NOTE to entry: FPDs may contain a various number of mercury containing lamps as backlight.
3.103
manual treatment of FPD
manual treatment of FPDs is a process for which mercury (Hg) containing lamps are removed in order to
save their integrity to avoid mercury pollution. However, it is acknowledged that during this process some
lamps may be accidently broken resulting in the release of mercury
NOTE to entry: It is recognized that some mercury-containing lamps may be broken prior to arriving at the
treatment facility.
3.104
mechanical treatment of FPD
mechanical treatment of FPDs (e.g. a shredding process) is a procedure that intentionally breaks the
mercury containing lamps within a contained atmosphere, and to de-pollute the mix of materials of
mercury resulting from the treatment
NOTE to entry: Treatment processes where the lamps are mechanically treated together with other fractions (e.g.
shredding of the ‘sandwich’ of laminated materials and glue), are considered to be mechanical treatment operations.

NOTE 101 The headers of this document align with the headers in Technical Specification CLC/TS 50625–3–1
Specification for de-pollution, that do not use defined terms (e.g.: CRT Display and FPD appliance). In the text of this
Technical Specification only defined terms are used (e.g.: CRT equipment, CRT, FPD equipment and FPD).
This subclause also applies to other equipment containing CRT or FPD.
If the treatment operator is not performing any de-pollution activities on the CRT glass or FPD equipment
at their treatment facility, they shall remain responsible for ensuring that the tests set out in this TS are
performed at the downstream treatment facility.
NOTE 102 For plastics fractions that contain Brominated Flame Retardants, 4.4, 8.3 and 8.5 of CLC/TS 50625–3–
1:2015 are applicable. For capacitors 8.2 and Annex C of CLC/TS 50625–3–1:2015 are applicable.
8.2 CRT display appliances – Target value methodology
8.2 of CLC/TS 50625-3-1:2015 is applicable.
8.3 CRT display appliances – Analysis methodology
8.3 of CLC/TS 50625-3-1:2015 is applicable with the following additions:
8.3.101 Residual CRT glass in CRT fractions
The treatment operator shall perform at least one analysis per calendar month on the residual amount of
CRT glass remaining on the fractions and components mentioned below. In accordance with
EN 50625-2-2:2015, 5.6, the limit value for CRT glass in other fractions and components is set as follows:
Limit value for components:
• 4 % CRT glass for deflection coils;
• 8 % CRT glass for electron canon.
Limit value for fractions:
• 2 % CRT glass for crushed or shredded mixed fraction after CRT glass separation composed of e.g.
metal parts, plastics, wood, deflection coils;
• 2 % CRT glass for anti-implosive metal frame and shadow masks (ferrous metal fraction) from the
manual dismantling and splitting of CRT, or from crushing of CRT or CRT equipment. This fraction
can also contain other parts like loud speakers, screws etc., which shall be sorted out from the
sample before the analysis.
NOTE An anti-implosion metal frame might otherwise be known as a metal band or belt.
The components and fractions shall be sampled and analysed in accordance with the sampling
procedures in ‘Annex AA (normative) – CRT and FPD: Sampling protocol’ and ‘Annex BB (normative) –
CRT: Analysis protocol for residual CRT glass in CRT fractions’.
The analyses shall be done on site by adequately trained staff.
8.3.102 Fluorescent coating remaining on cleaned CRT glass
The number of samples for analysis per year depends on the mass of CRT glass treated per year, and
the type of analysis (visual or chemical analysis) chosen, according to the table below.
Table 101 — Number of analysis per year
Mass of CRT glass treated per Number of analysis Number of analysis
year
(CC.3 ‘Chemical analysis (CC.2 ‘Visual inspection
protocol’) protocol’)
< 7 500 tonnes 1 4
7 500 to 15 000 tonnes 2 8
> 15 000 tonnes 4 16
In case of chemical analysis and in accordance with EN 50625-2-2:2015, 5.6, the limit value for sulphur
(S) on cleaned CRT glass is set as follows:
• 5 mg/kg (dry matter) sulphur on cleaned CRT glass.
