It can be us
27、ed, for example,a) to measure the air permeability of a building or part thereof for compliance with a design air-tightness specification,b) to compare the relative air permeability of several similar buildings or parts of buildings, andc) to determine the air-leakage reduction resulting from indivi
28、dual retrofit measures applied incrementally to an existing building or part of building.The fan pressurization method does not measure the air infiltration rate of a building. The results of this method can be used to estimate the air infiltration rate and resulted heat load by means of calculation
29、.Other methods, like tracer gas, are applicable when it is desired to obtain a direct measurement of the air infiltration rate. A single tracer gas measurement, however, gives limited information on the performance of ventilation and infiltration of buildings.The fan-pressurization method applies to
30、 measurements of air flow through the construction from outside to inside or vice versa. It does not apply to air flow measurements from outside through the construction and back to outside.The proper use of this International Standard requires knowledge of the principles of air flow and pressure me
31、asurements. Ideal conditions for the test described in this International Standard are small temperature differences and low wind speeds. For tests conducted in the field, it needs to be recognized that field conditions can be less than ideal. Nevertheless, strong winds and large indoor-outdoor temp
32、erature differences are to be avoided.5DIN EN ISO 9972:2015-12EN ISO 9972:2015 (E)1 ScopeThis International Standard is intended for the measurement of the air permeability of buildings or parts of buildings in the field. It specifies the use of mechanical pressurization or depressurization of a bui
33、lding or part of a building. It describes the measurement of the resulting air flow rates over a range of indoor-outdoor static pressure differences.This International Standard is intended for the measurement of the air leakage of building envelopes of single-zone buildings. For the purpose of this
34、International Standard, many multi-zone buildings can be treated as single-zone buildings by opening interior doors or by inducing equal pressures in adjacent zones.International Standard does not address evaluation of air permeability of individual components.2 Normative referencesThe following doc
