Introduction:

In the era of the Industrial Internet of Things (IIoT) and smart manufacturing, the industrial router serves as the core device connecting industrial equipment to the network, and its reliability, security, and compliance directly affect the stable operation of the entire system. Unlike consumer-grade routers, industrial routers must cope with extreme environments such as high temperatures, high humidity, vibration, and electromagnetic interference, and must therefore pass a series of strict certifications. These certifications not only target specific industry scenarios but also cover regional electronic product standards, ensuring the device's applicability and safety in the global market.

This article will detail the main certification types for industrial routers, the content and scenarios they address, the certification process and testing cycle, and analyze their necessity through case studies from different industries. Concurrently, we will intersperse a comparison of 4G and 5G industrial routers to demonstrate the advantages of 5G in high-performance demanding scenarios, helping readers better understand selection strategies. To enhance readability, this article includes relevant images, video demonstrations, and extended comparison tables. The certification section has been expanded to cover EMC Electromagnetic Compatibility Certification, Safety Certification, Environmental and Reliability Testing, Ingress Protection (IP) Certification, Explosion-Proof Certification (EX), Lightning and Surge Protection, Rail Transit Certification, Automotive Electronics Certification, Power Grid Standards, and Regional Electronic Product Certification.

1. Necessity of Industrial Router Certification

Industrial router certification is the "pass" for products entering the market; it verifies whether the device complies with international or industry standards, covering multiple dimensions such as electromagnetic compatibility (EMC), environmental adaptability, and safety protection. The certification process usually involves laboratory testing, on-site verification, and third-party audits, and the failure rate is often high, but products that pass certification can significantly reduce the risk of failure, extend system life, and avoid legal compliance issues. According to market research, the average failure rate of certified industrial routers in industrial settings can be reduced by more than 30%.

Certifications can be divided into two main categories: General Certifications (basic standards applicable to multiple industries, such as EMC, safety) and Industry-Specific Certifications (for specific application scenarios, such as rail, automotive), as well as Regional Electronic Product Certifications (for global or regional market access). Below, we will analyze these extended certification types one by one, including the certification process and testing cycle (based on international standards and industry practices, the actual cycle varies depending on the laboratory, product complexity, and necessary rectifications).
