1. Scope
1.1 These practices describe standardized techniques for locating air leakage in building envelopes.
1.2 These practices offer a choice of methods to determine air leakage sites with each method offering certain advantages.
1.3 Some of the practices require a knowledge of infrared scanning, building pressurization or 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 This standard does not purport to address all of the safety problems, 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 7.
