Corrosion Test With Flow of Mixed Gas As Per IEC 60068-2-60
How Corrosion Testing with Mixed Gas Helps in Material Durability Assessment
Introduction
- Every year, industries worldwide lose billions due to material degradation caused by corrosion. From electronics and automotive parts to industrial equipment and aerospace components, corrosion can compromise product safety and increase maintenance costs. The Corrosion Test with Flow of Mixed Gas (IEC 60068-2-60) is a vital tool in predicting material durability. By exposing materials to a controlled mixture of corrosive gases, this test helps manufacturers improve product resilience and ensure reliability.
Why is Corrosion Testing Essential?
In real-world environments, materials are constantly exposed to air pollutants, moisture, and temperature changes. These factors contribute to:
⚠️ Rust and Oxidation – Weakens metals, leading to structural failures.
⚠️ Material Degradation – Impacts performance and aesthetics.
⚠️ Electrical Malfunctions – Causes failures in sensitive electronic components.
⚠️ Increased Maintenance Costs – Frequent repairs and replacements drive up operational expenses.
Corrosion testing allows industries to identify weaknesses early and make informed decisions on material selection, coatings, and protective treatments.
How IEC 60068-2-60 Simulates Corrosive Environments
This internationally recognized test standard is used across industries to assess material resistance in polluted environments. The test includes exposure to:
✅ Sulfur dioxide (SO₂) – Simulates acidic industrial emissions.
✅ Hydrogen sulfide (H₂S) – Mimics corrosive gases found in petroleum and chemical industries.
✅ Nitrogen dioxide (NO₂) – Represents vehicle exhaust and urban pollution.
✅ Chlorine (Cl₂) – Common in marine and chemical processing environments.
Step-by-Step Corrosion Testing Process
🔹 Step 1: Sample Preparation – Materials are cleaned and placed in a test chamber.
🔹 Step 2: Gas Exposure – The chamber is filled with a controlled mixture of gases under specific humidity and temperature conditions.
🔹 Step 3: Post-Test Evaluation – After exposure, samples are examined for corrosion signs such as discoloration, pitting, and structural damage.
Key Benefits of Corrosion Testing
✔ Predicts Material Longevity – Helps in material selection and product design.
✔ Ensures Product Reliability – Essential for industries where safety is critical.
✔ Reduces Maintenance Costs – Prevents premature failures and costly repairs.
✔ Ensures Compliance – Meets global standards for quality and safety.
Industries That Rely on This Test
📡 Electronics & Telecommunications – Ensures connectors and circuit boards remain functional in polluted environments.
