ASME Y14.37:2019 pdf download.Product Definition for Composite Parts
1 SCOPE
This Standard establishes the requirements for composite product definition that are not covered within the existing ASME Y14 Series of standards. 1.1 ASME Y14 Series Conventions The conventions in paras. 1.1 through 1.10 are used in this and other ASME Y14 standards. 1.2 Mandatory, Nonmandatory, Guidance, and Optional Words (a) The word “shall” establishes a requirement. (b) The word “will” establishes a declaration of purpose on the part of the design activity. (c) The word “should” establishes a recommended practice. (d) The word “may” establishes an allowed practice. (e) The words “typical,” “example,” “for reference,” or the Latin abbreviation “e.g.” indicate suggestions given for guidance only. (f) The word “or” used in conjunction with a requirement or a recommended practice indicates that there are two or more options for complying with the stated requirement or practice. (g) The phrase “unless otherwise specified” orUOS shall be used to indicate a defaultrequirement. The phrase is used when the defaultis a generallyapplied requirementand an exception maybe provided byanother documentor require- ment. 1.3 Cross-Reference of Standards Cross-reference ofstandards in text with or without a date following the standard designator shall be interpreted as follows: (a) Reference to otherASME Y14 standards in the textwithouta date followingthe standard designatorindicates that the issue of the standard identified in the References section (section 2) shall be used to meet the requirement. 1.4 Invocation of Referenced Standards The following examples define the invocation ofa 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. 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 paragraph(s) within the standard are 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 ofthe 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 forguidance only. Forexample,“For gagingprinciples, see ASME Y14.43” is onlyforguidance and no portion of the standard is invoked.
1.9 Figures
In some cases, figures show a level ofdetail as needed for emphasis. In other cases, figures are incomplete by intentsoastoillustratea conceptorfacet the reof. Theabsenceoffigure(s) hasnobearingontheapplicabilityofthestated 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 ofa listing is not a reason to assume inapplicability. Some figures are illustrations ofmodels in a three-dimen- sional environment. The absence ofdimensioning and tolerancing annotations in a view may indicate that the product definition 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 applicable letter height in accordance with ASME Y14.2. Multiview drawings contained within figures are third-angle projection.
