ASTM C1527-2003 Standard Specification for Travertine Dimension Stone《石灰华规格石料的标准规范》.pdf

1、Designation: C 1527 03Standard 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 (e) 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 buildi

3、ng 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.2.

Physical Properties4.1 Travertine supplied under this specification shall con-form to the physical requirements prescribed in Table 1.4.2 T

7、ravertine 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 permissiblenatural variations suitable for a particular application.4.3.1 Some traver

8、tines 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 the exposed surface will consist of onlya thin layer of stone that covers

9、 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 samples shall be selected prior toproduction by viewing a sufficient number

10、of samples thatshow the complete range of variations in color and texture ofthe travertine specified.1This specification is under the jurisdiction of ASTM Committee C18 onDimension Stone and is the direct responsibility of Subcommittee C18.03 onMaterial Specifications.Current edition approved Dec. 1

Where two or more stone varieties are combined

15、for color and design effects, there should be no greater difference than five pointsin abrasion resistance.BThe supplier of the No. 60 Alundum abrasive, Norton, has indicated that theformula for Norton treatment 138S has been changed. The new abrasive iscurrently more aggressive, resulting in lower

16、abrasion resistance values (Ha) thanwhen the standard was initially established. As such, care should be taken wheninterpreting Havalues from tests using the new abrasive, particularly with regard tocurrent ASTM stone standard specification requirements for abrasion resistance,which were developed w

17、hen the original abrasive was still in use.CIt is not necessary to perform both tests. Availability of the proper equipmentand materials by the testing laboratory may determine which test is performed.1Copyright ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959
