NOTE The applicability of a requirement to a particular classification is indicated in this Table by the following:
X the requirement shall be met. In some cases the requirement relates only to particular materials within the
classification — e.g. pH value of leather components. This does not mean that other materials are precluded from
use.
O if the component part exists, the requirement shall be met.
The absence of X or O indicates that there is no requirement.
*  Means that if the property is claimed, the requirement given in the appropriate clause shall be met.
