Proposing Revisions. Revisions are made periodically to the Standard to incorporate changes thatappear necessary or desirable, as demonstrated bythe experience gained from the application ofthe Standard. Approved revisions will be published periodically. The Committee welcomes proposals for revisions to this Standard. Such proposals should be as specific as possible, citing the paragraph number(s), the proposed wording, and a detailed description of the reasons for the proposal, including any pertinent documentation. Proposing aCase. Cases maybe issued to provide alternative rules when justified, to permitearlyimplementation of an approved revision when the need is urgent, or to provide rules notcovered byexisting provisions. Cases are effective immediately upon ASME approval and shall be posted on the ASME Committee web page. Requests for Cases shall provide a Statement of Need and Background Information. The request should identify the Standard and the paragraph, figure, or table number(s), and be written as a Question and Reply in the same format as existing Cases. Requests for Cases should also indicate the applicable edition(s) ofthe Standard to which the proposed Case applies. Interpretations. Upon request, the BPE Standards Committee will renderan interpretation ofanyrequirementofthe Standard.InterpretationscanonlyberenderedinresponsetoawrittenrequestsenttotheSecretaryoftheBPEStandards Committee. Requests for interpretation should preferably be submitted through the online Interpretation Submittal Form. The form is accessible athttp://go.asme.org/InterpretationRequest. Upon submittal ofthe form, the Inquirer will receive an automatic e-mail confirming receipt.
MM-9.1.1 ð22Þ Wrought, Cast, and Welded Fabricated Applications (a) Listing ofthe alloy in an industry-recognized spec- ificationorstandardincludingtensilestrength properties. (b) Evidence that the proposed material, in both the wroughtandwelded conditions, will have corrosionresis- tance equal to or greater than 304L stainless steel (UNS S30403) in a service environmentwithin the scope ofthis Standard. Materials that will not be welded (e.g., some castings) do not require corrosion testing in the welded condition. (c) Welded austenitic stainless steel tube shall be capable of passing the weld decay test in ASTM A249/ A249M, Supplement S7 and the intergranular corrosion test in either ASTM A270/A270M, Supplement S1 or ISO 3651-2 Method B. See Nonmandatory Appendix F for additional information. (d) Evidence thatthe material surface can be mechani- cally polished, electropolished, or passivated to meet the applicable requirements of Part SF. (e) Recommended welding process(es), filler metal(s), and evidence showing that the combination of base metal, filler metal(s), and recommended welding process(es) meets the applicable requirements of Parts MJ and SF. Special restrictions, exceptions, or guidance shall be noted.
PM-1 PURPOSE AND SCOPE The purpose of this Part is to provide the basis for selecting and using polymeric and other nonmetallic materials. This Part describes the types of polymeric and other nonmetallic materials and identifies different ways to characterize materials. PM-2 MATERIALS Polymeric and nonmetallic materials have found wide- spread use in bioprocessing equipment because of their broad range of physical and chemical properties, their ability to be formed into complex shapes, and their biocompatibility. Polymeric materials may be used in a range of applications including static and dynamic seals, hoses, pumps, tubing, barrier coatings, diaphragms, valves, and filters. The choice ofmaterial class depends on the design requirements and material performance, both as installed and during use. For in-depth discussion and guidance on polymeric and nonmetallic materials, see Nonmandatory Appendix O. PM-2.1 Materials of Construction Materials of construction shall be selected to maintain the purity and integrity ofthe product/process fluid. It is the owner/user’s responsibility to select the appropriate materials ofconstruction for the conditions ofuse. Mate- rials should be compatible with the stated processingcon- ditions, cleaning solutions (where appropriate), and sterilizing conditions (where appropriate), etc., as speci- fied bythe owner/user. The followingsections outline the major classes ofpolymeric and nonmetallic materials and their requirements for use in bioprocessing equipment.
