Terminology3.1 Definitions:3.1.1 For definitions of term

14、s used in these test methods, seeTerminology D 1079.3.1.2 As referenced in 14.1, “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,

15、 “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 14.2, “Materials of NonuniformComposition” designates products that are intentionally m

16、anu-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 product has the samethickness). See Fig. 1, Type 3.3.1.4 As referenced in

17、14.4, “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 running the longdimension of a roll product (before samples or specimens a

18、recut) 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 as all material producedwithin one production shift of the same type,

19、composition, andcolor (where applicable). A delivery lot is defined as aNOTE 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 rev

20、erse side.FIG. 1 Types of Asphalt-Coated Roll Roofing and ShinglesD228062shipment 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 ana

21、lyses 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

22、 required byevery product standard that references Test Methods D 228.The individual product standards are the authority for whichtests are required for compliance. It is not prohibited to runtests in addition to those required in the product standards, butthese test methods make no claim to their s

23、uitability 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 mass within the lot and is determined by the two-stepsampling plan in 6.4.4.4 The re

24、sults 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. Types of Roofing5.1 Asphalt-coated roll roofing and shin

25、gles are divided intothe following types for the purposes of these test methods (seeFig. 1).5.1.1 Type 1A single thickness of glass felt, coated withasphalt and mineral surfacing such as in Specifications D 2178,D 3462, D 3909, D 4601, and D 4897. The backing material(designated “Fine Mineral Surfac

26、ing” in Fig. 1) shall bepermitted to be any suitable material that prevents theseproducts from sticking together while packaged.5.1.2 Type 2A single thickness of asphalt-saturated feltcoated with asphalt and mineral surfacing such as in Specifi-cations D 225, D 2626, and D 6380, Class M. The backing

27、material (designated “Fine Mineral Surfacing” in Fig. 1) shallbe permitted to be any suitable material that prevents theseproducts from sticking together while packaged.5.1.3 Type 3Similar to Type 2, but asphalt coated andsurfaced with mineral granules for part of one side of thesaturated felt such

28、as in Specification D 6380, 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 multiple layers.5.1.4 Type 4This material is comprised of multiple layersbonded with a suitable adhesive, typic

29、ally 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 Type 4. This “Type”description is provided to aid the user in understanding how tomatch a given product compos

30、ition 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 prohibitedinclude (but are not limited to):5.1.4.1 Materials using other adhesives,5.1.4.2 Materials fabricated

31、 with more than two layers,5.1.4.3 Materials that use different relative proportions forthe layers, and5.1.4.4 Materials with other core compositions6. Sampling6.1 The rolls or packages selected in accordance with thissection constitute the representative sample used in Sections 7and 8.6.2 Select fi

32、ve 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/m2(lb/100 ft2) and the standard deviation in accordance with7.1-7.8.6.3 If the lot is 1000 or fewer rolls or packages, proceed

33、toSection 7. If the lot is 1001 or greater in number, follow thesecond part of the sampling plan in 6.4.6.4 Calculate the required number of samples based on thestandard deviation (s) of the preliminary sampling by:n 5t2s2d2(1)where:n = total number of samples required (n 5 more rolls orpackages mus

34、t be selected at random as samples),t = test statistic for number of samples in the preliminarytest series for 4 and a 95 % confidence that thecalculated average mass will not exceed d (t = 2.776),andd = 100 g/m2(2 lb/100 ft2) (the mean mass obtained fromthe analysis should be within 6100 g/m2of the

35、 truevalue, with 95 % confidence).6.5 See Fig. 2.7. As Received Mass and Area Determinations, All Typesof Roofing7.1 Gross MassDetermine and record the mass of eachrepresentative sample to the nearest 0.1 kg (0.2 lb).7.2 Net MassDisassemble each package or unroll eachroll of the representative sampl

