Generl. ASME Standards are developed and maintained with the intent to represent the consensus of concerned interests. As such, users of this Standard may interact with the Committee by requesting interretations, proposing revisions, and attending Committee meetings. Correspondence should be addressed to: Secretary, B16 Main Committee The American Society of Mechanical Engineers Three Park A venue New York, NY 10016-5990 Proposing Revisions. Revisions are made periodically to the Standard to incorporate changes that appear necessary or desirable, as demonstrated by the experience gained fom the application of the Standad. Approved revisions will be published periodically. The Committee welcomes proposals for revisions to this Standard. Such proposals should be as specifc as possible, citing the paragraph number(s), the proposed wording, and a detailed description of the reasons fr the proposal, including any pertinent documentation. Interpretations. Upon request, the B 16 Committee will render an interretation of any requirement of the Standard. Interpretations can only be rendered in response to a written request sent to the Secretary of the B 16 Main Committee. Te request fr interretation should be clear and unambiguous. It is further recommended that the inquirer submit his/her request in the fllowing frmat: Subject: Edition: Question: Cite the applicable paragraph number(s) and the topic of the inquiry. Cite the applicable edition of the Standard fr which the interretation is being requested. Phrase the question as a request fr an interpretation of a specifc requirement suitable fr general understanding and use, not as a request fr an approval of a proprietary design or situation. The inquirer may also include any plans or drawings, which are necessary to explain the question; however, they should not contain proprietary names or infration. Requests that are not in this frmat will be rewritten in this frmat by the Comittee prior to being answered, which may inadvertently change
( d) Connections shall confr to sizes and dimen­ sions listed in Table 1 or 2. Joint connections are designed fr use with hubless soil pipe couplings con­ frming to the requirements of the Cast Iron Soil Pipe Institute Specifcation 310-85. 3 SIZES (a) Sizes and dimensions of fttings shall confrm to dimensions in Table I or 2. (b) Opening size sequence is illustrated in Figs. 3 and 4. 4 MARKING (a) Each ftting shall be marked with the manufctur­ er’s name or trademark, and with “Sovent ® .” (b) Fittings of gray cast iron do not require material marking. If the manufcturer elects to use malleable iron or ductile iron, the ftting shall be marked with “Ml” or “DI.” 5 MATERIAL (a) The material used to manufcture the fttings shall be in accordance with ASTM A 126, Grade A. (b) At the option of the manufcturer, fttings may be furnished of malleable iron complying with the requirements of ASTM A 197 or A 47, Grade 32510, or of ductile iron complying with AST A 395 or A 536, Grade 65-45-12. 6 PITCH All nominal 90 deg drain openings shall be pitched down toward the ftting in a slope of Y 4 in./ft (2.1 % ) of horizontal pipe with refrence to a horizontal plane.
8.3 Outside and Inside Diameter of Fitting The diameters shall be within the tolerances shown in Table 3. 8.4 Center-to-End Dimensions The center-to-end dimensions shall be within the tolerances shown in Table 4. 9 ALIGNMENT The maximum allowable variation in the alignment of all openings shall be 0.06 in./f (0.5%), except fr openings that are pitched. 10 TESTS (a) Each ftting shall be subjected to a minimum hydrostatic pressure of 25 psi. The ftting shall not leak water or sweat at any part of the surfce. Alternate tests that demonstrate the same degree of soundness and strength are acceptable. (b) Manufcturers shall inspect fttings prior to ship­ ment for the presence of cracks, holes, or other defcts. ( c) Manufacturers shall be prepared to cerify that their products meet the requirements of this Standard.
