G01N 31/00 - Definition fr

Definition statement

This main group covers:

Investigating non-biological materials by the use of:

Investigating the properties of materials specially adapted for use in processes covered by subclass B23K (namely: soldering or unsoldering; welding; cladding or plating by soldering or welding; cutting by applying heat locally, e.g. flame cutting; working by laser beam) which is classified in the group G01N 31/12 (investigating using combustion). (See note (3) after the title of G01N.)

Special rules of classification

The observation of the progress of the reactions as covered by groups G01N 31/02-G01N 31/22 by any of the methods specified in groups G01N 3/00-G01N 29/00, if this observation is of major importance, is classified in the relevant group covering the method.
