For manufacturers and labs working with Japanese and broader Asian markets, JIS Z 2371 represents a critical standard for salt spray corrosion testing. This guide breaks down what the standard requires and how it compares to other international benchmarks.
What JIS Z 2371 Covers
This standard specifies methods for conducting salt spray testing to evaluate corrosion resistance of metallic materials and coatings, providing standardized procedures widely referenced across Japanese industrial and automotive sectors.

Key Testing Parameter
Saline Solution Concentration
Similar to other international salt spray standards, JIS Z 2371 specifies a defined saline concentration, typically around 5%, to ensure consistent, comparable corrosion exposure conditions.
Temperature and Humidity Control
The standard defines specific chamber temperature requirements, generally maintained around 35°C, along with humidity conditions necessary to sustain proper fog formation and specimen exposure.
Exposure Duration Guidelines
Testing duration varies based on the specific material and application being evaluated, with the standard providing guidance on appropriate exposure periods for different corrosion resistance claims.
How JIS Z 2371 Compares to Other Standards
While closely related in principle to ASTM B117 and ISO 9227, JIS Z 2371 includes specific procedural details reflecting Japanese industrial testing conventions, making chambers designed with this standard’s requirements in mind particularly valuable for manufacturers targeting Japanese market compliance.

Why Standard-Specific Compliance Matters
Manufacturers exporting products to Japan or working with Japanese industrial partners often need test results specifically compliant with JIS standards, making general salt spray testing insufficient without JIS-specific validation.
Documentation for International Market Access
Maintaining thorough documentation of JIS Z 2371 compliant testing supports smoother market access and partner confidence when working across international supply chains with varying regional standard requirements.
Frequently Asked Questions
Is JIS Z 2371 significantly different from ASTM B117 salt spray testing? The core principles are similar, though JIS Z 2371 includes specific procedural details reflecting Japanese testing conventions that manufacturers targeting that market should follow precisely.
Do chambers need special features to meet JIS Z 2371 requirements? Chambers should be designed or configurable to meet the standard’s specific temperature, concentration, and procedural requirements for compliant testing.
Why would a manufacturer test to JIS standards specifically? Typically because they’re exporting products to Japan or working with Japanese partners who require JIS-compliant test documentation as part of their quality requirements.
Final Thoughts
Understanding JIS Z 2371’s specific requirements helps manufacturers navigate international market access with confidence. Proper compliance with this standard supports smoother partnerships and market entry across Japanese and broader Asian industrial sectors.
