SALT SPRAY AND CYCLIC CORROSION TESTING
Corrosion can affect the appearance, functionality, and long-term durability of automotive materials and components.
imat provides professional salt spray testing and cyclic corrosion testing to evaluate metals, coatings, assemblies, and finished components under controlled environmental conditions.
We perform corrosion testing according to international standards and automotive specifications, including:
ASTM B117 | ISO 9227 | ISO 11997-1 | PV 1210 | GMW14872 | BMW AA-0324
A2LA-accredited laboratory network
More than 30 years of automotive testing expertise.
SALT SPRAY TESTING
During salt spray testing, specimens are exposed to a controlled saline atmosphere inside a corrosion chamber.
The test is suitable for:
- Coated and uncoated metals
- Painted and plated surfaces
- Fasteners and brackets
- Connectors and housings
- Automotive interior and exterior components
- Complete assemblies
Typical evaluations include red rust, white corrosion, blistering, delamination, discoloration, coating breakdown, and corrosion creepage from a scribe.
CYCLIC CORROSION TESTING
Real-world corrosion exposure is rarely constant. Components are typically subjected to alternating periods of salt, humidity, drying, and temperature changes.
Cyclic corrosion testing reproduces these changing environmental conditions through defined and repeatable test cycles.
This method is especially suitable for:
- Complete components and assemblies
- Mixed-material constructions
- Coated systems
- Joints, edges, and fasteners
- Customer-specific automotive validation programs

WHEN TRANSPARENCY
BECOMES A QUESTION OF TRUST
FOGGING is more than just an optical phenomenon - it is a decisive quality factor for vehicle interiors, air quality and customer satisfaction. At imat, we test materials and components for volatile components that can be deposited on cooler glass surfaces in hot weather. This ensures that invisible emissions do not become visible complaints.
WHY THIS IS IMPORTANT
- OEM specifications require low-emission materials.
- Panes with fogging scatter incident light so that the view outside becomes blurred. Critical in the dark and in incident light. Fogging not only affects the appearance, but also health, odor and well-being in the vehicle interior.
WHAT SETS US APART
- Global standards: Tests according to CVTC 54004, D45 1727, DIN 75201, GMW 3235, ISO 6452, PV 3015, Q/CC JT146, Q/JLY J7110341B, RNES-B-00070, SAE J 1756, SMTC 5 400 010, TSM 0503 G, VCS 1027,2719

OUR STRENGTH: PEOPLE WHO LIVE PRECISION
Our specialists know that even the smallest amounts of substances can have a big impact.In our accredited laboratories, they analyze materials, components and systems for emissions and fogging effects - using state-of-the-art measurement technology and the experience gained from over 35 years of testing expertise.
WHEN THE SMALL
MAKES THE DIFFERENCE
MICROCHAMBER TESTING is the perfect tool for evaluating emissions from individual materials or components during the development process - fast, standardized and meaningful. At imat, we use microchambers to determine VOC, SVOC and aldehyde emissions under controlled conditions. This allows us to ensure material purity, compliance and brand quality before a vehicle is even built.
WHY THIS IS IMPORTANT
- OEMs demand early approval for low-emission materials.
- Shorter development times demand fast, reproducible results.
WHAT SETS US APART
- Accredited procedures: Tests according to CS-13398, FLTM BZ 151-01, GMW 17082, TP-0000912, TPJLR 52.104

BAG TESTING: OUR PROTECTIVE SHIELD
AGAINST INVISIBLE EMISSIONS
BAG TESTING is a key procedure for analysing volatile substances (VOC, SVOC, formaldehyde, odorous substances) before they can affect the air quality in the vehicle. At imat, we test materials, components or complete parts in specially conditioned test bags. This enables us to identify emissions at an early stage.
WHY THIS IS IMPORTANT
- Strict OEM specifications regulate the interior air quality of modern vehicles.
- New materials and recyclates pose new challenges because they also have to meet the existing requirements with the existing tests
WHAT SETS US APART
- We test a range of standards: For example BAS 483, CS-A0229, CVTC 54072, D10 0003, DWG 0094Z, ES X83252E, FLTM BZ 108-01, GMW 17914-A, MS 300-55, NES M0402-01, NES M0402-02, Q/CC SY248, Q/CC SY349, Q/JLY J7110274B, RTS 1745, SES N 2403 and many more
