The markingshall be visible after installation.2.6 Labeling2.6.1 Compliance with standard. Each fixture shall bemarked at a location determined by the manufac

39、turer with thedesignation ANSI Z124.9 to signify compliance with thisstandard. This mark need not be permanent, but shall be visibleafter installation.2.6.2 Water consumption. Water fed urinals, both boxand product, shall be marked as required in ASME/ANSIA112.19.2M. The fixture label shall be inten

The unit shall be installed according tomanufacturers installation instructions so as to simulateconditions of permanent installation, excluding fittings andpiping.3.2 Methods of inspection of the unit surface. The urinal shallbe examined for min

Minor blemishes not observedin this procedure are assumed to be unseen surfaces.3.3 Surface characteristics3.3.1 Test method.1The unit shall be washed withstandard liquid detergent2and water solution, rinsed with clearwater and dried. The surface of the unit shall then be rub

46、bedwith a sponge and a 50% solution of tap water and watersoluble black or blueblack ink. The ink shall be rinsed from thesurface of the unit and dried before inspecting for defects orblemishes. When inspecting colored units, a contrasting coloredink shall be used.3.3.2 Performance requirement. The

47、units shall be freefrom cracks, chipped areas, blisters and large specks (largerthan 1/16 inch) (1.6 mm). See definitions under Table 1. Thenumber and size of molding irregularities and certain otherdefects and blemishes shall not exceed those given in Table 1.3.4 Subsurface porosity3.4.1 Test metho

48、d. Any finish surface suspected of havingsubsurface porosity shall be subjected to the standard dirt test.Two areas of the unit approximately 10 square inches (64.5cm2) each, shall be conditioned by rubbing these areas for 25cycles with 600 grit wet silicon carbide abrasive paper.3Onearea shall be l
