and European Safety Standards - using safety window
BS EN 12600 has now superseded BS 6206 as a European wide performance standard
for impact safety glass.
Designed to be a more 'modern' test it provides much the same performance levels
as BS6206 (see below).
The new classifications within BS EN 12600 (in order of hihest performance are0:
In order to be classified as an impact safe material glass is subjected to this
Safety Standard Test. This test defines the level at
which glass will "break safe".
The test incorporates the dropping of a weight from three heights onto a standard
sized pane of glass.
The point at which the glass breaks forms part of it's classification.
The standard defines three drop heights:
Class 3, 190mm drop height,
is equivalent to an adult pushing hard against the
glass or a child running into it.
Class 2, 450mm drop height, is equivalent to rather more than an adult walking
into a glass door, but less than a determined attempt
to force a way through by running at it.
Class 1, 1200mm drop height, is for testing glass for critical applications.
Type B breakage is characterised by the fragments being held together, this is
the typical breakage mode for glass with a safety film
applied or laminated glass.
IMPORTANTLY materials that are classified as safety material meeting the performance
criteria of BSEN 12 600 MUST carry an identifiable
mark showing the level of safety achieved during test.
In basic principles the table below shows a comparison between BS EN 12600 and
