RoHS Certification

What is RoHS?

In short, the RoHS Directive is a directive adopted by the Council of the European Union in 2003 (2002-95-EC), which stipulates the absence of certain harmful substances in electrical and electronic equipment, cards or materials. RoHS stands for Restriction of Hazardous Substances in English and stands for restricting the use of certain harmful substances in our language. Here, the concept of harmful substances lead, cadmium, mercury and bromide components are included. These substances are dangerous for human health. It is therefore prohibited to use in electrical and electronic equipment.

This directive was issued by the Ministry of Environment and Forestry in 2008 in our country with the title of Regulation on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment. This regulation is known as the EEE Regulation.

The EEE Regulation has been issued for the protection of human health and natural conditions and includes the following regulations:

  • Limiting the activity of certain harmful substances in electrical and electronic devices
  • Determination of activities to be excluded from these limitations
  • Controlling the import of electrical and electronic equipment from abroad
  • Environmentally friendly recycling and disposal of electrical and electronic equipment waste

According to the data released by the European Union, the amount of waste from electrical and electronic equipment and materials in the present case is around 4 in all other wastes. This is the amount of waste that is approaching 7 million tons per year. These figures indicate the extent to which nature is polluted.

Before the RoHS directive, there are mandatory regulations for separate collection and recycling of waste from electrical and electronic equipment and materials. Here, manufacturing companies are held responsible for the completion of these products and are expected to design them with regard to recovery, recycling and degradability.

Under the RoHS directive and the EEE Regulation in our country, the use of the following hazardous substances is prohibited in electrical and electronic devices and equipment to be placed on the market:

  • Lead (Pb)
  • Mercury (Hg)
  • Cadmium (Cd)
  • Plus 6 valued chrome (Cr6 +)
  • Polybrominated biphenyl (PBB)
  • Polybrominated biphenyl ether (PBDE)

In 2008, the Council of Europe expanded the scope of these dangerous substances and prohibited the use of the following substances:

  • Bis (2-ethylhexyl) phthalate (DEHP)
  • Butyl benzyl phthalate (BBP)
  • Dibutyl phthalate (DBP)
  • Diisobutyl phthalate (DIBP)

The devices covered by the EEE Regulation are: information technology and telecommunications equipment, large and small household appliances, lighting equipment, electrical and electronic equipment, toys, entertainment and sports equipment and vending machines, except large-scale stationary industrial vehicles. The EEE Regulation applies only to electrical and electronic equipment on the market, not to products developed for personal use.

According to the said regulation, the obligations of the manufacturers are as follows:

  • Lead, mercury, + 6 valued chromium, polybromide biphenyl and polybromide diphenyl ether substances should not be higher than 0,1 by weight (1000 ppm) and cadmium by weight (0,01 ppm) by weight.
  • Information and documents demonstrating that the products meet these criteria should be kept for five years from the time the product is placed on the market.
  • Each year, by the end of February, the declaration of conformity form attached to the regulation should be completed and sent to the Ministry.
  • The regulations of the Undersecretariat of Foreign Trade should be complied with for electrical and electronic devices and materials to be imported from abroad.

What is RoHS Certificate?

Companies that produce electrical or electronic appliances and household electrical appliances that are frequently used in areas where people live and threaten human health by direct contact or indirect air contact are required to obtain a RoHS certificate. Simply put, the RoHS certificate must be obtained for all components that make up the television sitting in front of each day, as well as for all components such as cables and plastic outer cladding. The chemicals contained in these parts constantly dry and emit serious cancer-causing toxic substances into the air. These substances enter the human body by inhalation and accumulate within a certain period of time and threaten human health.

The maximum acceptable limits for these hazardous substances forbidden under RoHS and their uses are as follows:

Restricted substances

Allowable amount (weight)

Usage areas

Lead (Pb)

Percent 0,1

Solder, active and passive active material, termination terminals, printed circuit board coatings, glass, batteries and batteries

Mercury (Hg)

Percent 0,1

Batteries, switches, sensors, relays, fluorescent lamps

Cadmium (Cd)

Percent 0,01

Electrolysis coatings, plastic materials, sensors, NiCd batteries, sparking contacts

Plus Chrome with 6 (Cr6 +)

Percent 0,1

Chrome coatings

Polybrominated biphenyl (PBB)

Percent 0,1

Flame retardant materials

Polybrominated biphenyl ether (PBDE)

Percent 0,1

Dibutyl phthalate (DBP)

Percent 0,1

Plastics - household products

Diisobutyl phthalate (DIBP)

Percent 0,1

Plastics - household products

Human health and environmental problems have become more important than ever in recent years. Not only in Europe, but also in many parts of the world, public and private organizations are increasingly addressing these problems and seeking solutions. The World Health Organization also supports this work. Therefore, RoHS directive and RoHS certification studies are of great importance. In this sense, the companies that regulate their activities in accordance with the principles of the EEE Regulation and obtain the RoHS certificate make a big profit from this. Here are a few of them:

  • Businesses prove that they value human health
  • It also proves that they are sensitive to nature and that they do production that does not pollute the nature.
  • Businesses have proven that they are engaged in production that gives importance to the recovery of product waste.
  • It proves that during the use of the products they minimize the interaction of harmful substances considered dangerous
  • The company has increased its reputation and image in the market
  • At the same time, it has achieved a serious competitive advantage both inside and outside the country.
