BS EN 1279‑3 is part three of a multi-series of European standards on insulating glass units in building which covers long term test method and requirements for gas leakage rate and for gas concentration tolerances.
BS EN 1279‑3 describes the test method for the determination of gas leakage rate and specifies the requirements for limit values for gas leakage rate and gas concentration for gas filled insulating glass units made
BS EN 1279-3 on Insulating glass - gas leakage and concentration tolerances is useful for:
Insulated Glass combines two or more glass panes that are spaced apart and sealed with a sealant to appear as a single unit. Also called double glazing, IGUs are designed to reduce heat loss and solar heat gain entering the building, while reducing visible light transmittance. Hence they improve the thermal performance, and reduce energy costs. They can be fabricated to meet sound control requirements, seismic requirements, bullet resistance, hurricane and blast resistance requirements, impact resistance and state energy codes.
The leak rate is defined as the pV throughput of a gas through a leak. It is a function of the type of gas, pressure difference, and temperature.
With the use of BS EN 1279-3, you can evaluate the gas leakage rate and gas concentration tolerances in buildings, and with this information you make the necessary changes required to the production of glass so as to safeguard the users of your product. Ensuring this quality audit can help build credibility between your customers.
