Frequently Asked Questions

Why should I participate in the SF6 certification training?

What are the legal regulations?

New (EC) 517/2014 F gas regulation
This regulation has been in force since 01st January 2015 and replaces the 842/2006 directive on fluor gas. It is valid for the following fluorinated greenhouse gases:

  • Partly fluorinating hydrocarbons (HFKW)
  • Perfluorocarbons (FKW)
  • Sulphur hexafluoride (SF6)

The aim of this regulation is to reduce or avoid emissions of fluorinated greenhouse gases. In accordance with this regulation only certified personnel is allowed to carry out the SF6 gas handling in the 28 EU member states. This regulation stipulates the required training and certification of personnel as well as reporting obligations.

Certification in accordance with the (EU) 517/2014 F-gas Regulation and (EU) 2015/2066 regulation
Article 10 of the new Regulation (EU) no. 517/2014 refers to existing requirements and states that existing certificates and training attestations issued in accordance with regulation no. 842/2006 shall remain valid, according to the conditions under which they were originally issued. The minimum requirements for the certification of personnel are laid down in regulation (EU) 305/2008.

Personnel carrying out gas handling works (such as filling, measuring and reclaiming of SF6) shall still be certified.
