17、s Using a Vibrating Hammer3. Significance and Use3.1 Definitions in this standard are to be regarded as thecorrect ones for terms found in other ASTM standards ofCommittee D18. Certain terms may be found in more than onestandard issued under the jurisdiction of this committee andmany of these terms

18、have been placed in this standard.3.2 Terms that are defined in some textbooks may differslightly from those in this terminology standard. Definitions inthis terminology standard are to be regarded as correct forASTM usage.3.3 See Appendix X1 for References.3.4 A number of the definitions include sy

19、mbols. Thesymbols appear in italics immediately after the name of theterm.3.4.1 No significance should be placed on the order in whichthe symbols are presented where two or more are given for anindividual term.3.4.2 The symbols presented are examples; therefore, othersymbols are acceptable.3.4.3 See

20、 Appendix X2 for Symbols.3.5 A number of definitions indicate the units of measure-ments in parentheses and which follow the symbol(s) if given.The applicable units are indicated by bold capital letters, asfollows:DDimensionlessFForce, such as pound-force, ton-force, newtonLLength, such as inch, foo

Negative exponents designate multiples in the denomina-tor. Degrees of angle are indicated as “degrees.”3.5.2 Expressing the units either in SI or the in

23、ersecond, etc.3.6 Where synonymous terms are cross-referenced, thedefinition is usually included with the earlier term alphabeti-cally. Where this is not the case, the later term is the moresignificant.3.7 Definitions marked with (ISRM) are included for theconvenience of the user and were taken dire
