As tested to HIC (see EN 1177)
critical fall height as tested
Material properly prepared for use in children’s playgrounds
In case of loose fill material, a minimum layer thickness of 100 mm must be added, in order to compensate for reduction of the surface as a result of play
(see 4.2.8.5.1)
No silty or clay particles. Grain size can be identified by use of a sieve test, such as EN 933-1 ( See NOTE 1 in 4.2.8.5.2 )
