This information is being provided in an effort to assist Onset customers who are researching the impact of the European Union’s RoHS and WEEE directives on their business. The initial directives referred to in this correspondence are Directive 2002/95/EC dated 1/27/03 for RoHS, and Directive 2002/96/EC dated 1/27/03 for Waste Electrical and Electronic Equipment (WEEE).

This information is based on our current understanding. It is the responsibility of each Onset customer to determine how the RoHS and WEEE directives apply to their own products, or products that incorporate an Onset product. Please do not hesitate to contact Onset's Director of Quality at EUREGS@onsetcomp.com if you have questions concerning Onset's position regarding the WEEE and the RoHS directives.

WEEE Statement

The WEEE directive is intended to prevent waste consisting of electrical and electronic equipment from being introduced to the waste stream, and places the responsibility for disposal, and or recycling, of WEEE on its producer. The WEEE directive also defines 10 product categories for differentiating electrical and electronic equipment covered by it and the RoHS directive. As of the directive’s effective date of August 13, 2005, all our applicable products are labeled with the WEEE-approved recycle bin marking (see below)
