What is the IEC 60068-2-27 standard?

The IEC 60068-2-27 standard, also known as "Environmental testing - Part 2-27: Tests - Test Ea and guidance: Shock" is an internationally recognized standard that provides guidelines for conducting shock tests on various electronic and electrical products. This standard is published by the International Electrotechnical Commission (IEC) and is widely used in industries such as aerospace, automotive, and consumer electronics.

Understanding the purpose of the standard

The main objective of the IEC 60068-2-27 standard is to assess the ability of products to withstand mechanical shocks that they may encounter during transportation, handling, or operation. The standard defines the test methods, equipment requirements, and acceptance criteria to ensure consistent and reliable testing across different manufacturers and laboratories.

Test procedures and parameters

The standard outlines two primary shock tests: test method Ea - half-sine shock and test method Eb - sawtooth waveform shock. Both tests involve subjecting the product under test (P.U.T.) to a series of mechanical shocks of specific magnitudes and durations. These shocks simulate real-world conditions that products may experience during their lifetime. The standard specifies the shock pulse parameters such as peak acceleration, duration, and waveform characteristics.

During the test, various measurements are taken to evaluate the effects of the shocks on the P.U.T. These measurements include physical assessments such as visual inspection for any damages, functional checks, and performance evaluations before and after the shock exposure. Different types of instrumentation like accelerometers, strain gauges, and displacement transducers are used to capture and analyze the shock waveforms and responses.

Benefits and importance

The IEC 60068-2-27 standard provides several benefits to manufacturers, regulators, and consumers. Firstly, it ensures that products are designed and tested to withstand mechanical shocks, thereby reducing the risk of damage or failure during their expected lifespan. Compliance with this standard also allows for fair performance comparisons between different manufacturers and helps in establishing quality benchmarks.

Furthermore, adherence to the standard enables manufacturers to meet regulatory requirements and obtain certifications for their products. It also provides peace of mind to consumers knowing that the products they purchase have been thoroughly tested and are less likely to encounter issues related to mechanical shocks.

In conclusion, the IEC 60068-2-27 standard plays a crucial role in ensuring the reliability and durability of electronics and electrical products. By defining consistent testing methods and parameters, it helps manufacturers deliver high-quality goods while meeting industry and regulatory standards. It serves as a vital reference for product development, manufacturing, and quality control processes, contributing to overall customer satisfaction and safety.
