Overview
This European Standard describes the application of the tracer gas dilution method to determine the ventilation rate/specific airflow rate in a building space, which is considered to be of a single zone. The measurement method is valid in 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 International Standard provides three measurement methods using a tracer gas: (1) concentration decay method, (2) continuous dose method, and (3) constant concentration method. Specific measurement conditions are given in Table 1. The committee responsible for this standard is NA 005-56-93 AA "Luftdichtheit" ("SpA zu ISO/TC 163/SC 2/WG 4") ("Airtightness (mirror committee for ISO/TC 163/SC 2/WG 4)") at DIN.
