The accuracy of the mixtures is assured by comparing sample mixtures with the use of a gas chromatograph. Via Mazzini 75, Rezzato C. ATEX tests sector. It also carries out tests according to the IEC series of standards for the scheme IECEx The chamber has an internal volume of about 4 m3 and can accommodate devices with dimensions up to x x mm with the possibility of powering the equipment under test with a voltage up to V in three-phase and a maximum current of A.

Under ATEX and IECEx, an explosive atmosphere is defined as a mixture of dangerous substances with air, under atmospheric conditions, in the form of gases, vapours, mist or dust in which, after ignition has occurred, combustion spreads to the entire unburned mixture. Atmospheric conditions are commonly referred to as ambient temperatures and pressures.
Measures include using only Ex approved equipment. In the EU, this is a legal obligation. Both however, provide an accepted means of proving compliance with IEC standards. It requires that where the risk assessments identify workplaces as likely to be hazardous areas or explosive atmospheres, that the areas are classified into zones: Zone 0 — where an explosive atmosphere is present continuously or for long periods; Zone 1 — where an explosive atmosphere is likely during normal operations; Zone 2 — where an explosive atmosphere is unlikely, but where it does occur, that it will only exist for a short period.
