This Standard defines decimal inch sheet sizes and formats for engineering drawings. Metric sheet sizes and format are defined in ASME Y14. 1M.
2 GENERAL Standardization of drawing sizes and the uniform location of format features on drawing forms provide definite advantages in readability, handling, filing, and reproduction. In using drawings made by other organizations, an advantage is gained when like items of information are in the same location on all draw- ings, and when uniformity of form and language is applicd in making information entrics. Revision in- formation and dates are of particular importance to users of drawings and should be located and expressed uniformly on all engineering drawings. The widespread use and exchange of microfilm and other reduced size copies of drawings both within and belween O1 ganizations emphasizes the importance of standardization of drawing sizc and format.
2.1 Units All dimensions used in this Standard are in inches. 3 APPLICABLE DOCUMENTS When the following American National Standards referred to in this Standard arc superseded by a re- vision approved by the American National Standards Institute, Inc., the superseding revision shall apply:
(a) ASME Y14.1M-1995, Metric Drawing Sheet Size and Format
(b) ASME Y14.2M-1992. Line Conventions and Lettering
(c) ASME Y14.3M-1994, Multivicw and Sectionai Vicw Drawings
(d) ASME Y14.SM-1994, Dimensioning and Tol- crancing
(e) ASME Y14.34M- 1989, Parts Lists, Data Lists, and Index Lists 4 DRAWING SHEET SIZES Drawing sheei size designations are listed in Tabies 1 and 2. The sizes shown are the overall size of the sheets excluding protcctive or binding margins. See para. 4.1. Rounded corncrs may bc uscd on all draw- ing sizes.
4.1 Margins The margin sizes shown in applicable figures are the minimum required.
4.1.1 Protective Margins. For roll size draw- ings, additional lengths of vertical margins of 2 in. minimum on both cnds arc permissible where nec- essary for handling and storage. See Figs. 2 and 3.
4.1.2 Binding Margins. The margins of basic drawing sizes may be increased if the document is to be bound in a book form. Both margins may be in- creased if the document is to be printed back to back.
However, except for the binding margins, all other format, content, and actual sheet size requirements are to conform to this Standard.
4.2 Drawing Sizes All drawing sizes indicated in Tables 1 and 2 are multiples of the A size except for F, H, and K sizes.
4.2.1 Standard Roil Size Drawings. Roll size drawings are drawings, which, due to their lengths, are filed in rolls. The lengths shown for all roll size drawings have been selected in recognition of micro film frame size requirements. Segments of length are based on tWo zone increments. Segments contain full zones in each microfiim segment. Match lines always fall on a zone mark.
4.2.2 G-Size Format. Segments of iengths are based on multiples of 8.5 in. for G-size format. The G-size format permits full size copies to be bound in 8.5x 11 in. books or filed in looseleaf notebooks. See Table 2 and Fig. 2
4.2.3 H, J, and K Size Format. Segments of length are based on multiples of 11 in. for H,J. and K size formats. 4.3 Computer-Generated Drawings
4.3.1 Computer Aided Design (CAD). When copies of CAD drawings are produced, sheet sizes may be increased to compensate for output device requirements, providing the copies can be trimmed to the sheet sizes specified in this Standard. However, the drawing format and content shall conform to the requirements of this Standard.
4.3.2 Drawings Prepared in Data Processing Systems Word or Text and Graphics Process- ing). Data processing systems other than CAD may be used in preparing A and B size drawings. The continuous lines and widths of lines that are rcquired by this Standard to form the various features (that is, the required blocks, columns, and margins) do not have to be used. However, the format sizes, the rel- ative positions of the data headings and data contents shall conform to the requirements of this Standard. T he data headings and contents created by other data processing systems shall be legible when reproduced.
5 BASIC FORMATS Basic sheet formats are drawing sheets that include the title block from Figs. 4 or 5, and shall be used for sheet one, and may be used for all sheets of a . multisheet drawing. See para.ASME Y14.1 pdf download.ASME Y14.1-1995 pdf free download
