Things about ASTM-E987: Standard test methods for deglazing force of fenestration products.
1.1 These test methods measure the resistance of elements of fenestration products such as operating (or removable) window sashes, storm sashes, and sliding glass door panels (hereafter referred to as sash members) to forces tending to deglaze the construction.
1.2 These test methods utilize concentrated loads applied to the interior side of a sash member in a manner simulating normal opening and closing forces. Removable sashes are loaded to simulate handling for removal and cleaning.
1.3 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.
1.4 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.
