(1). More specifically, the procedure for the attestation of conformity is
laid down in a decision in the sense of Article 249 of the EC Treaty, whereby
Article 20 of the Directive 89/106/EEC has to be followed.

4. When establishing its decision proposals, the Commission follows the specific
technical criteria related to in Article 13(4) of the Directive and takes into account
the principle of the least onerous possible procedure consistent with safety
referred to in the same article, as well as the general principle of proportionality.

5. Due to its complexity, which causes delays in implementation, and the burden that
the attestation procedures could impose on manufacturers, the Directive was part
of the first SLIM initiative which concluded that both the acceleration of its
implementation and the improvement/simplification of
the Directive itself
were needed. For the same reason the Commission, whilst strictly applying the
criteria referred to above, pays special attention to all operational aspects of the
procedures required for the attestation of conformity, whose cost could sometimes
result in significant alterations in competition conditions on the market, generally
to the prejudice of SMEs.

6. Bearing all this in mind, on 2 December 1997, the Commission presented to the
Standing Committee on Construction a draft for a decision on the attestation of
conformity concerning six families of glass products. In the presence of all
Member States, 53 votes were delivered against the draft and 34 for the draft of
the Commission. The minutes of
some
representatives voted against the draft because a more stringent procedure for the
attestation of conformity should have been chosen for product group 5/6 (in short:
insulating glass units). As the measures envisaged by the Commission are not in

the relevant meeting show that

accordance with the opinion of the committee, the Commission is now submitting
the proposal to the Council according to Article 20(2) of Directive 89/106/EEC.

I.

Introduction

In the framework of the Construction Products Directive (CPD), the availability of
harmonised standards is a more important element for the functioning of the internal
market than in other new approach directives. In the case of the CPD as it is now,
harmonised technical specifications (standards or European technical approvals) are
de facto compulsory, as direct conformity with the essential requirements is excluded
as an alternative route to CE Marking, for the simple reason that no essential
requirements are defined by the directive at the level of construction products.

In this case, the second important element for the operation of a new approach
directive on the market, the attestation of conformity, necessarily refers to the
available technical specifications, instead of to the essential requirements themselves.
For this reason and because of the great variety of products and products families, the
Directive does not foresee a specific procedure for the attestation of conformity.

family of products, after consultation of

Following the same Article 13, in each case, the least onerous possible procedure
consistent with safety shall be chosen. In addition, the Commission takes account as
far as possible of the principles of simplification and efficiency referred to in the
SLIM initiative, as well as of the general principle of proportionality.

It appears that for the family of insulating glass units, the Standing Committee
referred to above, does not share the Commission’s opinion on these aspects, and thus
the measures envisaged are not in accordance with the opinion that the Standing
Committee delivered on 2 December 1997.

II.

Procedural aspects in relation to the draft from the Commission to the
Standing Committee in relation to the attestation of conformity for
flat glass, profiled glass and glass blocks

(a)

The decision within the system of the Directive 89/106/EEC

Directive 89/106/EEC foresees, inter alia, that the Commission prepares mandates
which form the basis for CEN/CENELEC to elaborate harmonised standards.
Furthermore, the Commission has to elaborate a draft for a decision which fixes in
which manner a construction product is to be tested in order to allow attestation of the
fact that the product is in conformity with the requirements of the harmonised norm.
There are two procedures for the attestation of conformity to be chosen from: either

3

the manufacturer controls via its own factory production control1, or an approved
body is additionally involved in the assessment and surveillance (Article 13(3)). In
each case the least onerous procedure consistent with safety shall be chosen
(penultimate paragraph of Article 13(4). The criteria listed in Article 13(4) will help
in the decision making process.

The procedure for the attestation of conformity is laid down in a decision in the sense
of Article 249 of the EC Treaty, whereby Article 20 of Directive 89/106/EEC has to
be followed. Therefore, the Commission submits a draft to the Standing Committee
which has to deliver an opinion with the majority laid down in Article 205(2) of the
EC Treaty. The Committee is a regulatory Committee according to procedure III of
the Council decision of 13 July 1987 laying down the procedures for the exercise of
implementing powers conferred on the Commission2.

