It is Superceded for all future projects and replaced by Global Design Standards. 1. PURPOSE This standard aims at correc
3、tly conveying the contents of drawing revisions resulting from a variety of reasons, such as the quality improvement, productivity enhancement and cost and weight reduction, and keeping the reasons and history of drawing revision. 2. SCOPE 2.1. This standard applies to product drawings (hereinafter
4、called “drawings“) released to the Engineering Change Procedures, and may also apply to the layout and package drawings. 2.2. It applies to cases where any letters and figures in the drawing are changed, added, deleted or re-generated. 3. TYPES OF DRAWING REVISION 3.1. Revision of drawing : when the
5、 original drawing is changed as follows: 3.1.1. Change in drawing contents 3.1.2. Addition of drawing contents 3.1.3. Deletion of drawing contents 3.2. Remaking of drawing : when a drawing is redrawn while keeping the previous drawing number 3.2.1. Redrawn with change 3.2.2. Redrawn without change 4
6、. NOTES IN DRAWING REVISION 4.1. Revision shall be made in conformity with the latest drawing standards. 4.2. Relations with other parts, development, assembly, maintenance and other overall effects shall be reviewed fully and carefully. 4.3. The original drawing shall not be damaged and the un-revi
7、sed portions shall not be erased. 4.4. The type of letters and the thickness of lines shall be as similar to the original drawings as possible. 4.5.

In the following cases, the revised drawing shall have a new part number or drawing number, not the existing part number or drawing number. 4.6.1. When performance or durability is influenced to an ex
9、tent that existing parts must be scrapped in order to ensure safety or to supplement insufficient function. 4.6.2. When full compatibility with the existing part is not ensured after revision in terms of performance and mounting condition due to changes in part dimensions, material or other characte
10、ristics. 5. REVISION METHOD 5.1. Order of revision registration 5.1.1. Revisions shall be registered from the bottom to the top of the revision table. When the revisions are made frequently to fill up the revision blocks, a new drawing is to be made in principle. 5.1.2. When revisions ought to be re
11、gistered in the same drawing for special reasons, they shall be continued in new blocks just left to them from the left top to the bottom as shown in Fig. 1. Fig. 1. Order of revision registration 5.2. Drawing revision table 5.2.1. All blocks in the revision table shall be filled. Blocks not requiri
12、ng entering shall be filled with a dash or vertical line. 5.2.2. In case a number of revision items occur at the same time, or when the recording must be made through several lines, the date, sign, and ECR number are entered only at the top line and a vertical line is drawn throughout related column

In case of revision from PROTO EPI RELEASE to PROTO RELEASE, from PROTO RELEASE to PRODUCTION EPI RELEASE, and from PRODUCTION EPI RELEASE to PRODUCTION REL
16、EASE, drawings shall be released after contents of revision is arranged in the revision table in principle. Drawing revision history may be left intact for special purposes (Ex: When working method and drawing revision history are required due to production line installation, part manufacturing proc
17、edure, etc.). Note) EPI : ENGINEERING PRELIMINARY RELEASE Fig. 3.

24、 at the changed position in the drawing shall be indicated inside a circle. d=8.0mm when h=3.5mm d=10.0mm when h=5.0mm 5.6.2. The revision symbol shall be indicated outside the part outline as long as possible and not be overlapped with other letters. 5.6.3. A revision symbol shall be indicated at o
25、ne place on a drawing in principle. When the same content is revised at several places on a drawing, it shall be entered just once in the revision record column, and the revision symbol shall be indicated at each revised portion. For example, “SURFACE TEXTURE SPEC. ADDED, 5 PLACES“ is recorded in th
26、e drawing revision record column, and the revision symbol is indicated at five places where surface texture specification is added. 5.6.4. When a revision requires correction of several places in a drawing, the revision symbol is indicated at one most easily recognizable place. d5 h EDS-A-1007DRAWIN
