The general routine procedure is described by the basic standard of the respective type of protection. This means that the basic standard of the respective type of protection must also be used as a basis when the quantities to be compared are selected, i.e. IEC 60079-0 for "Temperature Classification".

The maximal surface temperature is a decisive criterion for the testing and the assessment of the safety in explosion protection. This is why it the maximal surface temperature has been selected as the quantity to be compared for the program “Temperature Classification”.

In the program "Temperature Classification" the highest surface temperatures are determined for the Test Sample "TC" in accordance with IEC 60079-0. The test sample consists of a heating block made of steel with four heating cartridges as well as three different test plates, such as copper, plastic (polycarbonate) and glass. The test sample will be heated by the four heating cartridges with different electrical powers. To ensure comparability and homogeneity, all Test Samples "TC" are completely developed, prepared and provided by the coordinator.

The workload to perform this program is approximately 4 working days.
