NOTES

  • In this subclass, the following terms are used with the meanings indicated :
    • "investigating" means testing or determining;
    • "materials" includes solid, liquid or gaseous media, e.g. the atmosphere.
  • Attention is drawn to the Notes following the title of class G01.
  • Investigating the properties of materials, specially adapted for use in processes covered by subclass B23K, is classified in group B23K 31/12.
WARNING

  • In this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme.
