1. Introduction ^: ' . ...

.• The general programme of the Council of 28 May 1969 for file' removal of > ■ technical barriers to trade mentions the sector of electrical apparatus ^ •

'for use in potentially explosive atmospheres as one in which action .

■ should be taken to approximate national legislation pursuant to Article 100

of the Treaty, in order to eliminate existing disparities between the . technical specifications for manufacture. . ' _ . '

Council Directive 76/117/SEC of 18 December 1975 on the approximation of -

the laws of the Member States concerning electrical equipment for use' in ^; potentially explosive atmospheres (1) excluded electrical apparatus ,

- (Group I) for use in gassy mines as this apparatus_can be made 3ub1ect to _

' Community recommendations drawn up by the Safety and Health Commission for '

• the Mining and other Extractive Industries in Luxembourg. ,

Meanwhile Council Directive 79/¹96/RRC of 6 February 1979 on^- the approximation of the laws of the Member States concerning electrical equipment

• for use in potentially explosive atmospheres employing certain types of

• protection (2) which provides for the application of the above mentioned '

'•Directive has been adopted. . ' ~ ; ■ '

3y its terms of reference of 6 February 1973 as later amended on 22 January 1974 the Safety and Health Commission for the Mining and other Extractive Industries requested its Working Party on Electricity to prepare, ¹in close collaboration with the Commission departments, a draft proposal for a directive adapting the aforementioned Directive to make it applicable .

to electrical apparatus fdr use in potentially explosive atmospheres in 'gassy mines. • ■ _ ' ■ . . ' • . ^

Furthermore the above mentioned Safety and Health Commission requested its Working Party on Electricity to examine the European Standards (EN) ■ ■ - .

and to modify and to complete them if this should be. necessary.

The Safety and Health Commission for the Mining and other Extractive Industries adopted on 1 December 1978 the drafts for the present Proposal for a .

■ . Directive and its Explanatory Memonrandum which were prepared by its Working Party on Electricity. .

2. General comments on the Proposal for a Directive ■ -

Free circulation within the whole Community ie guaranted only for electrical apparatus fulfilling the provisions of the present Directive.

The technical specifications with which electrical apparatus must comply are. contained in harmonized standards which are identical to the European standards of the European Commit-tee for Electrotechnical Standardisation (CE2TELEC), except when amended by the annexes of the Directive.

Optional harmonization has been adopted since it enables national standards , and harmonized standards to coexist. :

3. Commgnxs on articles of the proposal for a Directive .

. - . \ ' • • . .

Articles 1 and 2 give the scope of the Directive and define-electrical apparatus.

The determination of those parts referred to in Article 3 depends on local-

■ . - '

conditions and is left to the competence of national authorities; possible differences between these determinations do not constitute a barrier to trade. .

Article A (1 ) specifies that only safety against ignition of firedamp is to be xaksn into account as the scope of the harmonized standards of construction is .

limited to this. The specifications of construction which take into account oxher aspects of safety must eventually rest with national standards insofar as such standards are not harmonized. _v .

N • \ / ' ~

fFor free circulation in Member States electrical apparatus must either conform to harmonized standards (certificate of conformity) or must assure a degree of safety at least equivalent (inspection certificate). '

Article A (3) requires that the laws, regulations and administrative provisions . of States of destination must not for reasons of safety in firedamp introduce a total barrier on the use of certain electrical apparatus having a certificate of conformity or of inspection. Since reference is made to harmonized standards

• x ' - -

■ in Article A (4) it is necessary to define these. .

The harmonized standards to which a type of Group I apparatus must conform

are the European Standards, 1st edition March 1977' with the references

SIT pO 014 to 50 020.as amended by Annexes 1, 2 and 3 of the Directive. .

Amendments to the harmonized standards listed in Article 4(4) would be adopted by the Commission under the procedure in Article 7 tout ^any new harmonized . standards would be adopted by the Council. . -

The rules ox" procedure of the Committee mentioned in Article 6 would establish, the methods to be followed to accomplish the tasks set out in Article 5* They would wpecify inter alia that the Commission ' could consult with regard to the measures to be proposed, in particular the Working Party on Electricity of the above mentioned Safety and Health ■

Commission which comprises{representatives of mining authorities, • testing stations, manufaturers and users. This Working Party could consult CE2TEL2C if necessary. ' ' . ' , ■ ' ; .

The certification documents referred to in Article 8(3) and Article 9 (?) (application, plans, descriptions, test reports) are confidential; .

