2、ast revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers asphalt-sat
3、urated organic felts,with or without perforations, intended to be used with asphaltsconforming to the requirements of Specification D 312 in theconstruction of built-up roofs, and with asphalts conforming tothe requirements of Specification D 449 in the construction ofwater proofing systems.1.2 The
4、values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.3 The following safety hazards caveat pertains only to thetest method portion, Section 8, of this specification: Thisstandard does not purport to address all of the safety concerns,
5、if any, associated with its use. It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.

8、 two types:4.1.1 Type ICommonly called No. 15 asphalt felt.4.1.2 Type IICommonly called No. 30 asphalt felt.5. Materials and Manufacture5.1 In the process of manufacture a single thickness of dryfelt shall be saturated with an asphaltic saturant.5.2 The felt shall be produced principally from organi
9、cfibers. The surface of the felt shall be uniform and relativelysmooth. Upon splitting or tearing on the bias, the felt shallappear reasonably free of lumps or particles of foreign sub-stances.6. Physical Requirements6.1 The material shall conform to the physical requirementsprescribed in Table 1 an
10、d the dimensions and masses pre-scribed in Table 2.6.2 The finished product shall not crack nor be so sticky asto cause tearing or other damage upon being unrolled attemperatures between 10 and 60C (50 and 140F).6.3 Perforated felts shall conform to the same requirementsas the plain type but shall a
11、lso have uniformly spaced perfo-rations.7. Workmanship, Finish, and Appearance7.1 The felt shall be thoroughly and uniformly saturated,and shall show no unsaturated spots at any point upon cutting50-mm (2-in.) wide strips at random across the entire sheet andsplitting them open for their full length

Sampling and Test Methods8.1 Sample the material and determine the properties enu-merated in this specification in
16、accordance with Test MethodsD 146.8.2 Determine the openness of the perforations in saturatedfelts by the following method:8.2.1 Cut three adjacent 305-mm (12-in.) 6 0.5 % squarespecimens across the width of the felt. Determine the numberof perforations per specimen by multiplying the number ofperfo
17、rations per row by the number of rows. Correct fordifferences when rows are off-set from each other. Calculatethe average number of perforations per specimen, P.8.2.2 Place the specimen on a sheet of white paper with thesmoother side up (side from which the needling or perforatingdevice enters the f
18、elt). Use a 50-mm (2-in.) wide natural ornylon bristle paint brush to apply uniformly 15 to 20 cm3(1 to114 in.3) of SAE No. 10 or 10W grade motor oil to eachspecimen. Apply the oil with smooth strokes and withoutundue pressure on the brush. Complete the initial application in1 min and continue to br
19、ush out the oil on the surface for anadditional minute.8.2.3 Lift the perforated felt from the paper upon comple-tion of brushing and count the oil spots showing on the whitepaper beneath as open perforations. Calculate the percent ofopen holes, H, on the basis of the total number of holesdetermined
20、 in 8.2.1.Average the results of three determinationsand report.8.2.4 Measure the size of the perforations using an opticalcomparitor. If round, record diameter of the holes. If square orrectangular, record appropriate dimensions. Calculate the av-erage area, A, of the perforations.8.2.5 Determine t
21、he average venting area as follows:V 5P 3 A 3 HS(1)where:V = vented area, %P = average number of perforations per specimen,A = average area at one hole, mm2(in.2),H = average open holes, %, andS = average specimen area, mm2(in.2).8.2.6 No statement is made about either the precision or thebias of th
22、is method of determining the openness of theperforations in saturated felts since the result merely stateswhether there is conformance to the criteria for successspecified in the procedure.8.3 Determine the saturation percent and saturation effi-ciency by the following method:8.3.1 Calculate the per
23、cent saturation by dividing the massof the saturant by the mass of the desaturated (dry) felt, andmultiply the result by 100.8.3.2 Determine the kerosine number of the desaturated(dry) felt in accordance with Test Method D 727.8.3.3 Calculate the saturation efficiency by dividing thepercent saturati
24、on of the product by the kerosine number timesthe specific gravity of the saturant, and multiply the result by100. A suitable method for determining the specific gravity ofbitumen is Test Method D70.8.3.4 The precision and bias of this method for measuringkerosine value are as specified in Test Meth
