Abstract

Abstract Electrochemical measures and treatments and diffractometric analysis of given areas of a same surface of a metal test strip are allowed by a device by which it is possible to obtain several tests in a relatively short period of time as compared to the time needed by conventional methods, being further sure that such different tests concern a single surface of a same test strip. Therefore, the material on which the treatments are performed not only is of the same composition, but also offers to the various successive tests a surface which was subject to the same cleaning process. The relevant metal test strip must thus assume a particular shape in order to be used with the device.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 24 words
Test apparatus according to claim 1, in which said means for supplying a flow of materials comprises two conduit means extending into said cavity.
Claim 2
Dependent Claim 43 words
Test apparatus according to claim 1, in which said means to hold a testpiece comprises a rotatable pin, means mounting the pin for axial reciprocal movement, means biasing the pin into engagement with the testpiece when said testpiece is mounted on said apparatus.
Claim 3
Dependent Claim 17 words
