IEC TC 107: PROCESS MANAGEMENT FOR AVIONICS

IEC TC 107YOUR STRATEGIC TOOL IN PROCESS MANAGEMENT FOR AVIONICS

3

Your company needs to:

■ Develop, document, and implement processes to manage electronic components that meet the requirements of the Avionics industry (quality, reliability, safety, ...) while the electronics industry is dominated by high-volume applications, rapid change, obsolescence and wear out problems.

IEC TC 107 has a major role to play in developing standard processes to use and manage these components, equipments, and systems in Avionics applications.Participating in the work of IEC TC 107 can help you tackle issues such as atmospheric radiation requirements or lead free transition.

THE WORK OF IEC TC 107

IEC Technical Committee 107 was set up in 2001 to develop process management standards on systems and equipment used in the fi eld of Avionics. Avionics comprises electronics used in commercial, civil and military aerospace applications, requiring particularly high reliability level and long life duration.

Nineteen IEC National Committees are taking part in the work of TC 107:

Eight Participating or P members: China, France, Germany, Japan, Korea, Spain, the United Kingdom and the United States of America.

Eleven Observers or O members: Belgium, Denmark, Finland, Greece, Israel, Italy, Netherlands, Czech Republic, Norway, Sweden and Switzerland.

Particular processes are developed in correlation to support the Electronic Component Management Plan (ECMP) development: radiative environment, lead-free transition, obsolescence, and so forth.

How standards are prepared:

The TC 107 Working Groups (WGs) prepare technical documents in the fi eld of process management for Avionics, which are then submitted to the full member National Committees for voting with a view to their approval as International Standards. All IEC Publications are subject to a maintenance cycle appropriate to the technology evolution. New topics can be considered with regards to the market and technologies trends.

Experts from China, France, Germany, the United Kingdom and the United States of America are involved in the work of several TC 107 Working Groups:

■ Maintenance Team 1 (MT 1): Electronic component management plans (IEC 62239 series)

■ Project Team (PT) 62396: Accommodation of atmospheric radiation effects via single event effects within avionics electronic equipment

■ WG 1: Aerospace and defense electronic systems containing lead-free solder

■ WG 2: Aerospace qualifi ed electronic component (AQEC)

■ WG 3: Counterfeit electronic parts; Avoidance, Detection, Mitigation, and Disposition in Avionics Applications

In view of the increasing problems caused by the counterfeiting of electrical and electronic components, equipment and systems, IEC TC 107 established a new working group whose main responsibility is to give guidance for the development of a management plan to avoid the use of counterfeit electronic parts in avionic applications. Counterfeiting prevention in a developing worldwide electronic component market is essential for avionics applications, with regards to reliability and safety requirements.

IEC/TR 62240, Process management for avionics - Use of semiconductor devices outside manufacturers’ specifi ed temperature range

IEC/TS 62396, Process management for avionics - Atmospheric radiation effects■ Part 1: Accommodation of atmospheric radiation effects via single event effects within avionics electronic equipment■ Part 2: Guidelines for single event effects testing for avionics systems

■ Part 3: Optimizing system design to accommodate the single event effects (SEE) of atmospheric radiation■ Part 4: Guidelines for designing with high voltage aircraft electronics and potential single event effects■ Part 5: Guidelines for assessing thermal neutron fl uxes and effects in avionics systemsThe revision/extension of all parts is underway.

IEC/TS 62500, Process management for avionics - Defi ning and performing highly accelerated tests in aerospace systems - Application guide

IEC/TS 62564-1, Aerospace qualifi ed electronic component (AQEC) - Part 1: MicrocircuitsThe revision to include semiconductors is underway.

Work in progress

IEC TC 107/WG 1 is going to convert the current Part 1and Part 2 into standards and to develop four new documents dealing with lead-free electronics.

IEC TC 107/WG 3 is starting to develop one document dealing with electronic counterfeiting prevention.

Publications from other IEC TCs

Two IEC TCs have developed publications that are relevant to the work of IEC TC 107.

TC 47: Semiconductor devicesIEC PAS 62435, Electronic components - Long-duration storage of electronic components - Guidance for implementation

TC 56: DependabilityIEC/TS 62402, Obsolescence management - Application guide

The World of IEC

The IEC is the world leading organization that prepares and publishes International Standards for all

electrical, electronic and related technologies – collectively known as “electrotechnology”. The IEC

also administers three global conformity assessment systems, IECEE, IECEx and IECQ, for testing,

certifi cation and approval of equipment, systems and components to its International Standards. Wherever

you fi nd electricity – from generation, transmission and distribution, through industrial automation,

healthcare, transport, multimedia in the home, to the battery in your phone – you will fi nd the World of IEC

supporting the environment, safety, performance and effi ciency.
