8 Marking requirements 8.1 General Markings on plastic piping system components shall be legible and permanent. 8.2 Pipe The manufacturer shall place on all plastic pipe the designations and identifications required in the applicable standards as referenced in 2 of this Standard or as required by the SE Specification. Plastic pipe shall also bear an appropriate code identifying the day, month, and year of production, the extrusion line, and the compound designation. 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.

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.

Table 4 – Solvent control limits

Solvent concentration ranges on formulation1 Control limits for % change ≥ 20% to ≤ 100% ± 15% of the solvent concentration (RPD) ≥ 0%2 to < 20% ± 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

2 This includes the presence of solvents detected because of change-over contamination that are not intended to be present in the formulation, limited to acetone, cyclohexanone, methyl ethyl ketone, and tetrahydrofuran.

Table 31 – Quality assurance requirements for materials suppliers and

special compounders1

Cell classification verification – material suppliers and special compounders Material suppliers and special compounders shall check their manufactured and blended materials for all of the parameters in the cell classification on a semiannual basis (twice per year).2 Records of the test data shall be maintained at each production facility. Lot-by-lot quality control – material suppliers The following tests shall be performed on each lot produced. Records of the test results shall be maintained at each production facility. RVCM (PVC/CPVC compound for potable water application) For CPVC, RVCM analysis shall be performed either on the PVC resin prior to chlorination or on the finished CPVC compound. In either case, the maximum permissible level is 3.2 mg/kg. 1 Cross-linked polyethylene (PEX) materials are excluded from evaluation according to this table since cell classification parameters do not exist. 2 The HDB requirement is excluded since it is a qualification test.
