Frequently Asked Questions
What is the difference between ASTM B117 and ASTM G85 testing?
ASTM B117 creates a continuous neutral salt-fog exposure. ASTM G85 contains five modified salt-spray annexes with acidified chemistry, cyclic phases, synthetic sea salt, sulfur dioxide, or dilute-electrolyte Prohesion conditions. The governing product specification or test objective determines which method applies.
Can Auto Technology run every ASTM G85 annex?
Yes. Auto Technology offers laboratory testing for ASTM G85 Annexes A1 through A5. Different profiles require different chamber capabilities, chemistry, gas dosing, temperature ranges, and transition performance.
What is the difference between salt spray and cyclic corrosion testing?
Continuous salt spray maintains a fog exposure. Cyclic methods introduce defined changes in wetting, drying, humidity, temperature, or solution application. Select the method required by the governing specification or best aligned with the investigation objective.
Do you support industry and OEM corrosion standards?
Yes. The laboratory supports ASTM, ISO, SAE, DIN, OEM, military, and project-specific corrosion, environmental, coatings, and materials methods, including Ford TM 00.00-L-467 and legacy CETP 00.00-L-467 testing and VDA 233-102 and ISO 11997-3 testing. Submit the exact designation and revision for capability and scope confirmation.
Can you prepare test panels and apply coatings?
Yes. ATC supports substrate preparation, blasting, custom panel fabrication, coating application, masking, edge protection, scribing, and related specimen-preparation steps.
What testing is useful for electronics or connectors?
Mixed flowing gas is often appropriate for low-concentration atmospheric pollutant corrosion, while salt mist, single-gas exposure, cyclic salt, humidity, condensation, or combined environments may apply depending on the materials, service environment, and governing specification. See Auto Technology’s electronics corrosion test chamber guide for the different exposure types, standards, and chamber configurations used for electronics and connector testing.
Do you offer analytical or failure-analysis support?
Yes. Available work includes FTIR, gas chromatography, microscopy, compositional analysis, elemental profiling, targeted metals screening, comparative investigation, and failure-analysis-driven testing.
