Safety & Toughened Glass Testing

BSI has a wealth of experience in the certification and testing of glass related products for the construction industry. Our Kitemark and CE marking services cover a wide range of glass related products in the construction industry including:

  • Safety glass (toughened, heat soaked, laminated glass)
  • Insulating glass units
  • Vehicle glass
  • Glass for domestic appliances

Kitemark Scheme for Insulating Glass Units

Insulating glass units (IGUs) can be defined as a combination of two or more panes of glass with a hermetically sealed air space between the panes of glass. This space may or may not be filled with an inert gas, such as argon.

The Kitemark scheme for insulating glass units is specified by the National House Building Council (NHBC) and the Kitemark is recognised as the best way to identify certified, quality insulating glass units for use in buildings. The NHBC is the leading warranty and insurance provider for new and newly converted homes in the UK and specifies the BSI Kitemark for insulated glass units used in windows for their new homes.


Insulating Glass Unit Testing Facility at BSI

Insulating glass units will continue to be an important factor in the fight to reduce energy consumption and waste whilst at the same time improving efficiency of energy usage.

The BSI testing facility for insulating glass units is the largest and most modern in Europe, with state-of-the-art technology.  It has been established to provide the glazing industry with sufficient testing capacity to allow manufacturers the opportunity to complete the required initial type testing in support of CE marking. BSI’s test facility includes:

  • Gas leakage rate
  • Fogging performance
  • Dew point measurement
  • Moisture absorption capacity
  • Moisture penetration index

Kitemark Scheme for Safety Glass in Buildings

BSI’s long established Kitemark scheme for safety glass has made the Kitemark synonymous with safety and compliance.  With the UK Building Regulations requiring glass used in critical locations within buildings to be safe and the Construction Products Regulation requiring CE marking of safety glass products, the Kitemark scheme for safety glass is ideally placed to provide the necessary evidence for glass processors in support of their claim of compliance.


Safety Glass Testing Facility at BSI

The BSI testing facility has been established to provide the glazing industry with sufficient testing capacity to allow manufacturers the opportunity to complete the required initial type testing in support of CE marking which BSI offers under its Notified Laboratory status. BSI’s test facility includes:

  • Impact testing and classification
  • Mechanical Strength testing
  • Fragmentation testing
  • High humidity and temperature testing

Vehicle Glass and Glass for Domestic Appliances

These Kitemark schemes cover laminated and thermally and chemically toughened glass for use in land transport including rolling stock, as well as thermally toughened glass panels for use in domestic appliances where such panels can be exposed to thermal and/or physical shock and laminated glass for use as ships windows. Our test facility includes:

  • visual properties
  • fragmentation testing
  • thermal shock testing
  • resistance to impact testing
  • stamp testing

Kitemark for Security Glazing

The security of our buildings is of great importance and so BSI has developed a Kitemark scheme for security glazing based upon BS EN 356 - Testing and classification of resistance against manual attack.  The Kitemark is the ideal way to provide evidence of compliance for glazing used in enhanced security doors and windows.
