Overview

Purpose & Application

The ENV-07 salt spray chamber generates fine atomised saline fog for accelerated corrosion testing of coatings, fasteners and assemblies. Standard 5% NaCl at 35 degC fog matches ASTM B117 NSS conditions; CASS and AASS profiles are supported via temperature and pH control. Complies with ASTM B117, ISO 9227, IS 9000 Part 11, JIS Z2371 and DIN 50021.
