Audi Q5: Laws and Regulations
General Information
Note
The laws and regulations listed below are applicable in
Germany. Different or additional laws and regulations may apply
in other countries.
The effects of climate change can be seen worldwide.
Protecting the climate is one of the most important
responsibilities. However, this responsibility presents enormous
challenges to all involved.
The Kyoto Protocol outlines worldwide goals regarding
climate protection, among other things. In addition to target
reductions of carbon dioxide, this protocol also outlines target
reductions for fluorinated greenhouse gases such as refrigerant
R134a due to their high potential of contributing to the
greenhouse effect.
Numerous laws have been created for the automotive industry,
for example at the European level. For example, chemical-climate
protection regulations were put into effect on August 1, 2008 in
Germany in order to define the European legislation in more
detail.
- Provision (EU) number 1005/2009
- Provision (EU) number 2037/2000
- Provision (EU) number 842/2006 (from 01/01/2015: EU no.
517/2014)
- Provision (EU) number 706/2007
- Provision (EU) number 307/2008
- Guideline 2006/40/EU
- Chemical-climate protection provision, recycling management
and disposal regulations (for Germany).
Maintenance and Repair Work on the A/C System Refrigerant
Circuit
All individuals performing maintenance and repair work on
vehicle A/C systems must have completed a training program and
be competent in the work required. Other regulations may apply
in addition to those of the European Union.
The Following General Points Apply:
Operation, repair, decommissioning, take-back obligation
- When operating, repairing and decommissioning items that
contain refrigerant, allowing the refrigerant to vent into the
air is prohibited.
- Keep records on the quantities used during operation and
maintenance so they can be presented to the authorities upon
request. A record sheet no longer needs to be kept in the EU due
to a provision by the European Parliament in 2005. Other
provisions may apply in countries that are not members of the EU.
- Distributors of the substances and preparations discussed
above are obligated to accept these items back after use or to
ensure they are accepted by a third party of their choosing.
- Maintenance and decommissioning of items containing
refrigerant that are named in the legislation Substances and
preparations named in this legislation may only be accepted by
those with the necessary expertise and technical equipment.
Criminal offenses and infringements of the law
- Infringement of the law in regard to the laws mentioned
above. Willfully or negligently venting refrigerant into the air
when operating, repairing or decommissioning items That contain
refrigerant constitutes a violation of the laws and legislation
described above.
Observe the different technical regulations for handling and
filling compressed gases (for example TRGS 400, TRGS 402, TRGS
407 TRGS 510 TRGS 725/TRBS3145).
Note
The TRGS (technical regulations for compressed gases) are
listed (concerning vehicle manufacturers and workshops) below.
- TRGS 400 (hazard assessment for activities with hazardous
substances)
- TRGS 402 (determining and evaluating the danger of
activities with hazardous substances: exposure)
- TRGS 407 (activities with gasses - hazard assessment)
- TRGS 510 (storage of hazardous substances in transportable
tanks)
- TRBS 3145/TRGS 725 (transportable tanks - filling, keeping
ready, internal transportation, emptying)
Note
- The technical regulations for compressed gases (TRG),
technical regulations for hazardous substances (TRGS) and the
technical regulations for operational safety (TRBS) provide the
laws and regulations, the safety precautions and work hygiene as
well as the protected industrial science knowledge for the
provision and use of work equipment such as the system use
subject to special supervision or for the activities with
hazardous substances.
- The provided technical regulations apply to Germany, in
other countries specifications and rules may apply.
Observe the different technical regulations for handling and
filling compressed gases (for example TRGS 400, TRGS 402, TRGS
407 TRGS 510 TRGS 725/TRBS3145).
- General regulations for charging systems
- Definition of terms and explanatory notes
- Build and operation of charging systems
Charging systems
- Does not apply to vehicle manufacturers or workshops.
- Charging systems are systems for filling mobile
compressed-gas containers. The charging system includes the
premises and facilities concerned.
- Charging systems requiring a permit are ones used to
transfer compressed gases to mobile compressed-gas containers
for supplying to third parties.
- Charging systems not requiring a permit are ones used for
transferring compressed gases to mobile compressed-gas
containers for internal use only.
Employees and employee instruction
- Employees are to be given instruction on the following
topics before beginning work and at regular, appropriate
intervals, however at least once a year
- Hazards specifically associated with handling compressed
gases
- The safety regulations, especially the present TRGS and
TRBS.
- Procedures in the event of malfunction, damage and accidents
- The use of fire-extinguishing and protective equipment
- Operation and maintenance of the charging system on the
basis of the instructions for use
Charging systems are only to be operated and maintained by
personnel.
- Aged 18 and above
- Possessing the necessary technical knowledge.
- Who can be relied on to work diligently.
Note
Supervised work may also be performed by personnel that do
not meet the requirements stipulated.
Filling of pressure containers (separate technical
regulations apply to containers from other countries and their
charging, that are not mentioned here).
- A compressed-gas container is only to be filled with the
compressed gas declared on it and the quantity must comply with
the stipulated pressure, weight or volume data. Refer to
pressure container regulations.
