ASTM F2216-17 可选强度设备的标准规范

1.1 This specification establishes parameters for the design and manufacture of selectorized strength training equipment as defined in 3.1. 1.2 It is intended that these fitness products be used in an indoor setting or environment. 1.3 It is the intent of this standard to specify fitness products for use only by individuals age 13 and older. 1.4 This standard is to be used in conjunction with Specification F2276, Test Methods F2571, and Test Method F2277. 1.5 This standard takes precedence over Specification F2276 and Test Methods F2571 in areas that are specific or unique to selectorized strength training equipment. 1.6 This specification2 establishes additional requirements for the design of commercial fitness equipment for use by people with functional limitations or impairments. 1.7 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only. 1.8 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. 1.9 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.

Standard Specification for Selectorized Strength Equipment

ASTM F2277-17a 评定选定强度设备设计和性能特性的标准试验方法

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 deflectio......
