ASTM C615 C615M-2011 Standard Specification for Granite Dimension Stone《花岗岩规格料标准规格》.pdf

1、Designation: C615/C615M 11Standard Specification forGranite Dimension Stone1This standard is issued under the fixed designation C615/C615M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in pare

2、ntheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers the material characteristics,physical requ

3、irements, and sampling appropriate to the selec-tion of granite for general building and structural purposes.Refer to Guides C1242 and C1528 for the appropriate selectionand use of granite dimension stone.1.2 Granite dimension stone shall include stone that issawed, cut, split, or otherwise finished

4、 or shaped, and shallspecifically exclude molded, cast, or otherwise artificiallyaggregated units composed of fragments, crushed and brokenstone.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equ

5、ivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.2.

Classification4.1 Granite dimension stone under this specification shall begranite used for:4.1.1 Exterior and interior cladding of buildings and struc-tures;4.1.2 Curbstone, paving, and landscape features;4.1.3 Structural components having established

9、dimensions;4.1.4 Grade separations and retaining walls; and4.1.5 Monuments.5. Physical Properties5.1 Granite supplied under this specification shall conformto the physical requirements prescribed in Table 1. See 5.1.2for possible variations from this table.5.1.1 The minimum compressive strength, fle

10、xural strength,and modulus of rupture shall be based upon the minimumaverage strength of specimens tested in four conditions: wet ordry and parallel or perpendicular to rift.5.1.2 The physical properties given in Table 1 representproperties of granite that have a history of successful use forgeneral

11、 building and structural purposes. Granite with strengthor abrasion resistance less than the minimum values prescribedin Table 1 may be used provided that competent engineeringauthority has evaluated relevant characteristics of the granite.This evaluation shall consider both structural effects andma

12、terial characteristics such as durability, permanent volumechange, modulus of elasticity. 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 toimpair its structural integrity in its intended use.1This spe

16、s for all material tobe produced for the project, shall be established by controlsamples. Select representative samples by viewing a sufficientnumber of physical samples prior to production that show thecomplete range of variations in color and texture of the granitespecified.6. Sampling6.1 Samples,

17、 if required, for testing to determine the char-acteristics and physical properties shall be representative of thegranite to be used.ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentionedin this standard.

The new abrasive is currently moreaggress

25、ive, resulting in lower abrasive hardness values (Ha) than when the standard was initially established. As such, care should be taken when interpreting Havaluesfrom tests using the new abrasive, particulary with regard to current ASTM stone standard specification requirements for abrasion resistance

26、, which were developed whenthe original abrasive was still in use. Committee C18 is actively studying alternatives to address this issue.CAbrasion 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 112
