Sports Parquet Floors EN 14904

Today our blog deals with a very delicate subject: Shock absorption and Vertical Deformation of SPORTS FLOORINGS.

Sports Floors Seicom

Our description is based on our experience, requirements set by the International Standards and technical documents issued by authorized Institutes who perform testing procedures.

The GYM PARQUET FLOOR goes through a complex reaction when stressed by a dynamic load.

The interaction components evaluated with tests are the deformation under a load, the shock absorption property and the return of impact energy, for example the amount of energy returned to the player by the parquet floor on which he’s playing.

The shock absorption power of a sports surface is an important safety element.

The reported values are therefore an inevitable compromise between these essential features. The sports floors react differently to different temperature and deformation rates; they become harder at low temperature and softer at higher temperature.

An important element for safety and sport performance is a proper grip between the player’s shoes and the sports floor. An insufficient grip might cause slipperiness on the surface; an excessive grip puts unacceptable stress on joints, ligaments and muscles.

Shock absorption

When tested according the method described by EN 14808, performing at least 4 tests plus a further test every 500 m2 of the area, the average force reduction must be between 25% and 75% and no single test result must differ from the average by more than ±5 units.

Vertical deformation

When tested according the method described by EN 14809, vertical deformation must not be more than 5,0 mm.

All tests must be performed by authorized labs – notified for the execution of EN 14904 tests; values are always listed within test reports, and every company will put the reported values within their own DOP – Declaration of Performance.

Example: Seicom’s TRENTO SOLID comes with DOP, mentioning test report values

sports parquet floor rolling load

Very strong SPORTS PARQUET FLOORS - tested & certified to last.
SEICOM Sports Floors are tested with double load than standard provisions.
The load should be 1.500 N. But SEICOM demands the highest performance.
SEICOM Floors for gyms are certified to withstand a load of 3.000 N.
A further certification proves that there are no joint damages even up to 5.000 N load.

Sports-Parquet-Floors EN 1569

EN 1569 Standard is extremely important: it certifies and guarantees that the surface is not damaged by movable equipment or seating systems.

HEVEA RUBBER WOOD SPORTS PARQUET resists remarkable rolling load, as the test shows: parquet elements, connection between elements, lacquer and sub structure have withstood the load and have been therefore certified by Otto-Graf Institut - Stuttgart University.

PLEASE NOTE: The steel wheel used in the video focuses the rolling load on a single point, just like for movable seating systems or backstop units, even though we have to consider that wheels are usually coated in plastic material (polyethylene) - soft or rigid; wheels also have larger surface to better distribute the load. The steel wheel used for the test is definitely the worst situation that can occur: normally nobody comes with steel wheels on a parquet floor. The test recreates a very stressful situation, in fact we use different wheels and the load is never so concentrated.

It's however good that Seicom's parquet floors are tested for the worst situations though: this is a real quality proof.
In the User's manual about sports parquet floor SEICOM supplies to all Customers, we recommend plastic coated wheels (not rigid) and always a proper rolling load distribution through panels.

The floor for gym made of Hevea Rubber Wood resists a significant rotating load - as shown by the test result. The test puts a significant stress on parquet elements: connection between elements, lacquer and sub-structure withstood this load and therefore have been approved and certified by Otto-Graf Institut - Stuttgart University.
