ISO 18841:2018

Overview

ISO 18841:2018 - Interpreting services: General requirements and recommendations specifies basic requirements for the provision of quality interpreting services and offers recommendations of good practice. It covers spoken and signed language interpreting, defining terms, modes (consecutive, simultaneous, chuchotage), and core principles to facilitate faithful, non‑written communication across languages. The standard is intended as a general framework that can be used alongside specialization standards (e.g., legal interpreting).

Key topics and technical requirements

• Terminology and definitions: Clear definitions for interpreter roles, client, end user, source/target language, and ‘A/B/C’ language classifications help standardize language-service contracts and expectations.
• Modes of interpreting: Requirements and recommendations for consecutive interpreting, simultaneous interpreting, whispered interpreting (chuchotage), sight translation and distance/remote interpreting.
• Assignment lifecycle: Requirements for request and offer, accepting assignments, working conditions during assignments, and responsibilities after assignments.
• Protocols and codes of conduct: Guidance on professional behaviour, ethical obligations and interpreting protocols to ensure impartiality, confidentiality and accuracy.
• Qualifications and competences: Framework for interpreter qualifications and competence areas including linguistic, intercultural, interpersonal, technical, domain knowledge and continuous professional development.
• Service context and specializations: Non‑exhaustive lists and definitions for settings such as conference, community, legal and healthcare interpreting, with references to specialized standards where applicable.
• Annexes: Practical material such as parties’ responsibilities (normative), settings and specializations (informative), and interpreters’ self‑care (informative).

Applications and who uses it

ISO 18841:2018 is practical for:

• Interpreting service providers (ISPs) and freelance interpreters - to structure service delivery, contracts, and professional development.
• Language service buyers (public bodies, healthcare providers, courts, NGOs, conference organizers) - to define procurement criteria and quality expectations for interpreting services.
• Training and certification bodies - to design curricula and competency frameworks reflecting industry best practice.
• Quality and compliance teams - to incorporate interpreting requirements into organizational policies, codes of conduct and service-level agreements. Use cases include drafting interpreting contracts, setting workplace protocols, designing remote interpreting workflows, and aligning interpreter selection to competency profiles.
