Why Salt Spray Test Defines Product Durability

Corrosion is one of the most common causes of product degradation, especially for metals, coatings, and electronic components. The Salt Spray Test is a critical method used to evaluate the corrosion resistance of materials and coatings under accelerated conditions. Standards such as ASTM B117 and ISO 9227 define the parameters for this test, ensuring consistent and comparable results. LIB Industry provides a comprehensive solution with advanced Salt Fog Chambers designed for reliable, repeatable, and standard-compliant corrosion testing.

1. Sample Preparation:

Clean fastener surfaces and place on V-shaped sample racks, ensuring uniform exposure for each piece.

2. Test Setup:

- Temperature: 35°C ± 1°C

- Salt solution: 5% NaCl, pH 6.5–7.2

- Humidity: 95–98% RH

3. Spray Cycle and Duration:

- Continuous spray mode

- Duration: 720–1000 hours

- Internal air circulation system maintains temperature ±2°C and humidity +2% / -3%

4. Observation and Rating:

- Inspect every 24–48 hours, recording rust grade and coating delamination

- LIB’s precise atomization and control system ensures stable and reliable testing

Result: Throughout the test, fog density and temperature remain stable, producing uniform corrosion across all samples. Customer feedback shows reduced failure rate and increased testing efficiency, providing reliable data for quality control and production decisions.

FAQ – Common Questions about Salt Spray Testing

Q1: What standards can LIB Industry Salt Fog Chamber meet?

A1: ASTM B117, ISO 9227, GB/T 2423.17, and JIS Z 2371.

Q2: How does LIB prevent salt spray leakage?
A2: Chambers are made of one-piece, corrosion-resistant fiberglass and feature a water-sealed trough that effectively contains salt spray.

Q3: Do these salt spray chambers have automatic water refill?
A3: Yes. Automatic inlets monitor water usage and refill as needed to maintain continuous operation.

Q4: What water is used for humidity in CCT?
A4: Water supplied via the automatic inlet generates humidity, with flow dynamically adjusted to keep levels consistent.

Q5: How should waste liquid from SO₂ tests be handled?
A5: Weakly acidic, water-soluble liquid is collected through the drainage outlet and treated per environmental safety regulations.

Q6: What maintenance is required?
A6: Regularly clean nozzles and chamber, replace saturator water, and remove dust from electrical components to ensure safe, reliable operation.
