This Standard will be revised when the Society approves the issuance of a new edition.
ASME issues written replies to inquiries concerning interpretations of technical aspects of this Standard. Interpretations
are published on the Committee Web page and under go.asme.org/InterpsDatabase. Periodically certain actions of
the ASME B89 Committee may be published as Cases. Cases are published on the ASME Web site under the B89
Committee Page at go.asme.org/B89committee as they are issued.
Errata to codes and standards may be posted on the ASME Web site under the Committee Pages to provide correc-
tions 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 B89 Committee Page can be found at go.asme.org/B89committee. There is an option available to automatically

This code or standard was developed under procedures accredited as meeting the criteria for American National Standards. The
Standards Committee that approved the code or standard was balanced to assure that individuals from competent and concerned interests
have had an opportunity to participate. The proposed code or standard was made available for public review and comment that provides
an opportunity for additional public input from industry, academia, regulatory agencies, and the public-at-large.

Participation by federal agency representative(s) or person(s) affiliated with industry is not to be interpreted as government or industry
endorsement of this code or standard.
