Predictions of Electronic Equipment. It assumes that no
reliability data is available on the actual units and devices
for which the predictions are to be made, i.e. all predictions
are based on generic reliability parameters.
Compatibility with RoHS requirements
The products are compatible with the relevant clauses and
requirements of the RoHS directive 2011/65/EU and have a
maximum concentration value of 0.1% by weight in
homogeneous materials for lead, mercury, hexavalent
chromium, PBB and PBDE and of 0.01% by weight in
homogeneous materials for cadmium.
Exemptions in the RoHS directive utilized in Flex products are
found in the Statement of Compliance document.
Flex fulfills and will continuously fulfill all its obligations under
regulation (EC) No 1907/2006 concerning the registration,
evaluation, authorization and restriction of chemicals (REACH)
as they enter into force and is through product materials
declarations preparing for the obligations to communicate
information on substances in the products.
