(Test Method)Standard Test Method for Evaluating the Engagement Between Windows and Insect Screens as an Integral System
Standard Test Method for Evaluating the Engagement Between Windows and Insect Screens as an Integral System
SIGNIFICANCE AND USE
5.1 This test method is a design tool to evaluate the engagement between the window and insect screen under static loading. The ability of insect screens to remain engaged depends on the magnitude, duration, repetition of loads, and the method of engagement. The platen size and shape were chosen to prevent screen cloth damage during static loading. The 60-s duration was arbitrarily chosen to standardize this test method.
5.2 This test method is not intended for evaluating retention of woven screen mesh to a screen frame.
Note 1: The procedure described in SMA/SMT 31 is one method that has been developed for such evaluation.
5.3 This test method is not intended for evaluating retention of security or protection screens used as a deterrent against vandalism or forced entry.
Note 2: The procedure described in ANSI/SMA 6001 is one method that has been developed for such evaluation.
5.4 This test method is not intended for evaluating the retention of insect screens being used as a restraint of occupants within the building as a means of preventing accidental falls.
5.5 This test method is not intended for evaluating retention of insect screens for their ability to withstand impacts from windborne debris as might develop during hurricanes or other windstorm events.
SCOPE
1.1 This test method covers the evaluation of the static load resistance of an insect screen in its functional position in a window under load conditions prescribed by appropriate specifying authorities.
1.2 This test method is applicable to insect screens larger than 12 in. (300 mm) in least dimension that can be accessed from both the interior and exterior direction when the insect screen is in the functional position.
1.3 This test method evaluates both the interior and exterior static load resistance of the insect screen attachment to the window frame.
1.4 This test method describes the apparatus and the procedure to be used for applying static loads to specimens.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
