IEC 60068 Standard Overview for Environmental Reliability Testing

Introduction

IEC 60068 is one of the most widely accepted international standards for environmental reliability testing of electrical, electronic and mechanical components. It defines uniform test methods, conditions and acceptance criteria to evaluate how products withstand different environmental stresses during storage, transportation and end-use.

Many manufacturers and test laboratories require IEC 60068 compliance for product certification. Our full line of environmental test chambers is engineered to run multiple environmental test items defined within IEC 60068 series.

What does IEC 60068 cover?

The standard is divided into multiple parts, covering different environmental stimuli:

1. Temperature tests (High temperature / Low temperature) Verify product performance under continuous high or low temperature exposure. High temperature test is used for thermal aging, heat resistance assessment.
2. Temperature cycling / thermal shock Evaluate material expansion and contraction stress caused by rapid temperature change.
3. Humidity & temperature-humidity combined test Check reliability under moist and hot working conditions.
4. Vibration, shock, drop test Mechanical stress testing for transit and operation.

 For our environmental test chamber product line, we mainly focus on IEC 60068-2-1 / IEC 60068-2-2 (Dry heat test) — the most common thermal reliability test         requested by our industrial customers.

IEC 60068-2-2: Dry Heat Test (High Temperature Test)

This section specifies the procedure for exposing samples to a constant high temperature environment inside a test chamber.

• Purpose: Assess if materials, electronics or metal parts can keep function after long-time high-temperature aging.
• Typical test samples: Electronic modules, plastic parts, metal workpieces, coated components.
• Required equipment: A high temperature chamber with stable temperature control and good temperature uniformity.

Our high temperature test chambers meet the equipment requirements for IEC 60068 dry heat test. They adopt forced hot air circulation, PID precision temperature control and stainless steel inner chamber, to maintain stable thermal environment for reliability aging test.

Why choose IEC 60068 testing?

• Unify test procedures between suppliers and buyers globally
• Reduce product failure risk after mass production
• Support product certification for European and international markets
• Compare reliability data of different batches or material versions

How our Environmental Test Chambers Support IEC 60068 Testing

Our full range of environmental test chambers can be used for:

✅ IEC 60068-2-2 dry heat aging test

✅ IEC 60068 temperature & humidity combined test

✅ IEC 60068 thermal shock test

✅ Material thermal resistance screening

✅ Pre-conditioning of samples before other reliability tests

Our chamber series features precise temperature adjustment, uniform temperature distribution, and easy operation, suitable for factory in-house labs and third-party test institutions.

IEC 60068 provides a global baseline for environmental reliability evaluation. Thermal and temperature-humidity testing are core parts of this standard.

If you need equipment to run IEC 60068 environmental reliability tests, our environmental test chambers can provide stable, repeatable test conditions for your product reliability verification.