The cleaned CRT glass is sampled in accordance with the sampling procedures in ‘Annex AA (normative)
– CRT and FPD: Sampling protocol’. All five samples randomly collected according to this annex shall be
separately analysed by the laboratory. The laboratory analysis is done in accordance with ‘Annex CC
(normative) – CRT: Analysis protocol for fluorescent coating remaining on cleaned CRT glass’. Each
sample shall meet the limit value for sulphur on cleaned CRT glass.
NOTE 1 Cleaned CRT glass may be cleaned panel glass, separated funnel glass or a mixture of cleaned panel
glass and funnel glass.
NOTE 2 The decisive element to determine the degree of fluorescent coatings removal is the residual content of
sulphur. The content of sulphur in fluorescent coatings is relatively constant (approx. 21 %) and sulphur is present
only in the fluorescent coatings as zinc sulphide.
8.3.103 Lead content in separated panel glass
When separating CRT glass into panel and funnel glass, the mass percentage of the lead oxide in panel
glass fractions shall not exceed the limit value mentioned below, otherwise such fraction shall not be
considered as panel glass fraction.
The number of samples for analysis per year depends on the volume of CRT glass treated per year in
accordance with Table 101 in 8.3.102 ‘Fluorescent coating remaining on cleaned CRT glass’.
In accordance with EN 50625-2-2:2015, 5.6, the limit value for lead oxide (PbO) in separated panel glass
is set as follows:
• 0,5 % lead oxide by weight for panel glass.
The panel glass shall be sampled in accordance with the sampling procedures in ‘Annex AA (normative)
– CRT and FPD: Sampling protocol’. The laboratory analysis shall be done in accordance with ‘Annex DD
(normative) – CRT: Analysis protocol for the lead oxide in separated panel glass’.
8.4 FPD appliances – Mass balance methodology
8.4.101 Introduction
The mass balance methodology requirement for FPD equipment stated CLC/TS 50625-3-1:2015, 8.4 is
therefore modified in this document as follows:
Rules for determination and calculation of the mercury de-pollution efficiency rates for manual and
mechanical processing of FPD equipment are given in this 8.4. The tests shall be carried out according to
‘Annex EE (normative) – FPD: Main steps for Mass Balance’.
NOTE 1 Mass balance for FPD equipment cannot be used to determine de-pollution efficiency, since there are no
methods to calculate input values, due to the great variety in FPD equipment.
NOTE 2 The mass balance methodology can be combined with the batch test.
8.4.102 Procedure
For a manual treatment process, the amount of broken lamps during the manual treatment process is
considered to be an indicator for mercury de-pollution efficiency. The treatment operator shall perform at
least one analysis of the manual treatment process every year to test the de-pollution of mercury from
FPD equipment.
For a mechanical treatment process, no rules of determination and calculation of the de-pollution
efficiency rates are given. Limit values for a mechanical treatment process are given for the de-polluted
physically smallest shredded mixed fraction, see 8.5.
NOTE 1 For a mechanical treatment process no rules of determination and calculation of the de-pollution
efficiency rates are given, because of lack of technology on sampling and analysis methodology, caused by the
following reasons:
— the amount of mercury in the input streams is not constant (FPD equipment occurs in different types (e.g. LCD,
Plasma, LED, OLED, with mercury containing and non-mercury containing backlights) and different sizes, which
results in an uncontrollable and fluctuating amount of mercury in the input stream;
— the output fractions of the mechanical FPD-treatment process can be rather large (e.g. > 50 mm). Before the
sample can be analysed, a sample preparation step is needed where additional size reduction step is required
(e.g. size reduction to a particle size below 5 mm). During this sample preparation step there is a large risk of
losing mercury. This would result in inaccurate results from the analysis of mercury in the final fractions.
For mechanical treatment processes rules are given to measure and calculate the efficiency of the air
filtration system. The treatment line shall include measurement equipment to quantify the mercury
reclaimed by the air filtration unit. Measurements of mercury emissions to air shall be based on flow rate,
the concentration of mercury and the duration. The emissions to air and the efficiency of the air filtration
system shall be monitored on a regular basis.
NOTE 102 Continuously monitoring of mercury emissions from the air filtration system is preferred.
Ambient air shall be monitored on a continuous basis.
