(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
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 the standard. The SI values given in parentheses are for information only.
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.
