6.4 mm) and created by folding an unfiltered cigarette back upon itself such that the cigarette paper tears or breaks apart in approximately one-half lengths. Tap water shall be added to the unit at a flow rate of 1 pint (0.5 L) per min. Cigarette pieces and water shall be alternately added to the test urinal until a total of 20 cigarette pieces and 10 pints of water have been added. The cigarette pieces shall then be removed from the test urinal, and the test shall be conducted five additional times (for a total ofsixtestreplicates). Alternate between unfiltered and crumpled unfiltered cigarettes per test so that three tests are conducted using unfiltered cigarettes and three tests are conducted using crumpled unfiltered cigarettes.
6.3.2 Performance Requirement. There shall be no evidence of stoppage or clogging during each test run with cigarette pieces in the fixture and when removed.
6.4 Tightness Test of Removable Trap
6.4.1 Test Method. The trap insert shall be installed and removed 50 times using the extractor tool provided by the manufacturer. This shall be considered one repeti- tion. Upon completion of the extractions and insertions, the trapway shall be subjected to an air-pressure test at the trapway inlet of 1.45 psi (0.1 bar) for a minimum of 15 min. This test shall be repeated for a total of five repetitions of test sets (50 times each).
6.4.2 Performance Requirement. There shall be no pressure loss at any time during the test.
6.5 Evaluation Testing for Ammonia
6.5.1 Test Method
6.5.1.1 Selection ofthe Urinal-CleaningChemical. Function tests of the test urinal shall be conducted using the specific chemicals and/or cleaners recommended by the manufacturer. The chemical and/or cleaner shall be selected on a random basis from consumer-sized pack- ages provided by the manufacturer.
6.5.1.2 Test Enclosure Configuration and Urinal Mounting 6.5.1.2.1 The test urinal shall be installed in accordance with para. 6.2 within an enclosed area that is set aside for the test. A surround test enclosure shall be provided in a configuration that isolates the test uri- nal and test regions from laboratory space conditioning air motion, i.e., no draft air motion or exchanges that can disorderthe accuracyofthe sampling measurements shall be permitted. The test enclosure shall have a single entry door and suitable temperature control that main- tains an air temperature between 68°F and 100°F (20°C to 38°C). The door is required to allow entry and exit of personnel for installation of the test urinal and required test instrumentation and conduct of the test, including the monitoring of test instrumentation.
6.5.1.2.2 The enclosure size shall be approxi- mately that of two telephone booths and provide for mounting of and sampling at the test urinal. The enclo- sure may either be comprised of prefabricated panels for assembly and storage while not in use or, alternatively, a permanent enclosure. The size of the enclosure shall allow for a person of no fewer than 6 ft in height to stand erect within the enclosure. Other dimensions of length and width shall be at the discretion of the testing laboratory but shall allow for the mounting of the test urinal in a manner consistent with the provisions of the applicable plumbing codes. The test urinal, with the required elements of support, shall be mounted at the vertical centerline of a wall panel in the enclosure at a height from the floor as specified by the manufacturer or applicable plumbing code. Adjacent distances to the side walls from the installed test urinal shall be a mini- mum dimension as specified in the applicable plumbing code for adjacent urinals or walls.
6.5.1.2.3 Discharges of test liquids from the test urinal may either be collected through installed pipe fittings connected to the laboratory drainage system or, alternatively, by other means, such as collection in a tank or similar vessel, the method to be chosen at the discretion of the laboratory.
6.5.1.3 Test Set-Up. The test enclosure shall be located so as to be isolated from disturbances. A maxi- mum-minimum and current temperature recording and indicating instrument shall be installed 1 ft (0.3 m) ± 2 in. (50 mm) above and to the right of the test urinal on a support other than the test urinal.
6.5.1.4 Test Equipment. Testequipmentto be used for the evaluation testing shall be the following or an equivalent:
