The European Union Directives 2002/95/EC on the restriction of the use of certain hazardous substances in electrical and electronic equipment and 2002/96/EC on waste electrical and electronic equipment are designed to tackle the fast increasing waste stream of electrical and electronic equipment and complements European Union measures on landfill and incineration of waste. Member States are required to introduce legislation to meet these directives by 1st July 2006.
This imposes certain requirements on the re-use and recycling of Electronic equipment at the end of its life. Electrical equipment is defined to belong to one of 10 categories with different requirements for each. Gas analysis instrumentation is likely to fall into category 9, "Monitoring and Control Equipment". This has less onerous requirements than some of the others but will involve marking the equipment with a "crossed out wheelie bin" symbol and making some arrangements for re-use/recycling. The latter may most likely be discharged by belonging to some kind of national scheme involving a levy on items produced. The WEEE directive does not forbid the use of any materials, but no doubt charges for disposal of Toxic and Heavy metals will continue to rise.
The sister directive covers the restrictions on the use of certain highly toxic heavy metals in electrical equipment, of which lead is one. Under the recast RoHS directive lead anodes in electrochemical oxygen sensors have been granted exemption status for use in the following categories of instrumentation in which they are intended to be used;
Directive 2011/65/EU came into force on 22nd July 2014 and we can declare that the Systech Illinois range of analytical instrumentation and sensors comply with the current directive, with the claimed exclusion:
Furthermore the exemption is valid for a further 10 years from this date.
