For pipe made by a multiple head, extrusion technique with intermediate storage before marking, a code indicating the week, rather than the day, of production is acceptable. In instances where the manufacturer has more than one plant location or produces for other suppliers or distributors, an identifying symbol shall be used. 8.3 Fittings and appurtenances The manufacturer shall place on all plastic fittings and appurtenances the designations and identifications required in the applicable standards as referenced in 2 of this Standard. The fittings and appurtenances shall also bear an appropriate code identifying the mold and cavity used. In instances where the manufacturer has more than one plant location or produces for other suppliers or distributors, an identifying symbol shall be used.


8.4 Thread compounds, sealants, gasket lubricants, solvent cement, and adhesives The manufacturer shall label each container with the designations and identifications required in the applicable standards as referenced in 2 of this Standard. The container shall bear an appropriate batch number identifying the day, month, and year of manufacture, as well as the formulation designation. In instances where the manufacturer has more than one plant location or produces for other suppliers or distributors, an identifying symbol shall be used. 8.5 Special engineered products

The manufacturer shall place the symbol "SE" on all special engineered products, in addition to the other applicable marking requirements specified in the SE specifications. 8.6 Ingredients The manufacturer shall place on all ingredient containers the manufacturer's name, trade designation, and lot number or date.

9 Quality assurance 9.1 General A quality control program shall be operated and maintained to ensure that products conform to the applicable requirements of this Standard on a continuous basis. a) The manufacturer shall provide and maintain quality control testing facilities at each production facility.

21

© 2013 NSF

NSF/ANSI 14 – 2012

b) Quality control testing shall be conducted at ambient temperature and humidity or standard laboratory conditions of 23 ± 2° C (73 ± 3.6° F) and 45 to 55% relative humidity. c) The tests and testing frequencies shall conform to the minimum requirements listed in 9.9. Where quality control requirements are specified in the product standards, the tests and test frequencies specified in the product standards shall be conducted in addition to the requirements listed in 9.9. If the test frequencies specified in the product standard conflict with the frequencies contained in 9.9, then the more frequent requirement shall be followed. d) SE products shall be tested in accordance with the quality control program specified in the SE Specifications. Variations from these minimum requirements shall be permitted if an alternate program is established in writing and determined to be equivalent. 9.2 Start-up and qualification of molds In each case, with the exception of annual and semi-annual tests, the frequency of testing indicated in 9.9 shall be interpreted as follows: the indicated tests shall be performed at the start-up of any production operation, on each extruder or injection molder, and continued until a steady-state operation that meets the test requirement is obtained. The test shall be repeated at the required frequency until there is a change in the steady-state operation. When there is a change in operation, testing shall be conducted continuously until a new steady-state operation is achieved. After a steady-state operation is attained, the applicable testing frequencies shown in 9.9 shall resume.


The test frequency indicated for fittings shall be used only after the mold has been qualified. In order for a new or retooled mold to be considered “qualified,” all products from all cavities in the mold shall attain compliance with all of the appropriate dimensions and tests. This does not include annual or semiannual tests. After qualification, the indicated test frequencies shall apply to one cavity per mold, rotating cavities within the mold, including start-ups. If any physical change is made to the mold itself, all cavities within the mold must be re-qualified. When annual testing is required, annual testing performed by a third-party certifier shall satisfy the requirement. 9.3 Generic ingredients

The quality assurance program shall ensure that each lot of generic ingredient complies with the requirements of 5.5. Records shall be maintained according to 9.5. 9.4 Verification of the calibration of equipment The calibration of all equipment used to check critical dimensions shall be verified weekly. Verification shall consist of checking the zero point, if applicable, and the critical dimension or a point near the upper limit of the instrument. Where applicable, references used for verification shall be traceable to the National Institute of Standards and Technology (NIST). Other equipment, including equipment used for measuring ingredients in in-plant blending operations, shall be verified at a minimum of once annually.

22

NSF/ANSI 14 – 2012

Records of equipment verification shall include the following: – – – – –

date that the verification was performed; identity of the equipment verified (description and serial number); verification data; description of any corrective actions taken, if applicable; and identity of the person who performed the verification.

9.5 Quality assurance records The manufacturer shall maintain records of quality assurance testing at each production location for at least three years. 9.6 Production code identification In instances where code identification of products is required, the manufacturer shall maintain records necessary to confirm identification of all products. 9.7 Number of test specimens Unless otherwise specified by an applicable standard as referenced in 2 of this Standard, the minimum number of test specimens for a sample of one size, style, configuration, and material shall be as indicated in table 2.


9.8 Formulation verification for solvent cements and primers

Formulation verification complying with the following conditions is permitted as a substitute for annual and one semiannual performance testing and health effects testing of solvent cements and primers. – performance testing and health effects testing of solvent cements and primers shall be conducted at least once every three years; – the analysis of the amount of solvent in solvent cements and primers shall be conducted according to table 3; and – depending on the percentage of solvent claimed on the label or in the formulation, the variation in the amount of solvent shall not exceed the control limits in table 4. 9.9 Product-specific quality assurance requirements Tables 5 through 33 provide product-specific quality assurance requirements.

Control limits for % change ± 15% of the solvent concentration (RPD) ± 3% of the total formulation (AD)

1

If the formulation concentration is expressed as a range, then the midpoint of the range shall be used in the calculation of the control limits for percent change. The following equations shall be used to determine compliance for solvent control limits: 20% ≤ FC ≤ 100%: RPD = ([test result – FC]/FC) x 100 0% ≤ FC < 20%: AD = test result – FC where: FC = formulation concentration RPD = relative percent difference between test result and FC AD = absolute difference between test result and FC
