Lighting Distribution Unit safety standard
BS 8488 states that “for dated references, only the edition
cited applies.” BS 5733 is dated as 2010. This means that
where BS 5733 is specified e.g. “it shall conform to BS 5733
and be classified as a lighting distribution unit as defined in
BS 5733” it is a requirement that the product complies with
the BS 5733: 2010.
Conformity with BS 5733:2010 is of particular significance
for an LDU, as a critical characteristic, is the suitability of the
LDU for electrical stresses associated with lighting loads.
The amendment to BS 5733 July 2010 acknowledged these
stresses and introduced new testing requirements. Therefore,
it is a requirement of BS 8488 that an LDU complies with BS
5733: 2010 (see figure 10).
“ It is a requirement of BS 8488 that an
LDU complies with BS 5733: 2010 ”.
