DESCRIPTION
BS EN ISO 12569:2017
This standard BS EN ISO 12569:2017 Thermal performance of buildings and materials. Determination of specific airflow rate in buildings. Tracer gas dilution method is classified in these ICS categories:
- 91.120.10 Thermal insulation of buildings
This document establishes methods to obtain the ventilation rate or specific airflow rate in a building space (which is considered to be a single zone) using a tracer gas.
The measurement methods apply for spaces where the combined conditions concerning the uniformity of tracer gas concentration, measurement of the exhaust gas concentration, effective mixed zone and/or fluctuation of ventilation are satisfied.
This document provides three measurement methods using a tracer gas: concentration decay method, continuous dose method, and constant concentration method.
NOTE Specific measurement conditions are given in Table 1.
