LA QUESTION :<\/strong><\/p>\n

Les \u00e9quipements contenant des atmosph\u00e8res potentiellement explosives et install\u00e9s dans des zones s\u00fbres rel\u00e8vent-ils de la directive ATEX 2014\/34\/UE (\u00e9galement appel\u00e9e ATEX 114) ?<\/p>\n

CONSID\u00c9RATIONS :<\/strong><\/p>\n

Prenons l’exemple d’un m\u00e9langeur qui contient une atmosph\u00e8re potentiellement explosive, mais qui est compl\u00e8tement ferm\u00e9 lorsqu’il fonctionne. Il est install\u00e9 dans une zone non class\u00e9e alors que le fabricant, lors de l’\u00e9valuation des risques, a d\u00e9fini une zone 0 \u00e0 l’int\u00e9rieur. Doit-il \u00eatre marqu\u00e9 CE de cat\u00e9gorie 1<\/strong> conform\u00e9ment \u00e0 la directive sur les produits ATEX, ce qui implique l’intervention d’un organisme notifi\u00e9 avant sa mise sur le march\u00e9 ? La r\u00e9ponse est non.<\/strong><\/p>\n

La directive ATEX s’applique aux \u00e9quipements install\u00e9s dans des zones class\u00e9es ATEX, c’est-\u00e0-dire dans des zones class\u00e9es avant l’installation de la machine. Voici ce que dit la directive :<\/p>\n

[2014\/35\/EU] Article 1 – Champ d’application<\/strong><\/em>
\n1. La pr\u00e9sente directive s’applique aux produits suivants, ci-apr\u00e8s d\u00e9nomm\u00e9s \u00ab\u00a0produits\u00a0\u00bb :<\/em>
\n(a) les appareils et les syst\u00e8mes de protection destin\u00e9s \u00e0 \u00eatre utilis\u00e9s en atmosph\u00e8res explosibles ;<\/em><\/p><\/blockquote>\n

Et ce que dit le guide officiel :<\/p>\n

[2014\/35\/UE] \u00a7 34 Lieu d’utilisation pr\u00e9vu<\/strong><\/em><\/p>\n

[…] Il est important de souligner dans ce contexte comment les machines ayant une atmosph\u00e8re potentiellement explosive \u00e0 l’int\u00e9rieur dans les conditions de fonctionnement, mais n’ayant pas d’interface avec des atmosph\u00e8res potentiellement explosives externes, doivent \u00eatre consid\u00e9r\u00e9es. Ces machines, en tant que partie int\u00e9grante, ne rel\u00e8vent pas du champ d’application de la directive ATEX 2014\/34\/UE.<\/em><\/p><\/blockquote>\n

La m\u00eame approche s’applique \u00e0 la directive \u00ab\u00a0Machines\u00a0\u00bb. Ci-apr\u00e8s le langage de son guide officiel :<\/p>\n

[2006\/42\/CE] ANNEXE I : Exigences essentielles de sant\u00e9 et de s\u00e9curit\u00e9 relatives \u00e0 la conception et \u00e0 la construction des machines<\/strong><\/em><\/p>\n

1.5.7 Explosion<\/strong>. La machine doit \u00eatre con\u00e7ue et construite de mani\u00e8re \u00e0 \u00e9viter tout risque d’explosion du fait de la machine elle-m\u00eame ou du fait des gaz, liquides, poussi\u00e8res, vapeurs ou autres substances produites ou utilis\u00e9es par la machine […].<\/em><\/p><\/blockquote>\n

Le guide officiel de la directive \u00ab\u00a0Machines\u00a0\u00bb contient le texte suivant :<\/p>\n

[Guide 2006\/42\/CE] \u00a7228 Explosion<\/strong><\/em><\/p>\n

[\u2026]Bien que la directive ATEX ne soit pas applicable en tant que telle aux risques d’explosion g\u00e9n\u00e9r\u00e9s \u00e0 l’int\u00e9rieur de la machine elle-m\u00eame, […]<\/em><\/p><\/blockquote>\n

CONCLUSION :<\/strong><\/p>\n

Lorsque l\u2019\u00e9quipement, l\u2019ensemble ou, plus g\u00e9n\u00e9ralement, la machine contient une atmosph\u00e8re potentiellement explosive, une \u00e9valuation des risques doit \u00eatre r\u00e9alis\u00e9e conform\u00e9ment \u00e0 la norme EN 1127-1 ainsi qu\u2019\u00e0 l\u2019ensemble des normes harmonis\u00e9es applicables \u00e0 la directive ATEX \u00ab Produits \u00bb.<\/p>\n

Si des \u00e9quipements, tels que des instruments, sont install\u00e9s \u00e0 l\u2019int\u00e9rieur de la machine, ils doivent \u00eatre conformes \u00e0 la directive ATEX 2014\/34\/UE et porter le marquage CE correspondant. En revanche, la machine elle-m\u00eame, lorsqu\u2019elle est install\u00e9e dans une zone non class\u00e9e, n\u2019est pas soumise \u00e0 la directive ATEX \u00ab Produits \u00bb.\u00a0Une exception<\/strong> existe toutefois lorsque l\u2019atmosph\u00e8re interne de la machine est susceptible de g\u00e9n\u00e9rer une zone ATEX \u00e0 l\u2019ext\u00e9rieur, par exemple dans le cas d\u2019une tuyauterie transportant un gaz explosif (comme le m\u00e9thane) sous haute pression.<\/p>\n

Cependant, en r\u00e8gle g\u00e9n\u00e9rale, l’int\u00e9rieur n’a pas besoin d’\u00eatre marqu\u00e9 CE conform\u00e9ment \u00e0 la directive ATEX.<\/strong><\/p>\n<\/div> <\/div>\n \n \n
