ASME Y14.37-2019 pdf download.Product Definition for Composite Parts.
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. (b) ReferencetootherASMEY14standardsinthetextwithadatefollowingthestandarddesignatorindicatesthatonly that issue of the standard shall be used to meet the requirement.
NotesdepictedinthisStandardinALLUPPERCASElettersareintendedtoreflectactualdatasetentries.Notesdepicted in initial uppercase orlowercase letters are to be considered supportingdata to the contents ofthis Standard and are not intended for literal entry in data set. A statement requiring the addition of a note with the qualifier “such as” is a requirement to add a note, and the content of the note is allowed to vary to suit the application. 1.7 Acronyms and Abbreviations Acronyms and abbreviations are spelled outthe firsttime used in this Standard, followed bythe acronym orabbrevia- tion in parentheses. The acronym is used thereafter throughout the text. 1.8 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.
ThefiguresinthisStandardareintendedonlyasillustrationstoaidtheuserinunderstandingthepracticesdescribedin the text. In some cases, figures show a level ofdetail as needed for emphasis. In other cases, figures are incomplete by intentsoastoillustrateaconceptorfacetthereof. 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 height Fabric, Nonwoven fabric, nonwoven: textile structure produced by bonding or interlocking offibers, or both, accomplished by mechanical, chemical, thermal, or solvent means, and combinations thereof (CMH-17). 3.18 Fabric, Woven fabric, woven: a generic material construction consisting of interlaced yarn or fibers, usually a planar structure. Spe- cifically, cloth woven in an established weave pattern from advanced fiberyarns and used as the fibrous constituentin an advanced composite ply. 3.19 Fiber Orientation Array fiberorientation array:anarrayofdiscretelocationsonthelaminatereferencesurfaceusedtodefinetheprimary secondary fiber orientation directions.
