Norm ASTM E1186-03R09
1.1 These practices cover standardized techniques for locating air leakage sites in building envelopes and air barrier systems.
1.2 These practices offer a choice of means for determining the location of air leakage sites with each offering certain advantages for specific applications.
1.3 Some of the practices require a knowledge of infrared scanning, building and test chamber pressurization and depressurization, smoke generation techniques, sound generation and detection, and tracer gas concentration measurement techniques.
1.4 The practices described are of a qualitative nature in determining the air leakage sites rather than determining quantitative leakage rates.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 6.
