• 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?

2 ways to comply with RoHS

EN 62321 series

System to

check suppliers

EN 50581:2012

Method 1 - measurements

youtube: Nemko RoHS

Method 1 – Test report

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

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)
