As a general rule, intended release relates to the function or quality of an
article. The release of substances from articles is considered “intended” when it is essential for the end use function or “adds value” to the article.
Example: Release of perfume from a perfumed eraser (function = to erase,
added value / function for convenience = quality of smelling good).
A release is not considered to be intended in the following cases:
● A release occurs during removal of ‘impurities’ from a semi-finished or
finished article during its production process.
Example: A size is added to a fabric to improve its process ability.
Sizes are released during further wet processing of the textile.
● A release occurs during use or maintenance of the article and is meant
to improve the product quality in a wide sense or the safety as a
side effect but the released substances do not contribute to the
function of the article.
Example: Washing of clothes by the consumer where remnants of
different chemicals (dye, softener, starch etc.) from processing are
removed over some washing cycles.
● A release of substances is an unavoidable side-effect of the functioning
of the article. Examples: wear and tear of materials under
conditions with high friction, e.g. break linings, tyres.
● A release of substances formed in a chemical reaction is an
unavoidable side-effect of the functioning of the article Examples:
ozone released from copy machines.

with the use instructions or functionality, even if it could have been
