EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60068-2-42 testing. It provides accelerated tools to evaluate the corrosive effects of sulfur dioxide-polluted atmospheres on contacts and connections.
This test:
Purpose of this test:
The test chamber and its auxiliary parts should be made of materials that do not react with or absorb sulfur dioxide and do not affect the corrosive effects of the test atmosphere. The air and sulfur dioxide mixture will enter and exit the chamber through pipes of sufficiently large diameter such that the total flow through the chamber is at least three but not more than five atmospheric changes per hour. Exhaust gas from the chamber should not be allowed to enter the laboratory.
Adequate precautions will be taken to prevent the contacts from deteriorating. The method used to measure the contact resistance should be the same as that used for the initial measurement.
In general, the contact resistances of samples exposed to contacts in the assembled state should be measured before mating. Samples exposed to contacts in the unpaired state should be matched once and then the contact resistance measured.
