From July 2003, explosion protection regulations will be based on ATEX100a. European Union directive 94/9/EC is based on article 100a of the treaty establishing the EC. ATEX 100a is the working title and is derived from “atmosphères explosible”. Implementation into national law was via the 11th regulation on the equipment safety law of the explosion protection regulation (ExVO). The transitional period finishes on 30.06.2003. From this date, only equipment with ATEX approval must be produced and sold for use in areas of explosive hazard within the EU. Switzerland and some eastern European countries have also implemented ATEX100a within their national legislation.

For areas of explosive hazard of zone 2, it is assumed that no hazards from explosive atmospheres such as gases, vapours or mist are present. Any such occurrences are rare and short-term. The Beckhoff Bus Terminals should be classified as category 3 devices. During normal operation, they meet the safety requirements for zone 2. The user should follow the special conditions for the safe use of the Bus Terminal system components that are certified for areas of explosive hazard.
