IEC TS 60079-32-1:2013 fournit les recommandations relatives au matériel, au produit et aux propriétés de processus nécessaires pour éviter l'inflammation et les dangers de chocs électrostatiques liés à l'électricité statique, ainsi que les exigences de fonctionnement nécessaires pour garantir l'utilisation en toute sécurité du matériel, du produit ou du processus. Elle peut être utilisée dans le cadre d'une appréciation du risque des dangers électrostatiques ou de l'élaboration de normes de famille de produits ou de normes de produits spécifiques concernant des machines ou des équipements électriques ou non électriques. L'objet du présent document est de fournir des recommandations normalisées pour le contrôle de l'électricité statique, telles que la mise à la terre des conducteurs, la réduction de l'électrisation et la restriction des zones électrisables des isolateurs. Dans certains cas, l'électricité statique fait partie intégrante d'un processus (revêtement électrostatique, par exemple), mais elle s'accompagne souvent d'un effet secondaire gênant, ce sur quoi portent les présentes recommandations. Si les recommandations normalisées indiquées dans le présent document sont respectées, le risque de décharges électrostatiques dangereuses attendues dans une atmosphère explosive peut être à un niveau bas acceptable.
