MIL-STD-1546B

Abstract

This standard establishes the requirements for the preparation, implementation, and operation of a parts, materials, and processes control program for use during the design, development, and production of space and launch vehicles. The implementation of these requirements is intended to: <br>a. Assure integrated management of the selection, application, procurement, control, and standardization of parts, materials, and processes (PMP). <br>b. Improve the reliability of program PMP to reduce PMP failures at all levels of integration, assembly, and test. <br>c. Reduce program life cycle costs. <br>d. Improve procurement and test of small quantities of piece parts and materials that meet system requirements. <b><u>Intended Use:</u></b> The standard is intended for use in acquisition contracts for space vehicles, upper stage vehicles, payloads, launch vehicles, and for their subtier equipments. This standard should be cited in the contract schedule, or the statement of work, to specify the requirements for the parts, materials, and processes management, standardization and control program for applicable equipment. Note that this standard is not an appropriate reference in any specification since it is a management standard and does not contain technical requirements for the parts, materials, and processes to be used in the equipment. All requirements for data delivery must be listed in the Contract Data Requirements List of the acquisition contract. There may be acquisition contracts for other types of equipment requiring high reliability where the special parts, materials, and processes control requirements stated in this standard should be applied. For those acquisition contracts, this standard may be cited to specify the applicable requirements. However, a statement should be included in the contract or the statement of work indicating that the words "space and launch vehicle" in this standard are to be interpreted as the applicable equipment. The requirements in this standard should therefore be interpreted as applying to the parts, materials, and processes control program requirements for the acquisition of the applicable equipment. The requirements in the text of this standard expand the applicable Parts Control Program requirements as stated in MIL-STD-965 in order to satisfy space and launch vehicle acquisition requirements. This standard also expands the requirements to apply to materials and processes. Contracts for ground equipment (e.g., control segments and user segments of space systems) could apply MIL-STD-965 for those segments unless it is determined that a tailored application of this standard would be more appropriate for the reliability or standardization objectives of the program. Note that many space and launch vehicle acquisition contracts include both space and ground equipment, so if both MIL-STD-965 and this standard are referenced, care should be taken to ensure that the applicability of each document is clear. In addition to this standard other critical management requirements to be implemented in the statement of work may include requirements for: a. Quality program (MIL-STD-1586, MIL-STD-1535, MIL-STD-1520, and MIL-Q-9858) b. Reliability program (MIL-STD-1543) c. Contamination Prevention and Control program (MIL-STD-1246) d. Safety program (MIL-STD-882 and MIL-STD-1574) e. Hardness and Survivability program, if applicable (DOD-STD-1766) f. Program reviews (MIL-STD-1521) Critical technical requirements to be implemented in the equipment specifications may include: a. PMP technical requirements for space and launch vehicles (MIL-STD-1547) b. DPA technical requirements for parts (MIL-STD-1580) c. Corrosion control requirements for materials (MIL-STD-1568) d. Electrostatic discharge control program (MIL-STD-1686 and DOD-HDBK-263) e. Electrical and electronic equipment design (DOD-E-8983, DOD-W-83575, and MIL-STD-454) f. Moving mechanical assembly design (MIL-A-83577) <br>
