This part of VDE 0165 contains the specific requirements for the design, selection, erection and initial inspection of electrical installations in, or associated with, explosive atmospheres. These requirements are in addition to the requirements of the standards of the VDE 100 series for electrical installations in non-hazardous areas. This standard applies to all electrical equipment including fixed, portable, transportable and personal, and temporary installations. Where the equipment is required to meet other environmental conditions, for example, protection against ingress of water and resistance to corrosion, additional protection requirements may be necessary. The requirements of this standard apply only to the use of equipment under standard atmospheric conditions as defined in DIN EN 60079-0 (VDE 0170-1). For other conditions, additional precautions may be necessary, and the equipment shall be certified for these other conditions. For example, most flammable materials and many materials which are normally regarded as non-flammable might burn vigorously under conditions of oxygen enrichment. The responsible body is DKE/K 235 "Errichten elektrischer Anlagen in explosionsgefährdeten Bereichen" ("Installation of electrical equipment in hazardous areas") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
