Salt Spray Chamber

A Salt Spray Chamber creates a controlled sodium chloride fog environment for comparing the corrosion resistance of metals, coatings, plating and painted surfaces. It helps quality-control teams identify coating defects and compare material or process performance under repeatable laboratory conditions. Salt spray exposure is primarily a comparative test and should not be directly converted into an exact number of outdoor service years.

Applications
Pacorr Salt Spray Chamber is used to test corrosion resistance in:

• Painted metal panels
• Powder-coated components
• Zinc-plated and galvanized parts
• Chrome-plated products
• Automotive brackets, fasteners and underbody parts
• Marine fittings and coastal-use components
• Electrical enclosures and switchgear parts
• Aluminium and steel components
• Hinges, locks, nuts, bolts, screws and hardware items
• Coating samples used in R&D and quality laboratories

The chamber is suitable for automotive, electroplating, paint, marine, electrical, aerospace, fastener and independent testing laboratories.

Benefits of Using Salt Spray Chamber

• Product rejection reduction
• Warranty claims reduction
• Supplier comparison
• Production consistency
• Export-quality requirements

How to Use Salt Spray Chamber

1. Prepare the salt solution as per the selected test standard.
2. Check and adjust the pH value of the solution.
3. Fill the solution reservoir with the prepared salt solution.
4. Clean the test specimens before placing them inside the chamber.
5. Place samples on the rack at the correct angle with proper spacing.
6. Set the chamber temperature, air pressure and test duration.
7. Start the test and monitor fog collection during operation.
8. Record temperature, pH, fog collection and test time at fixed intervals.
9. After completion, remove the samples carefully and inspect the surface.
10. Clean the chamber, reservoir, nozzle and accessories after the test cycle.

Actual test compliance depends on correct solution preparation, pH control, chamber temperature, air pressure, fog collection rate, sample placement, test duration and documentation followed by the laboratory.

FAQs

Q1. Does salt spray testing show the exact service life of a product?
No. A salt spray test does not determine the exact number of years a product will perform in real outdoor conditions. It is an accelerated laboratory method used to compare the corrosion resistance of materials, coatings, plating and surface treatments under controlled conditions. Results should be assessed against the applicable test standard, customer specification or predefined acceptance criteria.

Q2. What is the standard test temperature for a Salt Spray Chamber?
For a Neutral Salt Spray test, the chamber temperature is commonly maintained at 35°C ± 2°C. The required temperature may differ for other corrosion-test methods. Operators should set the chamber according to the selected standard and product-testing requirement.

Q3. What pH range is required for salt spray testing?
For Neutral Salt Spray testing, the pH of the collected salt solution is normally maintained between 6.5 and 7.2. The solution should be prepared carefully, and its pH should be checked before the test and monitored during extended exposure periods to maintain consistent conditions.

Q4. Why is FRP used in a Salt Spray Chamber?
FRP, or Fibre-Reinforced Plastic, is highly resistant to salt fog, moisture and corrosive test conditions. Its use helps protect the chamber body from corrosion and reduces the possibility of contamination inside the test area. FRP construction also supports longer equipment life and easier maintenance.

Q5. Which Salt Spray Chamber capacities are available?
Pacorr offers Salt Spray Chambers in 250-litre, 450-litre and 1000-litre capacities. The correct chamber size should be selected according to specimen dimensions, testing volume, sample quantity and available laboratory space. Sufficient spacing should be maintained between specimens to allow uniform fog circulation.

Q6. Is an air compressor included with the Salt Spray Chamber?
The Salt Spray Chamber requires a suitable external compressed-air supply, typically around 7 CFM. The air compressor is not part of the standard supply unless specifically included in the quotation. Customers should confirm the compressor capacity, air quality and connection requirements before installation.

Q7. How is the fog-collection rate measured?
Fog is collected through funnels placed inside the test chamber. The collected solution passes into graduated measuring cylinders, allowing the operator to measure and record the fallout rate. A typical collection rate is 1–2 ml per 80 cm² per hour, subject to the applicable test standard and operating conditions.

Q8. What is the price of a Salt Spray Chamber?
The price of a Salt Spray Chamber depends on its capacity, controller configuration, monitoring features, optional accessories and customisation requirements. Models with 250-litre, 450-litre and 1000-litre capacities may have different prices. Share the specimen size, required standard and preferred features with Pacorr to receive an accurate quotation.
