Introduction to Hail Impact Testing
Hail is a form of precipitation comprising solid ice. Hail is formed when a thunderstorm updraft lifts a water droplet above the freezing level in the atmosphere causing the water drop to freeze and form ice. Hail can cause potential damage to livestock and people, homes, vehicles, and aircrafts. Hail impact is a destructive environmental phenomena costing millions of dollars every year for damage control.
Hail Impact Testing Procedure
Hail impact testing assesses a material or product’s durability when exposed to hail strike at high velocities and low temperatures. Air canons are used to project both simulated and actual hail to the most accurate results. Projectiles made of metal, stone, or transparent ice are used for testing. Size of hail ranges from 0.5 inch to 2.75 inches in diameter, velocities up to 1111.32 Km per hour and temperatures as low as -20 degree celsius. LASER-equipped systems providing repetitive impacts within a quarter inch of the desired target are used to achieve high accuracy.
Industries and Products
Hail impact testing is extensively utilized in aerospace, automobile, military and defense, heavy machinery, solar energy, building and construction sectors.
Windshields, antennas, vehicle components, aircraft components, solar panels, ground-based commercial equipment, roofing and other building materials are the products that use hail impact testing for their qualification.
Hail Impact Testing Methods
Hail impact testing is a crucial component an environmental testing program done for QA and regulatory purposes. Various test methods are employed for hail impact testing.
ASTM F320: This is the standard test method for hail impact resistance of aerospace transparent enclosures such as windshields, anopy, window, and lens cover. Simulated hailstones consisting of ice balls molded under tightly controlled conditions are used for this test.
ASTM E822: This describes the standard practice for determining resistance of solar collector covers to hail by impact with propelled ice balls. This practice gives a procedure for determining the ability of cover plates for flat-plate solar collectors to withstand impact forces of falling hail. Propelled ice balls are used to simulate falling hailstones. This practice does not cover photovoltaic cells or arrays.
ASTM E1038: This test method is used for determining the ability of photovoltaic modules to withstand impact forces of falling hail. Propelled ice balls are used to simulate falling hailstones. This test method can be used with various sizes of ice balls.
ANSI FM 4473: This is an impact resistance test standard for testing rigid roofing materials by impacting them with freezer ice balls.
