F-Gas Certification - City and Guilds 2079 Cat I & II - Assessment

This comprehensive package comprises three components;

• Sit the online GOLA test of theoretical knowledge.
• Undertake the practical assessment.

The GOLA test of theoretical knowledge and the practical assessment will take no more than a half-day so by choosing our nearest branch office to you will mean no more than one day away from your workplace.

The GOLA test and practical assessment will test your knowledge and competence in a number of areas, including;

City & Guilds 2079 – F-Gas Certification

What is involved in the practical assessment?
For Categories 1 and 2 the candidate must provide evidence of ability to:

• Identify states of refrigerant i.e saturated, superheated, sub-cooled
• Identify common refrigerants
• Carry out safe brazing techniques
• Charge refrigerants
• Carry out leak testing
• Pressure test
• Evacuate systems
• Select appropriate PPE
• Maintain appropriate records

What is involved in the theoretical assessment?

· Units of temperature, pressure, mass density and enthalpy

· Basic theory/thermodynamics including basic vapour compression cycle, states of refrigerant, refrigerant blends and operating conditions

· Monitoring system performance for indications that leakage has occurred

· Knowledge of climate change and the Kyoto Protocol

· Equipment records/commissioning data requirements

· Identification potential leakage points of refrigeration/air conditioning and heat pump equipment

· Handling, storage, transportation and disposal of contaminated refrigerant and oil

· Functions of and reports on the state/condition of expansion valves and capillary tube restrictors

· HCFC gases and potential for Ozone depletion

· Hazards associated with release of refrigerant gases
