4].
| Method of testing | Flexural strength (MPa) | Modulus of elasticity (MPa) |
| Preliminary parameters | 69,4 | 9253 |
| Aging by the influence of constant temperature (65 ± 3)°C and a relative humidity close to 100% for 28 days | 50,7 | 8360 |
| Aging for 3 × 1000 hours, in 40°C and 50% relative humidity, UV 550 W/m2, water pouring every 100 minutes for 18 minutes | 65,0 | 9543 |
| Cycles of freezing and thawing, 100 cycles | 70,2 | 8833 |