- In the case of containers approved for use with several
types of compressed gas, the compressed gas with which it is to
be filled and - if the compressed gas has a critical temperature
greater than or equal to -10 ºC (-14 ºF) - the maximum
permissible charging weight in line with TRGS must be marked on
the container prior to connection for filling.
- Compressed-gas containers marked with the maximum
permissible charge pressure in bar (psi) at 15 ºC (59 ºF) must
be filled manometrically. If, at the time of filling, the
temperature is not 15 ºC (59 ºF), the pressure corresponding to
the prevailing temperature must be established; it must be
ensured that the permissible charge pressure at 15 ºC (59 ºF) is
not exceeded in the compressed- gas container. The charged
containers are to be checked by way of random pressure
measurements to determine possible overfilling.
- Compressed-gas containers on which the maximum permissible
capacity is indicated by the net weight (filling weight,
permissible weight of fill) in kilograms must be filled
gravimetrically. The containers are to be weighed during filling
and subsequently subjected to a weight check on special scales
to establish possible overfilling. Scales used for this purpose
must be calibrated.
- Under certain conditions, gases with a critical temperature
greater than or equal to 70 ºC (158 ºF) may be transferred
volumetrically from compressed-gas containers with a maximum
volume of 150 l to compressed-gas containers with a volume of
maximum 1000 ccm. The stipulations of the TRGS apply to the
transfer of liquefied gas to cylinders used by workmen.
- Different TRGS applies to containers in vehicles:
- For gas with critical temperature ≥ +70 ºC (158 ºF).
- For industrial gas with critical temperature ≥ +70 ºC (158
ºF).
- Liquefied extremely low-temperature compressed gases may be
filled differently according to volume (volumetrically) if the
charging system and/or the containers is/are equipped with
devices for measuring or limiting the volume of the charge and
for measuring the temperature of the charge. When filling
volumetrically, it must be ensured that the permissible charge
weight indicated on the container is not exceeded. To determine
possible overfilling, the filled containers are to be checked
gravimetrically on a calibrated scale or, provided that the
pressurized gases are not highly toxic, volumetrically.
Volumetric checking requires the use of appropriate equipment.
The charging and checking devices must be independent of each
other.
- Charging and check measurements are to be performed by
different people. Check measurements must be performed
immediately upon completion of the filling process.
- Overfilled containers must be drained immediately and in a
safe manner until the permissible fill is attained. The
compressed-gas fill is then to be determined again.
- Specific TRGS 407 components do not or only partially apply
to containers for liquefied, extremely low-temperature
compressed gases which are neither flammable nor toxic; this
does not affect the provisions of road traffic legislation.
- When filling compressed gas containers with liquefied gases
at charging temperatures less than or equal to -20 ºC (-4 ºF),
the compressed gas container (if the container material has not
been tested for temperatures less than or equal to -20 ºC (-4
ºF) ) is not to be released from the charging system for
transportation until the container wall temperature is greater
than or equal to +20 ºC (68 ºF).
Recycling and Disposal Regulations
- Specifications and rules for handling and disposing of
refrigerants and refrigerant oils can be found in the
chemical-climate protection provision and recycling and disposal
regulations. These are valid in Germany. Different
specifications and rules may apply in other countries.
Disposal of refrigerant
Refrigerants intended for disposal are to be transferred to
marked recycling containers, observing the permissible filling
quantity. Refer to the chemical-climate protection provision and
the recycling and disposal regulations in Germany. Different
specifications and rules may apply in other countries.
Disposal of refrigerant oil
Used refrigerant oils from systems employing halogenated
hydrocarbons are to be disposed of as waste subject to special
supervision. They are not to be mixed with other oils or
substances. Proper storage and disposal must be ensured in line
with local regulations. Note the chemical-climate protection
provision and the recycling and disposal regulations, for
example, in Germany. Different specifications and rules may
apply in other countries.
Laws and Regulations
Refrigerant Circuit, Converting R12 to R134a and Servicing
Note
- For environmental reasons and on account of the
corresponding legislation, refrigerant R12 can no longer be
manufactured or supplied. Refrigerant R134a has been developed
as a replacement for R12.
- A/C systems developed and designed for refrigerant R12
cannot however simply be charged with refrigerant R134a. To
ensure trouble-free operation of the air conditioning system
even after conversion, various components of the refrigerant
circuit must be replaced.
- A precise description of the conversion procedure and
information on the servicing of converted refrigerant circuits
can be found in Repair Manual: Air Conditioner with Refrigerant
R12 Parts 2 and 3. (This repair manual is only available in hard
copy).
Refrigerant, Keeping Records
The environmental statistics law requires records to be kept
on the use of refrigerants.
Consequently, motor vehicle workshops may well have to
provide the relevant local authorities with information on their
use of refrigerant. It is recommended to always keep a record
sheet.
Note
- A record sheet no longer needs to be kept in the EU due to a
provision by the European Parliament in 2005. A record sheet is
currently necessary when a use of 50 kg or more in the year (see
also Provision (EU) no.1005/2009).
- It is recommended to keep a record sheet because the local
authorities can request information regarding refrigerant use
starting from a certain amount (currently starting with a use of
20 kg in a year).
- Other provisions may apply in countries that are not members
of the EU.
