The technical specification involves a variation of tests carried out to one of six resistance classes, which equate to different lengths of attack and types of tools.
BR1 and BR2 address the level of attack normally associated with casual or opportunist burglars, being loosely based on low risk domestic properties.
BR3 and BR4 address the level of attack associated with more practiced burglars prepared to make noise and take risks; these tests are based on medium risk commercial properties.
BR5 and BR6 cover professional type burglars with planned attacks using power tools and no regard to noise levels; these classes are designed to address high risk, high security properties.
Although STS202 Issue 3 : 2011 does not specifically refer to rooflights or roof windows, there is no specific requirement to test vertically so the specification could still be applied if testing glass rooflights.
Windows satisfying this standard meet the security requirements outlined in Approved Document Q – Security in Dwellings (2015) where it refers to Secured by Design’s New Homes 2014 document. Approved Document Q addresses standards required for doors and windows to resist physical attack by a casual or opportunist burglar.
Approved Document Q does not apply to work started before 1st October 2015, work subject to a building notice or for planning submitted before that date provided work commences before 1st October 2016.
To find out more about the range of standards that meet Approved Document Q guidelines, read our post ‘Part Q and security testing for glass rooflights’.
Where a product manufacturer has successfully passed relevant Part Q security testing to an approved standard, their product can be marked with a ‘Secured by Design’ logo; Secured by Design is a scheme supported by the police in order to lower the current trends in crime.
