A number in parentheses indica

Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.INTRODUCTIONDimension stone, as used here, is natural stone that has been selected and fa

The termdimension stone is in contradistinction to crushed and broken stone, such as

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

This section de-scribes common finishes and classifies them into a numberof families by relief or roughness. The finishes in each fa
45、m-ily are also arranged from the least relief to the most relief.Stone finishes are a complex matter for a number of rea-sons. New manufacturing or finishing methods or variationsor combinations of other methods of finishing stone are con-tinually being developed. Stone finish names sometimesoverlap
46、 or are variations of other finishes.Finish options for any kind of stone vary by the geologiccategory 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 ev
47、ery type of stone (seeApplicability of Finishes for Various Stone Types Table inGuide C1528 for Selection 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 th
48、e producer and designerthrough dialogue, or reference sample(s), or both.The family or individual title “finish” will be used uni-formly throughout this section for ease of reference, al-though the term “surface” would be more accurate when nowork has been done on it and no improvements madepostquar

Thus we have the LeastTextured Finishes (family) and the Polished (finish)ahighly-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 TEXTU