36、e; shake off any loose surfacingand determine and record the net mass of all the shingles or theentire roll to the nearest 0.1 kg (0.2 lb). Where a productstandard requires it, the loose surfacing is to be collected andthe mass determined.7.3 Packaging and Fixture MassDetermine and recordthe mass to

37、 the nearest 0.1 kg (0.2 lb) of the packaging and allassociated fixtures shipped with each roll or package of therepresentative sample, such as nails and adhesive.7.4 Dimensions of Roll ProductsMeasure and record thelength and width of each roll of roofing and the selvage widthto the nearest 3 mm (1

38、8 in.).7.5 Shingle Count and DimensionsFrom each of therepresentative sample packages generated in Section 6, countand record the number of shingles in each package. Select oneshingle randomly from each package. Measure the width,length, and cutout dimensions for each of these selectedD228063shingle

39、s to the nearest 1 mm (132 in.). Calculate and record theaverage for each of these measurements.7.6 Calculate the area of the roofing and the net mass perunit area of the roofing. Report the net mass per unit area asg/m2(lb/100 ft2) for each representative sample (withoutpackaging, cut outs or loose

40、 surfacing).7.7 Calculate and record the average net mass per unit areafor the combined representative samples (without packaging,cut outs, or loose surfacing) as (lb/100 ft2).7.8 Calculate and record the estimate of the standard devia-tion by:s 5(X2n 2 12(X!2nn 2 1!(2)where:s = an unbiased estimate

41、 of the standard deviation,(X2= the sum of the squares of the individual massdeterminations,(X)2= the square of the sum of the individual massdeterminations, andn = the number of rolls or packages in the representa-tive sample.7.9 Calculate the 95 % confidence interval for the averagemass by:(Xn6ts=

42、n(3)where:(X = sum of the individual mass determinations, andt = appropriate t statistic for 95 % confidence and n 1dF (t = 2.776 for n = 5; consult standard referencetable for other values of n).8. Selection of Representative Specimens, All RoofingTypes8.1 Several product standards reference sampli

43、ng as desig-nated in Test Methods D 228 for tests that are not specificallycovered by Test Methods D 228. Unless otherwise specified inthese test methods, the large specimens and small test speci-mens shall all be selected from the representative sample (rollor package selected in Section 6) that ha

44、s the individual netmass per unit area closest to the average net mass per unit areafor the combined representative samples as determined inSection 7. If more than one roll or package needs to be selectedto provide sufficient specimens for all the tests dictated withinthe product standard, any addit

45、ional specimens shall be se-lected from the representative sample that has the net mass perunit area that is next closest to the average net mass per unitarea of the combined representative samples.NOTE 1It is the intent of these test methods that whenever notspecifically directed to select specimen

46、s in some other manner, specimensshall be selected from the representative sample that is the closest in massper unit area to the average mass per unit area of the combinedrepresentative samples.8.2 For roll products, select a specimen of roofing, the fullsheet width and at least1m(3ft)inlength from

47、 each roll,starting a minimum of three wraps into the roll. For shingleproducts, the shingles from 7.5 shall be used.In Section 6, initial “Representative Samples” are selected (typically five per lot). These are full bundles or rolls. These are the samples used in Section 7.In Section 8, one large

48、“Specimen” is taken from each representative sample (full shingles from 7.5 or a portion of each roll selected in Section 6). These are confirmedto be within 1.5 % of the mass per area (from 7.6) for the corresponding representative sample.In Section 9 (where product standards require measurement of

49、 water content per Test Method D95), 50-g small test specimens are taken from each “Large Specimen”for determination of water.In Section 10, five MD and five CD small test specimens are cut from one of the “Large Specimens” for evaluation of pliability.In Section 11, two small test specimens are cut from one of the “Large Specimens” for evaluation of behavior on heating.In Section 14, small test specimens (three for glass felt, four for organic felt) are cut from each of the “Large Specimens” for analysis by Section 15 (for glass felt) orby Section 16 (for organ
