Chimneys - Elastomeric seals and elastomeric sealants - Material requirements and test methods - Part 1: Seals in flue liners

This European Standard specifies the material requirements and test methods for prefabricated elastomeric seals for use in flue liners. It also specifies the requirements for evaluation of conformity.
These seals are components in flue liners of different materials like metal, plastic, clay, concrete etc.
Performance requirements of elastomeric seals in flue liners are covered by the relevant product standards.
In the product 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. 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 wood,  )
-   corrosion resistance class 3.

Introduction
The objective of this European Standard is to evaluate the material behaviour of prefabricated elastomeric
seals for application in flue liners.
The testing conditions are representative of normal use, yet severe enough to yield meaningful results in a
relatively short period of time.
1 Scope
This European Standard specifies the material requirements and test methods for prefabricated elastomeric
seals for use in flue liners. It also specifies the requirements for evaluation of conformity.
These seals are components in flue liners of different materials like metal, plastic, clay, concrete etc.
Performance requirements of elastomeric seals in flue liners are covered by the relevant product standards.
In the product 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. 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:
1)
 corrosion resistance class 2 concerning natural wood,
 corrosion resistance class 3.
