Rolling Load Testing For HuiYa Anti-Static Raised Access Flooring Panels | HuiYa Access Floor Quality Inspection

2019/8/8 9:34:54

Rolling Loads are the most important performance criteria of Access Floor, as Rolling loads have a more damaging effect on the panel than a static load! The raised access floor panel capable of supporting high rolling load enables clean room and data center operators to upgrade their facilities more safely, quickly and cost effectively. To ensure offer the high-quality access floor with excellent rolling load for customers, HuiYa as one of the Top Raised Access Floor Suppliers in China, strictly and comprehensively tests the rolling load of our anti-static raised floor according to the CISCA concentrated load test.

HuiYa Access Floor Rolling Loads Testing

What Is Rolling Load of Access Floor?

Rolling Loads may occur when a vehicle follows a dedicated track i.e. an automated post trolley, or a vehicle that manoeuvres randomly, e.g. a pallettruck. Access Floor Rolling Loads (False Floor Rolling Loads) are defined by the number of passes, size and hardness of the wheel, and the combined weight of the cart and its contents on each wheel.

Why Need To Do Rolling Loads Testing for Access Floor?

Rolling Loads Test Procedures for Access Floor is aim to determine the durability and/or deformation of an access floor system when exposed to commercially anticipated caster traffic using a specific load.

The benefits of Raised Access Floor Rolling Load Testing

  • Being the only standardized method of flooring surface and flooring system performance, thus generating reliable data and results

  • The ability to differentiate your products performance from un-tested competitors' products

  • Endorsed product specification modifications, which potentially leads to retrospective financial savings if specification adjustments are subsequently unsuitable

Rolling Load Testing For HuiYa Anti-static Access Raised Flooring Panels

HuiYa applies CISCA Recommended Test Procedures For Access Floors with panels installed on actual understructure (this more accurately represents an installed access floor system) to determine what is called Design Load or Working Load. This is the load that can be safely applied without experiencing permanent distortion of the panel - In the case of our Anti-static access floor panel from the example above, the Design Load is ≥5560 for 10 passes and ≥4480 for 10000 passes. 

In the below video, we show you the Rolling Load Testing Procedures for HuiYa All-Steel Anti-static Raised Floor, to determine whether our anti-static access raised flooring panels are meeting the required performance levels.

How To Test Access Floor Rolling Loads?

Test equipment and requirements

The experimental equipment for the rolling load of the anti-static raised floor tile shall meet the following requirements:

A) Rolling experimental equipment (equipment travel is greater than 2m, rolling speed 15m/min+5m/min, load range 0N~7000N);

B) Displacement sensor (with peak hold function, accuracy of 3%), can also use X-Y function recorder;

C) Rolling wheel:

  • 1) A rolling wheel, diameter D = 76.2mm, wheel width W = 46.0mm, rolling crown is wrapped with hard rubber or phenolic material, Shore hardness is 90 ± 5.

  • 2) B rolling wheel, used for other models except super heavy duty, diameter D = 152mm, wheel width W = 50.8mm, rolling crown is wrapped with hard rubber or phenolic material, Shore hardness is 80 ± 5.

  • 3) C rolling wheel for super heavy duty, diameter D = 254mm, wheel width W = 102mm, rolling crown is wrapped with hard rubber or phenolic material, Shore hardness is 80 ± 5.

Test Procedure

The rolling load test of the anti-static raised floor panel shall be carried out according to the following experimental procedures:

  • A) Place the three test panels on the rolling test equipment according to the actual installation state, adjust the level and clearance and fix the test panels with the clamp;

  • B) Install the displacement sensor on the bottom surface of the lower plate of the intermediate test plate and in the same axial position as the rolling wheel, so that the displacement sensor is in close contact with the bottom surface of the lower plate of the test plate and is zeroed;

  • C) Add the load to the specified rolling load value, start the rolling test equipment, roll 10 times with a rolling wheel, the maximum deformation of the bottom surface of the lower plate is the deflection of the rolling load, and test the rolling after 1 minute of the rolling wheel is removed from the test plate. Residual deformation of the plate.

According to A), B), C) test method, move the rolling wheel and displacement sensor to the quarter of the floor, and record the deflection and residual deformation of the rolling load.

If the test access floor panel is rolled 10,000 passes according to the load values specified in Table 5, according to the test methods A), B), and C), according to the test requirements, replace it with the corresponding b-roller or c-roller, after rolling 10,000 passes. The deflection of the rolling load was recorded, and the residual deformation of the rolling load was recorded 1 min after the rolling wheel was removed from the test panels.

Using the CISCA concentrated load test, HuiYa Anti-static access floor panels meet the CISCA (Ceiling & Interior Systems and Construction Association) 1,000-pass rolling load test at 450KG (4480N) and 10-pass rolling load test at 550KG (5560N). With the excellent rolling load performance, our anti-static raised floor is perfect choice for computer room, data center, operators and other areas which require high rolling loads.
