The Salt Spray Cabinet Test

The Salt Spray Cabinet Test is to determine the suitability of the paint finishes on our luminaires. We undertake an accelerated corrosion test.

The Salt Spray Cabinet

A solution of distilled water with a 50 gramme per litre (5%) concentration of Sodium Chloride (NaCl) is prepared in a tank. For the test the pH needs to be between 6.5 to 7.2.

Test samples are required to be 1mm ± 0.2mm thick and 150mm x 70mm in size. They are scratched with a scriber until bare metal is exposed and scored.

The test samples are inspected after 240, 480, 720 and 1000 hours of exposure. We look for blisters, creep, rust, pits and cracks.

When the test has been completed (1,000 hours of exposure) we remove the samples from the cabinet, allow them to dry and inspect them one final time. Adhesive tape is then applied to the scratched area and removed, and the paint adhesion results compared to the table in ASTM D3359-09.

Product testing is vital to ensure our luminaires remain up to our standard. To find out on other ways in which we test our luminaires, in our lab click below:
