In order to evaluate and classify the quality of materials we have introduced the dimensional tolerances.
By means of this classification we can establish the upper and lower limits according to the standard in force for each material.
A material is covered by a standard as long as the limits marked by the standard are fulfilled.
What standards are applicable to our materials?
A standard contains technical specifications based on results emerged from the experience and technological development. Standards are voluntary in application and they must be approved by a recognized Standardization Organism. Standards ensure a high level of quality and safety.
Our materials are covered by the following STANDARDS:
