RoHS2 Compliance

Directive 2011/65/EU of the European Parliament and of the Council of 8 June 2011

The Restriction of Hazardous Substances (RoHS) Directive places rules upon European manufacturers 

of electrical and electronic equipment. The directives’ aim is to reduce the impact that electronic 

devices have on the environment.

According  to  the  EC  Directive  2002/95/EC,  Michell  Instruments’  products  qualify  as  Category  9, 

Control and Monitoring Equipment. Under the 2002/95/EC Directive, Category 9 products are exempt

 

from compliance with the Directive.

However,  the  careful  design  of  all  Michell  Instruments’  products  takes  into  consideration  the 

requirements of the Directive and, wherever possible, compliance is achieved. All future products 

will  be  developed  entirely  using  compliant  materials.  Furthermore,  Michell  Instruments  is  taking 

active steps to remove non-compliant materials and components from existing products wherever 

these  may  occur.  Presently,  none  of  the  non-compliant  materials  are  known  to  occur  in  Michell 

Instruments’ products.

The new Directive 2011/65/EU (RoHS2) entered into force on 21 July 2011 and required all Member 

States to transpose the provisions into their respective national laws by 2 January 2013.

Under the provisions of the RoHS2 EU Directive 2011/65/EU (Article 3, [24]) defines ‘Control and 

Monitoring Equipment’ specifically as ‘monitoring and control instruments designed exclusively for 

industrial or professional use’.

RoHS2 EU Directive 2011/65/EU states the closing date for compliance of any Control and Monitoring 

Equipment product sold into the EU market place as 22nd July 2017.

However, the careful design policy of all Michell Instruments’ products continues to attain compliance 

in  the  shortest  practical  timescales  and  strives  to  ensure  that  less  than  0.1%  of  total  mass  per 

product,  of  all  non-compliant  materials,  appear  within  them.  Michell  Instruments  continues  to 

monitor suppliers and material sources to ensure that compliance of goods provided is maintained.

Warranty

Unless otherwise agreed, the Supplier warrants that, as from the date of delivery for a period of 12 

months, the goods and all their component parts, where applicable, are free from any defects in 

design, workmanship, construction or materials.

The Supplier warrants that the services undertaken shall be performed using reasonable skill and 

care, and be of a quality conforming to generally accepted industry standards and practices.

Except  as  expressly  stated,  all  warranties  whether  express  or  implied,  by  operation  of  law  or 

otherwise, are hereby excluded in relation to the goods and services to be provided by the Supplier.

All warranty services are provided on a return to base basis. Any transportation costs for the return 

of a warranty claim shall reside with the Customer.
