British Standards Industry
The British Standards Institute is the Authority responsible for setting manufacturing standards for product safety and quality. These are strict standards that products should reach or surpass, in order to be regarded as both safe and manufactured to a consistently high standard.
Companies wanting to display the respected British Standards Institutes Kite Mark, pay to have their product(s) tested against British and International Standards. When a company is registered with the BSI, its manufacturing processes and products are checked frequently, to ensure that the high standards set by the BSI are maintained.
There are many standards for windows and doors, covering material and performance requirements:
BS 7412 specifies requirements for the design, fabrication and performance of windows and glazed doorsets made from PVC-U extruded hollow profiles. It applies to windows and doorsets manufactured from PVC-U hollow profiles incorporating fusion welded corner joints.
BS 7412 applies to windows and doors fabricated into frames in a factory, to be installed vertically (within 15°) into the external face of buildings, as single or multi-light units, in coupled assemblies when appropriate
BS 7412/PAS 24
BS 7412/PAS 24 It is also the British Standard product specification for the fabrication of PVCu Windows. Security and manufacturing process tests are included, as well as subjecting the windows to high velocity air and water jets to test weather proofing.
BS 7412/PAS 24 is the enhanced security performance requirements for door assemblies. They are subjected to manual intervention, mechanical loading and hard and soft body impact tests. All approved doors include all the Secured by Design standards.
This British Standard specifies performance requirements and a test method in respect of energy absorption (impact) for flat safety glass and safety plastics for use in buildings. These requirements are intended to reduce the risk of injuries caused by cutting and piercing in accidents where these materials are involved.
ISO 9001 is a certified quality management system (QMS) for organisations who want to prove their ability to consistently provide products and services that meet the needs of their customers and other relevant stakeholders.