-'copies are forwarded to the applicant on his request ana he may dispose of them as he sees fit. They are submitted to the Member States who have requested them under the provisions of Article 8(3) ana Article 9 (7)- The certificates of conformity ana the inspection certificates-are not confidential. - ' . .

• - - _ . * - ' f • - - ;

The application of Article 9 requires close collaboration between ' ■

the Community bodies which are approved to issue inspection certificates.

Article 11 requires that any electrical apparatus destined for free ..

trade in the Community should be identified by a distinctive Community mark.

‘The distinctive Community nfork signifies on the one hand that the type of apparatus has received either a certificate of conformity or an . inspection certificate, and on the other hand that the apparatus is' identical, to the type which has been certified.

The distinctive Community Mark comprises the symbol

being used to identify $he apparatus as suitable for gassy mines

The marking specified in the Harmonized Standards includes, in particular:

1. The symbol E Ex signifying that the electrical apparatus complies with one pr more of the types of protection standardised by CENEL2C and listed ih Article 4 (4); ' . • . ‘ ' ’

•> •

2. one or more of the symbols identifying the type of protection of electrical apparatus; .

Proposal for a

- COUNCIL DIRECTIVE .

on the approximation of the laws of the Member States concerning electrical equipment for use in potentially explosive atmospheres in mines susceptible ,

to fire-damp .. .

THE COUNCIL OF THE EUROPEAN COMMUNITIES,- - ■

Having regard to the Treaty establishing the European Economic Community, and in particular Article 100 thereof; - _ ,

Having regard to the proposal from the Commission; '

Having regard to the opinion of the European Parliament;

Having regard to the opinion of the Economic and Social Committee;

Whereas legislation in force in the Member States to ensure the safety of . electrical equipment for use in potentially explosive atmospheres in mines susceptible to fire-damp differs from one Member State to another, and whereas these differences are such as to constitute a barrier to trade; '

Whereas such differences may be eliminated by approximating the laws of the Member States in order to allow electrical equipment for use in potentially explosive atmospheres in mines susceptible to fire-damp and complying with harmonized standards to be put on the market throughout the Community;

Whereas provision'should also be made to allow electrical equipment using technical processes different from those of these harmonized standards to be put on the market, provided such equipment ensures a level of safety equivalent to that of equipment which conforms to the harmonized standards;

Whereas, however, compliance with harmonized standards or equivalence of safety levels to that of equipment which conforms to the harmonized standards should be examined by a body approved by the Member State concerned;

Whereas a positive result of such examination should be attested both by certificates and a mark recognized in all Member States; •

Whereas, in order to take account of technical progress, the technical specifications prescribed in the harmonized standards on electrical equipment for use in potentially explosive atmospheres in mines susceptible to fire-damp need to be adapted promptly; whereas, to facilitate the implementation of the measures necessary in this connection, a procedure should be laid down to ensure close cooperation between the Member States and the Commission through the Committee on the adaptation to technical progress of the Directives on the removal of technical barriers to intra-Community trade in electrical equipment in potentially explosive atmospheres in mines susceptible to firedamp; . ■ . . ^-

' - - l . . • . '

Whereas it is possible that electrical equipment for use in potentially explosive atmospheres in mines susceptible to fire-damp, although certified and marked for free movement, may represent a safety risk; whereas a . procedure should therefore be laid down to obviate this risk;

Whereas the mining legislation in different Member States applies also . to surface installations of mines susceptible to fire-damp, and whereas it is necessary to include in this Directive electrical equipment for use in such installations; whereas it is therefore necessary to derogate from/ Council Directive 76/117/EEC of 18 December 1975 on the approximation of .

' ' ' • r -

the laws of the Member States concerning electrical equipment for use in

1

potentially explosive atmospheres and from Council Directive 79/196/EEC of 6 February 1979 on the approximation of the laws of the Member States

concerning electrical equipment for use in potentially explosive atmospheres

- if it differs from harmonized standards because no provision was, made in such standards' for its design and manufacture, but the -examination has established that it offers a degree of safety at

Least equivalent to that of equipm:?nt which conforms to the

harmonized standards and this is attested by an inspection certificate issued under the conditions laid down in Article 9 and by the affixing of the mark provided for in Article '11. .

2. For the purposes of this Directive, use for its proper purpose means the

use of electrical equipment in parts where fire-damp is liable to form an explosive mixture with air, as provided for in the harmonized ^

standards of construction and as recorded in the certificate of \

conformity or inspection certificate. . ' ,
