GB/T 39402-2020 in English

Analysis of the core content of the standard

GB/T39402-2020 is my country's first national standard specifically for collaborative industrial robots. It has built a complete technical framework from the three dimensions of mechanical safety, electrical design, and human-machine interaction. The standard particularly emphasizes the realization of active protection through the 4.2 Hazard Identification and Risk Assessment process, and requires a systematic evaluation of 17 parameters such as robot load, speed, and contact force.

Key points of safety design innovation

Implementation Suggestions

Enterprises should focus on the following when implementing this standard:

• Phase verification process: Establish a V-type development verification model in accordance with Clause 7.2
• EMC test: The 8 electromagnetic compatibility tests listed in Table 1 must be completed
• Staff training: Operators must receive no less than 16 hours of collaborative safety training

Technology evolution analysis

This standard is innovatively developed based on the GB11291 series:

• Defines the installation posture adaptation function (3.8 terminology) for the first time
• Includes static collision protection (3.7 terminology) as a mandatory requirement
• Supplement the risk assessment method for multi-person collaboration scenarios (Clause 4.2.3)
