The aim is to assist industrial employers and maintenance teams in correctly interpreting the ISO 18436 series.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The technical application of techniques such as vibration analysis, fat analysis, and thermography is covered in the relevant service pages on the AES website; this page does not repeat that technical content, but only describes the competency scope of personnel performing these tasks.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li>Focus: Competence and certification framework for situation monitoring personnel.<\/li>\n\n\n<li>Excluded: Technical application of vibration\/thermography\/fat analysis (see relevant service pages)<\/li>\n\n\n<li>Target audience: predictive maintenance teams, facility\/maintenance managers, employers selecting outsourced service providers.<\/li>\n\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Why the Outcome of Situation Monitoring Depends on Staff Competence<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Data collected during condition monitoring alone does not produce a decision; who interprets the data and with what expertise determines the outcome. The same vibration spectrum, which may appear normal to an inexperienced eye, could be read as an early bearing defect by a skilled analyst.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Misdiagnosis has a twofold cost. Reporting a non-existent fault leads to unnecessary downtime, disassembly and reassembly, and production loss; conversely, overlooking a genuine defect can result in unexpected failure, collateral damage, and safety risks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, the ISO 18436 series places the knowledge, experience, and test-verified competence of personnel at the center of the standard, before any device or method.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li>False positive diagnosis: unnecessary downtime, unnecessary maintenance costs, lost production.<\/li>\n\n\n<li>False negative diagnosis: missed fault, secondary damage, safety risk.<\/li>\n\n\n<li>The value of a measurement is directly proportional to the verified competence of the personnel interpreting it.<\/li>\n\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Structure of the ISO 18436 Series<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">ISO 18436, \u201cCondition monitoring and diagnostics of machinery \u2013 Requirements for qualification and evaluation\/certification of personnel\u201d, is a series of multiple sections. One section defines the general framework of the program, while the other sections define the specific requirements for each technology.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The following list provides a summary of the series&#039; general architecture for informational purposes; however, the current editions and contents of the chapters may be revised over time, so the most accurate requirements should be based on the current standard text.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li>ISO 18436-1: Industry requirements for certification\/assessment bodies and the certification process.<\/li>\n\n\n<li>ISO 18436-2: Vibration condition monitoring and diagnostics personnel.<\/li>\n\n\n<li>ISO 18436-3: Requirements for educational institutions (training providers)<\/li>\n\n\n<li>ISO 18436-4: Field and laboratory lubricant\/oil analysis personnel (lubricant analysis techniques)<\/li>\n\n\n<li>ISO 18436-5: Lubricant field analysis (field oil analysis technician)<\/li>\n\n\n<li>ISO 18436-6: Acoustic emissions<\/li>\n\n\n<li>ISO 18436-7: Thermography (infrared thermography)<\/li>\n\n\n<li>ISO 18436-8: Ultrasonic (ultrasound) methods<\/li>\n\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Category and Level Structure<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Technical departments categorize personnel according to increasing authority and responsibility. Generally, Category I represents the basic level, while higher categories indicate increased theoretical knowledge, independent interpretation skills, and team leadership responsibility. For example, the vibration department defines a four-category structure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For each category, a minimum level of education, a minimum period of experience in the relevant field, and a successful examination are typically required. Subcategories encompass predefined tasks under supervision; overarching categories cover independent diagnostics, procedure development, and more senior technical responsibilities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Since exact experience periods, examination requirements, and recertification intervals vary depending on the relevant section and edition, specific hours\/years figures are not bindingly given on this page; current values should be confirmed with the applicable standard and certification body scheme.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li>Category I: basic level, mostly predefined tasks under supervision\/monitoring.<\/li>\n\n\n<li>Category II: competence in independent measurement and data interpretation.<\/li>\n\n\n<li>Category III\/IV: advanced diagnostics, procedure development, in-team technical leadership<\/li>\n\n\n<li>The three things required together in every category: education + minimum experience + exam.<\/li>\n\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Relationship with ISO\/IEC 17024<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">According to ISO 18436, personnel certification is not based on an independent framework, but on TS EN ISO\/IEC 17024, the general standard for organizations that certify personnel. ISO 18436-1 defines requirements specific to the condition monitoring sector in addition to these general requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This two-tiered structure aims to ensure the impartiality of certification, the reliability of examinations, and the repeatability of decisions. In practice, the value of a personnel certificate is directly related to the accreditation scope and impartiality of the issuing organization.