Terminology3.1 Definitions:3.1.1 For definitions of terms used in 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 areaso

16、f the material. This would include traditional mineral surfacedrolls, “3 Tab” 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 o

17、f NonuniformComposition” designates products that are intentionally manu-factured 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 produ

18、ct has the samethickness). See Fig. 1, Type 3.3.1.4 As referenced in 15.4, “Materials 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 runni

19、ng the longdimension of a roll product (before samples or specimens arecut) or the long dimension of a shingle, unless otherwiseknown and agreed to between supplier and purchaser. “CrossDirection” (indicated as CD) designates the direction perpen-dicular to the MD.3.1.6 A production lot is defined a

20、s all material producedwithin one production shift of the same type, 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).NOTE 1Not to scale.NOTE 2Type 3 has been illustr

21、ated 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 of Asphalt-Coated Roll Roofing and ShinglesD228/D228M 1624. Significance and Use4.1 These test me

22、thods include procedures for sampling,examination, physical testing, and analyses 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, pap

23、ers, and mineral surfacing.4.2 These test methods include tests that are not required byevery product standard that references Test Methods D228/D228M. The individual product standards are the authority forwhich tests are required for compliance. It is not prohibited torun tests in addition to those

24、 required in the product standards,but these test methods make no claim to their suitability orsignificance.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 ma

25、ss within the lot and is determined by the two-stepsampling plan in 7.4.4.4 The results 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

26、 eachof the components.5. Materials5.1 Filter PaperThe extractions for analysis of 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

27、% in an 80C 176F oven and storeduntil needed in a desiccator.NOTE 1Whitman No. 50 filter 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 T

28、ype 1A single thickness of glass felt, coated withasphalt and mineral surfacing such as in Specifications D2178/D2178M, D3462/D3462M, D3909/D3909M, D4601/D4601M,and D4897/D4897M. The backing material (designated “FineMineral Surfacing” in Fig. 1) shall be permitted to be anysuitable material that pr

29、events these products from stickingtogether while packaged.6.1.2 Type 2A single thickness of asphalt-saturated feltcoated with asphalt and mineral surfacing such as in Specifi-cations D225, D2626/D2626M, and D6380/D6380M, Class M.The backing material (designated “Fine Mineral Surfacing” inFig. 1) sh

30、all be permitted to be any suitable material thatprevents these products from sticking together while packaged.6.1.3 Type 3Similar to Type 2, but asphalt coated andsurfaced with mineral granules for part of one side of thesaturated felt such as in Specification D6380/D6380M, ClassWS. This type also

31、includes products similar to Type 1 or Type2 that have overlay or embossed areas. This does not includeproducts that are fabricated in multiple 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

32、of the adhesive or quality of thebond, or both, is outside the scope of this test method. Fig. 1illustrates a typical configuration for Type 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

33、 intended to limit or excludeproducts with similar, but not identical constructions. Ex-amples of known variations, which shall not be prohibitedinclude (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

34、different relative proportions forthe layers, and6.1.4.4 Materials with other core compositions7. Sampling7.1 The rolls or packages selected 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 sel

35、ect any material that shows visual indications of damagefrom shipping or handling. Determine the average net mass ing/m2lb100 ft2 and the 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, foll

Where a productstandard requires it, the loose surfacing is to be collected andthe mass determined.8.3 Packaging and Fixture MassDetermine and record themass to the nearest 0.1 kg 0.2 lb of the packaging and al

Selection of Representative Specimens, All RoofingTypes9.1 Several product standards reference sampling as desig-nated in Test Methods D228/D228M for tests that are notsp

46、ecifically covered by Test Methods D228/D228M. Unlessotherwise specified in these test methods, the large specimensand small test specimens shall all be selected from therepresentative sample (roll or package selected in Section 7)that has the individual net mass per unit area closest to theaverage

47、net mass per unit area for the combined representativesamples as determined in Section 8. If more than one roll orIn Section 7, initial “Representative Samples” are selected (typically five per lot). These are full bundles or rolls. These are the samples used in Section 8.In Section 9, one large “Sp

48、ecimen” 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 representative sample.In Section 10 (where product standards require measurement of w

49、ater 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 cut from each of the “Large Specimens” for analysis by Section 16 (for gla
