Spectral after filter comparison ASTM G155:
| Wavelengh range | Transmission after filter | Benchmark solar | ASTM G155 | Radiation precent after filter |
| (<290nm) | 0.01% | 0~0.15% | 0~0.15% | 0.02% |
| (290~320nm) | 2.85% | 5.80% | 2.6~7.9% | 4.34% |
| (320~360nm) | 23.90% | 40.00% | 28.3~40.0% | 36.46% |
| (360~400nm) | 38.79% | 54.20% | 54.2~67.5% | 59.18% |
| Total UV | 65.54% | 100.00% | 100.00% | 100.00% |
UL 1703 (UL 746C) test results discriminant:
| Physical-property consideration | Material test method |
| Functional support | Tensile strength or Flexural strength (The ultraviolet-exposed side is to be in contact with the two loading points when using the three-point loading method.) |
| Impact resistance | Tensile impact, Izod impact, or Charpy impact |
