4              Interpretation

Applicable definitions of terms or phrases

(1)          If there is inconsistency in the definitions of words or expressions, words or expressions will be interpreted in the following order of priority to the extent of any inconsistency:

(a)           the Act;

(b)          this Determination;

(c)           the standards.

(2)          A word or expression defined in a standard mentioned specifically in section 3 of this Determination has the meaning given to it in the relevant standard.

Note:               Notwithstanding this, for convenience to users, the key terms used to ascertain if a product is covered by this Determination are defined in this Determination.

Applicable version of documents incorporated into standards

(3)          For the purposes of this Determination the applicable version of any:

(a)           standard; or

(b)          other document that:

(i)     is referred to in a standard under the heading ‘Referenced Documents’, or under an equivalent heading in a standard; and

(ii)   must be applied to give effect to this Determination or a standard referred to in this Determination,

 

is the version of the standard or other document that is current on the date this Determination came into force.
