Standard Salt Spray Chamber
Indeecon ASTM B117 salt spray corrosion chamber for accelerated corrosion testing. ISO 9227 compliant, automotive-grade, competitive pricing.
A salt spray test — or salt fog test — is an accelerated corrosion test used to evaluate the protective performance of coatings, platings, and base materials. A saline solution is atomised inside a sealed chamber, creating a continuous fog environment that simulates years of real-world corrosion exposure in a matter of hours or days. The most widely used standards are ASTM B117 (the original salt spray standard) and ISO 9227, which covers neutral salt spray (NSS), acetic acid salt spray (AASS), and copper-accelerated acetic acid salt spray (CASS) tests.

Frequently Asked Questions
What's the difference between ASTM B117 and other salt spray standards?
ASTM B117 is the U.S. automotive and aerospace standard. ISO 9227 is the international equivalent with minor protocol differences. Both deliver 5% salt spray (1.0–2.0% NaCl) at 35°C. Indeecon's chamber meets both standards, so you validate components for global markets.
How long does a typical test run?
Depends on coating type. Bare steel might show red rust in 24–48 hours; galvanized steel may run 500–1000 hours (weeks). For automotive coatings, 500-hour tests are standard; aerospace requires 1000+ hours. Plan for 2–6 week test cycles.
Can I test multiple parts simultaneously?
Yes. The 250L chamber accommodates 50–100 parts depending on size. Typical arrangement: fasteners on trays, engine components hung vertically, assemblies positioned at 15° angle. Indeecon customizes racks for your specific test plan.
Is NABL certification available?
Yes. Indeecon offers ISO 17025 accreditation support for salt spray testing. If your OEM customer requires third-party corrosion testing, Indeecon's accredited testing service can validate your coatings with formal reports.
What's the environmental impact of salt spray testing?
Salt fog is caustic and requires proper drainage and neutralization. Indeecon's integrated collection system drains salt solution to a waste container. The solution can be neutralized with alkaline rinse and disposed per local environmental regulations. Consult your environmental coordinator for your facility's waste handling protocols.
