GB30228 Ground Impact Attenuation Tester for Sports Field

1、 Equipment Overview:

HICThe ground impact attenuation performance tester for sports fields is used to simulate and detect the impact performance of the ground surface on the head after a fall, and can accurately measure the impact on the head of the sports fieldHICMeasure the values and automatically calculate the strict height for safe falls on sports fields and children's playgrounds. The product does not require external force to move the heavy hammer, and the instrument can move flexibly as a whole and automatically display the detection results.

2、 Meet the standards:

1）SatisfyBS EN 1177-2008(Impact damping amusement park pavement).In the standard for determining critical drop heightAnnex ATest requirements (impact testing device)

2）GB30228-2013Safety performance requirements and test methods for ground impact attenuation of sports venues)Standard No5.1.2Test requirements
