What does the standard ISO/TS 22163 cover?

The ISO/TS 22163 standard defines the requirements for a quality management system (Business Management System) of a company that delivers products to the railway industry. These requirements include, but are not limited to:

  • The organisation has established a suitable management system which includes mechanisms for risk & chance identification, self-assessment, preventive and corrective action, continuous improvement of performance as well as knowledge management, RAMS/LCC, project management and supply chain management. For this purpose, the organisation must, as a minimum requirement, furnish proof of the processes, procedures, records and key performance indicators - in particular the five compulsory processes to be assessed by process performance indicators, which in turn are based on process analyzes (so called turtles) - required by this international standard.
  • The organisation analyses and considers the quality requirements of its customers and authorities as well as the requirements of the applicable standard.
  • The certified organisation defines the required characteristics of the products and services offered and the underlying processes, and ensures regular surveillance to meet the quality requirements of customers.  
  • What does “certification” and/or the issue of a certification mark for ISO/TS 22163 by TÜV SÜD Management Service GmbH mean?
    • The customer has submitted to voluntary assessment (audit) according to defined criteria (certification standard).
    • A certificate and/or the authorisation to use a certification mark is only issued if the assessment (audit) does not reveal any nonconformities with the requirements of the certification standard.
    • The certificates and/or certification marks are valid for a restricted period of time. Interested parties can check the validity of individual certificates in the certificate database of TÜV SÜD Management Service GmbH or the ISO/TS 22163 database provided by the standard owner.
    • To maintain certificate validity, the certificate holder must annually complete an announced audit with a positive result. Exceptions exist for so called remote locations without responsibility for design.
    • Unannounced audits are possible in specific cases.
  • How do we audit?

    Independent and qualified experts (auditors) apply the following auditing techniques:

    • Document review (Readiness Review)
      Evaluation of the organisation’s requirements and/or documentation to ensure the systematic control of all processes relevant for quality management and required by this international standard.

    • On-site-audit
      Verification, in the form of interviews and on-site inspection at the customer's premises, that the above requirements are effectively implemented in practice. Random on-site checks of processes based on records, such as available measurement results, minutes of meetings, training and qualification records, complaints management and records related to defined objectives and the resulting improvement projects.
  • What is beyond the scope of certification according to ISO/TS 22163?
    • Certification according to ISO/TS 22163 does not constitute product certification. Certification thus does not provide any direct statements on the quality of a product or service of the certified customer. Certification according to ISO/TS 22163 does not mean that the company manufactures products or provides services of higher quality.
    • Certification according to ISO/TS 22163 does not ensure in each specific case that a product or service complies with customer requirements, even though this is one of the key objectives of the quality management system.
