ISO 9693:2019 Dentistry – Compatibility testing for metal-ceramic and ceramic-ceramic systems.
This document lays down rules for the representation of modular sizes, lines and grids on construction drawings. The basic module M is 100 mm (see Iso 1006).
Generally, modular sizes are for use on design drawings, but can also be added to production drawings for manufacturing, orientation and location.

4 General
Drawings with modular sizes shall be executed in accordance with ISO 128-1 and Iso 129-1. If necessary, the drawings should have a note indicating that modular sizes are being used.
5 Designations of modular sizes
Drawings with sizes indicated in modules (instead of in millimetres or metres) should have a clear note explaining that this is the case.
4 Requirements
4.1 Biocompatibility
Specific qualitative and quantitative test methods for demonstrating freedom from unacceptable biological risks are not included in this document, but it is recommended that, for the assessment of such biological risks, reference be made to ISO 10993-1 and ISO 7405.
4.2 Physical properties
4.2.1 General
The individual component materials shall fulfil the requirements of ISO 6872 for ceramics or ISO 22674 for metallic materials. The materials shall also be in accordance with the requirements of 4.2.2 to 4.2.4 where applicable.
In particular, the elastic modulus of the substrate material shall be determined in order to interpret the measurements in the de-bonding test.
4.2.2 Thermal expansion
The coefficients of thermal expansion of the substructure ceramic and the veneering ceramic shall be determined according to ISO 6872.
The coefficients of thermal expansion of the metallic substructure material shall be determined according to ISO 22674.
