1.3.2 Cross-Reference of Standards Cross-reference of standards in text with or without a date following the standard designator shall be inter- preted as follows:
(a) Reference to other ASME Y14 standards in the text withoutadatefollowingthestandarddesignatorindicates the edition of the standard identified in the References section (Section 2) shall be used to meetthe requirement.
(b) Reference to other ASME Y14 standards in the text with a date following the standard designator indicates that only that edition of the standard shall be used to meet the requirement.
1.3.3 Invocation of Referenced Standards The following examples define the invocation ofa stan- dardwhenspecifiedinSection2 andreferencedinthetext of this Standard:
(a) When a referenced standard is cited in the textwith no limitations to a specific subject or paragraphs of the standard, the entire standard is invoked. For example, “Dimensioning and tolerancing shall be in accordance with ASME Y14.5” is invoking the complete standard because the subject of the standard is dimensioning and tolerancing and no specific subject or paragraphs within the standard are invoked.
(b) When a referenced standardis cited in the textwith limitations to a specific subject or paragraphs ofthe stan- dard, onlythe paragraphs on thatsubjectare invoked. For example, “Assign part or identifying numbers in accordance with ASME Y14.100” is invoking only the para- graphs on part or identifying numbers because the subject of the standard is engineering drawing practices andpartoridentifyingnumbersisaspecificsubjectwithin the standard.
(c) When a referenced standard is cited in the text without an invoking statement such as “in accordance with,” the standard is invoked for guidance only. For example, “For gaging principles, see ASME Y14.43” is only for guidance and no portion of the standard is invoked.
1.3.4 Definitions Section 3 provides definitions specific to this Standard. For definitions of words used in but not defined in this Standard, see Merriam-Webster’s Unabridged Dictionary at https://www.merriam-webster.com/.
1.3.5 Parentheses Following a Definition When a definition is followed by a standard referenced in parentheses, the standard referenced in parentheses is the source for the definition.
1.3.6 Notes Notes depicted in this Standard in ALL UPPERCASE letters are intended to reflect actual product definition entries. Notes depicted in initial uppercase or lowercase letters are to be considered supporting data to the contents of this Standard and are not intended for literal entry on the product definition. A statement requiring the addition of a note with the qualifier “such as” is a requirement to add a note, and the content ofthe note is allowed to vary to suit the application.
1.3.7 Acronyms and Abbreviations Acronyms and abbreviations are spelled out the first time used in this Standard, followed by the acronym or abbreviation in parentheses. The acronym is used there- after throughout the text.
1.3.8 Units The International System ofUnits (SI) is featured in this Standard. It should be understood that U.S. Customary units could equally have been used without prejudice to the principles established.
1.3.9 Figures The figures in this Standard are intended only as illus- trations to aid the user in understanding the practices described in the text. In some cases, figures show a level of detail as needed for emphasis. In other cases, figures are incomplete by intent so as to illustrate a concept or facet thereof. The absence of figures has no bearing on the applicability of the stated requirements orpractice. To complywith the requirements ofthis Stan- dard, actual data sets shall meetthe contentrequirements setforthinthetext.ToassisttheuserofthisStandard,alist of paragraphs that refer to an illustration appears in the lowerright-handcornerofeachfigure. Thislistmaynotbe all inclusive. The absence ofa paragraph reference is nota reason to assume inapplicability. Some figures are illus- trations of models in a three-dimensional (3D) environ- ment. The absence of dimensioning and tolerancing annotations in a view may indicate that the product defi- nition is defined in three dimensions. Dimensions that locate or orient and are not shown are considered basic and shall be queried to determine the intended requirement. When the letter “h” is used in figures for letter heights or for symbol proportions, select the appli- cable letter height in accordance with ASME Y14.2. Multi- view drawings contained within figures are third-angle projection.
