BALL REBOUND
Measures the basketball’s response off the sports floor system as compared to the ball’s response off concrete.

SHOCK ABSORPTION
Measures the flooring system’s ability to absorb impact forces normally absorbed by the athlete when landing on a hard surface such as concrete or asphalt.

VERTICAL DEFLECTION
Measures the floor system’s downward movement during the impact of an athlete landing on the surface. This measurement is interdependent with area deflection criteria.

AREA DEFLECTION
Measures the floor system’s ability to contain the deflected area under an athlete’s impact, measured within 20" of impacted area. Also known as Deformation Control when combined with vertical deflection measurements.

ABOUT DIN STANDARDS
DIN is a German standard developed to test products ranging from doorbells to kitchen sinks. Floor surfaces, such as tile, synthetic, carpet and hardwood are included. DIN is analogous to U.S. standards like ASTM and UL. Products can be tested against DIN standards by one of two bodies: The Otto Graph Institute in Germany, or the USSL in the United States. Standards for hardwood floors were introduced in 1991.
