The Aerospace and Defence Industries Association of Europe - Standardization (ASD STAN), is an association which establishes, develops and maintains standards on behalf of the European Aerospace & Defence industry. ASD-STAN publishes and sells online its own standards-library documents for products, quality systems and product support for the European aerospace industry.

ASD-STAN was formerly known as the Association of European Aircraft and Component Manufacturers Standardization; Association Européenne des Constructeurs de Matériel Aérospatial Normalisation (AECMA-STAN).


The roots of ASD-STAN date back to the early 1970s when the members of the former AECMA decided to create a group of experts for technical standards’ development (AECMA CN). Since 1973 this group cooperated with CEN (Comité Européen de Normalisation - European Standards Organisation) providing its technical standards for publication by CEN as "EN" European Standards. Following its later registration in Belgium as international non-profit association, in 1986 AECMA-STAN was officially recognized by CEN as "Associated Body" and "sole provider of aerospace standards".

In 2004, the Association of European Aircraft and Component Manufacturers, AECMA, merged with two other European aviation organizations (European Defence Industries Group, (EDIG) and EUROSPACE) and became ASD, the Aerospace and Defence Industries Association of Europe. In parallel this was performed for ASD-STAN.

The term "ASD" was often synonymous with those developed by this organization specifications "ASD Spec 1000D", "ASD Spec 2000M" and "ASD Simplified Technical English" (see links below).


ASD-STAN is interactively cooperating with various European and international organisations in the standardization area of the Aerospace and Defence sector.

ASD-STAN acts as CEN Technical Committee for Aerospace and transfers all of its projected EN standards prEN to the CEN publication process to become a European Norm (EN).

At the European level ASD-STAN collaborates with ASD, EAQG, EASA and EUROCAE and - on defence related standardization - in the aerospace sector with EDA.

At international level ASD-STAN has some common projects with AIA and SAE to produce common standards. It is well recognised as the European body for the development and publication of global aerospace standards of the 9100-series by the International Aerospace Quality Group (IAQG). ASD-STAN collaborates with different ISO Technical Committees in the Aerospace (ISO TC20), Material sector (ISO TC79, TC155) and Automation systems (ISO TC184).

At the defence sector, ASD-STAN is part of the EDA Joint Maintenance Group for maintenance of the EDA European Defence Agency EDSTAR/EDSIS system with Aerospace related topics. ASD-STAN supports the CEN Defence Standardisation Coordination Group (DSCG) to provide standards on request of identified needs in the Aerospace sector and has a cooperation agreement with NATO.

ASD-STAN product related standards are used for certification by ASD-CERT against the requirements of prEN9133/EN9133 “Aerospace series – Quality management systems – Qualification Procedure for Aerospace Standard Parts”.

ASD developments related to standard documents are mirrored by ASD-STAN and published as ASD-STAN prEN documents, following the general ASD-STAN development and publication process.

Standard Developments and Publications[edit]

ASD-STAN developments are published as Technical report (TR) or projected European Norm (prEN). The prEN abbreviation is often seen as preEN, but is not to be compared with the CEN prEN.

Over the years, ASD-STAN has established a lean and streamlined standardisation process for European aerospace standards in agreement with the European Committee for Standardization (CEN). It follows the principles of openness, transparency and consensus required by the Regulation on European Standardization (1025/2012[permanent dead link]). However, reducing the lead-time for the standards development process in accordance with industry needs remains a constant goal of ASD-STAN. The process is described in detail in the ASD-STAN General Process Manual. The general drafting, balloting and publication time for an ASD-STAN prEN is 12 months and includes the steps:

- New Work Item (NWI) Proposal and Agreement

- Drafting Process

- Ballot and Review Process

- Finalizing draft standard by updating and formatting

- Publication as prEN

With 2213 ENs – which is 11% of the available EN-Standards in Europe - ASD-STAN is one of the major providers of European Norms. In addition 808 prENs and 64 Technical Reports are already published by ASD-STAN which will be transferred to European Norms in the near future. Currently there are 672 standard developments by around 450 involved experts of the European aerospace industry (Data from 06/2016).

In 2015 ASD-STAN published 80 new projected European Norms (ASD-STAN prEN), in addition to finalize the transformation of 115 prEN to European Norms (EN).


The European aerospace industries are represented by the national industrial associations or European organizations as members of ASD-STAN. This approach enables each industrial partner, especially SMEs, to participate at the various ASD-STAN standardization activities.

Areas covered by D6 Quality

D6 Domain “Quality” covers the development and maintenance of all quality-related documents in the area of product assurance and quality management. It may cover the document development of product assurance management, Quality Management, Quality Assurance, Safety Assurance, Reliability, Availability and Maintainability Assurance, Software Product Assurance. It defines their respective objectives, policies, requirements and implementation standards to achieve the stated overall “Quality” and “Product Assurance” objectives throughout the complete life cycle of the products.

The domain covers mainly the activities of the International Aerospace Quality Group “IAQG” and represents the European sector (EAQG) of IAQG to achieve and involve a European position on the IAQG developments. IAQG develops standards, partly as extension to existing quality management systems, to implement initiatives that make significant improvements in quality and reductions in cost throughout the value stream by establishing and maintaining dynamic cooperation, based on trust, between international aerospace companies. The objectives of IAQG, covered in the ASD-STAN domain, are:

  • Establish commonality of aviation, space and defence quality systems, “as documented” and “as applied”
  • Establish and implement a process of continual improvement to bring initiatives to life (e.g. Industry expectations, lean manufacturing, performance metrics)
  • Establish methods to share best practices in the aviation, space and defence industry
  • Coordinate initiatives and activities with regulatory/government agencies and other industry Stakeholders, aiming at the consideration of respective standards as acceptable means of compliance.

Under the umbrella of the ASD Airworthiness Committee and mirrored by ASD-STAN for the standard development and publication process, a set of standards for Design Organization Approval were developed to become European Norms and one Acceptable Means of Compliance with EASA DOA requirements. Design Organization Approval (DOA) holders impose to their design suppliers too many different and often complex sets of requirements for the same topic. A common set of requirements are prepared within Aerospace Industry, EASA and EAQG. It shares with EASA the global objectives of “Simplification” by e.g. minimum requirements, more guidance materials) and creation of Industry Standards.

Areas covered by D7 eBusiness standards

This domain is performed by the ASD Strategic Standardization Group (SSG).

The SSG is a group of European manufacturers, A& D associations and military governmental agency in order to share efforts of development of common A&D e-Business standards and associated harmonized European policies for operational use.

Both are understood today as two strategic levers of competitiveness for all the A&D manufactures and their supply chains (New role of the Original Equipment Manufacturer as System Integrator, and product & process Information Integrator).

The ASD SSG does not aim to create new eBusiness standards but to support effective governance at European level of International and European standards:

  • Identifying set of standards to use or to develop in order to cover the full spectrum of needs for eBusiness;
  • Proposing and applying governance tools at strategic and technical level (e.g. radar screen, interoperability framework, assessment process)
  • Developing a network of experts
  • Developing liaisons with all relevant standardization organization

Areas covered by D8 Product Support:

The domain is performed by the ASD Product Support Group and includes training on ASD-STE100.

Areas covered by D9 Environment:

Environmental considerations of all domains including Declaration Standards on chemical substances are covered by the Environment domain.

Areas covered by D10 Space

Space issues are addressed via the ASD EUROSPACE Standardization Panel.
