Intrinsic safety certification is essential for electrical equipment used in hazardous and potentially explosive environments. Certification must be carried out by accredited explosion-proof testing and certification bodies to ensure compliance with international standards such as IECEx, ATEX, UL, CSA, and GB standards.

As a professional third-party certification and technical consulting provider, STS specializes in hazardous area compliance and intrinsic safety (Ex i) certification services for industrial electrical equipment.

We provide comprehensive technical support throughout the entire certification process, including:

• Intrinsic safety circuit evaluation and analysis

• Ex i electrical and structural design support

• Explosion-proof technical drawing preparation

• Certification rectification and compliance guidance

• Ex ia, Ex ib, and Ex ic protection level design

• IECEx and ATEX certification consulting

• Hazardous area compliance assessment

• Technical documentation support for certification applications

Our engineering team has extensive experience in intrinsic safety design, testing coordination, and explosion-proof certification for a wide range of industrial products, including sensors, transmitters, communication devices, control systems, and automation equipment.

With in-depth knowledge of IEC 60079 standards and global hazardous area regulations, STS helps manufacturers improve certification efficiency, reduce project risks, and accelerate market access.
