EN 13180:2001 (E)5IntroductionThis standard has been prepared to:– specify dimensions and tolerances for flexible ducts;– give methods for the performance testing of flexible ducts;– and enable assessment of minimum technical requirements.However because of the different types of flexible ducts and the various requirements in eachapplication, some technical characteristics are presented as classes and may differ depending on thematerials used.This standard can be used for the following applications:– testing of components during and after manufacturing;– attestation purposes.Temperature characteristics are supplied by the manufacturer.1 ScopeThis standard specifies requirements and test methods for the technical characteristics of flexibleducts used in ventilation and air conditioning installations in buildings for human occupancy.This standard identifies the following parameters which shall be tested or inspected:– dimensions and tolerances;– mechanical resistance.Acoustic, thermal, reaction to fire, and pressure loss properties of flexible ducts are not covered in thisstandard.2 Terms and definitionsFor the purposes of this European Standard, the following terms and definitions apply.2.1 flexible ductduct which can be manually longitudinally compressed or decompressed and flexed withoutpermanently damaging the cross section areaSIST EN 13180:2002
