Sieve Test Analysis Method7.1 Significance and Use:7.1.1 Sieve AnalysisThis test method is used to determinegradi

39、ng of engineered wood fiber-type material for proposeduse as an engineered wood fiber playground safety surface. Theresults are used to determine compliance of the particle sizedistribution with applicable specification requirements and toprovide necessary data that will indicate sufficient porosity

40、 fordrainage, and larger particle size to limit compaction andmaintain resilience and limit oversize pieces that could causeinjury.7.2 Test Apparatus:7.2.1 BalancesBalances or scales used in testing fine andcoarse aggregate shall be readable and accurate to 0.5 g or0.1 % of the test load, whichever

41、is greater, at any point withinthe range of use.7.2.2 SievesThe sieve cloth shall be mounted on substan-tial frames constructed in a manner that will prevent loss ofmaterial during sieving. The sieve cloth and standard sieveframes shall conform to the requirements of Specification E11.Nonstandard si

42、eve frames shall conform to the requirements ofSpecification E11as applicable.7.2.2.1 Sieve sizes required:34 in. (19.05 mm),38 in. (9.53mm) and No. 16, 0.0469 in. (1.19 mm), mounted on standardframe 8 in. (203.20 mm) diameter 2 in. (50.8 mm) height.7.2.3 Sieve ShakerA mechanical sieving device, if

43、used,shall create motion of the sieves to cause the particles tobounce, tumble, or otherwise turn so as to present differentorientations to the sieving surface.

45、ncewith the following method. (A constant moisture level isnecessary to prevent weight changes due to changing moisturelevels in the sample).7.3.3 The wood fiber sample was reduced in overall size tofacilitate testing using a standard 2-in.-deep 8-in.-diametersieve. Because of the light weight of wo

46、od fiber, the oven driedsample weight of individual samples to be tested should notgenerally exceed 0.40 lbs (181 g). Sieve screens, sieve frames,and wire cloth should conform to the requirements of Specifi-cation E11. Samples should be oven dried to a constant weightin general accordance with Pract

47、ice D 2217 for oven drying ofsamples following reduction of the mass (oven temperature of140F and accuracy to 69F (60 6 5C).7.4 Test Preparation for Sieve Analysis:7.4.1 Because of the irregular shapes of the wood particles,hand manipulation of the sample through the sieve screens maybe necessary.7.
