1.1 These test methods establish procedures for conducting tests to determine the structural performance properties of bicycle frames. 1.2 These test methods describe mechanical tests for determining the following performance properties: 1.2.1 Frame Fatigue – Horizontal Loading 1.2.2 Frame Fatigue – Vertical Loading 1.2.3 Falling Mass – Horizontal Loading 1.2.4 Falling Frame – Vertical Loading 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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. 1.5 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 ====== 5.1 These tests are used to verify the durability and strength of a bicycle frame.
