Breviary Technical Ceramics






10.3 General Tolerances for Dimensions and Shapes

Technical ceramics make use of different standards. DIN 40 680 specifies dimensional and shape tolerances for components that are to be used "as fired", i.e. without any additional processing after firing. The precision required depends on the manufacturing technique and the material.

DIN ISO 2768 and DIN ISO 1101 specify tolerances for components that will require additional hard machining, such as grinding, after firing in order to achieve the precision necessary for machine construction.
