GB/T 2423.7-2018 "Environmental testing - Part 2: Test methods, Test Ec: Impact caused by rough handling (mainly for equipment-type samples) " standard specifies the method of rough handling impact testing on equipment-type samples. The standard defines the terms and conditions of Impact, and describes in detail the test equipment, implementation steps, and result evaluation requirements. It is mainly used to simulate the rough operating conditions that equipment may encounter during actual operation, and to evaluate its Impact Resistance and Structural Stability to ensure the Reliability and safety of equipment in similar environments.
