This Standard defines the types of engineering draw- ings most frequently used to establish engineering requirements. It describes typical applications and mini- mum content requirements. Drawings for specialized engineering disciplines (e.g. marine, civil, construction, optics, etc.) are not included in this Standard. It is essen- tial that this Standard be used in close conjunction with ASME Y14.34, ASME Y14.35M, ASME Y14.41, and ASME Y14.100. 1.2 Conventions The following conventions are guidance used in this and other ASME Y14 standards. 1.2.1 Mandatory, Nonmandatory, Guidance, and Optional Words (a) The words “shall” and “will” establish a manda- tory requirement. (b) The words“should” and “may” establish a recom- mended practice. (c) The words “typical,” “example,” “for reference,” or the Latin abbreviation “e.g.” indicate suggestions given for guidance only. (d) The word“or”used in conjunction with a manda- tory requirement or a recommended practice indicates that there are two or more options for complying with the stated requirement or practice. 1.2.2 Cross-Reference of Standards. Cross- reference of standards in the text with or without a date following the standard identity is interpreted as follows: (a) Reference to other ASME Y14 standards in the text without a date following the standard identity indicates the issue of the standard as identified in the References section shall be used to meet the requirement. (b) Reference to other ASME Y14 standards in the text with a date following the standard identity indicates that only that issue of the stand ard shall be used to meet the requirement. 1.2.3 Invocation of Referenced Standards. The fol- lowing 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. For exam- ple,“dimensioning and tolerancing shall be in accor- dance with ASME Y14.5″ is invoking the complete standard because the subject of the standard is dimen- sioning and tolerancing and no specific subject or para- graph(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 num- bers in accordance with ASME Y14.100” is only invoking the paragraph(s) on part or identifying numbers because the subject of the standard is engineering drawing prac- tices 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 for guidance only. For example, “for gaging principles, see ASME Y14.43” is only for guidance and no portion of the standard is invoked. 1.2.4 Parentheses Following a Definition. When a definition is followed by a standard referenced in paren- theses, the referenced standard is the controlling stan- dard for the definition. 1.2.5 Notes. Notes depicted in this Standard in ALL UPPERCASE letters are intended to reflect actual drawing 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 drawings. 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 text is allowed to vary to suit the application. 1.2.6 Acronyms or Abbreviations. Acronyms and abbreviations are spelled out the first time they are used in this Standard, followed by the acronym or abbrevia- tion in parentheses. The acronym is used thereafter throughout the text. 1.2.7 Units. The International System of Units (SI) is featured in this Standard.ASME Y14.24 pdf download.
