Standard Test Method for Determination of Operating Force of Sliding Windows and Doors

1.1 This test method determines the operating forces for opening and closing horizontal and vertical sliding windows and horizontal sliding door systems. It does not address the forces required for opening pivoting, projecting, or other fenestration systems. This test method does not address the use or performance of add-on devices or mechanical operators that might be installed to reduce operating forces of sliding windows or doors. It deals only with the forces necessary to open and close a sash or panel through the direct application of force to the operable sash or panel.

1.2 This test method is suitable for laboratory product comparisons or for qualifying products, or both, as meeting window or door operating force specifications. This test method is also suitable for use in the field to determine the operating forces required to open and close installed sliding windows and doors.

1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

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.
