1、Designation:D452/D452M19Standard Test Method forSieve Analysis of Surfacing for Asphalt Roofing Products1This standard is issued under the fixed designation D452/D452M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last
2、revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the determination of the particlesize distribution of surfacing material,other than mineralgranules,suc
3、h as sand,mica,talc,or other powdered or flakymineral particles,used on both sides of“smooth”roll roofingand on the reverse side of asphalt shingles and mineral-surfaced roll roofing.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stat
4、ed ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is
5、 theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principles on stand

7、and TestSieves3.Summary of Test Method3.1 A weighed sample of surfacing material is separatedthrough a series of sieves of progressively smaller openings forthe determination with particle size distribution.4.Significance and Use4.1 This test method is used to determine the grading ofmaterials used
8、as surfacing.The results are used to determinecompliance of the particle size distribution with applicablespecification requirements.5.Apparatus5.1 SievesAset of the sieves listed in Table 1,conformingto Specification E11.For routine testing,the group of sievesactually used shall include only those
9、appropriate for thematerial being graded.Coarser or finer sieves,on which lessthan 0.05 mass%of the specimen would be found aftersieving,need not be included in the group.NOTE1For relatively coarse or flaky materials,such as coarse mica,sieves from 1.18-mm to 212-m(Nos.16 to 70)inclusive,will usuall
10、y befound suitable.For finer surfacing materials,such as fine mica or talcflour,sieves from 600 to 75-m(Nos.30 to 200)inclusive,will usuallygive a satisfactory sieve analysis.5.2 Sieve ShakerA mechanically operated sieve shaker,which produces a uniform rotary motion and tapping actionwith 140 to 160
11、 taps per minute.The sieve shaker shall be fittedwith a hard maple plug to receive the impact of the tappingdevice.The plug shall be one of the following:a hard mapleplug;a#9 Black Rubber Plug;or a#22 cork plug as chosen bythe user.Plug dimensions are:Top Diameter 44 6 1 mm,Bottom Diameter 37 6 1 mm
12、,and Length of 38 6 6 mm.SeeNote 2.The entire apparatus shall be rigidly mounted bybolting to a solid foundation,preferably concrete.NOTE2Supporting data on the equivalency of the plug materials isgiven in Appendix X1.5.3 Sample SplitterThe riffle sample splitter is an openV-shaped box in which a se
13、ries of chutes is mounted at rightangles to the long axis to give a series of rectangular slots ofequal area alternatively feeding two trays placed on either sideof the trough.The sample is poured into the chute and split intoequal portions by the slots,until,after repeated cycles,asample of the des
14、ired size is obtained.A riffle sampler with 9.5or 12.7-mm 38or12-in.divisions shall be used for reducingthe sample to the specimen required for sieve analysis.5.4 Oven,capable of maintaining 105C 221F.NOTE3Supporting data on the equivalency of the plug materials isgiven in Appendix X1.1This test met
