ASTM B117 Salt Spray and Salt Fog Testing
Assured Testing Services is capable of providing Salt spray testing per ASTM B117 . The ASTM B117 standard only describes the equipment, the procedure, and the conditions needed to maintain the salt spray fog in the test environment. The ASTM B117 Standard also refers to other salt fog tests which Assured Testing Services maintains on its ISO 17025 scope .
ASTM B117 reference documents are listed here:
ASTM B368 “Test Method for Copper-Accelerate Acid-Salt" (CASS Test)
What is the purpose of ASTM B117 Salt Spray?
The purpose of the ASTM B117 Salt Spray test is to provide a controlled accelerated corrosive environment to evaluate the relative corrosion resistance of the coating, substrate, or part itself. Assured Testing Services has multiple chambers available to run parts and panels of many sizes for the ASTM B117 Salt Spray Test. The number of test specimens, dimensions, and duration of exposure for the test can be specified by the customer.
What services do you offer to precondition the samples?
Assured Testing Services can pre-condition the samples a few different ways to induce points of failures onto the samples. Prior to ASTM B117 Salt Spray we typically scribe the samples IAW ASTM D1654 . We can also expose the samples to gravel bombardment per SAE J400, GMW 14700 and others. These are some of the most common pre-conditions to exposure to ASTM B117.
What kind of samples can you test for ASTM B117?
Typically when testing parts for the ASTM B117, samples are submitted in multiples for validation and comparison purposes. While the parts are in the chamber, they are usually angled between 15 to 30 degrees from vertical orientation. The duration of the test varies depending on the type of coating on the part. Assured Testing has the capability to perform complementary evaluations and preconditioning for the samples submitted, both before and after testing, such as the following:
Masking of portions of samples not to be exposed
ASTM D1654 (Scribe and Evaluations)
ASTM D610 (Degree of Rust)
ASTM D714 (Degree of Paint Blistering)
