Terminology3.1 Definitions:3.1.1 For definitions of terms used i
15、n these test methods, seeTerminology D1079.3.1.2 As referenced in 15.1, “Materials of Uniform Compo-sition” designates products that are manufactured to be thesame thickness, ply count, and mass per unit area in all areasof the material. This would include traditional mineral surfacedrolls, “3 Tab”
16、shingles, and other shingles that have areas ofmaterial removed for appearance purposes (cut-outs) but therest of the shingle is of uniform composition. See Fig. 1, Type1 or Type 2.3.1.3 As referenced in 15.2, “Materials of NonuniformComposition” designates products that are intentionally manu-factu
17、red to have different thickness or mass per unit area withindifferent areas of the product. Examples of materials ofnonuniform composition are selvage edge rolls and overlaid orembossed shingles (where not all of the product has the samethickness). See Fig. 1, Type 3.3.1.4 As referenced in 15.4, “Ma
18、terials of Multiple LayerComposition” designates products that are fabricated in mul-tiple layers. See Fig. 1, Type 4.3.1.5 As referenced in these test methods, “Machine Direc-tion” (indicated as MD) is the direction running the longdimension of a roll product (before samples or specimens arecut) or
19、 the long dimension of a shingle, unless otherwiseNOTE 1Not to scale.NOTE 2Type 3 has been illustrated without asphalt coating or fine mineral surfacing on the reverse side. It is not prohibited to fabricate this productwith asphalt coating or fine material surfacing on the reverse side.FIG. 1 Types

21、composition, andcolor (where applicable). A delivery lot is defined as ashipment or fraction thereof representing a product of the sametype, composition, and color (where applicable).4. Significance and Use4.1 These test methods include procedures for sampling,examination, physical testing, and anal
22、yses of asphalt rollroofing, cap sheets, and shingles used in roofing and water-proofing. Other components of these materials are allowed toinclude, but are not limited to, felts, mats, films, foils, mineralstabilizers, papers, and mineral surfacing.4.2 These test methods include tests that are not
23、required byevery product standard that references Test Methods D228. Theindividual product standards are the authority for which testsare required for compliance. It is not prohibited to run tests inaddition to those required in the product standards, but thesetest methods make no claim to their sui
24、tability or significance.4.3 Five random samples are required from lots equal to orless than 1000 packages. The number of samples required forlots greater than 1000 packages is dependent on the variation inthe unit mass within the lot and is determined by the two-stepsampling plan in 7.4.4.4 The res
25、ults of a visual examination, physical testing, andcompositional analysis are required for each sample. Theanalytical data are further used to compute the probableminimum and the probable range for the average mass of eachof the components.5. Materials5.1 Filter PaperThe extractions for analysis of
26、glass feltproducts (Section 16) and analysis of roofing products withorganic felt (Section 17) require the use of filter paper with aparticle retention of 2.7 m (see Note 1), This filter paper isdried for 60 min 6 10 % in an 80C 176F oven and storeduntil needed in a desiccator.NOTE 1Whitman No. 50 f
27、ilter paper 185 mm has been foundsatisfactory for this use.6. Types of Roofing6.1 Asphalt-coated roll roofing and shingles are divided intothe following types for the purposes of these test methods (seeFig. 1).6.1.1 Type 1A single thickness of glass felt, coated withasphalt and mineral surfacing suc
28、h as in Specifications D2178,D3462, D3909, D4601, and D4897. The backing material(designated “Fine Mineral Surfacing” in Fig. 1) shall bepermitted to be any suitable material that prevents theseproducts from sticking together while packaged.6.1.2 Type 2A single thickness of asphalt-saturated feltcoa
29、ted with asphalt and mineral surfacing such as in Specifi-cations D225, D2626, and D6380, Class M. The backingmaterial (designated “Fine Mineral Surfacing” in Fig. 1) shallbe permitted to be any suitable material that prevents theseproducts from sticking together while packaged.6.1.3 Type 3Similar t
30、o Type 2, but asphalt coated andsurfaced with mineral granules for part of one side of thesaturated felt such as in Specification D6380, Class WS. Thistype also includes products similar to Type 1 or Type 2 thathave overlay or embossed areas. This does not include prod-ucts that are fabricated in mu
31、ltiple layers.6.1.4 Type 4This material is comprised of multiple layersbonded with a suitable adhesive, typically a bituminous mate-rial. Evaluation of the nature of the adhesive or quality of thebond, or both, is outside the scope of this test method. Fig. 1illustrates a typical configuration for T
32、ype 4. This “Type”description is provided to aid the user in understanding how tomatch a given product composition and assembly to itscorresponding Type. It is not intended to limit or excludeproducts with similar, but not identical constructions. Ex-amples of known variations, which shall not be pr
33、ohibitedinclude (but are not limited to):6.1.4.1 Materials using other adhesives,6.1.4.2 Materials fabricated with more than two layers,6.1.4.3 Materials that use different relative proportions forthe layers, and6.1.4.4 Materials with other core compositions7. Sampling7.1 The rolls or packages selec
34、ted in accordance with thissection constitute the representative sample used in Sections 8and 9.7.2 Select five rolls or packages from the lot at random. Donot select any material that shows visual indications of damagefrom shipping or handling. Determine the average net mass perg/m2lb/100 ft2 and t
35、he standard deviation in accordance with8.1-8.8.7.3 If the lot is 1000 or fewer rolls or packages, proceed toSection 8. If the lot is 1001 or greater in number, follow thesecond part of the sampling plan in 7.4.7.4 Calculate the required number of samples based on thestandard deviation (s) of the pr

37、76),andd = 100 g/m22 lb/100 ft2 (the mean mass obtained fromthe analysis should be within 6100 g/m2of the truevalue, with 95 % confidence).7.5 See Fig. 2.8.

Sele
45、ction of Representative Specimens, All RoofingTypes9.1 Several product standards reference sampling as desig-nated in Test Methods D228 for tests that are not specificallycovered by Test Methods D228. Unless otherwise specified inthese test methods, the large specimens and small test speci-mens shal
46、l all be selected from the representative sample (rollor package selected in Section 7) that has the individual netmass per unit area closest to the average net mass per unit areafor the combined representative samples as determined inSection 8. If more than one roll or package needs to be selectedt
47、o provide sufficient specimens for all the tests dictated withinthe product standard, any additional specimens shall be se-lected from the representative sample that has the net mass perIn Section 7, initial “Representative Samples” are selected (typically five per lot). These are full bundles or ro
48、lls. These are the samples used in Section 8.In Section 9, one large “Specimen” is taken from each representative sample (full shingles from 8.5 or a portion of each roll selected in Section 7). These are confirmedto be within 1.5 % of the mass per area (from 8.6) for the corresponding representativ
49、e sample.In Section 10 (where product standards require measurement of water content per Test Method D95), 50-g small test specimens are taken from each “Large Specimen”for determination of water.In Section 11, five MD and five CD small test specimens are cut from one of the “Large Specimens” for evaluation of pliability.In Section 12, two small test specimens are cut from one of the “Large Specimens” for evaluation of behavior on heating.In Section 15, small test specimens (three for glass felt, four for organic felt) are c
