Motion Picture Condition At Risk Assessment Guide
Photochemical Preservation
| Risk Level | Immediate | High | Medium | Low |
|---|---|---|---|---|
| Acidity | 3+ | 2+ | 1+ | ≤1 |
| 16mm Shrinkage | TBD in conjunction with additional condition factors | 1% – 1.3% | .7% – 1% | .7% |
| 35mm Shrinkage | 1.9% + | 1.6% – 1.9% | 1.3% – 1.6% | 1.3% |
| Fading | To be determined in conjunction with Archival Branch | |||
| Emulsion Fogging | Present with evidence of layer separation | Present | ||
| Silvering Out | 100 ft. or longer sections | 50 ft. sections within reel | 25 ft. sections within reel | 10 ft. sections within reel |
| Mold | Large areas with evidence of etching | Large areas with some underlying damage | Large areas easily removed with no underlying damage | Small spots easily removed |
| Brittleness | Present | |||
| Film Base | Nitrate |
Determinations based on factors such as warping, crazing, and other conditions will influence the level of risk in addition to above guidelines.
