Overview
ISO 24671:2024 - Road vehicles - Qualification and certification of technical personnel dealing with natural gas vehicles (NGVs) - defines requirements for qualifying and certifying personnel who perform operations on natural gas vehicles and related fuelling systems. The standard targets the safety-driven competency levels required by different roles and specifies criteria for third‑party conformity assessment schemes. Certification at levels 3 and 4 is required (see ISO 23684 for the competence level definitions referenced in the standard).
Key topics and requirements
- Scope and responsibilities - Roles and duties for certification bodies, authorized qualification bodies, training providers, employers, applicants and examiners are defined.
- Qualification figures and levels - Classification of personnel roles and competency levels (Levels 1–4), with certification specifically required for Level 3 (fuelling station technical manager) and Level 4 (NGV technical manager).
- Eligibility and training - Requirements for eligibility, recognized training course formats, evidence of training, and minimum training duration (specified in the standard).
- Competence assessment - Combination of written theoretical exams, practical examinations and operational case assessments. Examinations include basic elements and role‑specific tests (e.g., fuelling station operations, NGV fuel-system tasks).
- Certification and recertification - Rules for certification administration, issuance, maintenance, renewal, suspension and withdrawal of certificates. The standard also sets out procedures for recertification and re‑examination.
- Record keeping and conformity assessment - Documentation requirements for certification bodies and employers; this document is oriented to third‑party schemes but can inform first‑ and second‑party arrangements.
Practical applications and who uses this standard
ISO 24671:2024 is used by organizations that need to ensure safe, standardized competence of NGV personnel:
- Certification bodies and conformity assessment organizations implementing third‑party NGV personnel certification schemes.
- Training providers designing NGV technician and manager courses to meet recognized competency criteria.
- NGV fleet operators, fuelling station owners, and maintenance workshops that employ or contract technicians for assembly, inspection, maintenance, repair and commissioning of NGVs and fuelling systems.
- Regulators and safety authorities adopting consistent competence requirements for NGV operations and infrastructure.
- Employers and HR teams using standardized certification to recruit, qualify and maintain a skilled NGV workforce.
Related standards
- ISO 23684 - Defines competence levels referenced by ISO 24671 for NGV personnel.
- ISO/IEC Directives are referenced for the development and maintenance approach of ISO documents.
