Security is an important consideration when buying windows or doors for your home. The level of security provided by a window or door will depend upon the design, quality of manufacture, the hardware specified and the type of glazing used.
There are various national and European standards for burglary prevention. Among other things, they regulate requirements, test methods and classification for the determination the level of resistance. The standard defines resistance classes, resistance times (the time a product can withstand a burglary), offender types.
Product Assessment Specification (PAS 24), published by the BSI, is a standard used to assess the enhanced security performance of external windows and doors against the effects of an opportunistic burglar. It involves a set of tests which simulate attacks most often associated with opportunistic burglary.
PAS 24 is a ‘minimum standard’ and doesn’t have ‘grades’ or ‘performance’ scores, so windows and doors that are tested to PAS 24 standard either pass or fail.
PAS 24 applies to any windows and doors with the following methods of opening:
Approved Document Q specifies PAS 24 as the required test standard for new dwellings. It is intended to make sure that any windows and doors that could provide access into your property should conform to a certain level of security against casual intruders. A new revised version of PAS 24 (PAS 24:2016) was launched in March 2016, so PAS 24:2012 was withdrawn by the BSI (British Standard Institute).
European Standard EN 1627
European Standard EN 1627 is one of a series standards regarding burglar resistance for doorsets, windows, curtain walling, grilles and shutters. The standards in this series are:
- Resistance to static pressure (EN 1628)
- Resistance to dynamic pressure (EN 1629)
- Resistance to manual burglary attempts (EN 1630)
Various classification and the requirements are described in the European EN 1627 standard. There are a total of six classifications, also called resistance classes. These are classified as followed:
|Resistance Class||Burglary Type||Use||Test Duration|
|RC1||Basic protection against burglary by the use of physical force||Premises without increased risk of burglary||-|
|RC2||Occasional burglar uses basic burglary tools||Increased protection for normal housing security||3-15 mins|
|RC3||Experienced burglar additionally uses electric saws and power drilling tools||High level of security for the premises in view of increased risk of burglary||5-20 mins|
|RC4||Experienced burglar additionally uses power cutting and heavy duty drilling tools||Extra high level of housing protection in view of high risk of burglary||10-30 mins|
|RC5||Experienced burglar additionally uses power cutting and heavy duty drilling tools||Extremely high protection for military and industrial premises.||15-40 mins|
|RC6||Experienced burglar additionally uses power cutting and heavy duty drilling tools||Extremely high protection for military bunkers, etc||20-50 mins|
