RoHS Compliance Testing
www.sigmatest.org
2
RoHS Compliance Testing has become standard
procedure for most manufacturers, sellers,
distributors, and recyclers of electrical and
electronic components or equipment sold or used
in the European Union.
RoHS is the abbreviated form of Restriction of
Hazardous Substances. Also, it is otherwise known
as Directive 2002/95/EC. You may be wondering how
the RoHS testing came into being. RoHS testing
finds its origin in the European Union. The main
purpose of using RoHS is to prevent the use of
hazardous materials in the manufacturing of
electrical equipment. There are many dangerous
materials and substances that go into the
production of electronics and related equipment.
3
RoHS aims to reduce such substances so as to
create a safer environment for those handling
such products. Dangerous materials cause harm to
those exposed to them during manufacturing,
especially. It also aims to decrease the
pollution caused by such materials in landfills,
during recycling, etc. According to the decision,
all relevant products available after July 1, in
the EU market must go through the RoHS testing
https//www.ypppt.com/
The restricted materials under the Restriction of
Hazardous Substances Directive are Lead,
Cadmium, Mercury, Hexavalent Chromium,
polybrominated biphenyls, polybrominated diphenyl
ethers, and four different phthalates (DEHP, BBP,
BBP, DIBP).
Materials are tested under the RoHS Compliance
Test using portable RoHS analyzers. Otherwise
known as X-Ray Fluorescence or XRF metal
analyzers. They help in screening and verifying
the restricted materials found in the concerned
product. RoHS has been updated and improved over
the years to increase its versatility. RoHS 2 and
RoHS 3 are also available now. With the
introduction of RoHS 3, a different set of
testing must be done to determine levels of the
harmful compounds. These get extracted with a
solvent for further testing.
If you are wondering how RoHS 2 differs from the
initial RoHS, it is simply that RoHS 2, also
known as Directive 2011/65/EU came into being in
July 2011. The scope of the previously
established RoHS was amplified so that it covers
all electrical/ electronic equipment, spare parts
and cables with compliance stated under RoHS 2
depending upon the product category. RoHS 2 is
currently used as a CE-marking directive. RoHS
compliance is put to use for the CE-marking of
products. Each and every manufacturer of
electrical/ electronic products has to follow the
requirements put out by RoHS 2 so as to obtain CE
marking for their products.
4
RoHS compliance testing is used by all companies
that produce EEE appliances, sub-assemblies,
cables, components, etc. RoHS also affects those
companies which are sellers or distributors of
such products. Even those who sell to
distributors, integrators or resellers who make
the product available in the European Union
Market. The Restriction of Hazardous Substances
Directive has a global reach now, it not only
applies to electronic products circulating in the
EU market but also to all the markets worldwide.
RoHS also has application in the metal industry
for any usage of metal plating, anodizing,
chromating or on any other finishes on EEE
machinery, heatsinks, or connectors.
RoHS Compliance Testing has become standard
procedure for most manufacturers, sellers,
distributors, and recyclers of electrical and
electronic components or equipment sold or used
in the European Union.
The need for RoHS testing is a result of the
Restriction of Hazardous Substances Directive or
RoHS Directive, which became effective on July 1,
2006, as mentioned above. The Directive was drawn
up in the European Union to protect human health
and the environment from hazardous substances, by
restricting the use of six hazardous chemicals in
electrical and electronic products.

first four substances restricted by RoHS in
component material
Mercury (Hg) 100ppm Hexavalent Chromium (Cr
(VI)) 1000 ppm Cadmium (Cd) 100ppm Polybrominate
d Biphenyls (PBB) 1000 ppm Lead (Pb)
 1000ppm Polybrominated Diphenyl Ethers
(PBDE) 1000 ppm Bis(2- Ethylhexyl) phthalate
(DEHP) 1000ppm Benzyl butyl phthalate (BBP)
1000ppm Dibutyl Phthalate (DBP)
1000ppm Disobutyl phthalate (DIBP) 1000ppm
RoHS has set maximum concentration values for
each of these restricted substances. All values
are set at 0.1, except for cadmium with a limit
of 0.01. STRC has the capability to test for
lead, mercury, cadmium and hexavalent chromium.
RoHS compliance testing is performed in our lab
using spectroscopy and wet chemistry methods to
determine the concentrations of these RoHS
substances in test samples. All RoHS testing
results are fully documented in Certified Test
Reports for our customers record.

RoHS and the recast directive RoHS 2 that went
into effect in July 2011 does exempt a number of
materials and products from the requirements set
forth in the Directive earlier and includes
additional restrictions that went into effect on
December 31, 2011.

