3.2.2 Grease Delivery System (Grease Metering Sink. A floor sink of sufficient volume to contain 10% of the rated grease capacity of the GRD being tested shall be connected through a ball valve to the horiiontal line between the base of the vertical waste riser IASME Al 12.14.3. para. 3.2.l.44d)I and the GRD inlet (See Fig. I). This floor sink shall be used to meter grease into the GRD.
3.2.3 Test Materials. Lard, as required in ASMF. A 112.14.3. shall be uscd to conduct this test.
3.3 GRD Conditioning
Prior to starting the test increments. the GRD shall be cleaned of all grease from previous tests and filled with fresh water to the static water level. The water shall be at a temperature of 70±10°F (21±6°C). All electronic and mechanical components shall be set as described in the manufacturer’s instructions for normal operation.
3.4 Grease Removal Test
3.4.1 The rated retention capacity of the GRD submitted for test shall he determined in accordance with
ASMI A1l2.14.3.
3.4.2 During the test, warer at I 10±5°F (43±3°C) shall be introduced to maintain static water level within the GRD during continuous operation in accordance with the manufacturer’s instructions.
3.4.3 All GRD controls shall be set in accordance with .nanut.icttirer’s instructions.
3.5 Accept/Reject Criteria
3.5.1 After completion of the removal test, the volume of grease removed by the CRD shall be not less than 50% of its rated capacity.
3.5.2 During the test interval, at no rime shall accumulated grease within the GRD exceed its rated retention capacity.
3.2.3 Test Materials. Lard, as required in ASMF. A 112.14.3. shall be uscd to conduct this test.
