(c)the name of any substance is its chemical name, and to the extent that there is any inconsistency between the CAS No. and the name, the name shall take precedence over the CAS No., and
(d)references to specific migration are to be taken to mean specific migration as measured in accordance with Schedules 3 and 4.
2. If a substance appearing in Part I of this Schedule as an individual compound also falls within a generic term which appears therein, the restriction (if any) applying to that substance shall be that indicated for the individual compound and the entry applying to the generic term shall be treated as varied to such extent (if any) as is necessary therefor.

(a)substances undergoing polymerisation (which shall be taken to include polycondensation, polyaddition or any other similar process) to manufacture macromolecules,
(b)natural or synthetic macromolecular substances used in the manufacture of modified macromolecules, if the monomers required to synthesize them are not so identified, and
(c)substances used to modify existing natural or synthetic macromolecular substances.
(2) If a substance identified in Part I of this Schedule is an acid, a phenol or an alcohol and has salts (including double salts) of one or more of the following names (that is to say salts (including double salts) of aluminium, ammonium, calcium, iron, magnesium, potassium, sodium or zinc), then any such salts (including double salts) shall be treated as included in the specification of that substance.
(3) If, as indicated in paragraph 2 of Annex II to the Directive, a substance is identified in Part I of this Schedule as an “ ... ... ... ... acid, salt” and has salts of one or more of the following names (that is to say salts of aluminium, ammonium, calcium, iron, magnesium, potassium, sodium or zinc), then the free acid corresponding to that substance is not treated as included in the specification of that substance.
