It covers those activities involved in preparing and issuing the air tightness test report. You must prepare a report which identifies the building tested, the envelope area and the calculations used to arrive at values, as well as the methodology and equipment used.
Overview This standard is for those who produce and issue air tightness reports on the air permeability of buildings of any size or complexity. It covers those activities involved in preparing and issuing the air tightness test report.
X1.4.1 The first option is testing to determine whether or not the air barriers and connections in the wall, window, ceiling/roof and foundation systems of the test enclosure are installed well enough to meet an airtightness target.
3.5 This test method measures the airtightness of the constructed building enclosure. Test methods that measure airtightness of materials (ASTM E2178) or assemblies (ASTM E2357) alone do not address the various complexities of the constructed building enclosure, including design, sequence, constructability, and workmanship.
3.3 This test method is used to determine the airtightness of building enclosures or portions thereof at a specified reference pressure. This is different than field testing of air leakage using tracer dilution methods (see ASTM E741).
Two common airtightness metrics referenced in this standard are: the airflow in air changes per hour required to induce a 50 Pascal pressure difference between the interior of the test enclosure and outdoor air (ACH at 50 Pa).
