Structures not requiring AASHTO LRFD design are to be designed using the loads specified in ASTM C857 or ASTM C890, as applicable. 1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only. 1.3 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. 1.4 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.
