British and European Safety Standards – using Safety Window Film.
BS EN 12600 has now superseded BS 6206 as a European wide performance standard for impact Safety Window Film for glass.
Designed to be a more ‘modern’ test it provides much the same performance levels as BS6206 (see below).
Classifications within BS EN 12600 (in order of highest performance are:
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”.
Call 0844 800 9066 for more information.
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:
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 BS6206 Classifications:
|BS EN 12600 –||BS6206|
|1B1 –||Class A|
|2B2 –||Class B|
|3B3 –||Class C|
