La derni\u00e8re \u00e9dition de la norme I<\/strong>EC60079-10-1:\u00a0<\/strong> Explosive atmospheres \u2013 Part 10-1: Classification of areas \u2013 Explosive gas atmospheres\u00a0<\/em>a \u00e9t\u00e9 publi\u00e9e en\u00a02020.<\/strong><\/p>\n

Cette \u00e9dition est entr\u00e9e en vigueur en France en fevrier 2021. NF EN IEC60079-10-1 :<\/strong> Atmosph\u00e8res explosives – Partie 10-1 : classification des emplacements – Atmosph\u00e8res explosives gazeuses<\/em><\/p>\n

Voici les principaux changements par rapport \u00e0 l’\u00e9dition pr\u00e9c\u00e9dente :<\/p>\n

– L’exclusion du champ d’application pour les gaz combustibles \u00e0 basse pression<\/strong> n’est plus pr\u00e9sente dans l’art.1. Cet aspect est maintenant rapport\u00e9 dans l’art. 5.3.2. Fondamentalement, rien n’a chang\u00e9.<\/p>\n

– La d\u00e9finition de \u00ab\u00a0NE<\/strong>\u00a0\u00bb est plus complexe et comprend :<\/p>\n

– Des limites pour la pression d’explosion<\/p>\n

– Limitations de la chaleur \u00e9mise lors de l’explosion<\/p>\n

– Pour les gaz dont la pression est sup\u00e9rieure \u00e0 10 bar, une \u00e9valuation des risques est requise.<\/p>\n

– Pour les gaz dont la pression est sup\u00e9rieure \u00e0 20 bar, la NE ne doit pas \u00eatre appliqu\u00e9e \u00e0 moins qu’une \u00e9valuation d\u00e9taill\u00e9e des risques ne le permette.<\/p>\n

– La vitesse minimale<\/strong> \u00e0 prendre en compte pour les environnements int\u00e9rieurs (fix\u00e9e par la 2e \u00e9d. \u00e0 0,05 m\/s) a \u00e9t\u00e9 supprim\u00e9e.<\/p>\n

– Le facteur de s\u00e9curit\u00e9 k<\/strong> n’est plus pr\u00e9sent dans le calcul de la caract\u00e9ristique de lib\u00e9ration utilis\u00e9e dans la figure D.1 ; la norme permet donc une approche moins conservatrice.<\/p>\n

– Les formules C.2 \u00e0 C.6 pour le calcul des d\u00e9bits d’air<\/strong> ont \u00e9t\u00e9 modifi\u00e9es.<\/p>\n

– Les distances minimales de danger<\/strong> indiqu\u00e9es dans le nomogramme D.1 sont fix\u00e9es \u00e0 1 m.<\/strong><\/p>\n

– L’\u00e9quation du taux d’\u00e9vaporation d’une piscine<\/strong> a \u00e9t\u00e9 corrig\u00e9e.<\/p>\n

– La d\u00e9termination des distances de danger<\/strong> n’est plus possible en utilisant le nomogramme pour les environnements int\u00e9rieurs \u00e0 faible et moyenne dilution.<\/p>\n<\/div> <\/div>\n \n \n
