Asuperscript epsilon (e) 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 fabr

In common practice, some dimension stones arereinforced, filled, or surface treated.Terms used in definitions and nomenclature s

43、on has a finish or surface;dimension stone has 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
44、for a number of reasons.New manufacturing or finishing 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
45、of the stone (whether igneous, metamorphic, orsedimentary) 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 C 1528 for Select
46、ion of Dimension Stone for ExteriorUse). The individual 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 titl
47、e “finish” will be used uniformlythroughout this 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 certainrough finishes; see Note 2). “Surface” will be used uniformlyin the sense of the outward
48、 appearance or face of 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 de
