DIN (Deutche Industrie Nationale) Standards For Dance Floors

DIN standards are National Germany Industry standards recognized worldwide for a wide variety of uses from computer equipment to dance floors. The standards for dance floors were developed to ensure that dance and aerobic athletes received the greatest degree of safety and performance from a flooring surface when participating in dance and aerobic exercise.

Test
DIN Standard
Description
Shock Absorption
Minimum 53%
Insufficient shock absorption causes activity related injuries to ankle and knee joints. Correct shock absorption reduces fatigue and significantly lowers the risk of injury.
Resilience
Minimum 2.3 mm
Inadequate energy return in a floor causes sore ankles and a surface too "hard" for safe, strenuous activity.
Surface Friction

Minimum 0.5
Maximum 0.7

Rotating and pivoting motions create strain on joints without proper friction coefficients to minimize stress. On a friction scale of .1(ice) to .9(fly paper) .5-.7 is the DIN Standard.
Impact Isolation

W500

Maximum 15%

Without proper impact isolation, participants' movements can interfere with each other, creating the possibility of injury. The standard allows for 15% deflection, 20" from the point of impact.
Surface Stability
Minimum 1500N
Proper foot stability is essential to reducing foot roll-over and other injuries to participants.
