This clause of Part 3-1 is replaced by the following:
4.101 Introduction
The following paragraphs cover de-pollution monitoring and refer to EN 50625-2-3:2017, 5.6. The target
values and limit values set in this Technical Specification apply to the three elements stated EN 50625-2-
3:2017, 5.6.101.
All target values and limit values stipulated in this Technical Specification take measurement uncertainty in
weighing, sampling and analysis procedures into account. Therefore, all actual measured and calculated
values are deemed to be final irrespective their variances.
4.102 Monitoring and evaluation system and regular reporting
4.102.1 General
According to EN 50625-2-3, 5.6.102, the treatment operator shall monitor the input and output information of
step 1, step 2 and step 3 treatment of the plant on a day-to-day basis.

---------------------- Page: 8 ----------------------

SIST-TS CLC/TS 50625-3-4:2017
CLC/TS 50625-3-4:2017 (E)
The monitoring system shall demonstrate the performance in daily business. The role of the monitoring
system is an internal control system for the treatment operator to measure and evaluate the daily performance
of his plants, especially with a view of the removal, capturing and subsequently disposal or recovery of VFC
and VHC. Target values and limit values are set as minimum requirements for the day-to-day business.
If the treatment operator doesn’t reach the target values, or exceeds the limit values of the day-to-day
business, he shall activate corrective actions and monitor and document the related results.
4.102.2 Requirements for day-to-day business of step 1 treatment plants
4.102.2.1 Target values for refrigerant and oil output masses.
The target values (90 % of the expected masses) of removed and captured VFC- and VHC - refrigerants shall
be calculated on the basis of the actual weekly input to the plant.
The expected mass of removed and captured VFC refrigerant for class 1 appliances to class 4 appliances is
deemed to be 0,113 kg of refrigerant per intact refrigerating system. The expected mass of removed and
captured VHC is deemed to be 0,054 kg per intact refrigerating system accordingly for class 1 appliances to
class 4 appliances.
If there is evidence that the expected masses of VFC and VHC of class 1 appliances to class 4 appliances are
varying locally from the values set above, the actual values have to be taken into account as a base for the
calculation of the target values. Performance tests with solely VHC or VFC appliances of class 1 appliances to
class 4 appliances are deemed to be clear and comprehensible evidence. For those tests, at least 300 VHC or
VFC appliances in each case have to be taken as a sample. For day-to-day monitoring of removed and
captured VFC and VHC output from class 5 appliances and class 6 appliances the expected mass of
refrigerant shall be based on local key figure values representing the normal supply to the respective plant.
The monitoring data shall give plausible evidence for the values taken as expected VFC and VHC masses.
The expected mass of oil in class 1 VFC appliances to class 4 VFC appliances is deemed to be 0,240 kg oil
per VFC containing compressor.
The expected mass of oil in class 1 VHC appliances to class 4 VHC appliances is deemed to be 0,160 kg oil
per VHC containing compressor.
If there is evidence that in a country or in a region the expected mass of oil differs to the value of 0,240 kg or
0,160 kg, this value shall be used. Performance tests with solely VHC or VFC appliances of class 1 to 4 are
deemed to be clear and comprehensible evidence. For those tests, at least 300 VHC or VFC appliances in
each case have to be taken as a sample.
For day-to-day monitoring of oil from class 5-6 VFC and VHC appliances the expected mass of oil shall be
based on local values representing the normal supply to the respective plant.
NOTE Since the oil from radiators, which fall under class 6, is required to be kept separate from the oil from
refrigerating systems, this oil is not considered in the day-to-day monitoring.
The normal supply of class 5-6 VFC and VHC appliances shall be regularly tested, evaluated and documented
in order to fix local key figures.
The overall target value in kg for the classes 1-6 appliances regarding the day-to-day monitoring for step 1
treatment plants [expected mass refrigerant in kg] shall be calculated on base of the following:
TargetValue = TargetValue + TargetValue + TargetValue +
VFC;VHC,step 1 VFC;step1,1-4 VHC;step1,1-4 VFC;step1,5-6
TargetValue
VHC;step1,5-6
In cases where the output refrigerants are not captured in vessels but converted in a step 3 plant, the output
raw gas data (mass flow of VFC and VHC) of step 1 treatment shall be taken to calculate output masses
during the day-to-day performance according to Annex HH. In those plants the value for
TargetValueVFC;VHC,step1 shall be calculated analogously to those step 1 treatment plants where the refrigerants
are captured in vessels.
The mass of actual weekly removed and captured or converted refrigerant shall be equal or higher
than TargetValue
VFC;VHC,step 1.

