1.3.2 Cross-Reference of Standards. Cross-reference of standards in text with or without a date following the standard identity is interpreted as follows:
(a) Reference to other ASME Y14 series standards in the text without a date following the standard identity indicates the issue of the standard as identified in the References section (section 2) shall be used to meet the requirement.
(b) Reference to other ASME Y14 series standards in the text with a date following the standard identity indicates that only that issue of the standard shall be used to meet the requirement.
1.3.3 Invocation of Referenced Standards.
The following examples define the invocation of a standard when specified in the References section (section 2) and referenced in the text of this Standard:
(a) When a referenced standard is cited in the text with no limitations to a specific subject or paragraph(s) of the standard, the entire standard is invoked, e.g., “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 paragraph(s) within the standard are invoked.
(b) When a referenced standard is cited in the text with limitations to a specific subject or paragraph(s) of the standard, only the paragraph(s) on that subject is invoked. For example, “assign part or identifying numbers in accordance with ASME Y14.100” is invoking only the paragraph(s) on part or identifying numbers because the subject of the standard is engineering drawing practices, and part or identifying numbers is a specific subject within 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.
1.3.8 Figures. The figures in this Standard are intended only as illustrations 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 figure(s) has no bearing on the applicability of the stated requirements or practice. To comply with the requirements of this Standard, actual data sets shall meet the content requirements set forth in the text. To assist the user of this Standard, a listing of the paragraph(s) that refer to an illustration appears in the lower right-hand corner of each figure. This listing may not be all-inclusive. The absence of a listing is not a reason to assume inapplicability. Some figures are illustrations ofmodels in a three-dimensional environment. The absence ofdimensioningand tolerancingannotations in a view may indicate that the product definition is defined in 3D. 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 height or for symbol proportions, select the applicable letter height in accordance with ASME Y14.2. Multiview drawings contained within figures are third-angle projections.
