Summary of Test Methods6.1 Particle size distribution is achieved using Test MethodC136, which provides a test method for determining particlesize distribution by passing a sample of known mass through aseries of sieves of progressively smaller

33、 openings.6.2 Loose-fill rubber hazardous metal content is determinedusing a procedure contained in Specification F963. Thisprocedure simulates the situation in which loose-fill rubberremains in the digestive tract for 4 h after swallowing byextracting soluble hazardous metals from the loose-fill ru

34、bbersample with an acidic solution. The resultant solution is thenanalyzed for mercury content using EPA Method 7470A. Thecontent of the balance of the hazardous metals is analyzedusing EPA Method 6010B.6.3 The presence of tramp metal in the loose-fill rubber isdetermined by visual inspection as wel

35、l as by collecting anyferrous tramp metal particles from the loose-fill rubber sampleusing a Ceramic Grade 8 hand magnet. Tramp metal is testedfor sharpness according to the procedure in 16 CFR 1500.48.6.4 Total lead content of the loose-fill rubber sample isdetermined by strong acid digestion using

36、 EPA Method 3050Bor 3051A, followed by instrumental analysis of the resultantdigestate using one of the test methods specified in ASTME1613.TEST METHODS7. Sieve Analysis Test Method7.1 Significance and UseThis test method is used todetermine the particle size distribution of loose-fill rubber toinsu

37、re that the material tested has a particle size distributionthat is appropriate for use as a playground surface. Thespecified particle size distribution is one that provides sufficientporosity for drainage and limits compaction to allow for properresilience.7.2 Apparatus:7.2.1 BalancesBalances or sc

38、ales used in testing fine orcoarse aggregate shall be readable and accurate to the greaterof 0.018 oz (0.5 g) or 0.1 % of test load at any point within therange of use.7.2.2 Sieves:7.2.2.1 The sieve cloth shall be mounted on substantialframes constructed in a manner that will prevent loss ofmaterial

39、 during sieving. The sieve cloth and standard sieveframes shall conform to the requirements of Specification E11.Nonstandard sieve frames shall conform to the requirements ofSpecification E11, as applicable.7.2.2.2 Sieve sizes required are: for nuggets;78 in. and No.4(316-in. (4.8-mm) sieves, and fo

40、r buffings; one in., No. 5, No.8, and No. 16 sieves; mounted on a standard frame 8 in. (20cm) in diameter and 2 in. (5 cm) high.7.2.3 Sieve ShakerA mechanical sieving device, if used,shall create motion of the sieves to cause the particles tobounce, tumble, or otherwise turn so as to present differe

41、ntorientations to the sieving surface. The sieving action shall besuch that the criterion of adequacy of sieving described in thistest procedure is met in a reasonable time period.7.2.4 OvenThe oven used for drying the sample shall beof a size capable of accommodating a 1-dry gal (4.4-L) sampleand b

42、e capable of maintaining a uniform temperature of 140 69F (60 6 5C).7.3 Sample Preparation:7.3.1 From the 20-dry gal (88-L) sample of loose-fill rubber,measure a 1-dry gal (4.4-L) sample for drying followed bysieve testing.7.3.2 Oven dry the 1-dry gal (4.4-L) test sample to aconstant weight using an

43、 oven temperature of 140 6 9F (60 612.7C). (A constant moisture level is necessary to preventweight changes because of changing moisture levels in thesample.)7.4 Procedure:7.4.1 Nest the sieves in order of decreasing size of openingfrom top to bottom and place the sample on the top sieve.7.4.2 Agita

44、te the sieve by hand or mechanical apparatus fora sufficient period, established by trial or checked by measure-ment on the actual test sample, to meet the criterion foradequacy of sieving described in 7.4.5.7.4.3 Limit the quantity of material on the sieve so that allparticles have the opportunity

45、to reach sieve openings anumber of times during the sieving operation.7.4.4 Prevent an overload of material on the individual sieveby one of the following methods:7.4.4.1 Insert an additional sieve with an opening sizeintermediate between the sieve that is overloaded and the sieveimmediately above t

46、hat sieve in the original set of sieves.7.4.4.2 Split the sample into two or more portions, sievingeach portion individually. Combine the masses of the generalportions retained on a specific sieve before calculating thepercentage of the sample on the sieve.7.4.5 Continue sieving for a sufficient per

47、iod and in such amanner that, after completion, not more than one mass percentof the residue on any individual sieve will pass that sieveduring 1 min of continuous hand sieving as follows: hold theindividual sieve provided with a snug-fitting pan and cover ina slightly inclined position in one hand.

48、 Strike the side of thesieve sharply and with an upward motion against the heel of theTABLE 3 Maximum Allowable Soluble Concentration in mg/LAntimony(Sb)Arsenic(As)Barium(Ba)Cadmium(Cd)Chromium(Cr)Lead(Pb)Mercury(Hg)Selenium(Se)60 25 1000 75 60 90 60 500F3012 143other hand at a rate of about 150 tim

49、es per minute, turning thesieve about one sixth of a revolution at intervals of about 25strokes. In determining the sufficiency of sieving for sizeslarger than the No. 16 sieve, limit the material on the sieve toa single set of particles. If the size of the mounted testing sievesmakes the described sieving motion impractical, use 8-in.(20-cm) diameter sieves to verify the sufficiency of sieving.7.4.6 Hand sieve larger particles by determining the small-est sieve opening through which each particle will pass. Startthe test on the smallest sieve to be
