BS EN 14241-1:2013EN 14241-1:2013 (E) 5 Introduction The objective of this European Standard is to evaluate the material behaviour of prefabricated elastomeric seals for application in flue liners. The testing

22、 conditions are representative of normal use, yet severe enough to yield meaningful results in a relatively short period of time. BS EN 14241-1:2013EN 14241-1:2013 (E) 6 1 Scope This European Standard specifies the material requirements and test methods for prefabricated elastomeric seals for use in

23、 flue liners. It also specifies the requirements for evaluation of conformity. These seals are components in flue liners of different materials such as metal, plastic, clay, concrete. Performance requirements of elastomeric seals in flue liners are covered by the relevant product standards. In the p

24、roduct standards, chimney products, including seals, are tested under operational conditions (e.g. temperature, pressure, mechanical load, flue gas, condensate) to relevant properties such as leakage and deformation. This European Standard covers seals intended for use in both dry and wet conditions

25、. Therefore all seals are tested for functioning under wet conditions. This European Standard does not contain all the requirements necessary for chimneys with the following classification: corrosion resistance class 2 concerning natural wood1), corrosion resistance class 3. This European Standard i

26、s also applicable for sealants, in case nothing else is defined. The specimens are made from the sealants, which have been brought into a practical form, cured under manufacturers instructions. The cured sealants will fulfil the same requirements as seals. NOTE Cured sealants are operationally seals
