【国外标准】 Standard Test Methods for Evaluating Design and Performance Characteristics of Selectorized Strength Equipment

4.1 The purpose of these test methods is to provide valid and repeatable test methods for the evaluation of selectorized strength equipment assembled and maintained according to the manufacturer’s specifications. Use of these test methods in conjunction with Specification F2216 is intended to maximize the reliability of selectorized strength equipment design and reduce the risk of serious injury resulting from design deficiencies.1.1 These test methods specify procedures and apparatus used for testing and evaluating selectorized strength equipment for compliance to Specification F2216. Both design and operational parameters will be evaluated. Where possible and applicable, accepted test methods from other recognized bodies will be used and referenced.1.2 Requirements—Selectorized strength equipment is to be tested in accordance with these test methods or Test Methods F2571 for all of the following parameters:1.2.1 Stability,1.2.2 Edge and corner sharpness,1.2.3 Tube ends,1.2.4 Weight stack travel,1.2.5 Weight stack selector pin retention,1.2.6 Function of adjustments and locking mechanisms,1.2.7 Handgrip design and retention,1.2.8 Assist mechanisms,1.2.9 Foot supports,1.2.10 Rope and belt systems:1.2.10.1 Static load,1.2.10.2 End fitting design,1.2.11 Chain drive design,1.2.12 Pulley design:1.2.12.1 Rope pulley design,1.2.12.2 Belt pulley design,1.2.13 Entrapment zones,1.2.14 Pull in points,1.2.15 Weight stack enclosure design,1.2.16 Loading and deflection:1.2.16.1 Intrinsic loading and associated deflection,1.2.16.2 Extrinsic loading and associated deflection,1.2.16.3 Endurance loading,1.2.17 Documentation and warnings verification, and1.2.18 Additional universal design and construction requirements.1.3 This test method2 contains additional requirements to address the accessibility of the equipment for persons with disabilities.1.4 The values stated in SI units are to be regarded as the standard. The values in parenthesis are for information only.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.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.
