What is ISO 14621-2 - Electrical, electronic electromechanical (EEE) parts about ?
ISO 14621-2 establishes technical guidelines for developing and documenting an electrical, electronic, and electromechanical (EEE) parts control program, to assure that the parts used in the flight hardware are acceptable and possess adequate functional, radiation, and reliability characteristics to meet the system requirements. The family of EEE parts includes electro-optical parts.
ISO 14621-2 identifies a set of management guidelines for dealing with space systems engineering activities and defines the minimum existing processes on the subject.
These guidelines are tailorable to the needs of each programme based on the project performance criteria, risk tolerance, budget, mission duration, environment, schedule, and other considerations. ISO 14621-2 applies to all customers and suppliers furnishing flight hardware and is suitable for reference in proposal instructions.
ISO 14621‑2 is designed to assist the user and supplier communities in developing and executing an effective process for the design, selection and application of electrical, electronic, and electromechanical (EEE) space parts throughout the life cycle of the programme.
ISO 14621‑2 is tailored to meet the specific needs of each individual programme, i.e., to address the applicable system performance requirements, risk tolerance, budget, mission duration, operating environment, and schedule. Tailoring should result in a set of planned activities that are not only capable of achieving all contractual EEE parts related requirements but also commensurate with the space system’s unit-value/mission-criticality and life cycle technical data product requirements.
ISO 14621‑2 is relevant to all users and customers of space systems, and the suppliers and vendors that furnish space flight hardware. However, to utilize these documents to their fullest potential, it is necessary to understand the commercial space business environment which has unique cost and schedule constraint challenges.
Who is ISO 14621-2 - Electrical, electronic electromechanical (EEE) parts for ?
ISO 14621-2 on electrical, electronic electromechanical (EEE) parts for aerospace applications is applicable to:
- Manufacturers of electromechanical
- Aircraft manufacturers
- Quality control/testing and compliance personnel for aerospace
- Spacecraft and space products manufacturers
- Aerospace and defence industries
- Design engineers for electromechanical parts
Why should you use ISO 14621-2 - Electrical, electronic electromechanical (EEE) parts ?
EEE part is a device that performs an electrical, electronic, electromechanical (EEE) function, including electro-optical devices. EEE consists of one or more elements joined together such that they cannot be dissembled without destroying the functionality of the device. Electromechanical parts are a combination of electrical and mechanical components used in complex circuitry.
ISO 14621-2 provides you with the technical guidelines for parts control programme tasks applied throughout all phases of flight hardware development, manufacturing, and logistic support.
ISO 14621-2 describes the process for selection and standardization of the parts and also includes the approach for technology insertion and the methodology and rationale for selection of parts manufacturers and service companies.
What’s changed since the last update ?
BS ISO 14621-2:2019 supersedes BS ISO 14621-2:2003. BS ISO 14621-2:2019 includes some technical changes concerning BS ISO 14621-2:2003. These include:
