Humidity Cyclic Test As Per IEC 60068-2-38

Humidity Cyclic Testing as per IEC 60068-2-38: Why It Matters for Product Durability

Introduction

What is IEC 60068-2-38?

IEC 60068-2-38 is part of the IEC 60068 series, which defines environmental test procedures for electrical and electronic equipment. This specific test simulates conditions found in humid and tropical climates, where repeated exposure to moisture can lead to material failure over time.

Unlike a constant high-humidity test, IEC 60068-2-38 cycles between temperature and humidity extremes, exposing materials to condensation and drying phases. This provides a more realistic assessment of how a product will perform in real-world conditions.

Why is Humidity Cyclic Testing Essential?

High humidity and repeated exposure to condensation can cause several issues, including:

✅ Corrosion of Metals – Electrical connectors, circuit boards, and mechanical parts can degrade due to oxidation.
✅ Material Softening & Cracking – Polymers, rubbers, and coatings may swell, weaken, or develop cracks.
✅ Short Circuits in Electronics – Moisture can create conductive pathways that lead to electrical failures.
✅ Adhesion Loss – Adhesives and layered materials may delaminate, compromising structural integrity.

By conducting Humidity Cyclic Testing, manufacturers can:

🔹 Detect and resolve design flaws early
🔹 Improve material selection for humid environments
🔹 Meet international quality and reliability standards
🔹 Enhance customer satisfaction with long-lasting products

How Does Humidity Cyclic Testing Work?

The test follows a strict protocol, ensuring accurate and repeatable results:

1️⃣ Humidity & Temperature Cycling – The test chamber exposes materials to fluctuating temperature (25°C to 65°C) and humidity (85-95% RH) levels for multiple cycles.
2️⃣ Condensation Exposure – Some phases encourage condensation buildup, mimicking natural moisture accumulation.
3️⃣ Recovery & Drying Periods – These allow materials to stabilize and help assess long-term durability.
4️⃣ Final Inspection – After the test, samples are analyzed for visual, structural, and electrical failures.

Industries That Benefit from Humidity Cyclic Testing

This test is widely used across multiple industries, including:

🚗 Automotive: Ensuring vehicle electronics, sensors, and coatings withstand humid conditions.
📱 Electronics: Testing printed circuit boards (PCBs), semiconductors, and connectors for moisture resistance.
✈️ Aerospace: Verifying material integrity in high-altitude and tropical environments.
🏭 Manufacturing & Construction: Assessing polymers, adhesives, and coatings for long-term durability.
🔬 Medical Devices: Ensuring product reliability in humid storage and usage conditions.

Final Thoughts

FAQ

1. How long does the test take?

The duration depends on the number of cycles required, typically ranging from 10 to 20 cycles, each lasting several hours or days.

2. What types of failures does this test detect?

It identifies corrosion, delamination, swelling, cracking, short circuits, and reduced mechanical strength in materials and components.

3. How is this different from constant humidity testing?

Unlike constant humidity testing, IEC 60068-2-38 uses cyclic temperature and humidity variations, making it more realistic for real-world applications.

RoHS Testing Lab in Chennai: Ensuring Product Compliance and Environmental Safety

Introduction

In today’s industrial landscape, compliance with environmental regulations is more important than ever. With increasing global restrictions on hazardous substances, RoHS (Restriction of Hazardous Substances) testing has become a crucial requirement for manufacturers, importers, and suppliers of electrical and electronic equipment (EEE).
At Kiyo R&D Center & Laboratory, the leading RoHS testing lab in Chennai, we provide advanced testing solutions to ensure that your products meet global safety and environmental standards.

What is RoHS Testing?

RoHS testing is a process that verifies whether a product complies with the RoHS Directive (2002/95/EC), which restricts the use of certain hazardous substances in electronic and electrical equipment. Originally introduced by the European Union, RoHS compliance is now required in multiple countries, including India.

The RoHS directive restricts 10 hazardous substances, limiting their concentration in products to ensure environmental safety and human health.

Restricted Substances Under RoHS:

The RoHS directive prohibits the use of the following substances in electrical and electronic products beyond specified limits:

1.Lead (Pb) – Used in soldering, batteries, and cables.

2. Mercury (Hg) – Found in switches, thermostats, and lighting products.

3. Cadmium (Cd) – Commonly found in batteries and plastics.

4. Hexavalent Chromium (Cr6⁺) – Used in anti-corrosion coatings.

5. Polybrominated Biphenyls (PBBs) – Flame retardants used in plastics.

6. Polybrominated Diphenyl Ethers (PBDEs) – Found in circuit boards and cables.

7. Bis(2-Ethylhexyl) Phthalate (DEHP) – Used in flexible plastic components.

8. Butyl Benzyl Phthalate (BBP) – Common in adhesives and coatings.

9. Dibutyl Phthalate (DBP) – Found in plastics and electronic devices.

10. Diisobutyl Phthalate (DIBP) – Used in rubber and plastic applications.

RoHS testing ensures that these substances are either completely eliminated or kept within safe limits in electrical and electronic components.

Why is RoHS Testing Important?

1. Regulatory Compliance

Manufacturers selling electrical and electronic equipment must comply with RoHS regulations to avoid legal penalties, product recalls, and loss of market access.

2. Environmental Protection

RoHS compliance ensures that electronic waste does not release hazardous substances into the environment, reducing soil and water contamination.

3. Consumer and Workplace Safety

Products with excessive hazardous substances can cause health issues, including neurological damage, organ failure, and reproductive harm. RoHS compliance helps prevent these risks.

Dielectric Strength Testing in Chennai: Ensuring Electrical Insulation & Safety

Introduction

What is Dielectric Strength?

Dielectric strength refers back to the most voltage an insulating fabric can undergo earlier than it breaks down and lets in electrical cutting-edge to pass via. It is measured in kilovolts according to millimeter (kV/mm) and is a crucial property for materials utilized in electrical and electronic packages.

Key Formula

Dielectric Strength=Breakdown VoltageMaterial ThicknessDielectric Strength = fracBreakdown VoltageMaterial ThicknessDielectric Strength=Material ThicknessBreakdown Voltage

Where:

Breakdown Voltage (V): The voltage at which the fabric fails
Material Thickness (mm): The thickness of the insulating sample

A better dielectric energy shows a better insulating fabric able to withstanding higher voltages without failure.

Why is Dielectric Strength Testing Important?

1. Electrical Safety & Compliance

Prevents electrical screw ups, quick circuits, and breakdowns
