Glossary

Attestation – Proof of qualification (the term attestation is used in the F-Gas Regulation
for qualifications related to mobile air-conditioning).

Automatic leak detection system – Calibrated mechanical, electrical or electronic device for detecting
leakage of F-Gases which, on detection, alerts the operator or a service company of any leakage.

Central pack systems – A type of refrigeration system, mainly used in large supermarkets. A
number of retail display cases is connected to a remotely located set of refrigeration compressors (the “pack”) and an externally located condenser system.

Certificated technicians – Individuals that have undertaken appropriate training so they are qualified
to undertake work with F gases on specified equipment.

Chlorofluorocarbon (CFC) – A family of chemicals consisting of chlorine, fluorine and carbon. CFCs
were historically used in various applications such as refrigeration, foam blowing, and aerosols. Now completely banned under the EU Ozone Regulation. CFCs have very high global warming potentials.

CO2 equivalent (CO2e) – A quantity of greenhouse gas, expressed as the product of the weight of
the greenhouse gas in metric tonnes and the global warming potential of the gas.

Commercial use – Used for the storage, display or dispensing of products, for sale to end
users, in retail and food services.

Company Certificate – Certification of an undertaking that requires the company to demonstrate
that they employ sufficient certificated technicians and that they use equipment and operating procedures that helps prevent F-Gas emissions. Company Certificates are required by all undertakings carrying out installation or servicing of RACHP or FPS systems on behalf of 3rd parties. A Company Certificate is required by sole traders as well as larger companies.

Competent authority – Body that can enforce the F-Gas Regulation. In the UK the competent authority is the Environment Agency.

Condensing units – A type of refrigeration system, mainly used in small commercial applications. The evaporator serving a cooling load (e.g. a retail display or a walk-in cold room) is connected to a remotely located condensing unit, which consists of a compressor and condenser.

Decommissioning – Means the final shut-down and removal from operation or usage of a product or piece of equipment containing fluorinated greenhouse gases.

Declaration of conformity – A legally verifiable document provided by a manufacturer, or his authorised representative. It shows that a product meets all the necessary requirements laid down in the applicable EU Directives. It can be used to indicate that imports of equipment pre-charged with HFCs have used HFCs sourced from the EU quota system.

Destruction – Means the process of permanently transforming or decomposing all or most of a fluorinated greenhouse gas into one or more stable substances that are not fluorinated greenhouse gases.

Extruded polystyrene foam (XPS) – A form of closed cell insulating foam. Feedstock Any F-Gas, or other substance listed in Annex II of the EU F-Gas Regulation, that undergoes chemical transformation in a process in which it is entirely converted from its original composition and its emissions are insignificant.

Fluorinated greenhouse gases (FGases) The greenhouse gases listed in Annex I of the F-Gas Regulation, or mixtures containing any of those substances. The gases include HFCs, PFCs and SF6.

Gas insulated switchgear (GIS) – Equipment that uses SF6 as an insulating gas in high voltage electrical applications.

Global warming potential (GWP) – The climatic warming potential of a greenhouse gas relative to that of
carbon dioxide, calculated in terms of the 100-year warming potential of one kilogram of a greenhouse gas relative to one kilogram of CO2. The GWPs of relevant gases are listed in Annexes I, II and IV of the F-Gas Regulation. The GWP of mixtures is calculated in accordance with Annex IV.

Greenhouse gas (GHG) – A type of gas that makes a contribution to global warming if emitted to the
atmosphere. Most fluorinated gases including CFCs, HFCs, PFC and SF6 are very powerful GHGs.

Hydrofluorocarbons (HFCs) – A family of chemicals consisting of hydrogen, fluorine and carbon. HCFCs are ozone depleting substances and have been phased out in the EU. HFCs have very high global warming potentials.

Hydrofluoro-olefins (HFOs) – HFOs consist of the same chemical elements as HFCs (i.e. hydrogen,
fluorine and carbon). HFOs are unsaturated molecules (i.e. they have a double bond between 2 carbon atoms). This makes them less chemically stable than HFCs, resulting in very low GWPs. HFOs are being developed as possible alternatives to HFCs.

Incumbent quota holder – A holder of quota to sell HFCs in the EU market that placed HFCs on the market in the baseline period, 2009 to 2012.

Letter of Assurance – A letter used during customer screening to provide certification details to
a seller of bulk F-Gases.

Lower flammability limit (LFL) – LFL is the minimum concentration of a gas or vapour that is capable of
propagating a flame within a homogeneous mixture of that gas or vapour and air.

Maintenance or servicing – Means all activities that entail breaking into the circuits containing or
designed to contain F-Gases, in particular supplying the system with fluorinated greenhouse gases, removing one or more pieces of circuit or equipment, reassembling two or more pieces of circuit or equipment, as well as repairing leaks.

Metered dose inhaler (MDI) – Medical aerosol used to dispense certain drugs (e.g. inhalers for asthma
treatment).

Upper Flammability Limit (UFL) – UFL is the maximum concentration of a gas or vapour that is capable of propagating a flame within a homogeneous mixture of that gas or vapour and air.

Virgin refrigerant – Means a refrigerant which has not previously been used.

The SRAC industry and the world as a whole, now understand that fluorinated gases have a potentially devastating global warming effect when released into the atmosphere.

F Gas regulations have been implemented in order to contain, prevent and thereby reduce emissions of fluorinated greenhouse gases.

On 2nd April 2008, the Commission Regulation 303/2008 set out the requirements for a company certification scheme.

This scheme is specifically for businesses working with F Gas refrigeration, air-conditioning and heat pump equipment containing or designed to contain fluorinated greenhouse gases.

These F Gas Certification requirements are in accordance with Article 5.1 of EC Regulations 842/2006 on certain fluorinated greenhouse gases (the EC F Gas Regulation).
