The compliance and build standard requirements for ozone generators are numerous and vary depending on the type of generator and its application area.
In order for an ozone generator to be sold in the EU it must display a CE mark which indicates that it complies with the relevant EU Directives. These Directives generally include some of:
The Low Voltage Directive (LVD 2014/35/EU)
Electromagnetic Compatibility Directive (EMC 2014/30/EU)
The Restriction of Hazardous Substances Directive (RoHS 2011/65/EU)
The Machinery Directive (2006/42/EU)
To comply with these Directives companies normally build their products to an International Standard adherence to which shows the product meets the essential requirements of the Directive (eg. EN 60335-1 Household and similar electrical appliances – Safety – Part 1: General requirements). A Technical File is then completed and the product is generally self-certified. This route is less expensive than getting approval via a Notified Body.
