1  Polymers of low concern
  For the purposes of this instrument, a polymer is a polymer of low concern if:
 (a) one of the following applies:
 (i) the polymer has a number average molecular weight that is greater than or equal to 1,000 g/mol, but less than 10,000 g/mol, and has such other characteristics relating to weight as are set out in clause 2;
 (ii) the polymer has a number average molecular weight that is greater than or equal to 10,000 g/mol and has such other characteristics relating to weight as are set out in clause 3;
 (iii) the polymer is made solely from prescribed reactants and has molecules that contain 2 or more carboxylic acid ester linkages, one or more of which links internal monomer units together; and
 (b) the polymer has a low cationic density; and
 (c) the polymer does not have any known hazard classification; and
 (d) the polymer is stable (within the meaning given by the Guidelines); and
 (e) the polymer contains, as an integral part of its composition, at least 2 of the chemical elements set out in clause 5; and
 (f) the polymer does not contain, as an integral part of its composition (other than as an impurity), an element other than a chemical element set out in clause 6; and
 (g) the polymer does not contain, as an integral part of its composition (other than as an impurity), 0.2% or more (by weight) of any combination of the chemical elements set out in paragraphs 6(s) to (zc); and
 (h) the polymer does not contain any difluoromethylene or trifluoromethyl groups; and
 (i) if the polymer is capable of absorbing its own weight in water—the number average molecular weight for the polymer is less than 10,000 g/mol.
