About NATG

The DIN Standards Committee Technical Fundamentals (NATG) is in its 5 sections responsible for the following standardization areas:

  • fundamentals for physics and mathematics;
  • screw threads for general use;
  • geometrical product specifications (GPS), i.e. tolerancing and verification of dimensions, form, orientation and roughness;
  • measurement of pressure, flow and temperature;
  • technical product documentation and technical drawings.

How is NATG composed?
