G01N 27/00 - Definition
This main group covers:
Investigating non-electric or non-magnetic properties of materials by using electric or magnetic methods.
Investigating by electrochemical means, e.g.:
Instruments, e.g. hygrometers, for measuring non-electric or non-magnetic properties.
Relationship between large subject matter areas
Measuring or investigating electric or magnetic properties of materials is classified in G01R, as opposed to investigatingmaterials by electric or magnetic means, which is classified in this group.
