ISO 18436-1:2021

Overview

ISO 18436-1:2021 is an international standard providing sector-specific requirements for certification bodies and the certification process related to personnel involved in condition monitoring and diagnostics of machine systems. This third edition, published by ISO, defines the framework for organizations conducting conformity assessments of personnel who monitor machinery conditions, identify faults, and recommend corrective actions. The standard complements the general requirements established in ISO/IEC 17000 and ISO/IEC 17024, focusing specifically on certification schemes for professionals working within non-intrusive machine condition monitoring technologies.

Key Topics

• Certification Body Requirements
  Certification bodies must comply with ISO/IEC 17024 and additional sector-specific rules under ISO 18436-1. They are responsible for ensuring certification schemes reflect the competencies needed to assess condition monitoring personnel effectively.

• Examination and Assessment Process
  Examinations must be conducted under controlled conditions at approved centers. The standard details rules for closed-book exams, use of drafting tools, re-examination policies, and ethical conduct during assessment. Examiners need to hold certifications at a level equal to or higher than the candidates being tested.

• Mature Candidate Entry
  Mature candidates with substantial training and experience may gain direct entry to higher certification categories, bypassing lower levels if they meet stipulated requirements, thus offering flexibility in certification pathways.

• Certification Validity and Recertification
  Certification validity extends up to five years. Renewal requires documented evidence of ongoing professional activity and adherence to ethical standards. Revocation or invalidation can happen due to ethical breaches or inability to perform duties.

• Code of Ethics
  Certified personnel are expected to demonstrate integrity, professionalism, and competence in all condition monitoring activities, ensuring trustworthiness of the certification scheme and quality of diagnostic outcomes.

Applications

ISO 18436-1:2021 is essential for organizations that:

• Operate third-party certification schemes for machine condition monitoring professionals.
• Manage compliance within maintenance, asset management, and reliability programs by certifying qualified diagnostic personnel.
• Provide training, examination, and certification services to ensure that condition monitoring experts meet industry competency standards.
• Develop policy frameworks for certification processes in sectors utilizing vibration analysis, infrared thermography, lubricant analysis, acoustic and ultrasonic analysis, and electric signature analysis.

By adhering to this standard, certification bodies enhance the reliability and consistency of personnel assessments, contributing to improved machinery maintenance strategies and minimized equipment downtime.
