ASTM C1335-12(2017)

Standard Test Method for Measuring Non-Fibrous Content of Man-Made Rock and Slag Mineral Fiber Insulation

SIGNIFICANCE AND USE
4.1 Inorganic fibrous thermal insulation can contain varying amounts of non-fibrous material. Non-fibrous material does not contribute to the insulating value of the insulation and therefore a procedure for determining that amount is desirable. Several specifications refer to shot content and percent (%) retained on various screen sizes determined by this test method.
SCOPE
1.1 This test method covers a procedure for determining the non-fibrous content (shot) of man-made rock and slag mineral fiber insulation. The procedure covers a dry sieve analysis method to distinguish between fiberized and non-fiberized (shot) portions of a specimen of man-made rock and slag mineral fiber insulation specimen.  
1.2 This test method does not apply to rock or slag materials containing any components other than rock and slag mineral fiber and organic thermal setting binders. Products containing other types of fibers, inorganic binders, or refractory clays are excluded.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

6.2.1 Obtain a representative specimen utilizing a 0.8 in. (20 mm) cork borer for blanket or board and random specimens for
loose fill. Fire the specimen in a tared dish at 1100 6 10°F (593 6 5.6°C) for 15 min. Remove tared dish with specimen and allow
to cool for approximately 20 min.
6.2.2 Weigh the crucible weighing dish and fiber on balance scale to the nearest 0.00035 oz (0.01 g), subtract tare dish weight,
noting the mass of specimen after firing as WT.
7. Procedures
7.1 Shot–Fiber Separation Procedure A (Includes Shaker Machine):
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 pan on the
bottom.
7.1.2 Place the specimen on the top sieve with receiver(s) in place.
7.1.3 With the plastic bristle brush or rubber stopper, brush to brake-up the specimen through the No. 20 sieve.
7.1.4 Deposit one rubber stopper on each sieve screen before final assembly.
7.1.5 Place the entire nested sieve-assembly with specimen on the motor-driven testing sieve shaker and operate the automatic
shaker-hammer for 20 min or until all fibrous materials are passed through to the pan.
7.1.6 Carefully remove all material retained on each sieve and weigh individually (without sieve and stopper) on the balance
pan.
7.1.6.1 Weigh the material retained on each sieve to the nearest 0.00035 oz (0.01 g).
7.2 Shot–Fiber Separation Procedure B (Manual Operation):
7.2.1 Place the specimen on the top sieve with receivers in place.
7.2.2 With the plastic bristle brush or rubber stopper, brush the specimen through the No. 20 and No. 50 sieves.
7.2.3 With the soft paint brush, brush the specimen through the No. 100 sieve. On all sieves, be certain that all fibrous material
is brushed through.
7.2.4 Carefully remove all material retained on each sieve and weigh individually (without sieve) on the balance pan.
7.2.4.1 Weigh the material retained on each sieve to the nearest 0.00035 oz (0.01 g).
8. Calculation
8.1 Calculate the percentage of non-fibrous material for one specimen 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 sieve plus No. 100 sieve masses together noting as WP and calculate as follows:
WP ~100!
WC 5
WT
where:
WC = % mass of non-fibrous material for one specimen,
WP = mass of material on all sieves, and
WT = mass of specimen after firing/before seperation.
8.2 Adding the total percentages of all WC(s) (minimum of three specimens/tests) and dividing by the number of WC(s) equals
the average total percent of shot (shot content).
9. Report
9.1 Report the following information:
C1335 − 12 (2017)
9.1.1 A description of the material being tested, including specimen source (company name and manufacturing location), color,
production code, or any other information that will help identify specimen.
9.2 The non-fibrous content method used.
9.3 The percentage by weight retained for each sieve size, as well as the total percent non-fibrous material (shot content) to the
nearest tenth of a percent. The total percentage shot content will be reported for the average of at least three separate specimen
results in accordance with 6.1.
9.4 The temperature at which the material was fired and the time the U.S.A. Standard Sieve Shaker Machine was operated.
10. Precision and Bias
10.1 Precision—The test results for representation of performance of the material will depend on the variability of the material,
plus sampling and specimen preparation.
10.1.1 The results were evaluated using Practice E691. Repeatability and reproducibility are herein defined as 2.8 times the
corresponding standard deviation to obtain a 95% confidence level. Repeatability is the variability between test results within each
laboratory, and reproducibility is the variability between test result
