An aluminum disk 150 ± 6 mm (6 ±.25 in.) in diameter and 7 ± 1 mm (1/4 ± 1/32 in.) thick shall be heated for 15 ± 0.5 minutes in an oven maintained at 185 ± 5 C (365 ± 10 F) shall be placed on the test area and allowed to remain for 10 ± 0.5 minutes, after which it shall be removed. This procedure shall be repeated two more times (for a total of three times) on the same test area. The sink shall then be allowed to remain at room ambient temperature for four hours and shall be inspected for any surface deterioration such as cracking, crazing, discoloration, or other surface defects Performance requirement. There shall be no cracking, crazing, or blistering. Any discoloration shall be removable using abrasives and polishing compound to approximate the original finish and serviceability. In case of conflict, examination shall be made by the method of ASTM D2244, and the average color difference E shall be no more than 2, after abrading and polishing, shall be no more than ± 2 CIE units. 5.7 Hot wax test. (kitchen sinks only) Test method. The following test shall be performed on each sink compartment with the outlet open and repeated with the outlet closed. 296 ± 50 ml (10 ± 1 fluid ounces) of bath wax 2827 heated to 185 ± 5 C (365 ± 10 F) shall be poured onto the bottom of the compartment at a point furthermost from the waste outlet. The time of pouring shall be 5 ± 1 seconds. The sink shall then be allowed to remain at ambient temperature for 30 ± 5 minutes and shall be inspected for any surface deterioration such as cracking, crazing, discoloration, or other surface defects. approximate the original finish and serviceability. In case of conflict, examination shall be made by the method of ASTM D2244, and the average color difference, after abrading and polishing, shall be no more than ± 2 CIE units. 6. Additional material tests 6.1 Thermal shock resistance test. (kitchen, laundry and service sinks only) Test method. Impinge a water stream on the bowl surface 1-1/2 inches from the edge of the drain hole water at 88 ± 2 C (190 ± 3 F) for 1.5 minutes followed immediately at the same point with cold water at 21 ± 2 C (70 ± 3 F) for 1.5 minutes. Tests shall continue for 250 consecutive cycles without pause between cycles at water flows of ± 0.8 L/minute (1 ± 0.2 gallons/minute) Performance requirement. No cracking, crazing, blistering, pealing, or delamination shall be permissible. Inspection for cracking and crazing shall be made using an ink solution as described in Section Thermal shock resistance test (bar sinks only) Test method. Impinge, on bar sink surface, where water will normally strike, water at 65.5 ± 1.6 C (150 ± 3 F) for 1.5 minutes. Allow water to drain for 30 seconds. Follow immediately at the same point with cold water at 10 ± 1.6 C (50 ± 3 F) for 1.5 minutes. Allow water to drain for 30 seconds. This shall constitute one complete cycle. Continue test for a total of 500 cycles. Flow rates shall be ±.013 L/s (1 ± 0.2 gpm) Performance requirement. There shall be no cracking, crazing, blistering or spalling; or delamination. Inspection for cracking and crazing shall be made using an ink solution as described in Section Provisions for Government Procurement When required by Government procurement documents, the information defined in Appendix II shall be specified by the purchasers. 21 Winston, Kent and Marlboro cigarettes were used for this test. 22 Varnish makers & painters naphtha was used in preparing this test. 23 Clorox was used in preparing this test. 24 Lysol was used in preparing this test Drano was used in preparing this test Heinz Diluted White Vinegar was used in preparing this test Pine Sol Cleaner Disinfectant was used in preparing this test Fisher Scientific Co.

19 II.4 QUALITY ASSURANCE PROVISIONS AMERICAN NATIONAL STANDARD IAPMO/ANSI Z II.4.1 Responsibility For Inspection. The contractor shall be responsible for the performance of all inspection requirements as specified herein. The contractor may use his own or any other facilities suitable for the performance of the inspection requirements unless disapproved by the Government. The Government reserves the right to perform any of the inspections set forth in the standard where such inspections are deemed necessary to assure supplies and services conform to prescribed requirements. II.4.2 Quality Conformance Inspection. Where specified (see II.6), a quality conformance inspection shall be performed on each sample selected (see II.4.3) to determine compliance with this standard and shall include the following: A. Examination. This element of inspection shall encompass all visual examination and dimensional measurements. Non-compliance with any specified requirements shall constitute one defect. Examination shall be based on inspection level S-4 and Acceptable Quality Level (AQL) of 2.5 percent defective. B. Test. Each sampled fixture shall be tested in accordance with the applicable performance tests in this standard. Failure to pass any test constitutes one defect. Test shall be based on inspection level S-2 and an AQL of 4.0 percent defective. C. Preparation for delivery. Preparation for delivery shall be inspected for compliance with the requirements of Section II.5. II.4.3 Sampling. Sampling and inspection procedures shall be in accordance with ANSI Z1.4. The unit of product shall be one complete fixture. All fixtures of the same description offered for delivery at one time shall be considered a lot for the purpose of inspection. If an inspection lot is rejected, the contractor may rework it to correct the defects, or screen out the defective units, and resubmit for a complete inspection. Resubmitted lots shall be reinspected using tightened inspection. If the rejected lot was screened, reinspection shall be limited to the defect causing rejection. If the lot was reprocessed, reinspection shall be performed for all defects. Rejected lots shall be separate from new lots, and shall be clearly identified as reinspected lots. II.5 PREPARATION FOR DELIVERY The packaging, packing, and marking shall be as specified in the contract or purchase order (see II.6). II.6 ORDERING DATA Acquisition documents shall specify the following: a. Title, number and date of this standard. b. PIN designation (see II.3.1). c. Size code X as specified (See II d). d. Splashback height (See II f). e. Color (See II j). f. When a quality conformance inspection is required (see II.4.2). g. Preparation for delivery (See II.5) 19

20 AMERICAN NATIONAL STANDARD IAPMO/ANSI Z APPENDIX III (Non Mandatory) III1 Flame Spread and Smoke Density Tests 1. When information is desired by regulatory organizations to describe or specify the properties of materials used in plastic plumbing fixtures in response to heat and flame, the following optional test methods have been found to provide the most meaningful data for comparative purposes. However, these tests, run under controlled conditions, are not intended to appraise fire hazards or fire conditions, but they may be considered as elements of a fire risk assessment, which takes into account all of the factors which are pertinent to an assessment of fire hazard of a particular structure in which the product is used. III.1 Test Method. Units with an area of eight square feet (length x width of top surface) or more shall be tested by an independent laboratory using the test methods specified for each option in Table III. The option shall be selected by the manufacturer. When various products are made of the same materials, of the same nominal thickness of finished and supporting surfaces and by the same process by multiple manufacturers, only one test per variation shall be required. III.2 Performance Requirement. A flame spread rating of 200 or less and a smoke density or smoke generation rating of 450 or less shall be required. (See Footnote). Building codes may have other requirements for special occupancies such as medical facilities, nursing homes multi-story lodging facilities and residences and similar installations.
