SEFA Testing Method | |
Rating | Description |
0 | No detectable change in surface. |
1 | Slight change in color or gloss, viewable from only one angle. “Oily stain” remains after cleaning with soft dish soap solution. |
2 | Sever stain viewable from all angles. Evidence of swelling due to absorption of reagent after 24 hours. Sunken appearance due to extraction of reagent |
3 | Obvious degradation of the material. |
Physical Stability | This was a 4 hour immersion test in reagent. Pre and post measurements used to quantify % change of foam sample. |
