ASTM D5212-03 PDF

Scope: 1.1 This specification covers bridge bearings which consist of a confined elastomeric element encased in steel (pot bearings) when the function of the bearing is to transfer loads or accommodate relative movement including rotation between a bridge superstructure and its supporting structure, or both. 1.2 This specification covers the requirements of pot bearings with standard horizontal loads (10 % of vertical). 1.3 The requirements stated in this specification are the minimums necessary for the manufacture of quality bearing devices. It may be necessary to increase these minimum values due to design conditions. 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are for information only. 1.5 The following safety hazards caveat pertains only to the test method portion, Section 7, of this specification: 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.
