3.1?Definitions in this standard are to be regarded as the correct ones for terms found in other ASTM standards of Committee D18. Certain terms may be found in more than one standard issued under the jurisdiction of this committee and many of these terms have been placed in this standard. 3.2?Terms that are defined in some textbooks may differ slightly from those in this terminology standard. Definitions in this terminology standard are to be regarded as correct for ASTM usage. 3.3?See Appendix X1 for References. 3.4?Definitions marked with (ISRM) are included for the convenience of the user and were taken directly from the International Society for Rock Mechanics (see X1.3). 3.5?A number of the definitions include symbols. The symbols appear in italics immediately after the name of the term. 3.5.1?No significance should be placed on the order in which the symbols are presented where two or more are given for an individual term. 3.5.2?The symbols presented are examples; therefore, other symbols are acceptable. 3.5.3?See Appendix X2 for ISRM Symbols. 3.6?A
number of definitions indicate the units of measurements in
brackets and which follow the symbol(s) if given. The applicable
units are indicated by italic capital letters, as follows: 3.6.2?Expressing the units either in SI or the
inch-pound system has been purposely omitted in order to leave the
choice of the system and specific unit to the engineer and the
particular application, for example: 3.7?Where synonymous terms are cross-referenced, the definition is usually included with the earlier term alphabetically. Where this is not the case, the later term is the more significant. 3.8?Grouping of Definitions and Listing of Related TermsTo aide users in finding terms, this terminology standard provides grouping of definitions and listing of related terms. 3.8.1?GroupingsThese groupings are presented in Table 1A.
3.8.1.1?Sub-Term GroupingsThese groupings are presented in Table 1B.
3.8.2?Listings (see Appendix X3)The listing of related terms is given in Table 1C. This listing may include all of the terms defined within standards under the jurisdiction of a specific technical subcommittee, such as D18.14, D18.24, D18.25, and D18.26.
