An explanatory publication describes how pneumatic systems are affected by the new ATEX 95 directive on explosive atmospheres, which replaced ATEX 100a
An explanatory publication has been compiled by Hoerbiger-Origa on how pneumatic systems are affected by the new ATEX 95 directive on explosive atmospheres, which replaced ATEX 100a in July 2003. Under the new regime responsibility for safety of newly built plant with potentially explosive atmospheres no longer lies only with the manufacturer of explosion proof equipment, but also with the builders and operators of the plant. The use of electrical equipment in explosive environments has long been covered by safety laws.

ATEX 95 extends the legislative requirements to also cover non-electrical equipment such as pneumatic cylinders and valves, fittings and tubing.

Hoerbiger-Origa's authors provide an overview of the classification of machinery types and environments types as defined in ATEX 95, and of the markings used to signify levels of safety.

They provided a good introduction to the subject, creating a good basis for further reading and/or investigation in specialist areas.

The publication concludes with a review of Hoerbiger-Origa products and their ATEX classification.
