The CE marking and Declaration of Conformity (DoC) are NI's statements assuring compliance to the European Union Restriction of Hazordous Substances law. The EU RoHS directive currently applies to eight categories of electrical and electronic equipment. Products in Category 9, Industrial Monitoring and Control Instruments are excluded from the RoHS directive until July 2017. Consequently, most of NI's products are outside the scope of the RoHS directive.
