3.19 Referenced Documents referenced documents: design activity standards, draw- ings, specifications, or other documents referenced on drawings or lists (ASME Y14.100).
3.20 Standard standard: a document that establishes technical criteria, methods, processes, and practices (ASME Y14.100). 3.20.1 Company Standard company standard: a document produced by a company that establishes engineering and technical limitations and applications for items, materials, processes, meth- ods, designs, and engineering practices unique to that particular company.
3.21 Standardization Document standardization document: a document developed for the purpose of standardizing items, materials, processes, or procedures (ASME Y14.100). 4 DRAWING SHEET SIZES Drawing sheet size designations are listed in Tables 4-1 and 4-2 and graphically shown in Figs. 4-1, 4-2, and 4-3. The sizes shown are the overall size of the sheets excluding protective or binding margins. See paras. 4.1.2 and 4.1.3. Rounded corners may be used on all drawing sizes.
4.1 Margins
4.1.1 Format Margins. The format margin sizes shown in applicable figures are the minimum required. NOTE: Additional design activity nonproduct definition data may be added within the drawing format margins.
4.1.2 Protective Margins. For roll size drawings, additional lengths of vertical and horizontal margins are permissible. See Figs. 4-2 and 4-3.
4.1.3 Binding Margins. The margins of basic draw- ing sizes (format margins) may be increased when the document is to be bound in a book form. Both margins may be increased when the document is to be printed back-to-back. However, except for the binding margins, all other format, content, and actual sheet size require- ments shall conform to this Standard.
4.2 Drawing Sizes All drawing sheet sizes indicated in Tables 4-1 and 4-2 are multiples oftheAsize exceptforF, H, andKsizes.
4.2.1 Roll Size Drawing Sheets. Roll size drawings are drawings that, due to their lengths, are filed in rolls. The lengths shown have been selected in recognition of microfilm frame-size requirements. Segments of length are based on two-zone increments. Segments contain full zones in each microfilm segment.
4 4.2.2 G-Size Drawing Sheets. Segments of lengths are based on multiples of 8.5 in. This format permits full-size copies to be bound in 8.5 in. by 11 in. books or filed in looseleaf notebooks. See Table 4-2 and Fig. 4-2.
4.2.3 H, J, and K Size Drawing Sheets. Segments of lengths are based on multiples of 11 in.
4.3 Computer-Generated Drawings When copies of computer-generated drawings are produced, sheet sizes may be increased to compensate for output device requirements, provided 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. The continuous lines and widths of lines shown in this Standard to form the various features (i.e., the required blocks, columns, and margins) do not have to be used. However, the format sizes and the relative positions of the data head- ings and data contents shall conform to the requirements ofthis Standard. The data headings and contents created by data processing systems shall be legible when reproduced. 5 FORMATS 5.1 Basic Basic formats include the title block from Figs. 5-1 and 5-2, and shall be used for sheet one, and may be used for all sheets of a multiple-sheet drawing. The basic formats are defined in Figs. 4-1, 4-2, and 4-3.
5.2 Continuation Sheets Continuation sheets are used for second and subse- quent sheets of a multiple-sheet drawing. See para. 6.3 for minimum title block information requirements. For continuation sheet title blocks, see Figs. 5-3 and 5-4. As an option, title blocks shown in Figs. 5-1 and 5-2 may be used. All sheets of a multiple-sheet drawing should be the same size. 5.3 Blocks The sizes of blocks specified herein are minimum. For block content, see para. 6.2. Additional blocks may be added.
5.4 Lettering The size and style of lettering printed on drawing formats shall be in accordance with ASME Y14.2.
5.5 Zoning
5.5.1 Zone Identification. Formats, except A and B sizes, shall include zones for reference purposes. Zones are indicated by alphabetical and numerical entries in format margins and by subdivisions or multiples thereof as indicated in Figs. 4-1, 4-2, and 4-3. Sizes A and B may also be zoned.
