4.1.2 Performance requirements. There shall be no visible cracks in the unit interior surface when inspected with the load in place after again inking as dcscnbcd in 3.3.1.
4.2 Impact tests
4.2.1 Point impact (all sinks)
4.2.1.1 Test method. A 38.1 mm (1-1/2 in) diameter,
0.225 kg (1/2 lb.) steel ball shall be dropped from a height of
610 mm (24 in.) to impact once on each of four different areas in each sink compartment. Two of these areas shall be on the flat area of the sink bottom, and the other two points shall be on the convex rim radius. Service sinks without rolled rims shall be impacted only on the compartment bottom. The ball shall be free of deformation, dents, gouges or other surface defects. Test locations for typical sink configurations shall be as shown in Figure 3. Additionally, the 0.225 kg (1/2 lb.) steel ball shall be dropped to impact once on each of three different points on flat areas of units with tops or integral tops and drainboards.
4.2.1.2 Performance requirement. The unit shall not show any cracks or chips after inking as described in 3.3.1.
4.2.2 Knife drop test. (kitchen and bar sinks only)
4.2.2.1 Test method. A 28.3 gram. (1 oz) steel knife
1.27 ± 0.127 mm (0.050 ± 0.005 in.) thick with a 6.6 ± 0.4 mm (1/4 ± 1/64 in.) radius rounded tip with the edge ground to 0.635 ± 0.051 mm (0.025 ± 0.002 in.) shall be dropped, tip down, from a height of 610 mm (24 in.) to strike two different points of the bottom of each compartment.
4.2.2.2 Performance requirement. After inspecting for damage by inking in accordance with Section 3.3.1, the unit shall not show any cracks or fractures. Any damage shall not extend through the surface finish and shall be restorable to approximate the original finish by using abrasives and polishing compounds.
4.2.3 Skillet drop test. (kitchen sinks only)
4.2.3.1 Test method. A 26.7 cm. (10-1/2 in) diameter cast iron skillet weighing 2 ± 0.04 kg (4.5 ± . 1 lbs.) shall be held with the handle up and dropped on two points (See Figure 3) between the drain and side wall from a height of 305 mm (12 in.) in each compartment approximately 90° apart.
4.2.3.2 Performance requirement. After inspecting for damage by inking in accordance with Section 3.3.1. the unit shall not show any cracks or fractures.
4.3 Load test. (kitchen, service, and laundry sinks only)
4.3.1 Test method. A preload weight of9l ± 2 kg (200
± 3 lbs.) shall be applied to the center of the bottom of the unit on a weight distribution disk 76.2 mm (3 in.) in diameter covered by a 13 mm (1/2 in.) thickness of sponge rubber or other suitable soft material between the disk and the surface being loaded. Leave the load in place for 2 to 3 minutes to allow for settlement of the test frame and any initial sup in fasteners. Ten to 15 minutes after removing the preload. reapply the 91 kg (200 lb.) load for Ito 2 minutes.
4.3.2 Performance requirements. Following the test described in 4.3.1. there shall be no cracks in the surface of the unit when inspected after again inking as described in
3.3.1. The maximum residual deflection 10 minutes after removal of the load shall not exceed 0.25 mm (0.010 in.).
4.4 Vibration test. This test shall be performed only on sink compartments with an outlet of 89 mm (3-1/2 inches) diameter or greater.
4.4.1 Test method. A food waste grinder6 shall be modifIed to create an imbalance in the grinder by adding a 15 gram (0.53 oz.) weight to one of the blades, or the disk, at a radius of 129 ± 3 mm (2-1/4 ± 1/8 in.). The overall weight of the grinder shall be 8.6 ± .23 kg (19 ± 1/2 lbs) and the center of gravity shall be 210 ± 6 mm (8-1/4 ± 1/4 in.) below the under side of the outer rim of a 114mm (4-1/2 in.) diameter mounting flange. The grinder shall then be assembled and attached to the sink assembly so that the electrical and waste water connections do not restrict the motion of the grinder. Cold water shall he flowing through the food waste grinder at a minimum of 3.8 liters (1 gallon) per minute during the test. The grinder shall be switched “on” for 30 seconds and “oil’ for 1 minute to complete one cycle. A total of 1000 cycles shall he conducted. After the total cycles, the sink shall be inked as per 3.3.1 and inspected.
4.4.2 Performance requirement. The unit shall not show any signs of cracks or fractures.
