ASD-STE100: International Standard for Simplified Technical English

LinkASD Simplified Technical English Maintenance Group (STEMG)Resource

The official website of the ASD Simplified Technical English Maintenance Group (STEMG) provides information on ASD-STE100. The controlled natural language standardises technical documentation and is available as Issue 9, released in January 2025.

Key points

  1. ASD-STE100 is a controlled natural language and an international standard for technical documentation owned by ASD (Brussels).
  2. Originally developed in the late 1970s, the initial guide appeared in 1986, became an international specification in 2005, and became an international standard in 2025.
  3. Issue 9 was released on 15 January 2025 and is available upon request free of charge.
  4. Use cases extend beyond aerospace and defence to computer science, IT (such as human-machine interfaces), commercial industry, and academia.

Why it matters

Unambiguous technical writing reduces operational errors and translation costs. Standardised linguistic rules support non-native speakers and improve clarity across complex technical documentation and interface designs.

Analysis

The evolution of ASD-STE100 into an official international standard in 2025 highlights the increasing demand for structured, controlled languages. By constraining grammar and vocabulary, it mitigates misinterpretation in safety-critical sectors and human-computer interactions.