What is RoHS compliance testing?
RoHS Compliance Testing is also known as RoHS
Detective Testing. It has become customary for
several sellers, manufacturers, recyclers, and
distributors of electronic and electrical
components or equipment sold or used in the
European Union. 
What is RoHS and reach compliance? REACH is
horizontal legislation controlling the risks
associated with chemical substances across their
life cycle, whereas RoHS is product-specific
vertical legislation that focuses on unsafe
substances in electrical and electronic equipment
(EEE). 
Why is RoHS Compliance Significant? RoHS has its
roots in the European Union back in 2003. The
motive of RoHS is to reduce the setting effect
and health impact of electronics. The
legislations main purpose is to make electronics
engineering safer at every stage of an electronic
devices life span.
7
Does RoHS only apply to electronics? RoHS is a
directive, not a regulation. RoHS is expanded to
cover all electrical/electronic devices, cables,
and spare parts with compliance required by July
22, 2019, or sooner depending on the product
category. 
Do labels need to be RoHS compliant? RoHS does
not require any particular labelling. Depending
on your location, surviving by the RoHS
restrictions is also up to the individual
organisation. 
Does RoHS compliant mean lead-free? Lead is the
only RoHS-banned substance of concern for the
integrated circuits manufactured by Maxim
unified, so lead-free products are also RoHS
compliant products.
What is RoHS? The Restriction of Hazardous
Substances Directive 2002/95/EC established in
the European Union restricts and confines the use
of risky materials found in electrical and
electronic products (known as EEE).
What are the restricted materials mandated under
RoHS? Lead (Pb), Cadmium (Cd), Hexavalent
Chromium (CrVI), polybrominated diphenyl ethers
(PBDE), polybrominated biphenyls (PBB), and four
different phthalates (DEHP, BBP, BBP, DIBP) are
the restricted materials mandated under RoHS.
8
Why is RoHS compliance important? The motive of
RoHS compliance is to decrease the environmental
effect and health impact of electronics.
How are products tested for RoHS compliance? RoHS
compliance is tested with the assistance of RoHS
analysers. They are also known as X-ray
fluorescence or XRF metal analysers and are used
for verification and screening of the restricted
metals.
Which companies are affected by the RoHS
Directive? Any business that trades or
distributes appropriate EEE products,
sub-assemblies, components, or cables directly to
EU countries, or sells to resellers,
distributors, or integrators that in turn sell
products to EU countries, is obstructed if they
utilize any of the restricted materials
What is RoHS 2 and how does differ from the
original RoHS? RoHS 2, or the Recast RoHS 2
Directive 2011/65/EU, was available in July 2011
by the European Commission. The opportunity of
the novel RoHS was long-drawn-out to cover all
electronic/ electric equipment, cables, and spare
parts with amenability required by July 22, 2019,
or sooner depending on the product category
RoHS 2 is also a CE- marking directive, with RoHS
compliance now being required for CE marking of
products. As such, all manufactures of
electrical/electronic products must comply with
RoHS 2 before the CE mark can be functional on
their products. The original green RoHS label
with a checkmark is no longer required or used as
the CE mark now includes RoHS compliance.
9
What is RoHS 3 and how does it differ from RoHS
2? RoHS 3, or Directive 2015/863, adds additional
restricted substances (phthalates) to the
original list of six, as cited under REACH
legislation. It also adds Category 11 products.
RoHS3 takes effect on 22 July 2019.
What is RoHS 5/6? RoHS 5/6 refers to the
agreement for 5 out of the 6 restricts substances
(no compliance for lead(PB)). Lead is very
specific applications for Categories 8 and 9 is
also released under Annex III for a few more
years. For detailed information, see RoHS Annex
III Lead Exemptions.
Will, there be a RoHS 4"are there additional
substances that will be restricted in the
future? Maybe Yes! There are discussions (called
RoHS Pack15) that possibly will take place
possibly after the amendment after the inclusion
of seven new substances. Diantimony trioxide,
Beryllium, Nickel (sulphate and sulfamate) and
Cobalt (dichloride and sulphate)
Tetrabromobisphenol A (TBBP-A), Indium phosphide,
and Medium-Chain Chlorinated Paraffins (MCCPs)
are seven additional substances being assessed
How are RoHS and REACH related? Registration,
Evaluation, Authorization, Restriction of
Chemicals (REACH) is a general regulation that
addresses the production and use of chemical
substances and their potential impact on the
environment and human health. REACH is observed
by the ECHA that deals with 197 substances of
very high concern (SVHC) currently. Whereas RoHS
limits substances present in electrical/
electronic equipment (wiring, circuit boards,
components, displays, cabling, sub-assemblies)
10
We can say that all the RoHS restricted
substances are also on the Reach restricted list.

How are RoHS and WEEE related?
RoHS compliance merges into WEEE by diminishing
the number of risky chemicals used in electronics
manufacture. RoHS controls the risky substances
used in the manufacture of electronic and
electrical equipment (EEE), while WEEE regulates
the discarding of this same equipment.
How is RoHS and the ELV Directive related?
European Union End of Live Vehicle (ELV)
Directive relates to automobiles, whereas the
RoHS directive safeguards a wide array of
electrical and electronic products across
numerous industries.
How is RoHS related to Conflict Minerals (T3G)?
In the major form of Full Materials Declarations
(FMD). Often an arrangement declaration will list
RoHS, REACH, and Conflict Minerals (T3G)
together. Under the Dodd-Frank Act, entirely
publicly traded companies must report being the
SEC the origin of conflict minerals.
11
Does RoHS apply to batteries?
No! The Battery Directive restricts the use of
lead to 0.004, mercury to 0.0005, and cadmium
to 0.002 (medical devices/equipment and
emergency/alarm systems are excluded for cadmium.
Does RoHS apply to RFID tags?
Yes, both active RIFDs and Passive come under
RoHS.
Does RoHS apply to printer cartridges?
Yes, if the cartridge contains electrical parts
that require electric currents or electromagnetic
fields to function. Printer cartridges that
merely comprise ink and container, without
electrical parts
How is RoHS and HIPAA related?
The healthcare industry is controlled by HIPAA,
with its own compliance requirements. If you
manufacture EEP for the healthcare industry, you
will also need to be HIPAA certified under the
Security Rule.
12
How are RoHS and the cannabis industry related?
RoHS and the cannabis industry are related only
indirectly.
How is RoHS compliance enforced and what are the
penalties?
By national enforcements bodies such as the
National Measurements Office, penalties and fines
for non-compliance can vary significantly amidst
European Unions Countries but compromise fines
and also custody in some member states
How can your workforce be trained to help meet
RoHS compliance?
Your workforce can be trained to help meet RoHS
compliance via digitized and electronic from
mobile devices, IoT, AI Modules, Machine Vision
Systems, etc. However, learning, reskilling and
training the workforce is a never-ending thing.
