INTERPRETATIONS
NO. 46 — SECTION XI
Replies to Technical Inquiries
July 1, 1999 through December 31, 1999
FOREWORD
General Information
This publication includes all written interpretations issued between the indicated dates by the ASME
Staff on behalf of the ASME Boiler and Pressure Vessel Committee in response to inquiries concerning
interpretations of the ASME Boiler and Pressure Vessel Code. A contents is also included that lists
subjects specific to the interpretations covered in the individual volume.
These interpretations are taken verbatim from the original letters, except for a few typographical
and editorial corrections made for the purpose of improved clarity. In some instances, a review of the
interpretation revealed a need for corrections of a technical nature. In these cases, a revised interpretation
is presented bearing the original Interpretation Number with the suffix R and the original file number
with an asterisk. Following these revised interpretations, new interpretations and revisions to them
issued during the indicated dates are assigned Interpretation Numbers in chronological order. Interpretations
applying to more than one Code Section appear with the interpretations for each affected Section.
ASME procedures provide for reconsideration of these interpretations when or if additional information
is available that the inquirer believes might affect the interpretation. Further, persons aggrieved by an
interpretation may appeal to the cognizant ASME committee or subcommittee. As stated in the Statement
of Policy in the Code documents, ASME does not “approve,” “certify,” “rate,” or “endorse” any item,
construction, proprietary device, or activity.
Each interpretation applies to the Edition and Addenda stated in the interpretation, or if none is
stated, to the Edition and Addenda in effect on the date of issuance of the interpretation. Subsequent
revisions to the Code may supersede the interpretation.
For detailed instructions on preparation of technical inquiries to the ASME Boiler and Pressure
Vessel Committee, refer to Appendix V in Division 1, Appendix III in Division 2, and Appendix VI
in Division 3.
Subject and Numerical Indexes
Subject and numerical indexes have been prepared to assist the user in locating interpretations by
subject matter or by location in the Code. They cover interpretations issued from Volume 12 up to
and including the present volume, and will be updated with each volume.
