Neutral Salt Spray
Widely used neutral pH exposure for benchmarking protective coatings.
Overview
Accelerated durability screening for coated parts
Salt spray tests expose specimens to a controlled saline mist to accelerate corrosion and evaluate coating performance and process quality. Ideal for decorative and protective finishes on steel, zinc alloys, aluminium alloys, and plastics.
ISO/IEC 17025:2017 Accredited laboratory with automated, multi-condition exposure
capability.
Methods
Test methods we run
Acetic Acid Salt Spray
Introduces acetic acid for a more aggressive environment and faster attack.
Copper-Accelerated ASS
Adds copper ions—preferred for decorative Cu/Ni/Cr coatings on metals.
Modified Salt Spray
Custom exposures and conditioning based on service environment.
Capabilities
What our lab offers
Six salt spray chambers
Automated, parallel exposures with precisely regulated parameters (PLC/SCADA).
Component exposure up to 2.6 m
Accommodates large panels and assemblies; 5+ dedicated chambers.
24×7, 365-day operation
Over 495,000 exposure hours and counting.
CASS corrosivity calibration
Calibration performed for each exposure period; quarterly chamber corrosivity checks.
Inspection & evidence
Photographic documentation every 8/24/48 hours; graphical exposure logs shared.
Periodic sample cards
We share sample cards & periodic updates during long exposures.
Reporting
What you receive
- Exposure conditions and chamber controls (time, temperature, solution, pH).
- Timed photographic evidence and visual grading notes.
- Summary of coating performance and pass/fail against your criteria.
Applications
Where salt spray testing is used
Cu/Ni/Cr decorative coatings
Evaluate layered plating integrity on consumer & automotive components.
Steel, Zn alloys, Al alloys, plastics
