Minimal Fogging Potential SAE J1756--Determination of the Fogging Characteristics of Interior Automotive Materials (Photometric Method) Instrument: Hart Scientific 0011 Fog Chamber
Temperature: 100 C Cooling Plate: 21 C Exposure Period: 3 hours Post Conditioning: 1 hour 0.20% 92 UV1 0.15% 99 V9900 Fog Number is defined as 60[degrees] reflectance value of a glass with fogging deposits/ 60 reflectance value of a glass plate without fogging deposits X 100 OBSERVATION: The glass plates were examined and there were no large liquid oily droplets and no crystaline deposits or an oily film.
In other testing, the anti-corrosion primer remained unaffected after thousands of hours in the salt fog chamber
. Cyclic polarization test data also shows that the primer's protection is consistent with that delivered by premium alloys such as Hastelloy.
(2) "The study found that NANO-VCIs exhibited a synergistic effect with an ecologically friendly pigment inhibitor, and the NANO-VCI coating passed salt fog chamber
testing (520 hours with scribing on the metal panels) with less blistering and corrosion than the coating without NANO-VCIs (Figure 2).
The second phase replicated the previous procedure, adding the saline fog chamber
(SFC) intervention to which a saline solution was poured composed of five parts of sodium chloride (NaCl) and 95 parts of type IV demineralized water and prepared according to ASTM B117 standard (chapter 8 --saline solution), under CIC supervision.
FIGURE 3 shows the copper disks coated prior to being placed in the salt fog chamber
. Scuff marks were observed near the center of the Company D 7.2 [micro]m film.
Fluoramics did a test where they took samples of steel plates and placed them in a salt fog chamber
. After just 4 days the piece not coated with HinderRUST looked like it spent the last hundred years buried with the Titanic.
Contrarily, almost immediate failure in the ASTM R117 salt fog chamber
testing typically occurs after material application before little, if any, Mg carbonate has formed.
For this purpose, a fog chamber
that allowed for varying the parameters of fog was developed (Fig.
Two experiments in a fog chamber
(meteorological visibility range of 5-15 m) were run under conditions simulating nighttime fog.
internal components are protected from corrosion by a durable PVC lining and an insulated polypropylene cover prevents heat loss.
All coatings were full military coatings and exposed to neutral salt fog chamber
for 2000 hr.
