Simultaneously, a Sub Task Group wasformed to investigate the issue

18、 of acrylic window design life versus service life. The design lifeis based on the PVHO window being exposed to the maximum allowable working pressure(MAWP), at the maximum rated temperature, for the maximum number of (design) cycles, inan outdoor weathering environment. The majority of PVHOs are no

19、t operated to such extremes,and service life may indeed be longer than design life. Conversely, if a window is not properlycared for (i.e., becomes exposed, either operationally or nonoperationally, to other detrimentalfactors that are not, and cannot be, factored into the design life), then the act

20、ual service life couldbe much shorter than the design life. Thus, the recommendation was made that design life andservice life be addressed as two different subjects. In 1999 the In-Service Task Group became aPVHO subcommittee, with the most immediate task being the establishment of in-service crite

21、riafor PVHO windows and viewports.This Standard provides the necessary in-service criteria to supplement Section 2, Viewports,of ASME PVHO-1, which applies to new construction only. By comparison, this Standard appliesto all PVHO-1 acrylic windows, regardless of their date of manufacture. This Stand

22、ard consistsof both Technical Criteria and Guidelines. They are intended to provide guidance to the Userand/or the Jurisdictional Authority in regard to the establishment of potential Service Life, andthe necessary care, inspection, and repair during that Service Lifedepending on the actualservice c

23、onditions to which the PVHO and windows have been, or will be, exposed.Finally, this Standard was prepared as a “stand-alone” document. All Forms additional tothose normally supplied with the window in accordance with PVHO-1, which may be necessarythroughout the service life of the window, are provi

24、ded herein. Similarly, all necessary PVHO-1technical data applicable to service and repair (if required) are also provided in this Standard.The 2016 Edition of PVHO-2 includes revisions to the in-service pressure testing and tempera-ture abuse factors requirements. It also includes an updated defini

25、tion for “refurbishment” aswell as two new Nonmandatory Appendices covering operation of submersible craft and checklistsand logs intended for operation of PVHOs.Previous editions of this Standard were issued in 2003 and 2012. The 2016 Edition of thisStandard was approved by the American National St
