O The applicability of a requirement to a particular classification is indicated in the table by the following. X
indicates that 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
indicates that if the component part exists, the requirement shall be met. Note1 The absence of X or O indicates that no requirement is met. Note2 For class II footwear, it is usual to have no insole present. However, if a removable insock is used, Table 3 is applicable, only chromium VI and pH requirements are fulfilled for leather materials. Note3 Stockings covering the last before the moulding process are not considered as a lining. SIST EN 13832-3:2019
