This is the 50thanniversary of NSF/ANSI 14 first published in 1965. In this edit
24、ion of NSF/ANSI 14, the following revisions have been incorporated: Issue 40: This is a revision updating table 2 and table 8. Issue 55: This is a revision to update the normative references. Issue 57: This adds a QC table for ASTM F477. This Standard is referenced in multiple standards already in N
25、SF/ANSI 14 and needs its own table. Issue 58: This clarifies the pass/fail criteria for stress corrosion resistance in section 5.8.2.3. Issue 59: This is a revision updating the reference for flattening resistance and stiffness and removing the well casing testing from Table 5. Issue 63: This change
26、 was to add ASSE 1049 QC requirements to table 21 Air Admittance Value Test Frequency. Issue 64: The purpose of this revision was to add ASTM F679 QC requirements to table 12 and 13. Issue 65: This proposal added ASTM F2806 and F2969 QC requirements to table 5. Issue 66: This revision added ASTM %29
27、69 QC requirements to table 10A. Issue 68: In section 5.7 there were two melthods, this revision corrected the requirement to only one method. Issue 69: This ballot was addressing changes/corrections in Standard 14 found during the publication review process. Issue 70: In this ballot, the reference
28、to CAN/CSA 448 to the most recent edition was corrected. This Standard was developed by the NSF Joint Committee on Plastics using the consensus process described in NSF Standards Development Policies and accredited by ANSI. Suggestions for improvement of this Standard are welcome. This standard is m
29、aintained on a Continuous Maintenance schedule and can be opened for comment at any time. Comments should be sent to Chair, Joint Committee on Plastics at standardsnsf.org, or c/o NSF International, Standards Department, PO Box 130140, Ann Arbor, Michigan 48113-0140, USA. 2 The information contained

32、 requirements for plastic piping system components and related materials. These criteria were established for the protection of public health and the environment. 1.2 Scope The physical, performance, and health effects requirements in this Standard apply to thermoplastic and thermoset plastic piping
33、 system components including, but not limited to, pipes, fittings, valves, joining materials, gaskets, and appurtenances. The established physical, performance, and health effects requirements also apply to materials (resin or blended compounds) and ingredients used to manufacture plastic piping sys
34、tem components. This Standard provides definitions and requirements for materials, ingredients, products, quality assurance, marking, and recordkeeping. Plastic piping system components which are manufactured to one of the normative references in 2 and do not have integral connections specifically i
35、ntended for plastic piping systems are not covered by this Standard. 1.3 Materials, design, and construction For plastic piping system components and materials cited by the references in 2, the materials, design, and construction requirements of this Standard and the applicable product standard(s) i
36、n 2 shall apply. When materials, designs, or constructions are utilized that are not cited in 2, the plastic piping system components and related materials shall comply with the applicable requirements of this Standard. Plastic piping system components and related materials that incorporate material
37、s, designs, or constructions not cited in 2 shall be acceptable, provided that such plastic piping system components and related materials can be demonstrated to be at least equivalent in terms of strength, quality, effectiveness, durability, and safety to those that are cited in this Standard. 2 No
