5 Characteristic numbers
5.1 Step 1
5.1.1 Maximal ratio of VFC (according to rating plate) to mass of mixture of VFC and oil sucked off:
t
max
According to A.2.6 c) in EN 50574:2012, a value (t ) for the parameter t shall be specified, above which an
max
individual appliance undergoing step 1 treatment shall be deemed to be defective. The parameter t is
computed as the ratio of the potentially recoverable quantity of VFC to the effective reduction in mass (S )
k
resulting from the vacuum extraction of the refrigerant and oil mix from the refrigerating system. A threshold
value of t = 0,57 shall be used in case of completely emptied compressors.
max
NOTE If the step 1 process does not completely remove the refrigerants and oil, then the t value is not applicable and
has no plausible relation with t .
max
In addition to the evaluation based on t , the quantity of VFC and oil removed by vacuum extraction shall be
max
assessed. A completely emptied refrigerating system shall be deemed as defective if S < 0,24 kg.
k
5.1.2 Ratio of total quantity of VFC and oil recovered by vacuum extraction to the reduction in the
appliance mass after vacuum extraction has been completed: q
Mtot
According to A.2.6 a) in EN 50574:2012, a mass balance analysis shall be carried out by calculating the ratio
(q ) of the sum of the total mass of VFC recovered and the total mass of oil recovered (outR + outL) to the
Mtot
total mass reduction (S) of all appliances after vacuum extraction has been completed. This ratio q is a
Mtot
measure of the total system performance in terms of the overall quantity of oil and refrigerant recovered.
A value of q > 0,95 and < 1,05 is deemed plausible.

5.1.3 Number of oil containing refrigerating system: N
According to A.2.6 e) in EN 50574:2012, the average quantity of oil per refrigerating system is calculated by
dividing the total mass of oil recovered (outL) by the number of refrigerating systems containing oil (N). The
result (V ) represents the quantity of oil recovered per refrigerating system. The parameter N refers to the
L
number of appliances for which S > 0,050 kg.
k
5.1.4 Residual oil in compressors
According to 5.2 (1) in EN 50574:2012 all oil shall be removed from the refrigerating system. All oil shall be
considered removed if the average residual amount of oil in the opened compressors is less than 10 g.
If the average residual amount of oil in the opened compressors according to A.2.6 of EN 50574:2012
exceeds the limit of 10 g then the residual amount of other compressors from the test shall be determined.
NOTE In order to get a representative figure one could measure the total amount of residual oil left in all the
compressors.
5.2 Step 2
5.2.1 Masses of PU for the individual appliance categories VFC 1–3 (i) and VHC 1–3 (i): w and
i,VFC
w
i,VHC
According to Clause 6 in EN 50574:2012, the mass of PU originally present in the individual appliance
categories (w , w , w ) shall be defined. The masses of PU insulating foam in VFC-containing and VHC-
1 2 3
containing appliances in the categories 1–3 vary from country to country or relevant playing field area.
Characteristic numbers for the individual areas are as follows:
• The values for w and w for the Northern European countries are:
i,VFC i,VHC
o wN : cat 1: 3,66 kg; cat 2: 4,88 kg; cat 3: 6,10 kg;
i,VFC
o wN : cat 1: 4,36 kg; cat 2: 5,81 kg; cat 3: 7,26 kg;
i,VHC
• The values for w and w for the Mid European countries are:
i,VFC i,VHC
o wM : cat 1: 3,14 kg; cat 2: 4,18 kg; cat 3: 5,23 kg;
i,VFC
o wM : cat 1: 4,36 kg; cat 2: 5,81 kg; cat 3: 7,26 kg;
i,VHC
• The values for w and w for the Southern and Eastern European countries are:
i,VFC i,VHC
o wSE : cat 1: 2,45 kg; cat 2: 3,26 kg; cat 3: 4,08 kg;
i,VFC
o wSE : cat 1: 4,36 kg; cat 2: 5,81 kg; cat 3: 7,26 kg;
i,VHC
w data are based on a limited number of tests and may be subject to change. If there are clear and
iVHC
comprehensible evidences, that in a single country numbers for w are higher or lower than the average
iVHC
numbers in the geographical area these new numbers shall be used in the respective country.
In case of an appliance without doors the amount of foam of the appliance shall be reduced by 20 %.
NOTE 1 Countries are listed in Annex A.
NOTE 2 Categories are defined in 3.2 of the EN 50574:2012.

NOTE 3 A successful VFC test combined with tests on base of Annex B of EN 50574:2012 with solely VHC appliances
of one category are deemed to be clear and comprehensible evidences.
5.2.2 Concentration of VFC in VFC-PU (input) and Concentration of VHC in VHC-PU (input): f / f
VFC VHC
According to Clause 6 in EN 50574:2012, the concentration of VFC and VHC blowing agents present in the
PU foam contained in appliances shall be defined. The following values are applicable in all European
countries:
• f = 8,5 %
VFC
• f = 3,8 %
VHC
These values are needed in order to calculate the amounts of VFC and VHC that can potentially be expected
to be recovered during plant performance tests and the target values derived from them.
