TS EN ISO 21043-1

TS EN ISO 21043-1 is a vocabulary standard for forensic sciences, bringing together the terms and definitions used across the field. Its purpose is to support consistent language throughout the forensic process, from scene work and evidence handling to interpretation and presentation in court. In practical terms, it provides a shared terminological foundation for a discipline that depends on precise communication between scientific and legal actors.

A common language for the forensic process

Forensic science is not a single activity but a sequence of connected tasks, including scene examination, sample collection, laboratory analysis, evaluation of findings, and communication of results to judicial decision-makers. By defining the terms used in these different components, this standard helps reduce ambiguity and improves the clarity of professional communication. As general technical context, a controlled vocabulary is especially valuable where the same word can carry different meanings in science, investigation, and legal proceedings.

What this document covers

• Terms used for the different components of the forensic process are defined.
• The scope follows the process from scene to courtroom.
• This is a terminology document; it does not specify a test method or laboratory procedure.
• It supports consistent use of forensic concepts across disciplines.

Vocabulary standards do more than list words: they set boundaries around concepts. In forensic sciences, that matters because evidence, findings, interpretation, report, and expert opinion may sound related but play different roles in the workflow. This standard’s conceptual framework helps align those distinctions and makes interdisciplinary forensic communication more reliable.
