SCCH - Corrosion Test Chamber

Salt Spray – CASS – Corrodkote – Controlled Humidity

---

. 

📘 General Description

 

The SCCH Chamber is a specialized system designed to perform accelerated corrosion testing under highly controlled conditions. It is engineered for laboratories that require reproducibility, thermal stability, and strict compliance with international testing standards.

It is ideal for evaluating coatings, metals, polymers, automotive components, electronic devices, and aerospace materials by exposing them to severe and repeatable corrosive environments.

 

 

🔍 Types of Tests Performed

 

The SCCH Chamber supports a comprehensive range of standardized testing methods:

 

1. Salt Spray Testing

 

ASTM B117 – The most widely used test for evaluating coatings, surface treatments, and general corrosion resistance.

 

2. CASS Testing (Copper-Accelerated Acetic Acid Salt Spray)

 

ASTM B368 – Accelerated salt spray testing using acetic acid and copper chloride.

Ideal for decorative coatings such as:

• Nickel-Chromium
• Nickel-Chromium-Copper
• Automotive components

 

3. Corrodkote Testing

• Designed for galvanized and decorative coatings.

  Simulates complex atmospheric corrosion conditions to evaluate coating performance and durability

 

4. Humidity and Condensation Testing

• ASTM D1735
• ASTM D2247
• ISO 6270 (International Equivalent)

These tests evaluate resistance to constant humidity and condensation, making them ideal for:

• Paints
• Protective coatings
• Electronic materials and components

 

5. Advanced Corrosion Testing Modes

• • ISO 9227 (NSS, AASS, CASS)
  • ASTM G85 (A1, A2, A3, A4)

 

Includes modified salt spray methods, acetic acid fog, SO₂-containing environments, and other specialized corrosion test procedures.

 

🔧 Chamber Construction and Design

The SCCH Series is engineered to provide durability, ease of maintenance, and maximum stability throughout the testing process.

 

Water-Jacketed Design	Corrosion-Resistant Housing	Seamless Internal Chamber
The chamber is surrounded by a water jacket that maintains highly stable internal temperatures. Benefits include: Excellent temperature uniformity throughout the chamber Reduced influence of external environmental fluctuations Improved test repeatability and accuracy	Depending on the model configuration: Transparent Acrylic Construction – Allows real-time observation of test specimens during operation. Polypropylene (PP) Construction – Provides enhanced chemical resistance for severe corrosion testing environments.	Monolithic construction with no joints that could corrode Long-lasting corrosion-resistant polymer lining Easy cleaning and maintenance Extended service life in aggressive testing environments
