ASTM C1527 C1527M-2010 Standard Specification for Travertine Dimension Stone《石灰华规格石料标准规范》.pdf

1、Designation: C1527/C1527M 10Standard Specification forTravertine Dimension Stone1This standard is issued under the fixed designation C1527/C1527M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, the year of last revision. A number

2、in parentheses indicates the year of lastreapproval. A superscript 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 gen

3、eral building 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 s

4、tated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.2.

Physical Properties4.1 Travertine supplied under this specificatio

8、n shall con-form to the physical requirements prescribed in Table 1.4.2 Travertine shall be free of minerals that may causeobjectionable staining under normal environments of use.4.3 Voids in travertine are a natural characteristic of thematerial and shall be considered in assessing the permissiblen

9、atural variations suitable for a particular application.4.3.1 Some travertines may not be suitable for exterior usein areas subject to frequent freeze-thaw 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

10、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 permissiblenatural variations in material characteristics for material to beproduced for the project, shall be established by controlsamples. Representative sam

11、ples shall be selected prior toproduction by viewing a sufficient number of samples thatshow the complete range of variations in color and texture ofthe travertine specified.5. Sampling5.1 Samples, if required, for testing to determine the char-acteristics and physical properties shall be representa

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, Norto

23、n, 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 th

24、e 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.C1527/C1527M 102
