1.1 These test methods specify procedures and equipment used for testing and evaluating stationary exercise upright and recumbent bicycles and ergometers for compliance to Specification F1250 . Both design and operational parameters will be evaluated. Where possible and applicable, accepted test methods from other recognized bodies will be used and referenced. In the case of a conflict between this document and Specification F1250 , Specification F1250 takes precedence. 1.2 Requirements— Stationary exercise bicycles and ergometers are to be tested for the parameters specified in Specification F2276 and Test Methods F2571 and the following parameters unique to this equipment: 1.2.1 Seat post construction and loading, 1.2.2 Handlebar construction and loading, 1.2.3 Pedal construction and loading, 1.2.4 Crank arm and enclosure entrapment, 1.2.5 Seat back support loading, 1.2.6 Stability, 1.2.7 Direct Drive Exercise Bicycle Pedal Endurance, 1.2.8 Warnings, and 1.2.9 Documentation. 1.3 This test method 2 contains additional requirements to address the accessibility of the equipment for persons with disabilities. 1.4 Units— The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. 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. ====== Significance And Use ====== 4.1 The purpose of these test methods is to provide reliable and repeatable test methods for the evaluation of stationary exercise bicycles and ergometers assembled and maintained according to the manufacturer’s specifications. Use of these test methods in conjunction with Specifications F1250 and F3021 is intended to ensure appropriate performance and reliability of said equipment and reduce the risk of serious injury from design deficiencies.
