CE marked The CE mark is the ultimate assurance of Perko Powermatic®'s suitability for use on fire doors. All products used in buildings must comply with the Construction Products Regulations (CPR). The CPR state that, where applicable, products must meet the 6 essential requirements of the Construction Products Directive, which are: Mechanical resistance and stability. Safety in case of fire. Hygiene, health and the environment. Safety in use. Protection against noise. Energy consumption and heat retention. In the case of Perko Powermatic®, it is the first two in the above list which are most relevant and which govern a product's suitability for fire doors. The CE mark denotes the product's compliance with the performance requirements of BS EN 1154:1997 for power size 3 controlled door closing devices, as certified by an independent test laboratory In addition to compliance with BS EN 1154:1997 itself, Perko Powermatic® must also meet the requirements of the fire testing standard BS EN 1634-1 and must be manufactured under a recognised factory production control system, BS EN ISO 9001:2000. When a product, such as Perko Powermatic® carries the CE mark, responsibility for the product's compliance with the appropriate standards falls on the manufacturer. It is for this reason that the CE mark on every Perko Powermatic® represents such an excellent means of establishing its suitability for use on fire doors. The mark can be found on both the product's packaging and on the end plates of the product itself. View declaration of conformity
