Measures for environmental hazardous materials

Adjustment for hazardous materials (EU-RoHS and CHINA-RoHS)

Today, the disruption of the global environment has been taken up as a serious issue for human beings and a mission for its safeguard has become all the important. We, at KOA, started active management of chemical substances included in our products, and complied with EU RoHS Directive in July of 2006 and Management Electronic Products(China RoHS) in March of 2007. “Regulation concerning the Registration, Evaluation, Authorization and Restriction of Chemicals” was enforced in June of 2007 as the new chemical regulation in Europe. Social demand to environmental statutes is increasing like this, and we are actively addressing to the compliance with these laws and regulations.
In addition to the compliance, we are also advancing various activities such as halogen-free specifications to reduce hazardous substances and certification as a laboratory according to JIS Q 17025.

(1) EU-RoHS

The restriction of Hazardous Substances Directive (2002/95/EC), (RoHS), became effective on July 1 of 2006 requiring the usage of restriction of following six hazardous substances in the manufacture of electrical and electronic equipment placed on the market. This directive was amended on June 8 of 2011, to Recast Directive 2011/65/EU of the European Parliament and of the Council. The original directive was expired as of January 2, 2013 and replaced by a new directive (2011/65/EU) on the following day. Later, Annex II (Restricted Substances List) was amended by Commission Delegated Directive (2015/863/EU) and four phthalates were added to the restricted substances list.
The followings are restricted substances and maximum concentration:

  • Lead (0.1wt%)
  • Mercury (0.1wt%)
  • Cadmium (0.01wt%)
  • Hexavalent Chromium (0.1wt%)
  • Polybrominated biphenyls [PBBs] (0.1wt%)
  • Polybrominated diphenyl ethers [PBDEs] (0.1wt%)
  • Bis (2-ethylhexyl) phthalate [DEHP] (0.1wt%)
  • Butyl benzyl phthalate [BBP] (0.1wt%)
  • Dibutyl phthalate [DBP] (0.1wt%)
  • Diisobutyl phthalate [DIBP] (0.1wt%)

    • ＊ The percentage in parentheses show the maximum concentration value in the homogeneous material. The restriction of applications in the annex in the directive is exempted. KOA’s products applicable with this exemption to EU RoHS2 are as follows (as of July 2022):

    • Copper alloy containing up to 4% lead by weight
    • Electrical and electronic components containing lead in a glass or ceramic other than dielectric ceramic in capacitors, e.g. piezoelectronic devices, or in a glass or ceramic matrix compound.

    To meet EU-RoHS, you need to choose lead (Pb) free material for termination surface material when our product has both type designation, leaded and lead free.

(2) Revised China RoHS(Management Methods for the Restriction of the Use of Hazardous Substances in Electrical and Electronic Products)

China RoHS became effective in March 2007 and the Revised China RoHS was promulgated in January 2016 and became effective on July 1, 2016. The compliance management catalog (target products) and exemption list for the second step (inclusion restriction) were released in March 2018 and we must comply with requirements of the “evaluation system” from November 1, 2019.
For each product, we disclose the content information of the six hazardous substances directed by China RoHS. Please contact our sales representatives for details.

We use the codes of terminal surface material to identify products with Pb-free terminal and products with Pb terminal. See our typical type designations (*1).

REACH

“Regulation concerning the Registration, Evaluation, Authorization and Restriction of Chemicals” (REACH) has been enforced on June 1 of 2007 in EU area. This regulation is aiming at safety evaluation and risk management of chemical substances, which are required to register according to the amount if used in businesses. Substance of Very High Concern (SVHC) must be registered if it is included in article. The European Waste Framework Directive has also been revised. As a result, products placed on the EU market after January 2021 are required to register SCIP data if the concentration of SVHC exceeds 0.1wt% in order to also provide information on environmentally hazardous substances to waste disposal companies. Information communication on such substances is also required throughout the supply chain using information communication tools such as chemSHERPA.
