A nu
2、mber in parentheses indicates the year of last reapproval.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 selection ofmarble for gen
3、eral building and structural purposes. Refer to Guides C1242 and C1528 for the appropriate selection and use ofmarble dimension stone.1.2 Dimension marble shall include stone that is sawed, cut, split, or otherwise finished or shaped into blocks, slabs or tiles, andshall specifically exclude molded,
4、 cast and artificially aggregated units composed of fragments, and also crushed and broken stone.1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used
5、independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.2.

Soundness5.1 Marbles are further classified into four “Soundness” groups: A, B, C, and D. Classifications are based on the propertiesencountered
9、 in fabrication and has no reference whatsoever to comparative merit or value. Marble is classified by its producer.5.2 The Soundness classifications indicate what repairs may be necessary prior to or during installation, based on standard tradepractices.1 This specification is under the jurisdictio

13、editions as appropriate.

United States15.3 The groupings A, B, C, and D, should be t
14、aken into account when specifying marble, for all marbles are not suitable forall building applications. This is particularly true of the comparatively fragile marbles classified under Soundness Groups C andD, which may need additional fabrication before or during installation. Only Soundness GroupA
15、marble should be used for exteriorinstallations, or any applications that require the stone panel to resist lateral loads or to bear weight without reinforcement.5.3.1 The four groups are:Group ASound marbles with uniform and favorable working qualities; containing no geological flaws, voids, spalls
16、, cracks,open seams, pits or other defects.Group B Marble similar in soundness to Group A, but with less favorable working qualities; may have some minor smallholes or voids that may require a limited amount of one or more of the following: waxing3, sticking4, and filling5.Group CMarble with some va
17、riations in working qualities; geological flaws, voids, and lines of separation are common. Itis standard practice to repair these variations by one or more of the following methods: waxing3, sticking4, filling5, cementing, orother forms of additional reinforcement.Group D Marbles similar in soundne
18、ss to Group C, but containing a larger proportion of natural faults, maximum variationsin working qualities, and requiring more of the same methods of finishing.66. Physical Properties6.1 Marble supplied under this specification shall conform to the physical requirements prescribed in Table 1.6.2 Ma
19、rble for exterior dimension use shall be Soundness GroupAstone, free of spalls, cracks, open seams, pits, or other defectsthat are likely to impair its structural integrity in its intended use.6.3 Marble for interior use may be Soundness Group A, B, C or D.6.4 Soundness Group B and C marbles can be
20、reinforced, filled or cemented for use on light- to medium-duty walking surfacesand other interior applications.6.5 Soundness Group D marbles can be reinforced, filled or cemented for use on vertical interior applications. This group mayalso be suitable for use in some light-to medium-duty interior
21、pedestrian surface applications.7. Sampling7.1 Samples for testing to determine the characteristics and physical properties shall be representative of the marble to be used.3 Waxing refers to the practice of filling minor surface imperfections such as voids or sand holes with melted shellac, cabinet
22、makers wax or certain polyester compounds.It does not refer to the application of paste wax to make the surfaces shinier.4 Sticking describes the butt edge repair of a broken piece now generally done with dowels, cements or epoxies. The pieces are “stuck” together, thus “sticking.”5 Fillingvoids, su
23、ch as those which occur naturally in marble, can be filled with polyester compounds.6 A “liner” is usually a thin slab of stone cemented to the back of a piece of finished marble for reinforcing.TABLE 1 Physical RequirementsNOTE 1The values in Table 1 were established using samples prepared accordin

On commercial or institutional stairways, floors, and platforms subject to heavy foot traffic, a minimum abrasion hardness of 12.0 isrecommended. W
27、here two or more marbles are combined for color and design effects, there should be no greater difference than 5 points in abrasion resistance.C The supplier of the No. 60 Alundum abrasive, Norton, has indicated that the formula for Norton treatment 138S has been changed. The new abrasive is currren
28、tly moreaggressive, resulting in lower abrasive hardness values (Ha) than when the standard was initially established. As such, care should be taken when interpreting Ha valuesfrom tests using the new abrasive, particularly with regard to currentASTM stone standard specification requirements for abr
29、asion resistance, which were developed whenthe original abrasive was still in use. Committee C18 is actively studying alternatives to address this issue.C Abrasion Resistance Test Method C1353 will eventually replace Test Method C241/C241M. It is not necessary to perform both tests.Availability of t
