Designation:C133512Standard Test Method forMeasuring Non-Fibrous Content of Man-Made Rock andSlag Mineral Fiber Insulation1This standard is issued under the fixed designation C1335;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers a procedure for determining thenon-fibrous content(shot)of man-made rock and slag mineralfiber insulation.The procedure covers a dry sieve analysismethod to distinguish between fiberized and non-fiberized(shot)portions of a specimen of man-made rock and slagmineral fiber insulation specimen.1.2 This test method does not apply to rock or slag materialscontaining any components other than rock and slag mineralfiber and organic thermal setting binders.Products containingother types of fibers,inorganic binders,or refractory clays areexcluded.1.3 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C168 Terminology Relating to Thermal InsulationC390 Practice for Sampling and Acceptance of ThermalInsulation LotsE11 Specification for Woven Wire Test Sieve Cloth and TestSievesE178 Practice for Dealing With Outlying ObservationsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test Method3.Terminology3.1 DefinitionsTerminology C168 shall be considered asapplying to the terms used in this test method.3.2 Definitions of Terms Specific to This Standard:3.2.1 shotmaterial that cannot be brushed or mechanicallyshaken through a No.100(150 m)sieve.4.Significance and Use4.1 Inorganic fibrous thermal insulation can contain varyingamounts of non-fibrous material.Non-fibrous material does notcontribute to the insulating value of the insulation and thereforea procedure for determining that amount is desirable.Severalspecifications refer to shot content and percent(%)retained onvarious screen sizes determined by this test method.5.Apparatus5.1 Furnace,capable of maintaining 1100 6 10F(593 65.6C)for rock and slag wool.5.2 U.S.A.Standard Sieve Shaker Machine.5.3 Balance Scale,capable of weighing to an accuracy of0.00035 oz(0.01 g).5.4 SievesThree 8 in.(203 mm)diameter U.S.A.StandardSieves.Nos.20(850 m),50(300 m),and 100(150 m)nested in order with bottom receiver pan.All sieve design andconstruction shall be in accordance with Specification E11.5.5 BrushApproximately 1 in.(25 mm)diameter plasticbristle brush,and approximately 1 in.(25 mm)wide soft paintbrush.5.6 Crucible Weighing Dish,tared.5.7 Stoppers,rubber,No.12 or 13.5.8 Cork Borer,approximately 0.8 in.(20 mm)diameter.6.Sampling and Preparation of Test Specimen6.1 For the purposes of standard tests,sampling shall be inaccordance with Practice C390 and Practice E178 with aminimum of three specimens per lot to be tested.6.1.1 SpecimenThis test method requires approximately a0.35 oz(10 g)specimen.6.2 Specimen Preparation:1This test method is under the jurisdiction ofASTM Committee C16 on ThermalInsulation and is the direct responsibility of Subcommittee C16.32 on MechanicalProperties.Current edition approved May 1,2012.Published July 2012.Originally approvedin 1996.Last previous edition approved in 2009 as C1335 04(2009).DOI:10.1520/C1335-12.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 6.2.1 Obtain a representative specimen utilizing a 0.8 in.(20mm)cork borer for blanket or board and random specimens forloose fill.Fire the specimen in a tared dish at 1100 6 10F(5936 5.6C)for 15 min.Remove tared dish with specimen andallow to cool for approximately 20 min.6.2.2 Weigh the crucible weighing dish and fiber on balancescale to the nearest 0.00035 oz(0.01 g),subtract tare dishweight,noting the mass of specimen after firing as WT.7.Procedures7.1 ShotFiber Separation Procedure A(Includes ShakerMachine):7.1.1 Assemble a nest of sieves(Nos.20,50,and 100)starting with a cover and the coarsest sieve on the top and a panon the bottom.7.1.2 Place the specimen on the top sieve with receiver(s)inplace.7.1.3 With the plastic bristle brush or rubber stopper,brushto brake-up the specimen through the N
