G01N 31/00 - Definition
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.)
References relevant to classification in this main group
This main group does not cover:
Testing the effectiveness or completeness of sterilisation procedures without using enzymes or micro-organisms (involving enzymes or micro-organisms C12MC12Q) | A61L 2/28 |
Apparatus for enzymology or microbiology | C12M |
Measuring or testing processes, other than immunoassay (which is covered by G01N 33/53), involving enzymes or micro-organisms | C12Q |
Attention is drawn to the following places, which may be of interest for search:
Sampling; preparing specimens for investigation | G01N 1/00 |
Systems in which material is subjected to a chemical reaction, the progress or the result of the reaction being optically investigated | G01N 21/75-G01N 21/83 |
Investigating or analysing biological material by chemical analysis | G01N 33/50 |
Automatic analysis; handling materials therefor | G01N 35/00 |
Combinatorial chemistry; Libraries | C40B |
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.
