Civillery : Engineering Drawing Standard Manual

Civillery Zone, In this week we share about Drawing Standard Manual, if you want to know more details click download, for download this file. This drawing standards manual establishes the conventions to be adhered to by engineering and drafting personnel in the preparation, revision, and completion of engineering drawings. This manual sets forth the minimum requirements acceptable at GSFC for the preparation of engineering drawings for flight hardware and ground support systems.

Standard Drawing Size

The requirements specified herein are essential to the standardization of practices and to a uniform interpretation of drawings. A system, payload, or component assembly shall be completely defined by means of drawings, including lists, schematics, wiring diagrams, and specifications, to ensure that components fabricated are in accordance with the design. The documentation information shall serve as a permanent record. Flight hardware shall be fabricated in accordance with the approved design documents. These documents shall reflect the characteristics and acceptance criteria for all materials, component/parts, subsystems, and the complete system. The acceptance criteria for parts and materials shall be specified by standard specifications when applicable. Engineering drawings are defined as those drawings that communicate the requirements for the manufacture of the end-product items, their assembly, and their installation in the end product.

Standard Drawing Line

General information for the selection or development of a drawing title is as follows:

1. The title should be as brief as possible but should contain sufficient information to categorize the part properly and to distinguish it from other similar parts.
2. The drawing title shall consist of the following :

• Identifying noun or noun phrase.
• The most significant modifier or modifying phrase.
• The next most significant modifier or modifying phrase.

The noun or noun phrase establishes a basic concept of an item. The modifiers serve to narrow the area of concept established by the basic name. A modifier is separated from the noun or noun phrase by a comma and from any preceding modifier by a comma. The type designator and/or any additional modifiers required to further identify an item are separated from the first part of the title by a dash. Where applicable, the word “ASSEMBLY” shall be used as the last word of the noun phrase.
EXAMPLES:
“Beam, Hoisting, Guided Missile”
“Cover, Protective, Rocket Motor—Forward Section”
“Cabinet, Electrical Equipment—CY-147”
“Transportation—Dolly Assembly, Earth Satellite” 

1. The noun, or noun phrase, is never abbreviated. Abbreviations are used in the modifiers only when space is limited. When used, abbreviations shall conform to Abbreviations, paragraph 2.2 on page 12.
2. When one drawing supersedes another, the new drawing, when practical, has the same title.
3. Parentheses are not used to enclose any portion of the drawing title.
4. Program names (or abbreviations) should be added to the “Used On” block and not the Title block; exceptions are on the final or top assembly drawing.
