Apply for exemption from the expert knowledge requirement in accordance with the Chemicals Ozone Layer Ordinance


In order to work on technical equipment that uses ozone-depleting substances, you must provide a certificate of competence.

To obtain a certificate of competence, you normally complete a training course followed by a competence test. The examination is offered both by state-approved private providers and by public bodies such as chambers of industry and commerce or chambers of trade.

In order to be admitted to the certificate of competence examination in certain categories, you must provide proof that you have completed technical or trade training. The IHK or HWK can exempt you from this requirement if you can prove that you have acquired the required technical skills elsewhere. You apply for exemption from the training requirement in writing to your IHK or HWK.

Exemption from the training requirement is a procedure that depends very much on the individual case, which is why you should find out about your options before applying to the IHK or HWK.

  • You meet the requirements for entry in the register of craftsmen
  • Alternatively, you can provide other proof that you are qualified to practise a trade
  • Possibly further documents, please ask the chamber to which you would like to apply for exemption for more details
  • Copy of the identity card
  • Proof of qualifying professional activities

Costs are incurred. The exact amount is determined by the chambers themselves.

  • The processing time is highly dependent on the individual case and cannot be specified in general terms

Contact the Chamber of Crafts or Chamber of Industry and Commerce.

  • Forms: Recognition form of the respective chamber
  • Online procedure possible: partially
  • Written form requirement: no
  • Personal appearance required: no

You apply in writing to a Chamber of Industry and Commerce (IHK) or Chamber of Crafts (HWK) for exemption from the requirement of a craft or technical apprenticeship. As the exemption depends very much on your personal requirements, you should seek advice from the chamber beforehand.

  • The chamber will check whether you meet the requirements even without a vocational qualification.
  • You will receive a certificate of exemption from craft or technical training.

You can now take the examination and, once you have passed it, carry out work on air conditioning systems in the relevant category.
