G01N 3/00 - Definition
This main group covers:
Stressing of materials not only below but also beyond the elastic limit, e.g. until breaking occurs.
Application of mechanical stress:
Testing apparatus and sample holders used in such investigations.
Relationship between large subject matter areas
Testing or determining the elasticity, or vibration-testing, or shock-testing of structures, e.g. apparatus, machine parts etc, is classified in G01M, as opposed to investigating, i.e. testing or determining, the strength properties of materialsamples, which is classified in this group.
Attention is drawn to the following places, which may be of interest for search:
Sampling; preparing specimens for investigation | G01N 1/00 |
Investigating or analysing surface structures in atomic ranges using scanning-probe techniques, e.g. atomic force microscopy (ATM) | G01Q 10/00-G01Q 90/00 |
