Applicant's summary and conclusion

Conclusions:

UVCB is a massive (at Room temperature), that showed in WC (samples grinded prior testing) less than 4% particles below 20µm, and typically D50 above 800 µm. Results can be used to support classification.

Executive summary:

Substance is a massive solid at RT (see picture in IUCLID section 1.4 "sampling protocol") which particle size distribution (IUCLID section 4.5) for a WC sample (ie samples crushed and grinded prior to testing) showed D50 > or equal 832 µm, with particles < 20 µm less than 4% (WC). Routes for exposure to consider is therefore only oral (ie inhalation excluded).
