EN 13384-1 : 2015+A1:2019 : Chimneys - Thermal and fluid dynamic calculation methods - Part 1: Chimneys serving one combustion appliance.

This standard specifies methods for calculating the thermal and aerodynamic characteristics of chimneys serving a single appliance. These methods apply to chimneys operating under negative or positive pressure, in wet or dry conditions, and connected to heat generators using fuels for which the flue gas characteristics required for the calculations are known. Part 2 deals with chimneys serving multiple appliances, whether collective flue systems or cascade configurations. Part 3 describes the methods for developing charts and tables for chimneys serving a single heat generator.
