2、tes the yearof original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of t

3、he Department of Defense.1NOTEUnits information was editorially corrected in June 2012.1. Scope1.1 These test methods cover the sampling and examination of felts or woven fabrics, saturated or impregnated but not coatedwith asphaltic or coal-tar materials, for use in waterproofing or for the constru

4、ction of built-up roof coverings.1.2The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in eachsystem may not be

5、exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility

6、of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2.

Sampling3.1 From each shipment of the specified saturated felt or fabric, select at random a number of rolls equal to one half the cuberoot of the total number of rolls in the lot. If the specification requires sampling during manufacture, consider the lot to be

10、 theplanned production quantity and select the rolls at uniformly spaced time intervals throughout the production period. The minimumsample shall consist of five rolls. If the calculated number is fractional, express it as the next highest whole number. Forconvenience, the following table, showing t

17、 Identify each individual roll.EXAMINATION OF REPRESENTATIVE SAMPLE4. Gross Mass per Roll4.1 Weigh each roll, intact, to the nearest 100 g (14 lb),lb, and record each weight as the gross mass of that roll.5. Mass of Wrapping Material and Mandrel (Core)5.1 Strip each roll of its wrappings and weigh i

18、t to the nearest 100 g (14 lb).lb. If mandrels (cores) are used, collect them afterthe rolls are unwound and weigh them together, to the nearest 100 g (14 lb).lb. Calculate the average mass of the wrappings andmandrels per roll and record.6. Mandrels (Cores)6.1 Determine the shape of the cross secti

19、on of the mandrels (cores) and report. If circular, measure the outside diameter to thenearest 1 mm (132 in.).in. If square, measure each outside edge to the nearest 1 mm (132 in.).in. Measure and report the lengthof the mandrel projecting beyond each end of each roll to the nearest 5 mm (316 in.).

20、in.7. Net Mass7.1 Subtract the average mass of the wrappings and mandrels (Section 5) from the gross mass of each roll (Section 4) and recordas the net mass of each roll. Calculate the average net mass per roll of the representative sample and record as the average for thelot.8. Appearance and Dimen

21、sions of Rolls8.1 Unwind the rolls. Observe the workmanship and finish, and record pertinent defects. Measure and record the length of eachroll to the nearest 25 mm (1 in.)1 in. and its width to the nearest 1 mm (116 in.).in. Calculate and record the area of materialcontained in each roll to the nea

22、rest 0.1 m2(1 ft1 ft2).8.2 Measure and record the width of the selvage of each roll to the nearest 1 mm (116 in.). in.9. Net Mass per Unit Area9.1 From the net mass (Section 7) and the dimensions (Section 8), calculate the net mass per unit area for each roll, as follows:For Felts:g/m25 A/BC lb/100

24、nit area for the rolls in the representative sample and record it as the average for the lot.10. Selecting a Representative Specimen10.1 Examine in detail the roll having the unit net mass closest to the average unit net mass of the lot. Discard the outsideconvolution and cut a specimen the full wid

25、th of the roll. Make the cuts perpendicular to the sides of the roll, straight and 750 mmD146/D146M 04 (2012)12(30 in.)30 in. apart, to the nearest 1 mm (132 in.).in. Collect loose material, such as sand, if any, that may become detachedfrom the specimen. Measure the width of the specimen to the nea

26、rest 2 mm (116 in.).in. Weigh it, together with any detachedsurfacing, to the nearest 1 g. Calculate the net mass per unit area as follows:For Felts:g/m25 1333.3 D/E lb/100 ft25 1.0582 D/E(3)g/m25 1333.3 D/E lb/100 ft25 1.0582 D/E(3)D0146_D0146M-04R12E01_3For Fabrics:g/m25 1333.3 D/E oz/yd2(4)g/m25

27、1333.3 D/E oz/yd2(4)5 1.5238 D/E D0146_D0146M-04R12E01_4where:D = mass of the specimen, g, andE = width of the specimen, mm (in.).in.The mass so determined shall be within 1 % of the average net mass per unit area (Section 9). If the specimen so selected failsto conform to this requirement, cut addi

28、tional specimens from the same roll until one of the proper mass is obtained. Use thisspecimen for further examination as described in Sections 11-16.11. Detached Comminuted Surfacing11.1 If the material is surfaced with sand or other finely comminuted material, sweep the detached surfacing from the

29、representative specimen with an Osborn brush (or equivalent), brushing in one direction only. Combine the comminuted materialthus removed with the loose material, collected as described in Section 10, and weigh both together to the nearest 1 g. Calculatethis mass in g/m2(lb/100 ftlb/100 ft2), record

30、, and report as detached comminuted surfacing.NOTE 1The Osborn No. 322 Master Duster is the brush prescribed in Section 11. It is filled with Tampico fiber bristles projecting 73 mm (2.9 in.)2.9in. from its holder.312. Moisture12.1 From the representative specimen, cut four 50- by 460-mm (2-2- by 18

31、-in.)18-in. test specimens, as shown in A-1 andA-2 of Fig. 1. Cut them into 25-mm (1-in.)1-in. squares and select about 50 g, at random. Weigh to the nearest 0.1 g and distillwith 100 mL of solvent as prescribed in Test Method D95. Read the volume of water collected in the trap and calculate to gram

32、son the basis that 1 mL weighs 1 g. Calculate the moisture to the nearest 0.5 % of the mass of the specimen used (including thedetached comminuted surfacing, if any) and report as moisture, percentage of net mass.NOTE 2Any sample taken for determination of moisture shall be protected from the time o

Strength13.1 Felts:13.1.1 From the representative specimen, cut ten rectangular test strips, 25 by 150 mm (11 by 6 in.)in. with the fiber grain,as shown at B-1 to B-10 in Fig. 1, and ten strips acros

34、s the grain, as shown at C-1 to C-10 in Fig. 1. Discard any specimens ofperforated felt in which a perforation is within 1 mm (132 in.)in. of an edge. Condition both sets in air at 23 6 2C (73.473.46 3.6F)3.6F for at least 2 h, and test in a room maintained at the same temperature. In case of disput

35、e, specimens shall alsobe conditioned in a controlled relative humidity of 50 6 5 %. Determine the strength in accordance with Test Method D828, exceptas modified herein. At the start of the test, set apart the edges of the jaws of the clamps at 75 6 3 mm (3.03.0 6 0.1 in.).in. Usea pendulum-type te

36、nsile tester with a driven clamp speed of 305 mm (12 in.)/min,12 in./min, or a load-cell-type tensile tester witha rate of jaw separation of 51 mm (2 in.)/min,2 in./min, and a response time of 1.25 s (or faster). Cut additional strips fromadjacent areas of the representative specimen when needed bec

37、ause of discarded specimens or false breaks. False breaks occurwithin 1 in. of the clamping surfaces of the tensile tester jaws. Average the ten readings for each set and multiply by 0.04 to yieldthe strength in kN/m. Report to the nearest 0.1 kN/m for both with and across the fiber grain, respectiv
