Auto Technology M Series Size 22 Salt Fog Chamber (C100022-A)
The Auto Technology Series M Size 22 is a durable, lab-proven salt fog chamber engineered for ASTM B117, ISO 9227 and global salt spray standards. Available in standard, high-profile, and low-profile configurations, the Model 22 offers precise temperature control, uniform fog generation, and optional packages for CASS, SO₂, humidity, and advanced corrosion cycles.
Description
The M Series Size 22 Salt Fog Chamber is a durable, production-grade corrosion test chamber designed for laboratories that require repeatable, standards-driven performance with decades-proven reliability. Built in Ohio and used daily in Auto Technology’s own A2LA-accredited corrosion laboratory, the Size 22 delivers uniform salt fog exposure, precise temperature control, and long-term operational stability relied upon by many OEM and Tier-1 programs.
Engineered for ASTM B117 and Global Salt Spray Standards
The Size 22 M Series chamber runs the industry’s core neutral salt fog and salt spray tests with consistent, controlled performance. Its indirect water-jacket heating system, bubble-tower humidification, and uniform chamber airflow support compliance with the following standards:
- ASTM B117
- ISO 9227 (NSS, AASS)
- MIL-STD-810, Method 509.7
- ASTM G85 A1
- Jaguar TPJLR.52.252 / TPJLR.52.253
- MIL-STD-883, Method 1009
- BMW AA-0213
- Nissan MES-M0007 5.22
- EIA 364-31
- JIS 2371 (NSS, AASS)
- Toyota TSH1552G
- EN 13523-8
- JIS 8502 8.2, 8.3, 8.11
- VW 80000 K-06, K-07
- GB/T 10125 (NSS, AASS)
- MIL-STD-202, Method 101
- IEC 60068-2-11
- MIL-STD-331 C3
- ISO 6270-3
- MIL-STD-750, Method 1046.3
- ISO 7253
- ISO 9022-4
- And more
Additional standards, including CASS, copper-accelerated acetic acid, Kesternich SO₂, and high-humidity variants, can be supported through optional packages and chamber customization.
Optional Packages for Advanced Testing
With factory-installed options, the Size 22 can be configured to support:
- ASTM G85 A2, A3, A4
- ASTM B368 (CASS)
- ASTM G85 A5 / JIS H 8502 10.1
- GB/T 10125 CASS
- JIS 2371 CASS
- DIN 50018
- ASTM D2247 (humidity / condensation)
Available Configurations: Standard, High-Profile (H), Low-Profile (L)
Three chamber configurations are available to match sample size requirements and operator ergonomics:
- C100022-A — 31 ft³ (875 L)
- C100022-H — 38 ft³ (1087 L), high-profile for increased vertical clearance
- C100022-L — 24 ft³ (671 L), low-profile for easier loading and access
