United States13. Terminology3.1 Definitions:3.1.1

15、 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 areasof the material. This would include traditional

16、 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 of NonuniformComposition” designates products t

17、hat 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 product has the samethickness). See Fig. 1, Type 3.

18、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 running the longdimension of a roll product (before

19、 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 as all material producedwithin one production s

20、hift of the same type, 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 materi

21、al surfacing on the reverse side.FIG. 1 Types of Asphalt-Coated Roll Roofing and ShinglesD228/D228M 09 (2014)2shipment 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,e

22、xamination, 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, papers, and mineral surfacing.4.2 These te

23、st 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 required in the product standards,but

24、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 mass within the lot and is determined by

25、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 eachof the components.5. Materials5.1

26、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 % in an 80C 176F oven and storeduntil n

27、eeded 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 Type 1A single thickness of glass felt,

28、coated withasphalt and mineral surfacing such 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 s

29、ingle thickness of asphalt-saturated feltcoated 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 t

30、ogether 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, Class WS. Thistype also includes products similar to Type 1 or Type 2 thathave overlay or embossed areas. This does not

31、 include prod-ucts 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 of the adhesive or quality of thebond, or both, is outside the scope of this test method. Fig

32、. 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 intended to limit or excludeproducts with similar, but not identical constructions. Ex-ample

33、s 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 different relative proportions forthe layers, and6.1.4.4 Materials with other core compositio

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 select any material that shows visual indications of damagefrom shipping or handling. Determine

35、the average net mass ing/m2lb/100 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, follow thesecond part of the sampling plan in 7.4.7.4 Calculate the required number of samples b

41、shingles in each package. Select oneshingle randomly from each package. Measure the width,length, and cutout dimensions for each of these selectedshingles to the nearest 1 mm 132 in. Calculate and record theaverage for each of these measurements.8.6 Calculate the area of the roofing and the net mass

Report the net mass per unit area ing/m2lb/100 ft2 for each representative sample (withoutpackaging, cut outs or loose surfacing).8.7 Calculate and record the average net mass per unit areafor the combined representative samples (without packaging,cut outs, or loose sur

Selection of Representative Specimens, All RoofingTypes9.1 Several product standards reference sampling as desig-nated in Test Methods D228/D228M for tests that are notspecifically covered by Test Methods D228/D228M. Unlessotherwise specified in these te

46、st 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 net mass per unit area for the combined representativesamples as determined in Secti

47、on 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 “Specimen” is taken from each representative sample (full shingles from 8.5 or a portio

48、n 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 water content per Test Method D95), 50-g small test specimens are taken from each “La

49、rge 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 glass felt) orby Section 17 (for organic felt).FIG. 2 Sample Selection Summary and Flow
