BSI changes screen repair standard

Standards Institution BSI has made changes to the automotive glazing repair standards.

Ever-changing ADAS and head-up display (HUD) technology prompted the changes. According to the new standard, known as BS AU 242b, repairs are permitted in ‘Zone A’ (400mm wide area in front of the driver, centred on the steering wheel with the top arc of the driver’s windscreen wiper) for damage that’s within a circle 20mm in diameter. For the rest of the windscreen, repairs are permitted for damage that’s within a circle 40mm in diameter. Replacements are required in windscreen areas supported by any aspect of ADAS or HUD technology.

Tony Green, Head of Technical Training at Auto Windscreens was recently part of the panel of industry experts involved in helping to oversee the introduction of the new standards (BSau242b), and the company will be adopting them from this month. He explained: “With the introduction of ADAS technology and the popularity of panoramic windscreens in MPVs and 4x4s, the changes in vehicles on our roads in the last 24 years are quite literally through the roof”.

“Windscreens have increased by around 33% in height since 1998 – a Fiesta windscreen is now 28% bigger than it was back then, and the largest production windscreen, from the Tesla Model X, is around 55% larger than the size of an old Fiesta’s. The industry now is very different to the one I joined, and with vehicle technology changing all the time, it’s important the repair standards reflect this.”
