  1. 300 mm TL
  2. TL Tended line
  3. TL = total length; CL = carapace length.
  4. ‘It is up to each Member State to designate the Scheme operator of the TSL implementation of the Member State TL.’;
  5. In Annex I to Regulation (EC) No 2501/2001, after the entry ‘TL’ the name ‘East Timor’ is replaced by ‘Timor-Leste’ and a cross is added to column H.
  6. The presence of a scanner that uses cold cathode fluorescent lamp (CCFL) technology or a technology other than CCFL, such as light-emitting diode (LED), halogen, hot-cathode fluorescent tube (HCFT), xenon, or tubular fluorescent (TL) technologies.
  7. Estimate the lag phase duration tL from the degradation curve (semi-logarithmic plot) by extrapolating its linear part to zero degradation or alternatively by determining the time for approximately 10 % degradation (see Figures 1a and 1b).
  8. The presence of a scanner that uses cold cathode fluorescent lamp (CCFL) technology or a technology other than CCFL, such as light-emitting diode (LED), halogen, hot-cathode fluorescent tube (HCFT), xenon, or tubular fluorescent (TL) technologies. This adder is applied only once, regardless of the lamp size or the number of lamps/bulbs employed.
  9. Estimate the lag phase duration tL from the degradation curve (semi-logarithmic plot) by extrapolating its linear part to zero degradation or alternatively by determining the time for approximately 10 % degradation (see Figures 1a and 1b). From the semi-logarithmic plot, estimate the first order rate constant, k, and its standard error by linear regression of ln (residual 14C activity or test substance concentration) versus time.
