Salt spray testing is a critical method for assessing how materials and coatings withstand harsh saline environments. By simulating long-term exposure to salt, humidity, and acidic conditions, this testing ensures that metals, coatings, plastics, and composite materials maintain durability and reliability across industrial, automotive, and decorative applications.
LIB's Salt Spray Testing Cabinets provide accelerated corrosion testing with repeatable, traceable results, helping manufacturers and R&D teams confidently evaluate product performance. LIB chambers operate in strict compliance with international standards, including ASTM B117, ASTM G85 (SS, ASS, CASS), and ISO 9227 (NSS, AASS, CASS), ensuring that test data is accurate, consistent, and globally recognized.

Reasons for Developing Salt Spray Testing Cabinets and Their Benefits
Salt spray testing cabinets were designed to reliably copy salty, corrosive environments and see how materials react. In real life, metals, coatings, plastics, and composites face salty air, humidity, acid rain, and pollution that speed up rust and damage. Testing outdoors takes too long and results are unpredictable, so it's hard for companies to judge performance consistently.
By recreating these conditions in a lab, salt spray tests turn months or years of exposure into just hours or days. This fast feedback helps teams improve coatings, test protective layers, and confirm that new alloys or composites resist corrosion. It also supports quality control by catching bubbling, cracking, or peeling before products reach customers.
These tests follow global standards like ASTM B117, ASTM G85, and ISO 9227, which set clear rules for temperature, pH, and salt levels. Using a chamber that meets these standards gives manufacturers trusted, comparable results they can show to customers and regulators.
Salt spray testing helps avoid costly failures and warranty claims by spotting weak points early. Whether for cars, planes, electronics, or industrial parts, verifying corrosion resistance in a fast, controlled way helps products last longer, perform better, and protect a company's reputation.
Key Benefits:
Accelerated Aging: 5% NaCl at 35 ± 2 °C for NSS tests simulates months or years of outdoor exposure within hours.
Traceable Results: Deposition rates of 1–2 mL/80 cm²·h ensure reproducible testing.
Versatile Applications: Supports decorative coatings, zinc die-cast components, automotive parts, electrical enclosures, and specialty materials.
Quality Assurance: Detects weaknesses such as blistering, cracking, or scribe creep, reducing warranty claims and improving product reliability.
