Product or simple product according to ATEX?

In order to answer this question in a specific case, it is worth taking a look at the guideline of Directive 2014/34/EU. The analysis of the “own potential ignition sources” is crucial for the classification. 

Products for use in hazardous areas  

Electrical equipment always and mechanical equipment very often have their own potential ignition source, e. g. hot surface. Potential means that the energy of the ignition source is sufficient to ignite an explosive atmosphere. In accordance with Directive 2014/34/EU, Ex equipment (products) require the CE marking and proof of conformity depending on the category, the protective measures as well as the testing and certification. The manufacturer must ensure this. The focus is on safe use in hazardous areas. 

“Simple products” for use in hazardous areas  

With hand-operated devices (pumps, valves) that are operated with human power, the slow movement does not create such a hot surface. Therefore, these simple products do not fall within the scope of Directive 2014/34/EU. The manufacturer must still check his device with regard to “own potential ignition sources” and decide whether the ATEX directive applies. The simple products can be used in areas with explosive atmospheres without any category, special protection and compliance measures. However, for safe use, the user must consider and avoid the remaining ignition hazards, e. g. from an electrostatic ignition source.
