1、Designation: C 1335 04Standard Test Method forMeasuring Non-Fibrous Content of Man-Made Rock andSlag Mineral Fiber Insulation1This standard is issued under the fixed designation C 1335; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revisio

2、n, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) 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

3、 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 compon

4、ents 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 the standard. The values given in parentheses are forinformation

5、 only.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. Refere

15、 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 weighin

16、g 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

17、 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 No. 20 sieve.7.1.4 Deposit one rubber stopper on each sieve screenbefore final assemb

18、ly.7.1.5 Place the entire nested sieve-assembly with specimenon the motor-driven testing sieve shaker and operate theautomatic shaker-hammer for 20 min or until all fibrousmaterials are passed through to the pan.7.1.6 Carefully remove all material retained on each sieveand weigh individually (withou

19、t sieve and stopper) on thebalance pan.7.1.6.1 Weigh the material retained on each sieve to thenearest 0.00035 oz (0.01 g).7.2 ShotFiber Separation Procedure B (Manual Opera-tion):7.2.1 Place the specimen on the top sieve with receivers inplace.7.2.2 With the plastic bristle brush or rubber stopper,

20、 brushthe specimen through the No. 20 and No. 50 sieves.7.2.3 With the soft paint brush, brush the specimen throughthe No. 100 sieve. On all sieves, be certain that all fibrousmaterial is brushed through.7.2.4 Carefully remove all material retained on each sieveand weigh individually (without sieve)

21、 on the balance pan.7.2.4.1 Weigh the material retained on each sieve to thenearest 0.00035 oz (0.01 g).8. Calculation8.1 Calculate the percentage of non-fibrous material for onespecimen retained on the No. 20 sieve, No. 50 sieve, and No.100 sieve, respectively.8.1.1 Add the No. 20 sieve plus No. 50

22、 sieve plus No. 100sieve masses together noting as WP and calculate as follows:WC 5WP 100!WTwhere:WC = % mass of non-fibrous material for one specimen,WP = mass of material on all sieves, andWT = mass of specimen after firing.8.2 Adding the total percentages of all WC (s) (minimum ofthree specimens/

23、tests) and dividing by the number of WC (s)equals the average total percent of shot (shot content).9. Report9.1 Report the following information:9.1.1 A description of the material being tested, includingspecimen source (company name and manufacturing location),color, production code, or any other i

24、nformation that will helpidentify specimen.9.2 The percentage by weight retained for each sieve size, aswell as the total percent non-fibrous material (shot content) tothe nearest tenth of a percent. The total percentage shot contentwill be reported for the average of at least three separatespecimen

25、 results in accordance with 6.1.9.3 The temperature at which the material was fired and thetime the U.S.A. Standard Sieve Shaker Machine was operated.10. Precision and Bias10.1 Precision The test results for representation of per-formance of the material will depend on the variability of thematerial

26、, plus sampling and specimen preparation.10.1.1 The results were evaluated using Practice E 691.Repeatability and reproducibility are herein defined as 2.8times the corresponding standard deviation to obtain a 95%confidence level. Repeatability is the variability between testresults within each labo

27、ratory, and reproducibility is thevariability between test results from different laboratories.10.1.2 Interlaboratory tests The results of interlaboratorytests conducted in 2003 for Total Shot using procedures “A”and “B” are listed in Table 1 and Table 2. The interlaboratorytests were conducted in a

28、ccordance with Practice E 691 withexception of the minimum number of test laboratories were notmet. The study involved five different materials (specimens)from five different manufacturing facilities with three repli-cates of each specimen.10.2 BiasNo statement of bias can be made for this testmetho
