This STANDARD is approved for use by all Departments and Agencies of the DEPARTMENT of DEFENSE . 2. In implementing the Parts Specification Management for Reliability Report (PSMR-1), issued by the DEPARTMENT of DEFENSE in May 1960, it was determined that a manufacturer must provide evidence of (a) adequate production and test facilities, and (b) sound procedures for process control. This STANDARD was developed to provide guidelines.

SCOPE Scope. This STANDARD is for direct reference in established reliability and high reliability electrical, electronic, and fiber optic parts specifications and establishes the criteria for a manufacturer s qualified product system. 2. APPLICABLE DOCUMENTS General. The documents listed in this section are specified in section 3, 4, or 5 of this STANDARD . This section does not include documents cited in other sections of this STANDARD or recommended for additional information or as examples.

6 While every effort has been made to ensure the completeness of this list, document users are cautioned that they must meet all specified requirements of documents cited in section 3, 4, or 5 of this STANDARD , whether or not they are listed. Non-Government publications. The following documents form a part of this document to the extent specified herein. Unless otherwise specified, the issues of these documents are those cited in the solicitation or contract. * SAE INTERNATIONAL SAE-EIA-557 -Statistical Process Control Systems * (Copies of these documents are available online at ) INTERNATIONAL ORGANIZATION for standards (ISO) ISO 10012 - Measurement Management Systems Requirements for Measurement Processes and Measuring Equipment ISO 14644-1 - Cleanrooms and Associated Controlled Environments Part 1: Classification of Air Cleanliness ISO 14644-2 - Cleanrooms and Associated Controlled Environments Part 2: Specifications for Testing and Monitoring to Prove Continued Compliance with ISO 14644-1 * (Copies of this document are available from ) NATIONAL CONFERENCE OF standards LABORATORIES (NCSL) NCSL - Requirements for the Calibration of Measuring and Test Equipment.

Unless otherwise noted herein or in the contract, in the event of a conflict between the text of this document and the references cited herein, the text of this document takes precedence. Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained. 3. DEFINITIONS Assembly plant. A plant established by a manufacturer or operated by a distributor authorized by the manufacturer to perform specified functions pertaining to the manufacturer s identified qualified products in accordance with specified assembly procedures, test methods, processes, controls, and storage, handling, and packaging techniques.

8 Burn-in (pre-conditioning). Process of subjecting components to conditions (temperature extreme, power input extremes, etc) with the intent to either stabilize performance or significantly reduce latent defects. Calibration. A comparison result between a measuring device and a known STANDARD . Clean rooms. A clean room has a controlled level of contamination that is specified by the number of particles per cubic meter at a specified particle size. Corrective action. A documented design, process, procedure, or materials change implemented and validated to correct the cause of failure or design deficiency. Criticality. A relative measure of the consequence of a failure mode and its frequency of occurrence. Defect analysis. The process of examining technical or management (nontechnical) data, manufacturing techniques, processes, or materials to determine the cause of variations of electrical, mechanical, optical, or physical characteristics outside the established limitations.

9 Degradation. A gradual impairment and its in ability to perform. Demonstrated. That which has been measured by the use of objective evidence gathered under specified conditions. Electrical, electronic, and fiber optic parts. Basic circuit elements which cannot be disassembled and still perform their intended function, such as capacitors, connectors, filters, resistors, switches, relays, transformers, crystals, electron tubes, semiconductors, and fiber optic devices. Environmental. The aggregate of all external and internal conditions (such as temperature, humidity, radiation, magnetic and electric fields, and shock vibration) either natural or man-made, or self-induced that influences the form, performance, reliability or survival of an item. Established reliability. A quantitative maximum failure rate demonstrated under controlled test conditions specified in a specification and usually expressed as percent failures for each thousand hours or cycles of test. 2 MIL-STD-7 90G w/ CHANGE 2 Failure.

10 The event or inoperable state in which, any item or part of an item does not, or would not, perform as previously specified. Failure activating cause. The stresses, or forces, (thermal, electrical shock, vibration, etc.), which induce or activate a failure mechanism. Failure analysis. The process of examining electrical, electronic, or fiber optic parts to determine the cause of variations of performance characteristics outside of previously established limits with the end result that failure modes, failure mechanisms, and failure activating causes will be identified. Failure mechanism. The process of degradation, or the chain of events; which results in a particular failure mode. Failure mode. The abnormality of an electrical, electronic, or fiber optic part s performance which cause the part to be classified as failed. Failure rate. The total number of failures within an item population that is divided by the total number of life units expended by that population, during a particular measurement interval under stated conditions.
