IPXX Zone Classification

For installations of fans in bathrooms and showers

As a result of European standardisation. Amendment 1 of the 17th addition of the IEE Wiring Regulations (BS7671) came into effect in July 2011. This outlined the new zoning and ingress protection criteria for bathroom fans, having effect on product safety and installation location. To achieve IP ratings, fans are rigorously tested using a series of graded water tests. Location advice (i.e. zone 0, 1 or 2) ensures installers and users are not at risk of installing and operating products in unsuitable areas.
