ASME Y14.1 pdf free download Drawing Sheet Size and Format Engineering Product Definition and Related Documentation Practices
1 GENERAL1.1 Scope
This Standard defines sheet sizes and formats for engi-neering drawings. Both metric and decimal-inch sheetsizes and formats are included. For engineeringproduct definition preparation and practices, see ASMEY14.100.
1.2 Purpose
Standardization of drawing sheet sizes and uniformlocation of format features on drawing forms providesdefinite advantages in readability, handling, filing, andreproduction of engineering drawings. When usingdrawing sheets made by other organizations,an advan-tage is gained when like items of information are inthe same location on all drawing sheets, and when unifor-mity of form and language is applied in making informa-tion entries. Revision information and dates are ofparticular importance to users of drawings and shouldbe located and expressed uniformly on all engineeringdrawings.
The widespread use and exchange of reduced-sizecopies of drawing sheets, both within and between organ-izations, emphasizes the importance of standardizingdrawing sheet size and format.
1.3 ASME Y14 Series Conventions
The conventions in paras.1.3.1 through 1.3.9 are used inthis and other ASME Y14 standards.
1.3.1 Mandatory,Recommended,Guidance, andOptional Words
(a) The word “shall” establishes a requirement.(b The word”will” establishes a declaration ofpurpose on the part of the design activity.
(c) The word “should” establishes a recommendedpractice.
(d) The word “may” establishes an allowed practice.ey The words “typical,””example,””for reference,” andthe Latin abbreviation “e.g.” indicate suggestions given forguidance only.
The word “or” used in conjunction with a require-ment or a recommended practice indicates that there aretwo or more options for complying with the statedrequirement or practice.
(g) The phrase “unless otherwise specified” or “uos”shall be used to indicatea default requirement.The phraseis used when the default is a generally applied require-ment and an exception may be provided by another docu-ment or requirement.
1.3.2 cross-Reference of Standards. Cross-referenceof standards in text with or without a date followingthe standard designator shall be interpreted as follows:(a) Reference to other ASME Y14 standards in the textwithout a date following the standard designator indicatesthat the issue of the standard identified in the Referencessection (section 2] shall be used to meet the requirement.(b] Reference to other ASME Y14 standards in the textwith a date following the standard designator indicatesthat only that issue of the standard shall be used tomeet the requirement.
1.3.3 Invocation of Referenced Standards.Thefollowing examples define the invocation of a standardwhen 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 withno limitations to a specific subject or paragraph(s) of thestandard, the entire standard is invoked. For example,”dimensioning and tolerancing shall be in accordancewith ASME Y14.5″is invoking the complete standardbecause the subject of the standard is dimensioningand tolerancing and no specific subject or paragraph(s)within the standard are invoked.
(b) when a referenced standard is cited in the text withlimitations to a specific subject or paragraph(s) of thestandard, only the paragraph(s) on that subject isinvoked. For example, “assign part or identifyingnumbers in accordance with ASME Y14.100″is invokingonly the paragraph(s) on part or identifying numbersbecause the subject of the standard is engineeringdrawing practices and part or identifying numbers area specific subject within the standard.
(c) when a referenced standard is cited in the textwithout an invoking statement, such as “in accordancewith,” the standard is invoked for guidance only. Forexample, “for gaging principles, see ASME Y14.43”isonly for guidance and no portion of the standard isinvoked.
1.3.4 Parentheses Following a Definition. when adefinition is followed by a standard referenced in parenth-eses, the standard referenced in parentheses is the sourcefor the definition.
