Thermoplastics extruded profiles; general tolerances of size, form and orientation (Foreign Standard)
This standard applies to general tolerances for dimensions and tolerances of form and position for extruded profiles of plastics materials. If smaller tolerances are required or higher tolerances are permissible and more economical, a detailed specification is necessary. The standard contains 3 tolerances series with different grades of accuracy for the lateral or longitudinal axis of the extruded profile.
