• Restriction of Hazardous Substances
• European Directive (2011/65/EU)
• Requiring CE marking
• Covers majority of electrical equipment
• Temporary exemptions where technical alternatives are missing
The RoHS directive
2
• Lead
• Cadmium
• Chrome VI
• Mercury
• Bromine compounds
The substances
3
• Polybrominated Biphenyl (PBB)
• Polybrominated Diphenylether (PBDE)
• Cadmium: 0.01% (100ppm)
• Others: 0.1% (1000ppm)
• Homogenous material
Limits - 0.1% of what?

Test everything
2 ways to comply with RoHS
EN 62321 series
System to
check suppliers
EN 50581:2012
Method 1 – Test report
7
Sample Unit Cd Cr Pb Br Hg Result
1 Metal core % ND 0.07 0.02 ND ND Pass
2 Metal surface 1 % ND 0.07 0.15 ND ND Fail
3 Metal surface 2 % ND 0.15 0.06 ND ND Inconclusive
4 Insulation wire - red % ND ND ND 0.05 ND Inconclusive 0.05
ND = Not Detected
Method 2
Quality Assurance
standard EN 50581:2012

Safeguarding RoHS compliance through quality system
-Shall be done through risk assessment of
suppliers vs. probability of RoHS non-compliant parts
WHY!
Methode 2
9
Could have been easy- you buy from component manufacturer
10
Component/Material
RoHS Documents
Everything okay? Checked
Componentmanufacturer
Most often the case!

Documents for RoHS found on Internet
Can I trust that I got the real component and that the documentation is correct????
Additional sourcing
Componentmanufacturer
In the same way as for method 1- Your product and the Bill of Material-BOM list
• What shall the BOM contain:
• List of components and parts-with relevant data
• Identification of the part
• Your identification of the part
• The suppliers identification
• The manufacturers identification
• Cross reference between the product / component / material and your compliance file
Where do you start?
12
Need drawing photos showing relationship between product and
TCF
13
You buy from:
1.Manufacturer
2.OEM manufacturer
3.Authorized Representative
4.Component vendor with good quality systems
5.Component vendor without QA system

Documents to request:
17
Part Supplier ID.
Material Declaration
Analytical Test reports
Contractual Agreements /supplier declarations
Material-Enclosure11 Du Pont Yes
Component part 4478
399-5444-3-ND
YES
Sub assembly-PCB 14 466-312 DOC
Material declaration /analytical testing based on own analyzes or third party,audit, quality certification – etc.
Decide what documentation to request from your supplier based
on risk category
18
• Are international accepted standards used, like EN 62321-series,(IEC 62321-xx)?
• Are exemptions used, and are they valid- when expire-note in TCF?
• Are data considered to be of sufficient quality or trustworthiness?
• Missing documents?
If everything found satisfactory-into Technical File
Evaluation of incoming documentation
19
Evaluate each document if it meets the
substance restriction
• If no, determine further action-like......
• Additional testing
• Additional information
• Change component
• Change supplier
If no?
20
We shall have a technical file for our product.
Shall consist of following:
Completing our technical file
21
Description of product
Technical documentation for materials, parts or
sub-assemblies
Relationship between product and file
List of harmonizedstandards – in this
case EN 50581:2012
Review periodically the technical file
Check if techical files is still valid
Check for updates in Components, Materials
Exemptions, Standards, Legislation etc
Check suppliers, especially for new
Check for obsolete components (establish
early warning systems)

What is new
Ukraine has implemented EU RoHS and
require full TCF-technical file.
UAE- In process of implementing
Final review of last batch of exemption
applications for Annex III with commenting
deadline December 1st, 2017.
Amendment to RoHS 2 of November 15th,
with scope changes and adopting to circular
economy.
