Salt spray test

塩水噴霧試験は、塩水を噴霧した環境で供試品を曝露し、金属や表面処理の耐食性を短期間で評価する加速腐食試験で、自動車部品や建材など幅広い信頼性確認に用いられます。

中性塩水噴霧試験(NSS)

Neutral salt spray test (NSS)

The neutral salt spray test is an accelerated corrosion test to evaluate the corrosion resistance of materials and surface treated parts. An aqueous solution of sodium chloride (NaCl) is adjusted to neutral (pH 6.5 to 7.2) and sprayed as a mist.

Saltwater Cycle Test (CCT)

Salt Spray Cycling Test is an accelerated corrosion test that repeatedly alternates between salt spray, drying, and humidification processes. This test reproduces corrosion similar to actual environmental conditions in a short period of time and is widely used for durability evaluation of automotive components and surface-treated materials.

塩水複合サイクル試験(CCT)
Special Environment Tests, Salt spray test

Combined saltwater cycle test (CCT)

Combined Salt Spray Cycling Test is an accelerated corrosion test that periodically alternates multiple environmental conditions such as salt spray, drying, humidification, and high-temperature exposure. This test reproduces corrosion mechanisms that closely simulate actual outdoor environments.
