Chromatics Resist now classified as 1B1
Chromatics Resist now classified as 1B1
The photograph clearly shows that during the Wintech test it was possible for the rig operatives to simply remove the single pane in its entirety, despite the severity of the impact.
A recent Wintech test report (1) confirms that Chromatics is now classified as 1B1, having met the requirements of BS EN 12600 by fully passing the pendulum impact test for single flat panes of glass for use in buildings. 1B1 is yet another exceptional performance standard achieved by this unique product, made possible by the extraordinarily resilient qualities it acquires by bonding together, at a molecular level, float glass, colour layer and metal, transforming them into a laminate that, when fractured after repeated impact, remains safely intact.
The test itself involves a 50kg pendulum weight on a steel wire, released against the panel using incrementally increasing angles of release. Classes are 1B1, 2B2 and 3B3, where 1B1 is the best performance and simulates the impact of a 12-year-old boy hitting the panel. In addition to Chromatics Resist the standard Chromatics safety glass meets the requirement 3B3.
Both standard Chromatics and Chromatics Resist can be produced in almost any RAL colour or with a printed image and can be cut to size as required.
Test Report: Certificate No. 09/2414/09662
Wintech Engineering Limited, the world’s first UKAS accredited laboratory to BS EN 12600, offers a wide range of impact testing services at its facilities in Telford, Shropshire and on site. Its partnership with the Glass and Glazing Federation (GGF) has led them to become an accomplished glass impact test laboratory.
Architectural Specification – Chromatics Resist
Chromatics Resist safety glass, compliant with BS EN 12600 Class 1(B)1, comprises 6mm float glass, having an opaque, coloured, organic coating, free from heavy metal and volatile organic content in RAL... applied to the second surface of the glass. The second surface will also have a reinforcing material encapsulated by an aluminium foil vapour barrier. (When incorporated in an IGU the foiled surface will be surface 4.) The glass, colour layer, reinforcing material and foil will be bonded together at a molecular level, resulting in a shatterproof panel which will remain glazed even if broken. The opaque, coloured coating will be free from pin-holes, will be fully reproducible, will not fade or discolour, will be resistant to scratching, will remain stable under extreme weather conditions and will be resistant to UV degredation. The substrate will be annealed float glass and panels will be available from stock.
