TSE ISO/IEC GUIDE 73

TSE ISO/IEC GUIDE 73: TSE ISO/IEC Guide 73 is a guide for the way risk management terms should be defined and used in standards. Its purpose is to bring order to the vocabulary of risk management so that standards writers use key terms consistently and avoid shifting meanings from one document to another. The focus is not on prescribing a risk process itself, but on the language used to describe that process.

Where risk terminology fits in standardization

Risk management is a structured approach to dealing with the effect of uncertainty on objectives. In practice, concepts such as hazard, event, likelihood, consequence, control and risk appetite are closely related and can easily be confused if they are not defined carefully. In general technical context, a shared vocabulary supports clearer drafting, better interpretation and more reliable communication across standards, organizations and sectors.

How this guide is used in practice

• It provides generic definitions intended for use in standards.
• It helps keep related risk terms conceptually distinct.
• It supports consistency across different fields that use risk language.
• It guides standards authors toward clearer and more uniform terminology.

This TSE publication is based on ISO/IEC Guide 73:2002 and is now withdrawn. As such, it remains useful as a historical and terminological reference, especially for understanding how risk management vocabulary has been organized for standardization purposes.
