Program "Tests of Enclosures" (Test Round 2019)

For the program "Tests of Enclosures ("TE") - Test Round 2019" the general routine procedure is described by the standard "Explosive atmospheres - Part 0: Equipment – General requirements" - IEC 60079-0, Edition 7.0 and "Degrees of protection provided by enclosures (IP Code)" - IEC 60529, Edition 2.2.

Enclosures used in the field of explosion protection must meet certain criteria and be subjected to certain tests. These tests are defined in the standards mentioned above. Essential characteristics for testing and assessing explosion protection are tests on enclosures for resistance to impact and for protection of the equipment inside the enclosure against ingress of solid foreign objects (dust) and water. Therefore, compliance with the degree of protection (IP) has been selected as the characteristic of interest which is to be compared in the program “Tests of Enclosures - Test Round 2019”. Next to this characteristic of interest, other aspects like "how to perform the thermal endurance test" and the comparison of test conditions during the performance of tests will be analyzed. Due to the better practicability of the program, a selection of enclosure tests is carried out which are partly shortened or modified.

The Test Sample "TE" consists of 12 prepared empty enclosures with the outer-dimensions 170 mm x 170 mm x 91 mm (H x W x D). 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 "TE" are completely produced, prepared and provided by the coordinator in cooperation with a manufacturer for terminal boxes.

The workload to perform this program is approximately 3 working days (separated by additional waiting periods due to thermal endurance tests and IP testing).
