1、Designation: F 2115 05An American National StandardStandard Specification forMotorized Treadmills1This standard is issued under the fixed designation F 2115; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision
2、. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.INTRODUCTIONThe goal of this specification is to promote proper mechanical design and manufacturing practicesfor motorized treadmills. Through
3、 these practices, this specification aims to assist designers andmanufacturers in producing functional, safe machines under proper operational conditions. Theequipment user must recognize, however, that a standard alone will not necessarily prevent injuries.Like other physical activities, exercise i
4、nvolving treadmills involves the risk of injury, particularly ifthe equipment is used improperly. The designers and manufacturers of treadmills should also considerother standards including, but not limited to, those listed below. This specification does not apply totreadmills designed for underwate
5、r use.1. Scope1.1 This specification covers the establishment of param-eters for the design and manufacture of motorized treadmills.1.2 It is intent of this specification to specify products foruse by individuals age 12 and above.1.3 The values stated in SI units are to be regarded as thestandard. T
6、he values given in parentheses are for informationonly.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility
