1、Designation: C119 11Standard Terminology Relating toDimension Stone1This standard is issued under the fixed designation C119; 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 parentheses indica
2、tes the year of last reapproval. Asuperscript 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.INTRODUCTIONDimension stone, as used here, is natural stone that has been selected and fabrica
3、ted to specific sizesor shapes, with or without one or more mechanically dressed or finished surfaces, for use as buildingfacing, curbing, paving stone, monuments and memorials, and various industrial products. The termdimension stone is in contradistinction to crushed and broken stone, such as is u
4、sed for aggregate,roadstone, fill, or chemical raw materials. Because all stone is a natural material, the definitionexcludes all manmade materials that simulate stone. In common practice, some dimension stones arereinforced, filled, or surface treated.Terms used in definitions and nomenclature shal
5、l be interpreted in accordance with commonlyaccepted scientific and technical terms of the geological sciences except as otherwise specificallynoted.Examples of such exceptions are the broader commercial definitions of granite and marble, whichhave become well established in the dimension stone indu

Definitions and termsincluded in these definitions have been formulated in accordance with common industrial usage wherethis is not in conflict with current scientific usage.GENERAL TERMSanchorin general, a metal shape inserted into a slot or holein the stone that provides for the tr

For marbleor granite, cubic stock is a unit that is greater than

In common practice, some dimension stonesare reinforced, filled, or surface treated.

15、Drive, PO Box C700, West Conshohocken, PA 19428-2959, United States.Durability is based on the length of time that a stone canmaintain its innate characteristics in use.

44、 a plethora of finishes. This sectiondescribes common finishes and classifies them into a number offamilies by relief or roughness. The finishes in each family arealso arranged from the least relief to the most relief.Stone finishes are a complex matter for a number of reasons.New manufacturing or f
45、inishing methods or variations orcombinations of other methods of finishing stone are continu-ally being developed. Stone finish names sometimes overlap orare variations of other finishes.Finish options for any kind of stone vary by the geologiccategory of the stone (whether igneous, metamorphic, or
46、sedimentary) and the unique combination of geological orphysical properties of the stone type. This means that anyparticular finish cannot be put on every type of stone (seeApplicability of Finishes for Various Stone Types Table inGuide C1528 for Selection of Dimension Stone for ExteriorUse). The in
47、dividual definitions are sometimes nonspecific ornearly overlap. In practice, a detailed definition of a specificstone finish is established between the producer and designerthrough dialogue, or reference sample(s), or both.The family or individual title “finish” will be used uniformlythroughout thi
48、s section for ease of reference, although the term“surface” would be more accurate when no work has been doneon it and no improvements made postquarry (as in certainFIG. 1 RusticationC119 113rough finishes; see Note 2). “Surface” will be used uniformlyin the sense of the outward appearance or face o
49、f the stone.Thus we have the Least Textured Finishes (family) and thePolished (finish)a highly-reflective surface, and so forth.Surface VariationThe dimensions of variation in surface profile given in thefollowing definitions are for indicative purposes only. Thevalues do not denote acceptable tolerances or minimum ormaximum values of surface variation for any given finish.LEAST TEXTURED FINISHES(less than 1 mm 132 in. of surface variation)polisheda highly-reflective surface, produced by mechanicalabrasion
