STD-TE 69 ENHANCED LOAD SCANNER

Описание

With the STD-TE 69 Load Scanner geometry, the samples are indexed and the load applied by three independently controlled, but synchronised motion, actuators. Two elongated test specimens, preferably bars or rods, are used. The orientation of the test specimens and their relative sliding motion during testing is arranged in such a way that the contact spot moves along a contact path on each specimen; each spot along this path on one specimen will only make contact with one spot on the other specimen, and vice-verse. The contact spot is the area over which the contact load is distributed.

Standard Load Scanner Applications

A single pass experiment resembles the test procedure often used in scratch testing of coated specimens. For coatings evaluation, it is normal to have one specimen coated and select the material from the practical application, for the counter specimen.

Reciprocating sliding tests, with stroke-wise load variation, can be used to produce conditions ranging from mild wear to scuffing, at different positions on a single pair of specimens.
