Test chamber for testing resistance of electrical equipment to dampness, especially in salt-laden atmosphere has flow guiding surface for guiding air from humidification device to ceiling of chamber

摘要

The chamber includes a test region with a test-piece holder, and a humidifying region with an air humidification device (20). The air outlet from the latter sends the damp air upwards. At least one flow guiding surface (17) is provided for guiding the damp air form the air humidification device to the upper ceiling of the chamber above the test region. An Independent claim is included for a method of testing the resistance of test-pieces to a salt-laden atmosphere.
