The test method can be adapted for the latter purpose, provided the potential paths of air movement and the sources of infiltration and exfiltration can be identified, controlled, or eliminated. There is a strong possibility that the test method or the test apparatus may, by virtue of their design and use, induce air leakage that does not occur under natural environmental exposure. Persons interested in laboratory testing of fenestration products should reference Test Method E The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.

The test specimen consists of the major components of the assembly, including all joints, cracks, or openings between such components and any panning, receptors, extenders, sills, mullions, or other parts or components used for assembly and installation.

The test specimen excludes any joints, cracks, or openings between the assembly and any interior or exterior trim that is not an integral part of the system, and excludes any joints, cracks, or openings between the assembly and the adjacent wall construction. Current edition approved Oct. Published April Originally approved in Discontinued June and reinstated as E — Where two suchoperable parts meet, the two adjacent lengths of perimeter shall be counted as only one length.

Summary of Test Method 4. NOTE 1—The air pressure differences acting across a building envelope vary greatly. The factors affecting air pressure differences and the implications of the resulting air leakage relative to the environment within buildings are discussed in the literature. Air may be supplied to or exhausted from wall cavities or adjacent construction, or may bypass interior or exterior trim or components in a manner not experienced during normal operation or exposure.

Care must be taken to prevent such leakage from occurring, or consideration must be given that such leakage may have occurred during the test. Air leakage from the adjacent wall cavity through sill, head, and jambs of the window frame is considered extraneous air leakage and, therefore, not a component of the measured specimen air leakage.

Such extraneous air leakage through the perimeter frame of the test specimen can be a signi? Apparatus 6. Any suitable arrangement of equipment capable of maintaining the required test tolerances is permitted. At no time during the test shall the sheet or any other part of the testing assembly, come in contact with or restrict any point where air leakage may occur. At least one static air pressure tap shall be provided on each side of the 5.

Consideration must be given to the proper selection of test specimens, the choice of appropriate test technique when a choice is given within this test method , and the proper use and interpretation of the results obtained from this test to minimize the effect of these conditions.

Preparation of Test Specimen Record all pertinent observations. NOTE 5—The purpose of this examination is to record the physical condition of the test specimen and adjacent construction at the time of testing. Examples of pertinent observations to be recorded include: any damage or deterioration observed; missing or broken components; misalignment or misadjustment of weatherstrip or other components; cleanliness of the test specimen; out-of-square installation; etc.

Preparation of Test Apparatus If possible, exclude from the test chamber those joints, cracks, or openings for which air leakage is not to be determined, or tape or otherwise seal such openings to prevent leakage from occurring during the test.

Provide suitable support for the test chamber so that it does not contact or restrict any point where air leakage may occur.

NOTE 7—The accurate measurement and handling of extraneous air leakage is an important factor in conducting these tests. Inaccurate measurement or handling of extraneous air leakage can result in the test reporting higher or lower air leakage measurements than may actually exist. Care must be taken in the location, sealing, and removal of the polyethylene? Extraneous air leakage measurements must also be conducted at the precise test pressure differences to be used during the air leakage tests.

Tests should be conducted when outdoor wind and indoor pressure changes are at a minimum, or steps should be taken to minimize their effect.

When such conditions cannot be corrected, the range of static air pressure differences observed and the average static air pressure difference shall be recorded. Measure and record the speed and direction of the air movement wind at or near the exposed surface of the test specimen. Such measurements shall be taken immediately prior to or during the test. NOTE 10—The measured air leakage through the test specimen is affected by the density and viscosity of the air. Tests should be conducted as near to the reference standard conditions as possible.

NOTE 11—If tests are to be conducted at extremes of outdoor temperature and humidity, that is, near or below freezing, consideration must be given to the effect of such extremes on the accuracy and serviceability of the test apparatus as well as the effect on the measured air leakage.

Calculation Calibration When complete, that document will be referenced. However, all test apparatus shall be calibrated at a minimum of every 6 months to the tolerances established in Section 6. The procedures for this calibration are, at this time, the responsibility of the testing agency.

Such comparisons may not be valid unless the components being tested and compared are of essentially the same size, configuration, and design.
