Standard Test Methods for Wear Testing Rotary Operators for Windows

SIGNIFICANCE AND USE
5.1 These tests provide standard methods for evaluating the mechanical performance of the rotary-type window operators, while the operators are subjected to cyclic wear in opening and closing against the operating moment.
SCOPE
1.1 These test methods describe the wear testing of gear-type rotary operating devices used for opening and closing windows (Note 1).  
1.2 These test methods do not directly determine the effects of varying environmental conditions but may be employed after environmental exposure to evaluate the effect of such exposure.  
1.3 These test methods are not intended to evaluate the structural adequacy of the operator in resisting the maximum force to which it may be subjected.  
Note 1: Certain types of rotary window operators, such as torque-bar operators and telescopic operators cannot be tested by these test methods.  
1.4 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of inch-pound units may be approximate.  
1.5 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. For a specific hazard statement, see 9.1.2.  
1.6 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.
