For the program “Explosion Pressure” the general routine procedure is described by the standard “Explosive atmospheres - Part 1: Equipment protection by flameproof enclosures "d"” - IEC 60079-1, Edition 7.0. An essential characteristic for the testing and assessment of the explosion protection is the ability of the enclosure to withstand pressure (clause 15.2.). This is of decisive importance for the design and construction of “d” products. Therefore, the explosion pressure (reference pressure) has been selected as the quantity to be compared in the program “Explosion Pressure - Test Round 2017”.

The Test Sample “EP” consists of two cylindrical compartments of different lengths as well as an orifice. Additionally, two blank flanges are included, each equipped with five test holes of different thread forms.

The simple design and homogeneity tests guarantee homogeneity and stability during the whole test round. In addition, the selected design of the test sample offers convenient manufacturing, preparation and transport possibilities. To ensure comparability and homogeneity, all Test Samples “EP” are completely selected, prepared and provided by the coordinator.

Detailed information and specifications regarding the test sample are described in the “Procedure Instruction of Program Explosion Pressure - Test Round 2017” which will be published at a later date.