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When evaluating the validity of a personnel certificate, it should be checked whether the issuing organization is accredited according to ISO\/IEC 17024 and whether the scope of accreditation includes the relevant ISO 18436 technique.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li>ISO\/IEC 17024: General\/basic standard for organizations certifying personnel.<\/li>\n\n\n<li>Sector-specific requirements added to ISO 18436-1: 17024.<\/li>\n\n\n<li>The strength of the document depends on the scope of accreditation and impartiality of the issuing organization.<\/li>\n\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Who is it for and what is the employer&#039;s responsibility?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Competence under ISO 18436 is relevant for in-house predictive maintenance team members, vibration\/thermography\/oil analysis specialists, and outsourced\/consultant personnel providing this service. The competency level of everyone performing and interpreting the measurements determines the reliability of the resulting report.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The employer&#039;s responsibility is not limited to simply providing the correct equipment. It is also the employer&#039;s responsibility to assign certified personnel in the appropriate risk category for the job, to verify the qualifications and certifications of outsourced personnel, and to monitor the currency of these certifications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When evaluating an external service provider, the following should be considered: which ISO 18436 technique it is certified under, which category, which organization it is certified by, and the validity period of the certification.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li>Scope: internal predictive maintenance team and external service provider personnel.<\/li>\n\n\n<li>Employer: assigning certified personnel in a category appropriate to the risk level of the job.<\/li>\n\n\n<li>Employer: technical, category, certifying body and validity verification in external service.<\/li>\n\n\n<li>Employer: monitoring the currency of employee documents.<\/li>\n\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">AES&#039;s Location and Scope of Accreditation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">AES (aesinn.com) is a T\u00dcRKAK-accredited Type A electrical inspection organization.

It focuses less on how techniques such as vibration, oil analysis, and thermography are applied, and more on the knowledge, experience, and examination requirements that personnel performing these tasks must meet. This is an informational summary; precise requirements should be confirmed from the applicable standard text.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What do ISO 18436 categories (I-II-III\/IV) mean?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Categories represent the increasing authority and responsibility of personnel. Category I typically encompasses core tasks under supervision; higher categories cover independent data interpretation, advanced diagnostics, procedure development, and in-team technical leadership. For example, the vibration department defines a four-category structure. Training, minimum experience, and examinations are required in each category; exact durations vary by department and pressure.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is the relationship between ISO 18436 and ISO\/IEC 17024?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Personnel certification under ISO 18436 is based on TS EN ISO\/IEC 17024, the general standard for organizations certifying personnel. ISO 18436-1 introduces requirements specific to the condition monitoring sector in addition to these general requirements. When evaluating the validity of a personnel certificate, it should be checked whether the issuing organization is accredited according to ISO\/IEC 17024 and whether its scope includes the relevant technology.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does AES issue personnel certificates under ISO 18436?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No. AES is not a status monitoring personnel certification body and does not issue personnel certificates\/documents under ISO 18436. Such certification is carried out by T\u00dcRKAK accredited TS EN ISO\/IEC 17024 organizations. This page is for informational purposes only and is within the framework of authorized engineer technical assessment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do I, as an employer, verify the qualifications of my staff?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In evaluating external service providers or internal teams, it should be checked which ISO 18436 technique (vibration, oil analysis, thermography, etc.) the personnel are certified in, in which category, by which organization, and the validity period of the certification. It is the employer&#039;s responsibility to oversee the assignment of personnel with up-to-date certifications in a category appropriate to the risk level of the job.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is the technical application of vibration analysis described on this page?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No. The technical application of vibration analysis and other condition monitoring methods is covered in the relevant service pages on the AES website.
