Industrial robot electrical equipment and system: GB/T 37414.1-2019 standard analysis

Introduction：

On June 4, 2019, the latest industrial robotics standard GB/T 37414.1-2019 was released, and is scheduled to be formally implemented on January 1, 2020. In view of the fact that the general EMC test system procurement and installation cycle is more than 4 months, it is necessary to make the equipment procurement plan to meet the test requirements of the new standard in advance.

Ltd. is based in Shenzhen, an EMC EMC test equipment and system providers, the company engaged in EMC technicians with rich qualifications, work experience of up to 10 years or more, built civil, automotive, military, aerospace and other test systems. Now the industrial robot standard update, EUTTEST special for customers to organize the standard analysis, for the majority of customers to carry out new test projects to help.

This article only organizes all the test items, detailed test methods for each item we will provide GB/T 37414.1-2019 test system after home training.
