What is IEC 60068-2-27 shock resistance?

Introduction

IEC 60068-2-27 is an international standard that provides a method for testing the resistance of electronic and electrical equipment to shock. It specifically focuses on the ability of equipment to withstand mechanical forces that may occur during transportation, installation, or operation.

The Purpose of IEC 60068-2-27

The main purpose of IEC 60068-2-27 is to ensure that electronic and electrical equipment can function properly and safely, even when subjected to various shocks and vibrations. The standard sets out specific test procedures that manufacturers must follow to assess their products' resistance to mechanical stress.

The goal is to verify whether the equipment can withstand shock levels that may occur during its lifecycle without suffering any significant damage or malfunction. In essence, the standard helps to ensure that the equipment remains operational and reliable under real-world conditions.

Testing Procedures

The testing procedures outlined in IEC 60068-2-27 involve subjecting the equipment to a series of shocks and vibrations of varying intensity. These shocks are applied in different directions, including both axial and non-axial orientations, to replicate possible forces that could act upon the equipment during transit or operation.

The standard defines various shock levels classified by the peak acceleration reached during testing, expressed in units of g (acceleration due to gravity). The shocks are applied using specialized machines capable of delivering precise, controlled forces to the equipment.

Throughout the testing process, the equipment's performance and functionality are continuously monitored. After each shock event, the equipment is inspected for any damage, deterioration, or functional impairment. Additionally, functional tests may be performed after the entire series of shocks to assess the equipment's overall performance.

Compliance and Certification

Once the testing is complete, manufacturers can evaluate whether their products meet the criteria specified in IEC 60068-2-27. Compliance with this standard is an indication that the equipment has demonstrated a certain level of shock resistance.

Manufacturers often seek certification from authorized testing laboratories to validate their products' compliance with the standard. Such certifications provide assurance to customers that the equipment meets recognized industry requirements and can withstand shocks within defined limits.

In conclusion, IEC 60068-2-27 plays a crucial role in ensuring the quality, reliability, and durability of electronic and electrical equipment. By subjecting equipment to rigorous shock tests, manufacturers can gain insights into potential vulnerabilities and design robust products that can withstand the rigors of real-world environments.
