Bibliography

This European Standard specifies requirements and test methods for metal flue ducts material independent air supply ducts for room sealed appliances.It also specifies the requirements for marking, manufacturer's instruction, product information and evaluation of conformity.NOTE 1Recommendations for preferred dimensions of products are given in the informative Annex A.NOTE 2In this European Standard, only general requirements are specified for elastomeric and plastic components. Elastomeric and plastic products used in flue systems are covered by separate standards, i.e. EN 14241-1 and EN 14471.nformity.
