14、A 19428-2959. United States15. Physical Properties5.1 Granite supplied under this specification shall conform to the physical requirements prescribed in Table 1. See5.1.2FootnoteB for possible variations from this table.5.1.1 The minimum compressive strength, flexural strength, and modulus of ruptur
15、e shall be based upon the minimum averagestrength of specimens tested in four conditions: wet or dry and parallel or perpendicular to rift.5.1.2 The physical properties given in Table 1 represent properties of granite that have a history of successful use for generalbuilding and structural purposes.
16、 Granite with strength or abrasion resistance less than the minimum values prescribed in Table1 may be used provided that competent engineering authority has evaluated relevant characteristics of the granite. This evaluationshall consider both structural effects and material characteristics such as
17、durability, permanent volume change, modulus ofelasticity. thermal expansion, and the like.5.2 Granite shall be sound, durable, and free of spalls, cracks, open seams, pits, or other defects that are likely to impair itsstructural integrity in its intended use.5.3 Granite shall be free of minerals t
18、hat may cause objectionable staining under normal environments of use.5.4 The desired color and texture, with their permissible natural variations in material characteristics for all material to beproduced for the project, shall be established by control samples. Select representative samples by vie
19、wing a sufficient number ofphysical samples prior to production that show the complete range of variations in color and texture of the granite specified.6. Sampling6.1 Samples, if required, for testing to determine the characteristics and physical properties shall be representative of the graniteto

Refer to GuideC1528 Section 62 for potential further evaluation of materials that do not meet the values of this specification, but may

30、ne subject to foot traffic.EThe The supplier of the No. 60 Alundum abrasive, Norton, has indicated that the formula for Norton treatment 138S has beeen changed. The new abrasive is currentlymore aggressive, resulting in lower abrasive hardness values (Ha) than when the standard was initially establi
31、shed. As such, care should be taken when interpreting Havalues from tests using the new abrasive, particulary with regard to currentASTM stone standard specification requirements for abrasion resistance, which were developedwhen the original abrasive was still in use. Committee C18 is actively study
32、ing alternatives to address this issue.FAbrasion Abrasion Resistance Test Method C1353 will eventually replace Test Method C241/C241M and it is not necessary to perform both tests.Availability of the properequipment and materials by the testing laboratory may determine which test is performed.C615/C615M 182
