What is IEC 60068-2-166:2014?

IEC 60068-2-166:2014, also known as the International Electrotechnical Commission Standard 60068-2-166, is a technical standard that specifies the environmental testing requirements for electronic and electrical products. This standard provides guidance on how to test and evaluate the ability of these products to withstand various environmental conditions during storage, transportation, and use.

Scope and Purpose

The scope of IEC 60068-2-166:2014 covers the testing methods necessary to assess the resistance of products to repetitive shock-induced vibrations. These vibrations typically occur during transportation or when the product is subject to mechanical shocks in its operating environment. The purpose of this standard is to ensure that electronic and electrical products can endure such mechanical stress without experiencing performance degradation, failure, or damage.

Test Procedures and Requirements

IEC 60068-2-166:2014 outlines the necessary test procedures and requirements to follow when conducting repetitive shock tests. It describes the test setup, including the equipment and instrumentation required, the specimen preparation, and the specific test conditions. The standard also defines the measurement techniques and criteria for evaluating the test results.

One key aspect covered in the standard is the determination of the resonant frequencies of the specimen under test. Resonant frequencies refer to the natural frequencies at which an object will vibrate most easily. Identifying these frequencies is crucial because if a product's resonant frequency aligns with the frequency of the repetitive shocks it experiences, it may lead to resonance amplification, causing potential damage or failure.

Benefits and Application

IEC 60068-2-166:2014 provides several benefits to manufacturers and users of electronic and electrical products. By complying with this standard, manufacturers can ensure that their products are built to withstand the environmental stresses they may encounter during transportation and operation, thereby increasing product reliability and lifespan. Users, on the other hand, can be confident in the quality and durability of the products they purchase.

This standard is commonly applied in various industries, including aerospace, automotive, telecommunications, and consumer electronics. It helps manufacturers and suppliers in designing robust and reliable products, reducing the risk of performance issues and failures caused by repetitive shocks. Additionally, compliance with international standards like IEC 60068-2-166 can facilitate trade by harmonizing testing requirements and ensuring consistent product performance across different markets.
