10 Year Limited Warranty
10 (Ten) Year Non-Prorated Material Warranty for Solar Grade Polycarbonate Structured SheetsCrystaLite, Inc. warrants the initial purchaser that, for a period of 10 (ten) years from the date of original purchase, Solar Grade Polycarbonate Structured Sheets will not undergo a loss in light transmission in excess of 6 (six) percent in comparison with the original value when tested in accordance with ASTM D 1003 (95); will not undergo a change in excess of 10 (ten) delta in comparison with the original value when tested in accordance with E 313-73 and will not lose its impact strength as described below.
Determination of loss of impact strength through weathering leading to hail breakage will be carried out by an impact test according to ASTM D 5420-95 and D 5628-95 method F geometry FA (tup diameter 15.86 mm). In the practice of this test the event is considered as a failure when the upper wall of the sheet is penetrated by the tup. The sheet is not up to required standard if the Mean Failure Energy obtained in the test is less than 0.831 Joule. This energy is equal to the energy of an ice ball 20 mm in diameter with a speed of 21 m per second.
