SECTION I GENERAL This summary of changes to Section I of the ASME Code is not all inclusive and contains the changes we consider most important to our clients. Please remember to use the Code for actual requirements. The 2011 Addenda to the Code become mandatory January 1, 2012. This addenda was printed on white paper and was printed in its entirety. Also please note that Footnotes have been changed to Endnotes and these endnotes are part of the Standard. ASME will no longer issue addenda. The next edition of the Code will be issued in 2013 and then issued every 2 years thereafter. Code Case Supplements will be published two times a year. Interpretations will be posted on the ASME website at http://cstools.asme.org/Interpretations.cfm in January and July of each year. What ASME calls a “Special Notice” may be posted on the website prior to the 2013 Edition to provide approved revisions to Code requirements. These revisions may be used upon issuance but become mandatory 6 months after issuance. “Errata” to the Code will also be posted on the ASME website to provide corrections. Errata are typographical or grammatical errors. These “Special Notices” and “Errata” can be found at http://www.asme.org/kb/standards/publications/bpvc-resources or http://cstools.asme.org/BPVErrataAndSpecialNotice.cfm

SECTION I GENERAL The ASME is phasing out multiple stamps and moving to a single mark. The major driver behind this change is to fully protect the marks. As the ASME needs to register marks in the more than 100 countries in which stamped equipment is used, the use of a single mark allows ASME to register one mark in these countries thus making it easier to afford greater protection of a single mark rather than lesser protection for multiple marks. The proposed schedule for implementing the move to a single ASME certification mark will be publication in the 2011 Addenda to the Code. There will be a transition period during which a Manufacturer or Constructor would be able to use either one of the 25 applicable current marks or the single mark. Use of the single mark would then become mandatory on January 1, 2013. There will be a policy statement in the front of the ASME Code books describing this transition period and an implementing Code Case in both the BPV and Nuclear Code Case Books. Each stamp holder must go to ASME’s CA connect (http://www.caconnect.asme.org), establish an account if they have not already and request the new Mark. ASME will not be sending individual notifications of this to the stamp holders – It is up to the stamp holders to independently request this new mark An example of how the stamping may appear In the case of Section I, the Designator that will appear directly under the Certification Mark as “S”, “A" or “PP".
