ASME Y14.1M:2012 pdf free download.Metric Drawing Sheet Size and Format.
ASME Y14.1M defines metric sheet sizes and formats for engineering drawings. Decimal inch sheet sizes and format are defined in ASME Y14.1. For engineering drawing preparation and practices, see ASME Y14. 100.
1.2 Purpose
Standardization of drawing sheet sizes and the uniform location of format features on drawing forms provides definite advantages in readabiitv handling, filing. and reproduction. In using drawing sheets made by other organizations, an advantage is gained when like items of information are in the me kwation on all drawing sheets, and when uniformity of form and language is applied in making information entries. Revision information and dates aie of particular importance to users of drawings and should Lw located and espressed uniformly on all engineering drawings.
The widespread use and exchange of reduced-size copies of drawing shctls both within and between organizations emphasizes the importance of standardization of drawing sheet size and format.
1.3 ASME Y14 Series Conventions
The following conventions are guidance used in this and other ASME Yl4 writ-s staitdards
1.3.1 Mandatory, Nonmandatory, Guidance, and Optional Words
(a) The word shall” establishes a mandatory
requirement.
fit) The word “will” establishes an intended, mandatory requirement.
(c) The words “should” and “may” establish a nonmandatory’ practice.
Id) The words “typical”“esample.”“for reference,” or the Latin abbreviation “e.g.” indicate suggestions given for guidance only.
(e) When 11w test of this Standard has an “or” statement, it indicates that there are two or more options on how to comply with the stated requirement.
7.2 Contents
The reu.sion history block provides space for revision symbol, description, or Identification of the change authorization document, date, and approvals. The headings shall be presented as shown in Fig. 7-I. The zone column may be added when zones arc included in the drawing format and the design activity desires to identify locations of revisions The width of the revision history block may be changed to provide for other columns as n vsary. See ASME Y14.35M for completion requirements.
8 REVISION STATUS OF SHEETS BLOCK
A revision status of shcvts block is required on sheet one of multiple-sheet drawings and records the revision status of each sheet. The revision status of sheets block is shown as a tabulation similar to those shown in Fig. H-I.
The reviskn si.tus of sheets block may he located in the area of the revision history block or the title block, or on a separate sheet for drawings in book form.
See ASME Y14.35M for completion requirements
When all sheets of multiple-sheet drawings are maintained at the same revision level, the revision status of sheets block may be omitted. A note located near the title block shjll state all sheets are maintained at the same revision level.
9 ASSOCIATED LISTS
See ASME Yl 434 for shvct sizes and formats of assod. ated lists.
10 ADDITIONAL DATA BLOCKS
Blocks containing various types of additional data, when required. shall be added adlacent to the title block and in the same respective location on all drawing sheets.
When drawing size restricts placement of optional block(s), the block(s) may be located where space permits.
The following subparagraphs identify several Commonly used blocks. Additional blocks may be added when required.
10.2 DimensIoning and Tolarancing Block
Inlorniat ion relative to dimen.’uoning and tolerancing. such as angular and dimensional tolerances, are given in this block. See Fig. 10-1. Reference to ASME Y145 may be included In this block. When used, the block shall be in the title block area.
10.3 ApplicatIon Block — Optional
When used, the apphcation black shall be located adjacent to the title block. The application block includes columns such as next assembls “NEXT ASSY, and where used. USED ON.’ for drawings depicting a detail part or assembly of a component for a larger unit. See Fig. 10-2. The NEXT ASSY’ column lists drawing number(s) or part numhers) of the next higher assernbly(ies) to which the item(s) applies. The “USED ON” column identifies the system or subsystem to which the item pertains. As an alternative, reference may be made to application data in a separately maintained document or database. See ASME Yl4.34.
