Emissions present and future in EU
Emissions present and future worldwide
The Refrigeration, Air Conditioning and Heat Pumps systems
containing fluorinated refrigerants in EU should have:
- Logbook
- Periodical inspections
- Installation, repair only by certified craftsmen
In Pills: To prevent refrigerant
emissions
Training and certification
Refrigerant to be sold by distributors
only to certified craftsmen
Refrigerant to be withdraw
only by certified craftsmen
Why creating
Training, Assessment, Certification
Certification is an important tool and a must to organize the labor market
according to the national qualification classification system
Through legislation, this will have the effect of:
• Reducing Refrigerant Emissions, GHG, ODS
• Increasing energy efficiency (reducing CO2)
Contractor-driven:
• More aggressive competition requires proof of higher quality and
certification
Customer-driven:
• Wholesalers, distributors, big customers … require environmentally
friendly and energy efficient products
• Protects the interests of customer through
providing services according to applicable standards
Certification of the personnel and
of the companies who handle air conditioning,
refrigeration and heat pumps equipment
Why creating
Training, Assessment, Certification (2) Certification will also play an important role for the sustainability of the
associations, as it could be an important income stream both through the
training and the certifications organized by the association.
The associations’ role in certification could be also:
•to work alongside the government to set the rules, certification schemes and
regulations
•a third party policing the correct implementation of the regulation
•certification body who guarantees the high standard of the certification
•certification body who issues the certification, renewing periodically
•the body who keeps the list, register and the records of certified technicians and
companies
Why creating
Training, Assessment, Certification (3)
It is recommended that only Certified Technicians holding a
certificate will be allowed to:
• install, maintain, repair, recover, dismantle RAC
systems containing refrigerants
• buy the refrigerant as a proved Certificate holder
NB. Informal Sector buys Refrigerant only if holding the
certification. This will stop the development of an informal
sector and in particular preventing the bad behavior
(accidents, emissions) which is most common in this
sector.
Certification
is the best practical method to
verify the competence of personnel
handling refrigerants and to ensure
the correct installation,
maintenance, repair and
dismantling of a refrigeration,
airconditioning and heat pump
systems.
Natural persons (personnel) carrying out certain tasks on certain types of equipment must be
certified or qualified.
Equipment
Stationary refrigeration, air conditioning, heat pump and fire protection equipment
Refrigerated trucks (above 3.5 t) and trailers
Air conditioning equipment in road vehicles
Tasks
a) Installation, servicing, maintenance
b) Repair
c) Decommissioning
d) Leakage checking
e) Recovery
Who needs to be certified?
(1 - Personnel)
*some countries worldwide offer the certification of companies. It is likely that developing countries could
use a different method to ensure the compliance of the requirements described below, for example
provided that the single service installer, as self-employed person, provides the compliance
Companies carrying out certain tasks on certain types of equipment for other parties must
be certified.
Equipment
Stationary refrigeration, air conditioning, heat pump and fire protection equipment
Tasks
Installation, servicing, maintenance
Repair
Decommissioning
Companies should fulfils the following requirements
(a) employment of personnel certified in accordance with Article 5, for the activities
requiring certification, in a sufficient number to cover the expected volume of activities;
(b) proof that the necessary tools and procedures are available to the personnel engaged
in activities for which certification is required.

Maximum 20-25 candidates per class dependent on number of assessors
Assessor/s should be independent and not involved in the training of the candidates
Multiple answers tests, 30 questions for 90 minutes duration
The same test among candidates with variation of questions to prevent predictability among candidates
Closed books, only specific technical tools such as calculator and pressure-temperature comparator
allowed
NO! mobile phones or cameras NO! copying or communication between candidates
YES! speaking to the assessor to ask explanation of the modalities and of the questions if not
understood; many candidates use different words and vocabulary to identify the same concept (eg. Valves)
Theoretical assessment: Pass mark above 60% correct answers
Laboratory is properly equipped for performing the practical test
Practical assessment: Pass if candidate proves competence in performing main RAC service technicians
activities without or with only small hesitations (remember candidates could be knowledgeable but be
nervous!):
• Thermodynamic parameters reading through gauges and
devices, temperature, pressure, subcooling, superheating
• Parameters interpretation, troubleshooting
• Perform a leak test
• Vacuum, charge, recovery with minimum emissions
• System Logbook reading, understanding and competition
• Brazing leak tight joints
Assessment: practical
organization issues
• Assessors and Trainers should hold a certificate
• Assessors should have multiple years of experience in the field
• Assessors should be comfortable in trainees’ evaluation
• Please see International Standards as ISO 17024 for more details
N.B in order to confirm the value and guarantee the sustainability of the
certification, standards must be kept high and therefore not everyone will
pass the exam!

issued at the end without a written, oral or practical
assessment which proves the ability of the service

Certification of technicians
in servicing sector how it runs (2)
Monitoring systems consists of putting in place several tools within the
National Certification Scheme:
• A register of certified personnel and companies publically available
online (recommended) or held by a national authority
• Only certified personnel and companies can purchase refrigerants and
refrigerant containing equipment
• Only certified personnel and companies can install, repair, maintain,
recover and dismantle RAC systems
• A register with the quantity of purchased and recovered refrigerants
(both at a certified personnel or company level and from at the
distributors) available to the authorities
• Refrigeration System Logbook containing relevant historical data of the
installation, maintenance and repair available for each system (a
threshold to avoid small systems, like domestic refrigeration and air
conditioning, could be evaluated)
The above allows the checking and monitoring of the whole sector,
whether the Service Technician and the company doing the job is
competent and prevents loopholes in the certification system
