ASTM C1527-2009 Standard Specification for Travertine Dimension Stone《石灰华规格石料的标准规范》.pdf

1、Designation: C 1527 09Standard Specification forTravertine Dimension Stone1This standard is issued under the fixed designation C 1527; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parenthes

2、es indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers the material characteristics,physical requirements, and sampling appropriate to the selec-tion of travertine for general buildin

3、g and structural purposes.1.2 Dimension travertine shall include stone that is sawed,cut, split, or otherwise finished or shaped and shall specificallyexclude molded, cast, or otherwise artificially aggregated unitscomposed of fragments, and also crushed and broken stone.1.3 The values stated in inc

4、h-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.2.

7、in-cut, adjdescribes stone that is cut perpendicu-lar to the natural veining.4. Physical Properties4.1 Travertine supplied under this specification shall con-form to the physical requirements prescribed in Table 1.4.2 Travertine shall be free of minerals that may causeobjectionable staining under no

8、rmal environments of use.4.3 Voids in travertine are a natural characteristic of thematerial and shall be considered in assessing the permissiblenatural variations suitable for a particular application.4.3.1 Some travertines may not be suitable for exterior usein areas subject to frequent freeze-tha

9、w cycles.4.3.2 Travertine that is fleuri-cut (cross-cut) rather thanvein-cut can be expected to experience certain problems,because some areas of the exposed surface will consist of onlya thin layer of stone that covers a void in the stone.4.4 The desired color and texture, with their permissiblenat

10、ural variations in material characteristics for material to beproduced for the project, shall be established by controlsamples. Representative samples shall be selected prior toproduction by viewing a sufficient number of samples thatshow the complete range of variations in color and texture ofthe t

11、ravertine specified.5. Sampling5.1 Samples, if required, for testing to determine the char-acteristics and physical properties shall be representative of thetravertine to be used.1This specification is under the jurisdiction of ASTM Committee C18 onDimension Stone and is the direct responsibility of

Where two or more stone varieties are combined for color and design effects, there should be no greater difference than five points inabrasion resistance.BThe supplier of the No. 60 Alundum abrasive, Nort

22、on, has indicated that the formula for Norton treatment 138S has been changed. The new abrasive is currently moreaggressive, resulting in lower abrasion resistance values (Ha) than when the standard was initially established. As such, care should be taken when interpreting Havaluesfrom tests using t

23、he new abrasive, particularly with regard to currentASTM stone standard specification requirements for abrasion resistance, which were developed whenthe original abrasive was still in use.CIt is not necessary to perform both tests. Availability of the proper equipment and materials by the testing laboratory may determine which test is performed.C1527092
