Standard · 2019 ASTM B117-19 — Standard Practice for Operating Salt Spray (Fog) Apparatus ASTM International The reference test method for salt-spray (fog) corrosion testing of coatings, including anodic coatings on aluminium. Specifies test chamber temperature (35 ± 1.1 °C), salt solution concentration (5 ± 1% NaCl), pH (6.5 to 7.2), and spray collection rate (1-2 mL/h per 80 cm² horizontal area). Test duration is specified by the product standard being verified — typical anodize targets are 336 hours for sealed Type II coatings and 500-1000+ hours for sealed hard anodize. The most-cited corrosion-resistance test method globally.

Specifies probe calibration procedure (typically against shim foils traceable to gravimetric reference samples), measurement-area requirements (minimum surface area for valid reading), and reporting conventions. The production-floor instrument of record for anodize thickness QC in plants worldwide.

Standard wheel pairs are CS-10 (mild abrasion) and CS-17 (severe abrasion). Mass loss per 1000 cycles is reported. Properly run hard anodize on 6061 substrate typically shows 1.5-3.5 mg loss per 1000 cycles with CS-17 wheels — a key QC checkpoint for tribological applications.

Test method A is an X-cut for thick coatings; Method B is a cross-hatch (typically 6x6 or 11x11 grid) for thinner coatings. Adhesion is rated on a 0-5 scale (5B = no flaking; 0B = greater than 65% removal). The production-floor QC method of record for powder coat adhesion on aluminium and steel substrates.

The hardest pencil that does NOT mar the coating defines the film hardness rating. Used widely for powder coat QC where Taber abrasion is impractical for production-floor screening. Typical architectural powder coatings rate 2H or harder.

A weighted indenter (typically 1 kg) is dropped from a calibrated height onto a coated panel; the coating is examined for cracking, chipping, or loss of adhesion. Used in QC for automotive, architectural, and industrial powder coat applications where impact resistance is specified.

Specifies indenter load selection (typically 25-100 gf for hard anodize at 30-75 μm thickness), measurement procedure on metallographic cross-sections, and reporting. Hard anodize microhardness is typically reported as HV50 (Vickers at 50 gf load); properly run hard anodize on 6061 alloy typically achieves >400 HV50.

The admittance value correlates inversely with seal quality — a properly sealed coating shows low admittance, an unsealed or poorly sealed coating shows high admittance. Used as a non-destructive seal-quality QC method alongside the dye-stain test (ISO 2143) for sealed anodize batches.
