Atex Brochure - 14694 Which certificates are required?

A Declaration of Conformity must be provided by the manufacturer for each product. TheDeclaration of Conformity explains how the manufacturer fulfils all the relevant safety requirements. The CE mark is subsequently attached to the product.For electrical equipment in Category 1 and 2, an EC Type Test Certificate issued by a notified bodyis required. One of the notified bodies is the PTB (Physikalisch Technische Bundesanstalt). For non electrical equipment an EC Type Examination Certificate is only required for Category1.These certificates are also obligatory for non-electrical equipment. However, if the risk analysisof explosion hazards show that no potential sources of ignition exist, the item does not fall under the ATEX directive in which case a Declaration of Conformity and Ex marking is not required. This may apply to products used in purely pneumatic systems, i.e. for valves, service units, sound absorbers or manometers.
