With the global environmental protection requirements gradually increasing, ROHS (Restriction of the Use of Certain Hazardous Substances Directive) standards have become an important basis for countries to establish regulations for the manufacturing of electronic products and electrical equipment. 2024, the ROHS standard was updated again, establishing more stringent regulations on hazardous substances in electronic products, involving 10 elements of the restrictions, thus prompting the global market to pay more attention to the awareness of environmental protection.
The changes in the new ROHS 2024 standard center on stronger controls on certain hazardous substances and higher requirements for companies in production, testing and reporting. To help companies and consumers understand these changes, we will provide an in-depth introduction to the 10 elements of the ROHS 2024 standard that not only have a direct impact on the safety of electronic products, but also play a critical role in environmental and health protection.
1. Lead (Pb)
Lead has long been recognized as one of the most hazardous heavy metals, posing a serious threat to the human nervous system, immune system, and other aspects of health, and the restrictions on the use of lead in the ROHS 2024 standard remain strict. Although lead can still be used under certain circumstances, its use must not exceed 0.1%, which not only makes manufacturers more careful in material selection, but also promotes the research and development of alternative materials.
2. Mercury (Hg)
Mercury is another heavy metal that is harmful to the environment and the human body, especially to water, air and soil. Mercury can cause damage to the central nervous system, which is especially harmful to pregnant women and fetuses, and the ROHS standard sets the mercury limit at 0.1% and provides specific requirements for the recycling and disposal of mercury-containing electronic products, reinforcing the environmental protection measures in the recycling of electronic products.
3. Hexavalent chromium (Cr6)
Hexavalent chromium is a potent carcinogen, which is potentially harmful to the skin, respiratory tract and internal organs of the human body, etc. ROHS 2024 further restricts the use of hexavalent chromium by requiring that the content of hexavalent chromium in electronic products shall not exceed 0.11 TP3T, which will not only help to reduce the emission of hazardous substances during the manufacturing process, but also help to protect the safety of the consumers.
4. Polybrominated biphenyls (PBB)
Polybrominated biphenyls (PBB) are chemically stable flame retardants, but are also considered to be a persistent hazard to humans and the environment.The toxicity and bioaccumulation of PBB has made it an important target of the ROHS 2024 standard, which requires that electronic products contain no more than 0.1% of PBB, a change that will help reduce the flow of hazardous substances into the environment. This change helps to minimize the flow of hazardous substances into the environment.
5. Polybrominated diphenyl ethers (PBDEs)
Polybrominated diphenyl ethers (PBDEs) are another common flame retardant with similar hazards to PBB, causing damage to the endocrine, nervous and reproductive systems of the human body, and the ROHS 2024 standard also imposes a strict restriction on the content of PBDEs in electronic products, requiring that the content of PBDEs in electronic products should not exceed 0.11 TP3T. With the implementation of this requirement, manufacturers will have to increase the development and application of alternative flame retardants.
6. Progenic substances (PAH)
Polycyclic Aromatic Hydrocarbons (PAH) are a group of chemicals that are extremely hazardous to the environment and human health, and long-term exposure to PAH can increase the risk of cancer.ROHS 2024 standard puts forward more specific limit requirements on the content of PAH, and imposes more stringent control on the concentration of PAH in electronic equipment, which prompts enterprises to pay more attention to the selection of environmentally friendly materials in the product design and production process.
7. Cadmium (Cd)
Cadmium is a highly toxic heavy metal that poses a significant threat to human health, especially the kidneys, bones and respiratory system, and the ROHS 2024 standard still maintains a high level of restriction on the use of cadmium, requiring that cadmium content should not exceed 0.011 TP3 T. This standard will further promote the use of cadmium-free materials, and will place higher requirements on the environmentally friendly design of electronic products and the selection of materials.
8. Dichlorobenzene (PCB)
PCB is an environmental pollutant with strong bioaccumulative properties, causing serious impacts on aquatic organisms, animals and plants. rohs standard 2024 imposes more stringent limits on PCBs, requiring that the content of PCBs in electronic equipment should not exceed 0.1%. this change helps to reduce the risk of PCBs in discarded electronic products reaching the soil and water supply.
9. Trivalent chromium (Cr3)
Trivalent chromium is less harmful to humans than hexavalent chromium, but still has a certain degree of toxicity, and the ROHS 2024 standard regulates trivalent chromium, requiring that the content of trivalent chromium in electronic products should not exceed 0.11 TP3T, which will help to minimize contamination of trivalent chromium in manufacturing processes and further promote the application of environmentally friendly technologies.
10. Polyvinyl chloride (PVC)
Polyvinyl chloride (PVC) is a common plastic material, but its production process may release toxic gases, causing pollution to the environment. rohs 2024 standard for electronic products containing PVC has put forward more stringent requirements, which will force enterprises to increase the development and application of biodegradable plastics to reduce the harm to the environment.
With the full implementation of the ROHS 2024 standard, the manufacture and design of electronic products worldwide is facing higher environmental challenges, but at the same time providing more opportunities for innovation and upgrading. These stringent restrictions are not only reflected in the control of the 10 hazardous elements, but also in the higher demands placed on manufacturers in terms of production, recycling and environmental compliance.
1. Technological innovation and application of alternative materials
The ROHS 2024 standard requires substantial restrictions on the use of traditional hazardous substances, which has prompted enterprises to increase research and development of environmentally friendly materials. New materials such as new lead-free solder, mercury-free displays and non-toxic flame retardants are gradually replacing traditional hazardous substances, and have become the main development direction of the electronic product manufacturing industry. This not only helps to protect the environment, but also makes the use of electronic products safer and enhances the overall market competitiveness of the products.
2. corporate compliance and testing requirements
The ROHS 2024 standard also strengthens the compliance requirements for companies by requiring more stringent testing and inspection during the design and production process. Manufacturers are required to conduct detailed compositional analyses of their products to ensure that every component meets the standard. This not only improves product quality, but also promotes technological advancement in environmental protection in the electronics industry.
3. Environmental Responsibility for Recycling and Disposal
With the upgrading of ROHS standards, companies are taking on more environmental responsibility in the life cycle of their products. The recycling and disposal of electronic products has become an important issue. According to ROHS 2024, enterprises must ensure that waste electronic products will not cause pollution to the environment during the recycling process. This has also prompted companies to strengthen environmental planning at the product design stage and establish closer cooperation with recycling organizations to jointly promote the rational treatment of electronic waste.
4. Global markets affecting businesses
The update of the ROHS standards does not only affect the EU market, but also manufacturers of electronic products around the world must comply with these regulations. Many countries and regions have adopted ROHS as the compliance standard for imported electronic products, which requires companies to follow the corresponding environmental regulations regardless of the market in which they sell their products. Therefore, understanding the impact of the new ROHS 2024 standard on global trade is an important task that every company must not overlook.
5. Conclusion: ROHS 2024, towards a greener future
With the implementation of the ROHS 2024 standard, the environmental requirements for electronic products have become more stringent, but they also provide companies with opportunities for innovation. By continuously exploring new materials and technologies, and actively addressing the challenges of the ROHS standard, we will welcome greener and healthier electronic products. While meeting environmental requirements, companies will be able to enhance the competitiveness of their products and gain a market advantage. For consumers, this means they can use safer, non-toxic electronic products and enjoy a healthier, more environmentally friendly lifestyle.
In this era of increasing environmental awareness, the ROHS 2024 standard will undoubtedly become an important indicator to lead the electronics industry towards sustainable development.
