Corrosion & Accelerated Aging Test Chambers

Salt Spray, HAST Pressure-Cooker, and Ozone Aging Test Chambers

Corrosion and material-degradation testing covers a different set of failure modes to temperature/humidity cycling — electrochemical corrosion of metal parts, elastomer and polymer degradation, and moisture ingress under pressure rather than at atmospheric conditions. Each requires a purpose-built chamber rather than a general-purpose environmental chamber run at extended duration.

Sonacme's range covers salt spray (and combined temperature/humidity/salt spray) chambers for corrosion testing to ASTM B117 and ISO 9227, HAST (Highly Accelerated Stress Test) pressure-cooker chambers for accelerated moisture-related failure testing on semiconductor and electronic packages, and ozone aging chambers for evaluating rubber and elastomer degradation under ozone exposure. The salt spray corrosion chamber line spans four volumes from 480L to 8000L.

Frequently Asked Questions

What temperature and humidity range does the salt spray corrosion chamber cover?

Working range spans -70°C to +180°C depending on model and test mode, with humidity control from 20-98%RH — the smaller combined-mode chambers typically run a -20°C to +80°C salt-spray cycle (with fixed test points at +25°C, 0°C and -20°C), while dedicated models extend further for combined thermal cycling work.

What salt solution and spray rate does it use?

A 5% sodium chloride solution as standard, or 5% sodium chloride with 0.26g copper dichloride added per litre for CASS (copper-accelerated) testing, at a spray collection rate of 1.0-2.0ml/80cm²/hour averaged over at least 16 hours.

What sizes are available?

Four chamber volumes — 480L, 1440L, 1800L, and 8000L — with internal dimensions from 1200×850×500mm up to 2000×2000×3200mm.
