Standard Specification for
Plain and Steel-Laminated Elastomeric Bearings for
Bridges1

This standard is issued under the fixed designation D 4014; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This specification covers bearings, which consist of all
elastomer or of alternate laminates of elastomer and steel,
when the function of the bearings is to transfer loads or
accommodate relative movement between a bridge superstructure and its supporting structure, or both.

1.2 The values stated in SI units are to be regarded as the
standard.
NOTE 1—The words “elastomer” or “elastomeric” will be used interchangeably with the word “rubber” in this specification.

1.3 The following safety hazards caveat pertains only to the
test methods portion, Section B, of this specification: This
the 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.
