Accredited Salt Spray Corrosion Testing Services
At EMC Technologies, our experienced team of engineers perform NATA and A2LA-accredited salt mist test programs to evaluate how materials, coatings and surface finishes withstand corrosive environments.
At our laboratory, we operate an advanced salt spray corrosion test chamber used for product qualification, compliance testing, and accelerated lifecycle evaluation.
The Science of Accelerated Corrosion Testing
Accelerated environmental testing helps determine how materials respond to corrosive conditions more quickly than natural exposure, which can take some time. A standard salt spray test introduces a controlled fog of saline solution into the climatic chamber. This creates a consistently corrosive environment which reveals any weaknesses in protective coatings, plating systems or surface treatments.
Standard Salt Spray (Fog) Test (ASTM B 117)
The ASTM B 117 procedure is the most recognised testing method for corrosion evaluation.
At EMC Technologies, our salt fog test applies a continuous saline aerosol at a controlled temperature and pH level to assess the durability of finishes and coatings. The duration of exposure can vary according to required salt corrosion test performance levels and the intended operating environment.
Our controlled salt spray fog test helps to identify any early signs of rust formation, blistering, structural degradation and coating breakdown.
Compliance and Accreditation
At EMC Technologies, we perform accredited salt mist programs in alignment with international standards such as:
- ASTM B 117
- ISO 9227
- IEC 60068-2-11
- MIL-STD-810 Method 509
We hold NATA accreditation for a broad scope of environmental test methods and are also A2LA recognised, ensuring our reports meet global compliance expectations. Our facility supports both neutral salt spray and advanced corrosion testing methods for industry, defence and commercial product requirements.
At our laboratory, we support the following:
- Full component and coupon evaluation
- Salt spray corrosion test profiles
- Verification of IP certification corrosion related requirements
- Repeatable test cycles using a dedicated salt spray corrosion test chamber

Identifying and Preventing Corrosion Failure
The most common cause of premature product failure is corrosion, therefore testing with an accelerated corrosion test can help to reveal early issues and support design refinement.
Typical failure models identified can include:
- Coating blistering, flaking or softening
- Early rust formation or discolouration
- Loss of adhesion or delamination
- Structural weakening or pitting
- Electrical degradation from ionic contamination
These insights help to support product improvement, warranty management and material validation. At EMC Technologies, our engineers can recommend suitable salt corrosion testing profiles to match operational environments.

FAQs about Salt Spray Corrosion Testing
What is the salt spray method of corrosion testing?
The salt spray method is an accelerated corrosion test where materials are exposed to a controlled saline fog inside a salt spray fog test chamber to assess coating durability.
What is the IEC standard for a salt spray test?
The IEC standard for a salt spray test is IEC 60068-2-11. This outlines the procedure for conducting a salt corrosion test under defined environmental conditions.
Does the ASTM B117 test accurately predict real-world performance?
The salt fog test does not replicate every real-world performance but does provide a highly controlled corrosive environment which highlights coating or material weaknesses.
What is the benefit of using a NATA / A2LA-accredited lab for this test?
The benefit of using an NATA / A2LA-accredited lab is confidence that the corrosion testing process meets strict international standards and procedures defensible results for certification or product validation.
