Introduction
In order to support EN 50625-2-2 Treatment requirements for WEEE containing CRTs and flat panel
displays and thereby fulfil the requirement of the European Commission’s Mandate M/518, it is necessary
to include normative requirements (such as target and limit values for the analysis) into a document,
which is able to be revised in the future, to take into account both practical experiences and changes in
treatment technologies.

3 Terms and definitions
Clause 3 of EN 50625-1, EN 50625-2-2 and CLC/TS 50625-3-1:2015 is applicable, with the following
additions:
3.101
deflection coil
copper coil located on the CRT funnel that deflects electron beams emitted by electron canon
NOTE to entry: The electron canon may be otherwise known as an electron gun.
3.102
Flat Panel Display
(FPD)
assembly of components that use technologies that produce and display an image without the use of
cathode ray tubes
[Source EN 50625-1:2014, 3.16, modified with the abbreviation FPD]
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.

4.4 Analysis methodology
4.4 of CLC/TS 50625-3-1:2015 applies with the following additions:
Basic principles of processing heterogeneous samples from CRT and FPD treatment fractions are given
in ’Annex BB (normative) – CRT: Analysis protocol for residual CRT glass in CRT fractions’, ‘Annex CC
(normative) – CRT: Analysis protocol for fluorescent coating remaining on cleaned CRT glass’, Annex DD
(normative) – CRT: Analysis protocol for the lead oxide in separated panel glass’ and ‘Annex FF
(normative) – FPD: Analysis of the de-polluted physically smallest shredded mix fraction of flat panel
displays'.
The above mentioned annexes list examples of proven procedures to be used for sample preparation and
for analytical methods. These methods shall be used in the first instance. However, if an alternative
method of sample preparation or analytical method is to be used other than one of the applicable
methods given in these annexes, the laboratory shall validate the alternative method in accordance with
EN ISO/IEC 17025, 5.4.5.
The laboratory shall document a full description of the procedure, together with a full report on the
validation process.
As a minimum, the validation process shall comprise of:
• the calibration details using reference standards or reference materials;
• a comparison of the results achieved against the results achieved with the methods given in the
annexes mentioned above;
• an assessment of the uncertainty of the results;
• an assessment of the influence of the specific character of the material to be analysed, including size
distribution and heterogeneously. Specifically, for the analysis of fluorescent coating on cleaned CRT
glass, the laboratory shall take into account the informative ‘Annex GG (Informative) – CRT:
Background on analysis protocol for fluorescent coating remaining on cleaned CRT glass’ and the
studies it refers to. Specifically, for the analysis of mercury in shredded FPD fractions, the laboratory
shall take into account the fact that the mercury is expected to be metallic and on the surface of the
material and thus not dispersed in the matrix. The influence of the volatility of mercury on the results
shall be reported.
4.101 Monitoring methodology
4.101.1 Introduction
The treatment operator shall monitor the de-pollution activities at the treatment facility, in accordance with
the requirements of this TS.
The treatment operator shall also monitor the information provided by downstream treatment operators as
set out in 4.4 and Annex C of EN 50625-1:2014 (summarized in Table G.1) for all fractions that leave the
treatment facility until end of waste status is reached or until the WEEE or fractions thereof are recycled,
recovered, or disposed of.
4.101.2 CRT equipment
The treatment operator shall have a documented procedure showing the methodology of the CRT glass
removal process from deflection coils; electron guns; crushed or shredded mixed fraction; anti-implosive
metal frame and shadow masks (ferrous metal fraction); the removal of fluorescent coating from the CRT
glass and the limitation of lead oxide in panel glass fractions. This shall include at least:
— the methodology describing the removal processes;

---------------------- Page: 11 ----------------------

SIST-TS CLC/TS 50625-3-3:2017
CLC/TS 50625-3-3:2017 (E)
— the parameters of these processes that indicate the effectiveness of the operations;
— the range of acceptable parameters used by the treatment operator;
— the frequency and method of the monitoring of these parameters;
— the reporting and analysis records shall be stored in accordance with Clause 6 of EN 50625-1:2014.
The procedures for the treatment activities performed by the treatment operator at the treatment facility
need to be included in this document. Also the treatment operator shall include measures to avoid loss of
fluorescent powder during compacting the CRT, storing, handling and (if applicable) shipping.
Diffuse emissions to the air and within or out of containers of fluorescent powders are a risk to health and
environment and should be avoided.
4.101.3 Flat Panel Display (FPD)
The treatment operator shall have a documented procedure showing how they remove mercury or
mercury containing lamps from the FPD equipment. This shall include at least:
— the description of the mercury removal process (for mechanical treatment operations) and/or
capturing process (for manual and mechanical treatment operations);
— the parameters of these processes that indicate the effectiveness of the operation;
— the range of acceptable parameters used by the treatment operator;
— the frequency and method of the monitoring of these parameters;
— the reporting and analysis records shall be stored in accordance with Clause 6 of EN 50625-1:2014.
Only the procedures for the treatment activities performed by the treatment operator at the treatment
facility need to be included in this document.
