This standard covers devices to be used in emergency situations where people are familiar with the emergency exit and its hardware and therefore a panic situation is most unlikely to develop. Lever handle operated escape locks or push pads may therefore be used.<\/p>\n\n\n\n

BS EN 179 classifies emergency exit devices by using a 10-digit coding system, each digit referring to a particular feature of the product measured against the standards performance requirement.<\/p>\n\n\t<\/div>\n\n\n\n

Products covered by BS EN 179:2008 have three identified categories and have the opportunities of greater security than devices covered by BS EN 1125:2008. This is because BS EN 179 devices are subject to testing with doors under greater pressure.
Grade 2:<\/strong> 1,000 N

Fire door hardware specification issues<\/h3>\n\n\t<\/div>\n\n\n\n
\n\t\t\t\n\n

The UK construction products regulations require panic\/emergency exit hardware to be safe and durable. European standards BS EN 1125\/179 are the recognised way of demonstrating compliance and they require that an official notified body proves both the product and the manufacturers factory production controls before CE marking can be applied.
With effect from October 2003 European law recommends all relevant panic\/emergency exit hardware be CE marked when fitted to a fire door.<\/p>\n\n\t<\/div>\n\n\n\n