SIST-TS CLC/TS 50625-3-4:2017
CLC/TS 50625-3-4:2017 (E)
The monitoring of the oil output masses from classes 1-6 appliances shall be done analogously to the
monitoring of the refrigerant masses.
The target value for the removal and capturing of oil shall be calculated analogously to the target value for
refrigerants.
4.102.2.2 Further requirements concerning step 1 treatment
4.102.2.2.1 Monitoring of input and output masses in step 1 treatment
The overall weekly mass balance of all input masses and all output fraction masses in step 1 treatment shall
not differ more than 5 %.
4.102.2.2.2 Limit value for residual refrigerant content in oil
According to EN 50625-2-3:2017, 5.6.102.9, the treatment operator shall take samples of oil and send them to
the laboratory. Sampling and analysing shall be done on the basis of Clause 12 of this Technical
Specification.
The limit value for the residual refrigerant (VFC / VHC) in the output oil is 0,2 %.
4.102.2.2.3 Limit value for residual oil in compressors
According to EN 50625-2-3:2017, 5.6.102.9, there shall be a monthly analysis of remaining oil masses in
compressors directly after leaving the step 1 suction process and compressors designated to send for further
treatment at an acceptor facility.
All oil shall be considered removed in step 1 treatment if the residual amount of oil in the compressors is in
average less than 15 g (=limit value) directly after the suction process. Compressors leaving the treatment
plant for further treatment shall have no oil to the greatest possible extend (non-dripping). All oil removed from
the compressors (including the oil removed before the compressors are leaving the treatment plant) shall be
degassed.
NOTE It is acknowledged that current techniques do not remove the oil that is caught in the compression chambers.
For the purpose of these requirements, the treatment operator shall control at least 3 compressors directly
after the suction process and at least 3 compressors leaving the plant. For the evaluation of the evacuation
performance, the evacuated compressors shall be opened horizontally. That has to be done at a height of
approximately 2/3 with a flexible-blade saw so that the motor can be removed. The remaining quantity of oil
shall be determined and recorded. The procedure shall be documented by photographing it.
If the average residual amount of oil in the opened compressors directly after the suction process exceeds the
limit value of in average 15 g then the residual amount of 10 further compressors shall be determined. If the
limit value is still exceeded, measures to optimize the suction process have to be taken. The measures shall
be documented and photographed and a new analysis shall be performed to verify their efficiency until the
problem is solved.
4.102.2.2.4 Limit value for residual VFC in output refrigerants and oil at VHC step 1 treatment plants
According to EN 50625-2-3:2017, 5.6.102.4 and 5.6.102.9, all output refrigerant and oil vessels of step 1
treatment plants, designated to remove and capture entirely VHC, shall be controlled regarding the content of
VFC. Sampling and analysing of the vessels shall be done in accordance with Clause 12 of this Technical
Specification. The limit value for residual VFC in output VHC refrigerants and oil in the vessel is 0,01 %.
NOTE This limit value is derived by taking into account the lower detection limit.
This requirement is also applicable for the VHC stream of step 1 treatment plants where VFC and VHC
appliances are treated in separate batch streams.
All measurement procedures shall be subject of documentation.

4.102.2.2.5 Limit value for phased out VFCs in non-phased out VFCs claimed for recycling
According to EN 50625-2-3:2017, 5.6.102.4, all output refrigerant and oil vessels of step 1 treatment plants,
designated to remove and capture only non-phased out VFC, shall be controlled regarding the content of
phased out VFC. Sampling and analysing of the vessels shall be done on in accordance with Clause 12 of this
Technical Specification. The limit value for phased out VFCs in non-phased out VFCs refrigerants in the
vessel is 0.01 %
NOTE This limit value is derived by taking into account the lower detection limit.
4.102.3 Requirements for day-to-day business of step 2 treatment plants
4.102.3.1 Monitoring of input and output masses in the step 2 treatment
The overall weekly mass balance of all input masses and all output fraction masses in step 2 treatment shall
not differ more than 5 %.
4.102.3.2 Target value for blowing agent output masses
4.102.3.2.1 General
The expected masses of removed and captured VFC- and VHC - blowing agents shall be calculated on base
of the actual weekly input to the plant.
Starting point for the calculation is the actual mix of VFC- and VHC - class 1 appliances to class 6 appliances,
the respective foam weight wi of the different classes and the potential concentration of the blowing agent (fVFC
and fVHC) in the original polyurethane foam before treatment. Missing doors have to be considered as being
20 % of the foam mass of the respective appliance and the respective appliance class.
Furthermore, other VFC/VHC sources in the input have to be considered for the calculation.
The following values for the concentration of VFC in VFC-polyurethane (input) and values for the
concentration of VHC in VHC-polyurethane (input) (fVFC / fVHC) are applicable in all European countries:
• fVFC = 82 g/kg
• fVHC = 38 g/kg
For class 1 appliances to class 6 appliances the mass of expected VFC- blowing agent during the weekly
evaluation period on base of the number (Ci) of VFC –polyurethane containing appliances per class treated is
to be calculated as follows:
6
M w× fC×
VFC;1−6 ∑ i;VFC VFC i;VFC
i=1

