The RoHS Directive is a regulation that strictly limits the presence of specific hazardous substances in electrical and electronic equipment within the member states of the European Union (EU), due to concerns about their impact on human health and the environment. The products subject to this regulation are electrical and electronic equipment manufactured and sold within the EU member states, including imported goods. The substances whose presence is restricted include four types of heavy metals: lead, mercury, cadmium, and hexavalent chromium, as well as a total of ten substances, which include four flame retardants: polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), and phthalate esters. This regulation has been in effect since July 1, 2006, in all EU member countries. Naito Environmental Management Co., Ltd. has established a system that can provide results within as little as four business days after the samples arrive, using precise analysis with various equipment. We have a wealth of experience in testing related to the RoHS Directive since before its implementation in July 2006, and we have also obtained accreditation for the international standard ISO/IEC 17025. For more details, please contact us or refer to our catalog.

Historically, halogen elements such as chlorine and bromine have been used as flame retardants in electronic and electrical devices and their associated products. When these materials are disposed of or incinerated, dioxins and other harmful substances may be generated depending on the combustion conditions, leading to environmental pollution. Additionally, certain manufacturing processes can negatively impact equipment, causing deterioration. Therefore, international standards such as IEC (International Electrotechnical Commission) 61249-2-21 and the US IPC (Institute for Printed Circuits) 4101B, as well as domestic organizations like the Japan Printed Circuit Association (JPCA), have defined halogen-free standards and are promoting the transition to alternatives. Halogen elements are used in various fields as flame retardants and in applications such as plastic components, cables, printed circuit boards, electronic components, connectors, films, adhesives, and tapes. Naito Environmental Management Co., Ltd. has established a system that allows for precise analysis of chlorine, bromine, fluorine, and iodine, providing results within as little as three business days from the start of analysis to the reporting of results.

The European Chemicals Agency (ECHA) published a candidate list of substances of very high concern (SVHC) under the REACH regulation on October 28, 2008, which included 15 substances. This list will be regularly updated as new substances are identified as SVHCs. Naito Environmental Management Co., Ltd. conducts analyses of phthalate esters and musk xylene in molded products, and also supports the analysis of harmful substances in products and materials in accordance with directives such as RoHS and EN71-Part 3. Please feel free to consult us. For more details, please contact us or refer to our catalog.

Phthalate esters are substances that are primarily used as plasticizers to provide flexibility to plastics, mainly polyvinyl chloride, and are widely used in paints, pigments, adhesives, and other applications due to their low cost and high effectiveness. In recent years, there have been movements to restrict the use of phthalate esters in regulations such as the "European Parliament and Council Directive 2005/84/EC" and the "Food Sanitation Act." Naito Environmental Management Co., Ltd. conducts analyses of phthalate esters in various media, including products/materials, tap water, and environmental water. Please feel free to consult us. For more details, please contact us or refer to our catalog.

In EU countries, regulations on six types of phthalate esters in synthetic resins used in toys have been enforced since January 2007. The regulated substances, standard values, and scope of application are as shown in the table below, and it is necessary to comply with these standards when selling applicable products within EU countries. Naito Environmental Management Co., Ltd. has a proven track record in the analysis of harmful substances in products, as well as various chemical substance analyses. Please feel free to consult us. For more details, please contact us or refer to the catalog.

In recent years, articles discussing the presence of harmful substances in toys have become a topic of interest. The European toy safety standard EN71 Part 3 is a method for testing whether toys contain harmful substances. This standard specifies the testing methods for harmful metals contained in toy materials and components. Naito Environmental Management Co., Ltd. conducts analyses of various types of toys with a short turnaround time (as quick as 3 business days for preliminary results). For more details, please contact us or refer to our catalog.

In the water purification process at facilities such as water treatment plants, standards are established to ensure that the chemicals injected into the water do not contain impurities that exceed specified limits, which could adversely affect the quality of tap water. The substances in question include coagulants like polyaluminum chloride and disinfectants such as sodium hypochlorite, with testing items defined according to the type of chemicals used. Naito Environmental Management Co., Ltd. conducts evaluation tests for water treatment chemicals based on the guidelines of the Ministry of Health, Labour and Welfare and the standards of the Japan Water Works Association, as well as quality tests based on Japanese Industrial Standards and Japan Water Works Association standards. For more details, please contact us or refer to our catalog.

Currently, the RoHS directive, along with regulations like REACH and green procurement, is prompting efforts both internationally and within companies to work towards the goal agreed upon at the 2002 World Summit (WSSD) of "producing and using all chemicals in a way that minimizes their impact on human health and the environment by 2020." Naito Environmental Management Co., Ltd. specializes in environmental and chemical analysis of water, soil, and products, and provides chemical substance management and analysis in line with green procurement. We have developed unique measurement methods and offer contract analysis for "dimethyl fumarate (DMF) in silica gel and resin." Additionally, we conduct tests based on ZEK 01-08 (tests for "polycyclic aromatic hydrocarbons (PAH) for GS mark certification"). For more details, please contact us or refer to our catalog.

Regulations on four phthalate esters (DEHP, BBP, DBP, DIBP) began on July 22, 2019, and it is necessary to confirm the presence or absence of phthalate esters in various products. Our company supports quantitative analysis using a Soxhlet extractor as specified in IEC62321-8, and we have obtained ISO/IEC 17025 (JIS Q 17025) for this analytical method. Additionally, we also support semi-quantitative analysis using thermal extraction devices, which can be utilized for screening analysis. [Features] ■ Compliance with IEC62321-8 for phthalate ester analysis ■ RoHS II compliance ■ Support for semi-quantitative analysis using thermal extraction devices *For more details, please refer to the PDF document or feel free to contact us.

We are currently offering a free booklet summarizing "The Characteristics of PFAS and Regulations in Various Countries"! Please take advantage of it as a resource for new employees' internal training, to understand the flow of regulations for future responses, and to learn about organic fluorinated compounds. Regulations regarding PFAS (per- and polyfluoroalkyl substances) such as PFHxS, PFOS, PFOA, C9-C14 PFCA, and C9-C21 PFCA are expanding both domestically and internationally. Our company offers analysis of a wide range of PFAS (organic fluorinated compounds). For more details, please contact us or visit our website.

We offer analysis of PFAS (per- and polyfluoroalkyl substances) in our products. PFAS refers to perfluoroalkyl and polyfluoroalkyl substances, which is a collective term for over 4,700 types of artificially synthesized organic fluorine compounds. Organic fluorine compounds in products are subject to regulations under the POPs Treaty, REACH regulations, and the Chemical Substances Control Law, and further regulations are expected to be strengthened in the future. To help you understand the regulatory trends as you consider future responses, we have prepared a booklet titled "Characteristics of PFAS and Regulations in Various Countries," which we hope you will find useful.