(b)

Opinion of the Standing Committee on the draft of the Commission

On 2 December 1997 the Commission presented the said draft for a decision to the
Standing Committee. In the presence of all Member States, 53 votes were delivered
against the draft and 34 for the draft of the Commission3. The minutes of the relevant
meeting shows that some representatives voted against the draft because a more
stringent procedure for the attestation of conformity should have been chosen for
product group 5/6 (in short: insulating glass units).

As the measures envisaged by the Commission are not in accordance with the opinion
of the committee, the Commission is now submitting the proposal to the Council
according to Article 20(2) of Directive 89/106/EEC.

III. Material aspects in relation to the proposal from the Commission to the
Council with regard to the procedure of attestation of conformity for
flat glass, profiled glass and glass blocks

(a)

The proposed procedures of attestation of conformity

Annex I and II of the Directive reflect in a general way the procedures of attestation
of conformity. The final choice is laid down in Annex III which fixes for each product
in its end-use the procedure of attestation of conformity which is to be applied.

Directive 89/106/EEC defines in Annex III.1 the factory production control as a permanent
internal control of production exercised by the manufacturer. 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. This production control system documentation shall ensure a
common understanding of quality assurance and enable the achievement of the required product
characteristics and the effective operation of the production control system to be checked.
OJ L 197, 18.7.1987, p. 33.
Belgium, Germany, Spain, France, Italy, Luxembourg, Portugal and Finland voted against the
draft of the Commission. Denmark, Greece, Ireland, the Netherlands, Austria, Sweden and the
United Kingdom voted for the draft of the Commission.

1.

The least onerous procedure4

The least onerous procedure has been chosen for three end uses. Either the product
falls under:

(1)

(3)

2.

fire class A according to decision 96/603/EC of the Commission5, or under
fire classes D,E,F of decision 94/611/EC of the Commission6 (Product family
2/6). The proposal thereby follows the classifications taken in the above
mentioned decisions; or

the decision of the Commission which will be taken in the area of external fire
performance analogous to Decision 96/603/EC (product family 3/6); or

all end-uses not explicitly listed in the decision (product family 6/6).

The additional involvement of an approved body7

The additional involvement of an approved laboratory in order to execute an initial
type test has been chosen for the following products:

(1)

(2)

(3)

(4)

3.

products which fall under fire classes A,B,C of decision 94/611/EC of the
Commission (product family 2/6). Thereby,
the Commission follows the
classification used in the abovementioned Decision; or

products for uses which are subject to external fire performance regulations.
(product family 3/6). Thereby, the Commission follows the decision which
will be taken in the area of external
fire performance analogous to
Decision 96/603/EC; or

products which serve as safety glass (product family 4/6); or

products which serve as insulating glass (product family 5/6).

Additional involvement of an approved body with increased testing and
surveillance responsibilities8

For justified exceptional cases a system has been chosen which requires the
involvement of an approved certification body not only for the initial type test of the
product but also for an initial inspection of the factory, an initial inspection of the
factory production control of the producer and continuous surveillance, assessment
and approval of the factory production control. This financially and logistically
intensive procedure for the producer is foreseen for products which:

The procedure of attestation of conformity for insulating glass

The proposal of the Commission takes into account the SLIM initiative and is based
on the legal grounds of the EC Treaty and Directive 89/106/EEC. As the Commission
has to choose the least onerous procedure consistent with safety, it must follow the
principle of proportionality. Therefore, the procedure must not go beyond what is
necessary to achieve the objectives. The attestation of conformity by the producer
himself has to be given priority. This fundamental principle has only to be left aside if
it is imperative for reasons of safety.

The principle of proportionality for the procedure of attestation of conformity in the
case of Directive 89/106/EEC has to be assessed against the question of whether the
chosen procedure can secure those characteristics of a construction product which a
construction works needs in order to fulfil the essential requirements in the sense of
Directive 89/106/EEC.

Insulating glass has the task to enable the construction works to fulfil the essential
requirements “Protection against noise” and “Energy economy and heat retention”.
Protection against noise is laid down in Annex I point 5 of Directive 89/106/EEC
as follows:

The construction works must be designed and built in such a way that noise perceived
by the occupants or people nearby is kept down to a level that will not threaten their
health and will allow them so sleep, rest and work in satisfactory conditions.

In order to fulfil “Energy economy and heat
Directive 89/106/EEC foresees that

retention” Annex I point 6 of

The construction works and its heating, cooling and ventilation installations must be
designed and built in such a way that the amount of energy required in use shall be
low, having regard to the climatic conditions of the locations and the occupants.