Analogously the mass of expected VHC- blowing agent during the weekly evaluation period on base of the
number (Ci) of VHC –polyurethane containing appliances per class treated is to be calculated as follows:
6
M w× fC×

VHC;1−6 ∑ i;VHC VHC i;VHC
i=1
For other materials containing VFC or VHC the expected mass of blowing agents are to be calculated on base
of the actual total foam mass (w and w ) and the concentration of VFC and VHC in the
VFC;other VHC;other
polyurethane before treatment as follows
M = w x f
VFC;other VFC;other VFC
M = w x f

SIST-TS CLC/TS 50625-3-4:2017
CLC/TS 50625-3-4:2017 (E)
The total mass of expected blowing agents as result of the treatment of all input foam sources is to be
calculated as:
M = M + M + M + M
tot VFC;1-6 VHC;1-6 VFC;other VHC;other
The target values in kg for the VFC- and VHC masses to be removed and captured during the weekly
evaluation period to be calculated as follows:
T = [M M ] x 0,9
VFC;step2 VFC;1-6 + VFC;other
T = [M M ] x 0,9
VHC;step2 VHC;1-6 + VHC;other
Consequently, the target value for the total mass of minimum to be achieved removal and capturing of blowing
agents is T = M x 0,9
tot;step2 tot
In cases where the output blowing agents are not captured in vessels but converted in a step 3 treatment
plant, the output raw gas data (mass flow of VFC and VHC) of step 2 treatment shall be taken to calculate
output masses during the day-to-day performance according to Annex HH. In those plants, the value for
tvVFC;VHC,step 2 shall be calculated analogously to those step 2 treatment plants where the blowing agents are
captured in vessels.
The mass of actual removed and captured or converted blowing agents per week shall be equal or higher than
Ttot,step2.
4.102.3.2.2 Individual foam masses of class 1 appliances to class 3 appliances containing VFC or VHC
The individual foam masses wi,VFC and wi,VHC of class 1 appliances to class 3 appliances containing VFC or
VHC are:
For the Northern European countries:
• wNi,VFC: cl. 1: 3,66 kg; cl. 2: 4,88 kg; cl. 3: 6,10 kg;
• wNi,VHC: cl. 1: 3,30 kg; cl. 2: 6,30 kg; cl. 3: 8,30 kg;
For the Mid European countries:
• wM : cl. 1: 3,14 kg; cl. 2: 4,18 kg; cl. 3: 5,23 kg;
i,VFC
• wM : cl. 1: 3,30 kg; cl. 2: 6,30 kg; cl. 3: 8,30 kg;
i,VHC
For the Southern and Eastern European countries:
• wSE : cl. 1: 2,45 kg; cl. 2: 3,26 kg; cl. 3: 4,08 kg;
i,VFC
• wSEi,VHC: cl. 1: 3,30 kg; cl. 2: 6,30 kg; cl. 3: 8,30 kg;
NOTE 1 Countries are listed in Annex AA.
NOTE 2 Appliance classes are defined in EN 50625-2-3:2017, 3.111 to 3.116.
If there is clear and comprehensible evidence, that numbers for foam masses wi,VFC and wi,VHC of class 1-3
VFC- and VHC- appliances are higher or lower than the average numbers in the geographical area these new
numbers shall be used in the respective country or at the respective local area.
Dedicated tests with only VHC or VFC appliances of one class are deemed to provide clear and
comprehensible evidence. For those tests, at least 300 VHC or VFC appliances in each case of only one class
have to be treated. For the calculation of wiVHC or wiVFC the actual content of foreign matter in the removed
polyurethane foam weight has to be deducted from the gross weight of the polyurethane fraction.
Furthermore, the residual VHC or VFC content in the polyurethane, adhering polyurethane masses on metals
and plastics fractions and fVHC / fVFC have to be taken into account when calculating the original individual foam
