Introduction to Salt Spray Chamber: It’s Working & Features
To ensure product performance and durability, with quality assurance playing a vital role, corrosion testing has become the most relevant part of the industrial industries. Whether it is automotive parts, electronics, aerospace components, or marine equipment, the only thing that is assured is that your product will face extremely harsh environmental conditions in the time to come.
That’s where Salt Spray Testing comes into play-and at Test Your Product, we specialize in this accelerated corrosion testing method to help you ensure your products are built to last. In this blog, we will introduce you to Salt Spray Chamber, explore how it works, and walk you through the essential features that make it a critical tool: product testing and validation.
What is a Salt Spray Chamber?
The Salt Spray Chamber refers to a laboratory device that is designed for simulating corrosive environments under controlled conditions. It aims to evaluate the corrosion resistance of materials and coatings in significantly less time than natural exposure would require.
The chamber creates a fine, salinized mist (usually a 5% sodium chloride solution) that continuously recirculates around the test samples. Exposure in such a chamber reveals the effective performance of a product or coating under conditions of corrosion, either rusting, flaking, or surface degradation.
Salt spray testing is popular in several industries, including.
- Automotive
- Aerospace
- Marine
- Construction
- Electrical and electronics
- Industrial machinery
In any industry employing metals and coated parts, this test provides priceless insights into the life span of the products and failure risks.
How Does the Salt Spray Chamber Function?
This is a thoroughly corrosive environment; minimized atomization of mist to a salt solution settled on the surface of test specimens in the Salt Spray Chamber. The following explains how such a chamber operates at Test Your Product:
1. Preparation of Salt Solution
Initiating with the usual salt solution preparation of 5 percent sodium chloride (NaCl) dissolved in distilled water or deionized water, having approximately the same salinity as ocean water, hence serves as an excellent medium test for real corrosion conditions.
2. Pre-Start of Chamber.
The test chamber heats up to 35°C (95°F) under international standards, such as ASTM B117 and ISO 9227. It must maintain high humidity by having a proper balance of salt fog suspended in the air to settle evenly onto the specimens.
3. Fog Generation
Compressed air is pushed evenly all over the chamber through atomizers or nozzles as it breaks down the salt solution into fine droplets or fog. It is then directed to the chamber building to create a uniform, repeatable testing atmosphere.
4. Placement of Samples
Test specimens have an angle of mounting fixed within the chamber, commonly inclined 15 to 30 degrees from vertical, to ensure their exposure is uniform. Depending on your product or coating, the test may range from 1-24 hours up to 1,000+ hours.
5. Observation and Evaluation
At recorded intervals or upon completion of the test, selected samples shall be examined for any sign of corrosion.
- Rust formation
- Blistering
- Peeling
- Delamination
- Discoloration
- Cracking
At Test Your Product, these observations are all stored in a high-definition photograph with a well-detailed test log for you, and this becomes part of the final report.
Standard Procedures for Salt Spray Testing
Salt spray testing follows internationally accepted standards, which we adhere to strictly to maintain credibility and consistency:
- ASTM B117: Standard Practice for Operating Salt Spray (Fog) Apparatus.
- ISO 9227: Corrosion tests in artificial atmospheres- Salt spray tests.
- JIS Z 2371: Japanese Industrial Standard for Salt Spray Testing
- DIN 50021: German standard for corrosion testing
These aforementioned standards ensure that the test parameters are consistent enough for results to be comparable across laboratories and industries.
