I doubt that it should necessarily be zero. From my wire and cable days,
there are test methods to determine the halogen  content of "zero
halogenated" materials (bromine is a halogen). Zero concentration is
therefore, a relative term - it could be less than 1%. I think the reason
that there is no maximum concentration specified yet is that there is no
concensus and no harmonised standard test method yet. After all, this is
still a draft proposal.

Subject: Draft RoH Directive



The draft of the RoH Directive bans, effective 1 July 2006, certain
substances in new electrical and electronic equipment with certain listed
exceptions. However, outside the exceptions, no maximum allowable
concentration values of the banned substances is listed. Article 5 provides
for future amendments to specify such maximum concentration values, but the
values do not exist at this time. Thus, it appears that, unless the draft
Directive is revised or amended, the maximum allowable concentration values
of the banned substances are zero parts per million. Am I reading this
correctly?
