AN INTERNATIONAL STANDARD

ASME Y14.5-2018

(Revision of ASME Y14.5-2009)

Date of Issuance: February 11, 2019

This Standard will be revised when the Society approves the issuance of a new edition.

Periodically certain actions of the ASME Y14 Committee may be published as Cases. Cases are published on the ASME website

under the Y14 Committee Page at http://go.asme.org/Y14committee as they are issued.

Errata to codes and standards may be posted on the ASME website under the Committee Pages to provide corrections to

incorrectly published items, or to correct typographical or grammatical errors in codes and standards. Such errata shall be used

on the date posted.

The Y14 Committee Page can be found at http://go.asme.org/Y14committee. There is an option available to automatically

receive an e-mail notification when errata are posted to a particular code or standard. This option can be found on the

appropriate Committee Page after selecting “Errata” in the “Publication Information” section.
