Mercury quantity per CCFL Hg Q / CCFL: Mercury Quantity per CCFL coming from 17” or 19" LCD monitors Hg Q / CCFL= 2,10 mg +/- 0,7% (i.e. Hg Q / CCFL min = 2,087 and Hg Q / CCFL max = 2,116 mg) See Annex 7, paragraph 2.3. Because the waste FPDs stream is subject to changes with years, such a measurement campaign should be conducted regularly in order to update the above reference values. Number of CCFL per LCD monitor Most 17” and 19” LCD monitors use 4 CCFLs for backlighting. A small percentage, p%, of these monitors can use only 2 CCFLs per unit. N CCFL / unit: number of CCFL per 17” and 19” LCD monitor N CCFL / unit = 4 x (1 + 2 x p% = 4 2 x p% –p%) – With p% = 5/69 (see Annex 7, paragraph 2.2), we obtain: N CCFL / unit = 3,855 Because the waste FPDs stream is subject to changes with years, such a measurement campaign should be conducted regularly in order to update the above reference values. Number of LCD monitors in the reference batch N Unit / RB: Number of Unit (17” or 19” LCD monitors) in the Reference Batch N Unit / RB has to be determined during the preparation of the reference batch before treatment (see paragraph 2.2.1) Incoming mercury quantity In Hg Q: Incoming Mercury Quantity in the reference batch In Hg Q = (N Unit / RB) x (N CCFL / unit) x (Hg Q / CCFL) Measurement of mercury quantity in output streams This paragraph aims to specify the sampling and analysis protocols to measure total mercury quantity in all the output streams which can be present under different forms: solid, liquid and gas. In streams This concerns all the solid output fractions that consist of two different types: fractions that are intended to be recycled (pure or materials) named Fractions for Recycling (FfR); fractions where the mercury is concentrated and that are directed to appropriate disposal named Fractions for Disposal (FfD).
