The baffles were used alternately until the amounts ofgrease collected in the procedure are less than 1% by visual observation. Uponcompletion of the skimming procedure, water shall be drained from the bottom of thepail by means of a spigot.

3.5Rating Test Procedure :See Table 1 of test report for Rating Testing.3.5.1Test Media:FOLLOWEDCertification tests were conducted with fresh, unused lard and water as defined andboth within a temperature range from 150 F to 160 F.3.5.2Ratio of Lard to Water:FOLLOWEDThe test lard was introduced into one compartment, during each incrementaldischarge, in the ratio of 1 lb. of lard for each 5 gallons of water in that compartment.Consequently, the proportion of lard to the total amount of water discharged from bothsink compartments during each increment was 1 lb. for each 10 gallons respectively.The required amount of test lard, within the above temperature range, was weighedout and poured into the test compartment of the sink.Findings- 10 lbs per increment used.3.5.3Test Increments:3.5.3.1Each test increment consisted of the simultaneous discharge of water from both sinkcompartments and the lard from the test compartment.3.5.3.2During the first test increment, the lard was poured into compartment 1 whilecompartment 2 discharged clear water. During the second test increment the lard waspoured into compartment 2 while the water in compartment 1 remained clear.3.5.4Flow Rates:FOLLOWEDThe drainage period for each increment was gauged and timed on the basis of the flowfrom the compartment containing the clear water. The flow rate from the sink wascomputed and recorded for each increment. (See Table 1 of test report).3.5.5Efficiency Determinations:FOLLOWEDThe grease was removed from the skimming tank and the efficiency of the interceptorwas computed at intervals of five increments or less until the average efficiencyreached 93% or less and/or the incremental efficiency reached 85% or less (See Table1 of test report).3.5.6Duration of the Test:FOLLOWEDThe testing was continued until the average efficiency reached 85% or less and/or theincremental efficiency reached 75% or less.3.5.7Determination of Grease Retention Capacity:FOLLOWEDMaximum grease retention capacity was established at the increment preceding twosuccessive increments in which either the average efficiency is less than 90% or theincremental efficiency is less than 80 %.Report No. 1757-16008-002FOLLOWEDPage 7 of 10

hydrate (C–S–H), ettringite, and Ca(OH) 2 through a hydration reaction in which hydration heat is produced within the concrete because of an exothermic reaction. Since the thermal cracking of concrete reduces its internal force, watertightness, and durability, an appropriate measure is required to control the heat of hydration. The factors that influence the hydration heat of concrete .
