The European Standard EN 62262 — the equivalent of international standard IEC 62262 (2002) — relates to IK (impact protection) ratings. [1] This is an international numeric classification for the degrees of protection provided by enclosures for electrical equipment against external mechanical impacts.
For impact resistance UL 2218 Class 4 is best. This increases survivability from hailstorms, but the shingles become more susceptible to hail damage with age. [9] Fire resistance: Forest fires and other exterior fires risk roofs catching on fire. Fiberglass shingles have a better, class A, flame spread rating based on UL 790, and ASTM E 108 ...
The term impact resistant is defined as shutters, windows, and doors that have been proven to resist the impact from large windborne debris (defined by the test standards as a 9-pound 2x4 lumber missile striking end on at 34 mph). [2]
