6 |7 `/ d  i) x$ MQuestion: In the horizontal safety function standard for degree of protection provided by
enclosures (IP code), IEC 60529, a description of the dust is given in subclause
13.4. However, in the transformer standard the description of the dust divagate a
5 V* q4 ?, J* D8 I5 Ybit as the following wording is added: “and shall have a range of particle size
down to and including 1 +m with at least 50% by weight less than 5 +m”. This
" E1 |2 ^6 u/ G# `7 l" Dmore precise description imply that dust in the dust chamber must be changed
when a transformer is tested, this without any technical reasons. For the future,
can we use the dust specified in IEC 60529 also for transformers?
Decision: The horizontal safety function standard IEC 60529 shall be followed, i.e. the dust
specified in subclause 13.4 can be used.
