EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 12503-3 testing. This standard covers performance and safety requirements for judo mats used in schools, training and competitions. It must comply with the appropriate conditions for the special requirements of international official competitions. Performance and safety values are related to the shock absorption, hardness, anti-slip properties of the sole and the upper friction properties of the surface.
There are methods that rely on bonding or the generation of lateral stresses to secure an insert, but it is not yet clear whether these give the same results as the methods in this section.
The measurement can be used to estimate in-situ strength, determine when post-tensioning can resume, when molds and struts can be removed, winter protection and curing can be terminated, or for comparative testing.
A small metal disc with a centrally fixed rod on one side is inserted into the concrete so that the rod protrudes from the surface of the concrete. The force required to pull the disc out of the concrete is measured.
The loading system must be able to exert a tensile force on the insert as the reaction is transmitted to the concrete surface through the bearing ring. The loading system must ensure that the bearing ring is concentric with the rod and that the load is applied perpendicular to the insert plane.
