Ladder Test - DR.LADDER

Ladder Test

We attach great importance to the quality and safety of ladders, and conduct internal tests and cooperate with third-party certification agencies to ensure that our products are safe and durable. Take a look at how are ladders tested to meet or exceed the requirements of the new standard.

The Base Slip Test

It requires the ladder to be no longer than 4m.

In order to pass the test, the ladder feet must not move more than 40mm.

Lateral Deflection

The maximum allowable deflection shall not exceed the calculation based on the length of the ladder.

Bend Test

The maximum permissible deflection must not exceed a calculation based on the span distance of the ladder.

Strength Test

After removal of the test load the ladder, stabilisers and their connections shall remain functional with no fracture or visible cracks.

Torsion Test

The difference between the deformation of the two stiles should not exceed 0.07 times of the external width of the ladder section.

Durability Test

The ladder must be able to support the load without showing signs of rupture.

Opening the Restraints and Hinge Test

The ladder must not show any deformation of the hinge joints or restraint devices. There must be no cracks, indentations or other visible damage and the ladder must remain in full working order.

Torsion Test

The distance between the ladder and its original position must not exceed 25mm whilst the test load is applied.
