DRAWING REQUIREMENTS MANUAL

active, Most Current
Organization: DRM
Publication Date: 1 January 2008
Status: active
Page Count: 1,218
scope:

This 11th Edition of the Drawing Requirements Manual (DRM) contains instructions for the preparation of engineering drawings and models based on ASME Y14.100, ASME Y14.5M-1994, ASME Y14.41-2003, and many other standards and specifications for commercial applications, and MIL-DTL-31000 for Department of Defense (DoD) and other government applications. MIL-DTL-31000 invokes applicable specifications and standards for a Technical Data Package (TDP), which may contain both commercial and military specifications and standards. The DRM also recognizes a number of internal company practices not covered by any such documents.

While these practices are generally acceptable to Industry and to DoD, any given contract may invoke peculiar customer requirements. In that case, the contract requirements must be given precedence.

Drawing and annotated model examples are complete only to the extent necessary to illustrate the requirements of the accompanying text.

Comments and suggestions for improving this DRM are welcome and solicited by the publisher.

Comment on the above by Jerome H. Leiblich:

The question most often asked about the use of this DRM and can occur in any section being asked about, is "What published government or industry specification or standard was the information or procedure that is described in this DRM extracted or quoted from?" The answer is often "NONE". The reason being that the subject has been treated, too vaguely or has been left entirely to the discretion of the design activity. When that occurs, the author has reviewed the particular procedure required to produce an acceptable drawing of at least ten (10) major prime contractors' internal Drafting Room Manuals and has presented in this DRM the majority opinion of all to describe the subject. The fact that these contractors have done, and are doing business with their commercial or government customers gives credence to their procedures.

A typical example would be the application of a Parts List (PL) whether it is integral or separate from the drawing. Government and Industry specifications instruct and invoke the Parts List (PL) requirement but, do little in the way of what the Parts List size and columns other than what columns are mandatory. This DRM has established the information that is lacking but still makes the statement that the choice remains with the individual company when no published government or industry specification or standard covers the procedure or that the contract or purchase order specifically states a procedure to be used for that particular set of drawings.

Comment on the 11th Edition by Bryan R. Fischer:

The revisions made in Sections 1 - 25 and appendices of the DRM, and the new material in SECTION 26 was developed with the same goal as the rest of the DRM: to explain what is in the applicable standards, to explain how to apply the applicable rules and techniques, to clarify the material in the applicable standards, and to add additional rules and requirements where needed.
