2. Parts per million (p.p.m) figures have not been inserted as in the other standards, because the mg/litre figures are, in fact, parts per million on a weight/volume basis.

3. This data is extracted from a translation of the original standard in Chinese. Reference should be made to the original standard to authenticate any details.