The satisfaction of the essential requirements is assured by a number of interrelated
measures, in particular the planning and design of the works, the execution of the
works and necessary maintenance as well as the properties, performances and use of
the construction products9. One of these products could be insulating glass. Insulation
glass units help to reduce direct airborne sound10 and the energy needs of construction
works. To these ends several characteristics will need to be tested as laid down in a
thermal properties and
harmonised standard: direct airborne sound insulation,
radiation properties11.

With regard to the production process of insulating glass it needs to be explained that
sheets of glass units are assembled which contain either air or inert gases between
them and/or have a special coating.
Important aspects in the production of
multi-layered glass units are the sealing and a complete surface treatment in the case
of coating. Faults in the design or in the fabrication lead to a reduced technical
capacity of the product which has negative repercussions on the fulfilment of the
essential requirements as described above.

The importance of the product “insulating glass” as one of several possibilities to
fulfil the essential requirements “noise reduction” and “energy economy and heat
retention” in the construction works, is to be regarded as notable yet not essential.
This also means that the effect of the variability of the products characteristics on its
serviceability with regard to the fulfilment of the essential requirements is medium to
low. However, the production process does bear the possibility of defects. A poor
sealing will leave a simple multiple-glazing. A coating which has not been applied in
full or which becomes patchy, is less effective in reducing the energy needs of the
construction works. In order to contain these risks, the Commission proposes to have
the design and production parameters tested with a prototype by an independent test
laboratory. The producer will then have to follow the test results of the initial type test
with his own production control system.

In general it has to be noted that the principle of proportionality is not always
followed by the majority of representatives of the Member States in the administrative
committee. Neither the EC Treaty and the explicit provision in article 13(4) of
Directive 89/106/EEC, nor the efforts of the Commission to elaborate a legislation
which is
convinced the majority of
for manufacturers,
representatives in the administrative committee to find a legally objective and
acceptable result. In the case in question, the Member States even asked for a degree
of involvement of a third party that does not exist in their own national legal order.
The law of the European Community is thus being misused in order to introduce more
stringent rules for market participants.

the least onerous

With such behaviour,
the objectives of Directive 89/106/EEC are constantly
undermined, which is neither acceptable in a legal nor an economic sense. The
tendency to foresee more stringent, and thereby more expensive procedures for the
attestation of products via a systematic involvement of a third party is not covered
by the text of the Directive and does not correspond to the approach of the
European Community in order to fulfil the Internal Market in the EC; furthermore, it
does not in any way reduce production costs and thereby improve competitiveness.

Having regard to the proposal from the Commission14,

Whereas:

(1) The Commission is required to select, as between the two procedures under
Article 13(3) of Directive 89/106/EEC for attesting the conformity of a product,
the 'least onerous possible procedure consistent with safety'. This means that it is
necessary to decide whether, for a given product or family of products, the
existence of a factory production control system under the responsibility of the
manufacturer
is a necessary and sufficient condition for an attestation of
conformity, or whether, for reasons related to compliance with the criteria
mentioned in Article 13(4), the intervention of an approved certification body is
therefore required.

(2) Article 13(4) requires that the procedure thus determined must be indicated in the
mandates and in the technical specifications; therefore, it is desirable to define the
concept of products or family of products as used in the mandates and in the
technical specifications.

(3) The two procedures provided for in Article 13(3) are described in detail in
Annex III to Directive 89/106/EEC: it is necessary therefore to specify clearly the
methods by which the two procedures must be implemented, by reference to

set out in the first possibility, without continuous surveillance, and the second and
third possibilities of point (ii) of Section 2 of Annex III, and the procedure
referred to in point (b) of Article 13(3) corresponds to the systems set out in
point (i) of Section 2 of Annex III, and in the first possibility, with continuous
surveillance, of point (ii) of Section 2 of Annex III.

Article 1

The products and families of products set out in Annex I shall have their conformity
attested by a procedure whereby the manufacturer has under its sole responsibility a
factory production control system ensuring that the product is in conformity with the
relevant technical specifications.

Article 2

The products set out in Annex II shall have their conformity attested by a procedure
in addition to a factory production control system operated by the
whereby,
manufacturer, an approved certification body is involved in assessment and
surveillance of the production control or of the product itself.

Article 3

The procedure for attesting conformity as set out in Annex III shall be indicated in
