Cass Cum Salt Spray Chamber

Model : CASS-1000H

A Salt Spray Chamber, also known as a Cass Cum Salt Spray Chamber, is an advanced corrosion testing instrument designed to assess the performance and durability of surface coatings, metallic materials, and component finishes under accelerated corrosive conditions. This chamber replicates a highly saline, fog-like environment similar to what materials experience in coastal or industrial atmospheres.

What is Salt Spray Chamber – Cass Cum Salt Spray Chamber

A Salt Spray Chamber, also known as a Cass Cum Salt Spray Chamber, is a precision-engineered corrosion testing equipment designed to evaluate the resistance of coatings, paints, and surface treatments against a saline or corrosive environment. This testing method, commonly known as Salt Spray Test (SST) or Salt Fog Test, helps determine how long a material or coating can withstand harsh environmental conditions before showing signs of rust or corrosion.

The Cass Cum Salt Spray Chamber is an advanced version of the traditional salt spray tester, following ASTM B117, ISO 9227, and JIS standards. It’s widely used in industries like automotive, aerospace, electronics, and metal finishing to ensure high-quality and durable surface protection.

How Does the Cass Cum Salt Spray Chamber Work

The Cass Cum Salt Spray Chamber operates by atomizing a saltwater solution (typically 5% NaCl) through a fine mist nozzle inside a controlled testing chamber. Test samples are placed inside the chamber at a specific angle, allowing the mist to uniformly settle on their surfaces.

The chamber maintains controlled temperature, humidity, and spray conditions, simulating long-term exposure to corrosive marine or industrial atmospheres within a short period. The CASS (Copper Accelerated Acetic Acid Salt Spray) variant adds copper chloride and acetic acid to the saline solution, intensifying the corrosive effect for faster and more aggressive testing — ideal for evaluating decorative coatings such as nickel-chrome plating.

By observing changes like rust formation, blistering, or coating breakdown, engineers can accurately assess a material’s corrosion resistance and quality performance.

FAQs

What is a Cass Cum Salt Spray Chamber?

A Cass Cum Salt Spray Chamber is a corrosion testing machine that simulates a salty, humid environment to evaluate the corrosion resistance of metals, coatings, and surface finishes. It uses a copper-accelerated acetic acid salt spray (CASS) solution for faster and more aggressive testing compared to standard salt spray tests.

What standards does the Cass Cum Salt Spray Chamber comply with?

The chamber is designed according to major international standards, including:

ASTM B117 – Standard Practice for Salt Spray Testing
ASTM G85 Annex A1 – CASS Test Method
ISO 9227 – Corrosion Tests in Artificial Atmospheres
JIS Z 2371 – Salt Spray Testing Methods

These ensure reliable and globally accepted test results.

How does the Cass Cum Salt Spray Chamber work?

The chamber generates a fine mist of saltwater mixed with acetic acid and copper chloride, which continuously settles on the sample surfaces. By maintaining a constant temperature and humidity, the chamber accelerates corrosion. Test results are then analyzed for rusting, pitting, or coating degradation to measure durability.

What materials can be tested in a Cass Cum Salt Spray Chamber?

This chamber is suitable for a wide range of materials and coatings, including:

Electroplated metals (nickel, chrome, zinc, copper)
Painted or powder-coated surfaces