Where water is used in the treatment process, the water filtration systems shall be operating in
accordance with the values mentioned in the permit(s) of the treatment operator. Water filtration systems
shall be monitored on a continuous basis.
NOTE 103 For a water filtration system no rules of determination and calculation of the de-pollution efficiency rates
are given. This is because the water in the filtration system is often used in a closed loop system, where the water is
circulated several times before it is sent for further treatment. Due to accumulated mercury in the water filtration
system (from processing FPD equipment before the batch test is being made) the mercury content in the water
filtration system cannot be used as an indicator for measuring de-pollution efficiency of the water filtration system.
8.4.103 Results
During the manual treatment process, the treatment operator shall ensure that 95 % of the intact backlight
lamps are not broken, according to EE.3 ‘Calculation for manual treatment’.
The target value of the process air filtration efficiency shall be at least 95 % for both manual treatment
and mechanical treatment processes, according to EE.3 ‘Calculation for manual treatment’ and EE.4
‘Calculation and validation for mechanical treatment’.
Emissions of mercury to air shall meet the requirements of local legislation and permitting conditions of
the treatment operator.
NOTE 101 An example of limits for emissions of mercury to air is: 0,05 mg Hg / m or 0,15 g Hg / hour
(Netherlands).
Ambient air shall be according to national occupational exposure limit (OEL) values.
8.5 FPD appliances – Analysis methodology
8.5 of CLC/TS 50625-3-1:2015 is applicable with the following additions:
In the case of mechanical treatment processes of FPD, the treatment operator shall perform at least one
analysis per year on the de-polluted physically smallest shredded mixed fraction. The mercury content in
this fraction shall not exceed the limit value defined below prior to being dispatched to a further treatment
or recycling facility.
NOTE 101 Because of technical issues during sample preparation before analysis, it is not possible to analyse the
complete shredded mixed fraction. Therefore only the physically smallest shredded mixed fraction is sampled and
analysed. It is recognized that sampling results of this fraction may provide a higher than average concentration of
mercury in the mixed fraction.
If the process includes a step of screening to maximum 5 mm, only the fine part shall be sampled and
analysed. Otherwise the fraction collected shall be sieved to a maximum of 5 mm at the time of the
sampling procedure before being sent to the laboratory.
NOTE 102 AA.2.5 ‘Sampling procedure for crushed or shredded mixed fractions from CRT and FPD’ gives specific
requirements for the size of samples to be taken and the size of samples to be sent to laboratories sieving step.
According to EN 50625-2-2:2015, 5.6, the limit value for mercury in FPD treatment fractions that shall
apply is:
• 0,5 mg Hg / kg physically smallest shredded mixed fraction (dry matter).
The de-polluted physically smallest shredded mixed fraction shall be sampled in accordance with the
sampling procedures in ‘Annex AA (normative) – CRT and FPD: Sampling protocol’.
The laboratory analysis shall be done in accordance with ‘Annex FF (normative) – FPD: Analysis of the
de-polluted physically smallest shredded mix fraction of flat panel displays’.

CRT and FPD: Sampling protocol
AA.1 Introduction
These sampling protocols are based on EN 14899, which aims at obtaining representative laboratory
samples of output fractions from WEEE treatment operations to enable the performance of laboratory
tests.
A minimum mass as required by EN 50625-1:2014, Annex D, Table D.1, or one days’ average input if the
normal day to day mass is less, shall be used for sample taking.
NOTE The normal day to day mass that can be treated is calculated based on the normal applied production
conditions (i.e. number of shifts, working hours per shift, throughput per hour).
Specific attention shall be given to avoid exposure to mercury during processing the batch (e.g. during a
manual sample preparation step).
Two sampling procedures can be applied depending on the design of the process: sampling during a
treatment process and sampling after the treatment process, according to AA.3 ‘Principles of sampling
and sample preparation’.
AA.2 Sample number and size
AA.2.1 Deflection coils and electron canons from CRT treatment
A minimum of 20 deflection coils and 20 electron canons shall be selected at random for analysis.
AA.2.2 Ferrous metal fraction from CRT treatment
The treatment operator shall provide a container sufficient in size for the sampling procedure. It should be
filled with a minimum of 250 kg ferrous metal fraction, which shall be the sample to be analysed.
