(Ix) identification marking requirements.
(i) required processes.
&) test requirements and procedures.
(k) any other information required to fully describe the item.
15.8 Matched Set Drawing
15.8.1 Description. A matched set drawing delineates items that are matched and for which replacement as a matched set is essential. A matched set drawing establishes item identification. See Fig. 15-7.
15.8.2 Application Guidelines. A matched set drawing is prepared when the required dimensions, tolerances, or other characteristics of items can he specified only in terms of the matched relationship. This includes items that are interchangeable only as a set because of special requirements for machining, electrical characteristics, performance, etc. Under such conditions, a matched set drawing defines the matching relationship. Individual parts of the set may be delineated by the matched set drawing or by other drawings.
15.8.3 Requirements. The matched set drawing includes, as applicable
(a) the physical or functional mating characteristics of the matched items, i.e., set
(b) the PIN assigned to each of the parts and to the matched set
(c) discrete identification marking of the matched set
(d) the statement FURNISH ONLY AS A MATCHED SET or similar note
159 Contour Definition Drawing
15.9.1 Description. A contour definition drawing contains the mathematical, numeric, or graphic data elements used to describe a contoured surface. It establishes identification for the contoured surfaces delineated thereon. A contour definition drawing is a type of ancillary drawing. See para. 1.9 and Figs. 15-8, 15-9, and 15-10.
15.9.2 AppLication Guidelines. A contour definition drawing is prepared to define complex surface geometry that cannot be conveniently included in the detail drawing(s) of an item. Due to the complexity of a surface, the contour definition drawing may define two or more item surfaces on the same drawing.
15.9.3 Requirements. A contour definition drawing includes, as applicable
(a) mathematical equations for the contoured surface.
(b) tabulated coordinates point values. The spacing of these points is dependent upon the desired degree of curvature and the surface tolerance.
(c) graphic sections.
(d) a summary of features and relationships to more basic coordinate systems in appropriate combinations to define the contoured surface or the desired points on a contoured surface.
15.10 Software and Memory Device Data
Drawings defining software such as instructions, or data that will be or is intended to be resident in a memory device or other type of media that becomes a part of the end item, shall be prepared as either a software installation drawing or altered item drawing, determined by whether the software is one-time programmable or multiprogrammable. See Fig. 15-11.
15.10.1 Memory Device Categories. For purposes of this Standard, memory devices are categorized as being either one-time programmable or multiprogrammable.
(a) One-time programmable devices shall be documented using the requirements of the altered item drawing (see para. 8.1).
(b) Multiprogrammable devices shall be documented using the requirements of the software installation drawing (see para. 15.10.2).
15.10.2 Software Installation Drawing
18.104.22.168 Description. A software installation drawing identifies the characteristics of the software, instructions for programming into the memory device, and its master media and physical location. Software programs will be identified by a PIN within the drawing form rather than defined using truth tables. This drawing does not establish item identification. See Fig. 15-11.
22.214.171.124 Application Guidelines. A software installation drawing is prepared when it is necessary to define the characteristics of the software, instructions for programming into a memory device, and its master media and physical location.
126.96.36.199 Requirements. The drawing shall identify
(a) the item to be programmed by PIN by referencing the original vendor’s PIN or by providing a complete description of the item, or by vendor item control drawing or source control drawing if a nationally recognized standard is not available
(b) the PIN of the software, software version, and other characteristics such as operating system and ‘ersion, programming language used, source file identification and version, and object file identification and version.
