The materials covered in the following tables
find widely different applications. For this reason some of
the data are not given. As a general rule, electrical
and mechanical applications can be differentiated.
Those materials classified according to DIN EN 60
672-1 are given minimum specifictions for application
in electrical and electronic engineering,
but are also applied elsewhere. Flexural strength for technical
ceramic materials are determined according to DIN EN 60 672-2
(see p. 263 ff.).

Due to the wide range of property values quoted by manufacturers,
the values given in the following tables are indicative or
minimum specification values. The actual values are often
much better! It is therefore advisable to request reliable
values from the manufacturers.
The values for bending strength, ,
determined by the 3-point bending test, are about 30 % greater
than those obtained from the 4-point bending test!
