    • B8. VAT number, what is it?

      A common VAT system is compulsory for member states of the European Union.
      The EU VAT system is imposed by a series of European Union directives, the most important of which is the Sixth VAT Directive (Directive 77/388/EC).
      Nevertheless, some member states have negotiated VAT exemption or variable rates for regions or territories. The Canary Islands, Ceuta and Melilla (Spain), Gibraltar (UK) and Åland Islands (Finland) are outside the scope of the EU system of VAT, while the Autonomous regions of Portugal (Azores and Madeira) are allowed to levy rates lower than Mainland Portugal.

      Under the EU system of VAT, where a person carrying on an economic activity supplies goods and services to another person, and the value of the supplies passes financial limits, the supplier is required to register with the local taxation authorities and
      charge its customers, and account to the local taxation authority for, VAT (although the price may be inclusive of VAT, so VAT is included as part of the agreed price, or exclusive of VAT, so VAT is payable in addition to the agreed price).

      VAT that is charged by a business and paid by its customers is known as output VAT (that is, VAT on its output supplies). VAT that is paid by a business to other
      businesses on the supplies that it receives is known as input VAT (that is, VAT
      on its input supplies). A business is generally able to recover input VAT to the
      extent that the input VAT is attributable to (that is, used to make) its taxable
      outputs. Input VAT is recovered by setting it against the output VAT for which the
      business is required to account to the government, or, if there is an excess,
      by claiming a repayment from the government.

      Different rates of VAT apply in different EU member states.
      The minimum standard rate of VAT throughout the EU is 15%, although reduced rates of VAT,
      as low as 5%, are applied in various states on various sorts of supply (for example,
      domestic fuel and power in the UK). The maximum rate in the EU is 25%.

  • C. Preparing for IRIS

  • D. IRIS in general

    • D1. Which companies can apply for an IRIS Certificate?

      IRIS is only applicable to Rolling Stock, Signalling and Infrastructure companies having manufacturing and/or design and/or maintenance activities.

    • D2. How is the independency of the IRIS scheme guaranteed?

      The IRIS scheme is under UNIFE's supervision and control. The IRIS Management Centre is responsible for the respect of the rules.  For instance, the evaluation process is conducted by independent auditors, coming from IRIS approved certification bodies.

    • D3. Are there any legal concerns (closed market)?

      All untitrust issues and market competition issues have been considered during the development phase of the IRIS initiative.

    • D4. Will the TSIs (Technical Specification for Interoperability) consider/refer to IRIS in their requirements?

      The quality Modules of Chapter 6 of each TSI require the acceptance by the NoBos of all certified quality management systems.

    • D5. What is the difference between Outsourcing and transfer of processes?

      Within the ISO 9001 framework, outsourcing can be understood as purchasing,
      sub-contracting, transfer, procurement,… each having different ways
      of implementation within an organization.

      Within the ISO/TS 22163, it is preferred to use terms which are
      clearly linked to the rail understanding. 

      For this reason, TRANSFER (as defined in ISO TS 22163, Subclause 3.1.42)
      is meant for processes where the ownership
      (responsibility) is partly or completely handed over to another internal or external

      A typical example is transfer of the painting process (temporarily
      of definitely):

      The aim is to keep all process parameters in order to ensure the
      same results (products, times, tools,…), only the manpower changes
      and need to be trained. As a difference for a purchased painting process,
      the supplier would have the choice of the painting products, tools, ….
      but shall anyhow achieve the same requirements in terms of gloss,
      thickness,….. Therefore he needs to validate the new parameters of
      his process to ensure the capability of his new process compared to
      the previous one done in another location. 

    • D6. What are the rules about multi-site certification within the IRIS scheme? 

      The IRIS certification process follows a single site certification approach.
      A multi site certification approach (one certificate for several sites, no systematic annual audits,...) does not apply for the IRIS scheme. 
      There are possibilities for a site extension and remote location. Further information can be found in the IRIS Certification® conformity assessment:2020 in chapter 5.8 SUPPORTING ACTIVITIES.

    • D7. How can I obtain the IRIS assessment sheet?

      The IRIS assessment sheet is available directly inside the IRIS Audit-Tool and can only be exported by PDF due to copyright issues. To purchase the IRIS Audit-Tool, please click the following link.

    • D8. What are IRIS activities?

      IRIS certified companies have activities in at least one of the following areas:
      - Design and development
      - Manufacturing
      - Maintenance

      It is also possible to have two or all three of the above mentioned activities.

      This has no relation towards the type of products the IRIS certified company produces.

    • D9. What are IRIS scopes for certification?

      IRIS scopes for certification are related to the products the company wants to be certified for.
      There are 20 scopes, which are listed in appendix 1: IRIS CERTIFICATION® SCOPE OF CERTIFICATION in the IRIS conformaty assessment:2020 publication.
      It's possible to be certified for several product scopes.  

  • E. IRIS and operators 

    • E1. How is IRIS managed as a global scheme?

      IRQB – the International Rail Quality Board, is a global consortium that brings together leading companies in rail operations, system integration and equipment manufacturing.


      Established in September 2018, the IRQB aims to foster a global culture of quality across the whole rail sector, notably by promoting the use of the IRIS Certification® system worldwide to ensure high product quality.


      IRQB believes that better Quality will ultimately improve daily mobility on rail, therefore IRIS Certification® must be the seal of all involved stakeholders.


    • E2. Does IRIS include Operators Requirements?

      Operator representatives have been involved in the IRQB Working Groups where their requirements have been identified and included in the IRIS Rev. 03 and related documents.

    • E3. Where can I find help?

      The IRIS guidelines are supporting documents helping companies to comply with the rules specified in the IRIS Certification® rev. 03. Each guideline provides useful information for rail sector companies related to specific working areas of the organization. These guidelines are prepared by dedicated experts of the worldwide IRQB members from all around the rail sector.

      We invite you to consult this page regularly to discover new guidelines. Please note that all IRIS Guidelines will be published exclusively on this page.

  • F. IRIS and auditors / certification bodies
