1. A qualitative testing device comprising:
- an enclosure suitable for establishing an atmosphere around a test piece; and
an atmospheric controller operatively connected to the enclosure, the atmospheric controller operable to repeatedly change between atmospheres in the enclosure to alternately form and remove a deposition layer on the test piece, causing an oxidation layer to form on the test piece.

Abstract
An accelerated life testing device and method including an accelerated life testing method for a test piece within a test chamber, the method including: establishing a first atmosphere within the test chamber; changing the first atmosphere to a second atmosphere to form a deposition layer on the test piece; changing the second atmosphere to the first atmosphere to remove the deposition layer from the test piece; and repeating the changing the first atmosphere to the second atmosphere and the changing the second atmosphere to the first atmosphere to form an oxidation layer on the test piece.

16. A method of accelerated life testing, the method comprising:
-
forming a deposition layer on a test piece by changing a first atmosphere to a second atmosphere within a test chamber containing the test piece; removing the deposition layer from the test piece by changing the second atmosphere to another atmosphere; alternately forming and removing the deposition layer on the test piece by repeatedly changing between atmospheres; and forming an oxidation layer on the test piece from the alternately forming and removing the deposition layer on the test piece. - View Dependent Claims (17, 18, 19, 20)
