TCX footwear models bearing the CE marking are considered items of Personal Protective Equipment (PPE) and their conformity is assessed by a Notified EC certification Body, in accordance with the requirements of the harmonised standard EN13634. Consumers can check the product certification, thanks to a pictogram featured inside every footwear model. This pictogram provides an indication of the level (1 or 2) achieved during the following tests:
X – impact abrasion; X – impact cut test; X – transverse rigidity of footwear
To achieve certification, footwear needs to pass several compulsory laboratory tests in accordance with the harmonised standard EN13634.
IMPACT ABRASION RESISTANCE:
This checks how many seconds it takes to abrade entirely every combination of upper+lining and possible reinforcements in the footwear model in contact with abrasive paper with a grain of 60 revolving at 8 m/s to simulate slipping on the asphalt surface.
– level 1: ≥ 5 seconds;
– level 2: ≥ 12 seconds;
IMPACT CUT RESISTANCE:
This checks the penetration of the blade on every combination of upper+lining and possible reinforcements in the footwear model simulating the upper being cut by a sharp surface (e.g. a guardrail) with a speed of impact 2.8 m/s:
– level 1: ≤ 25 mm;
– level 2: ≤ 15 mm;
TRANSVERSE RIGIDITY OF ENTIRE FOOTWEAR:
This checks the force that needs to be applied onto the finished footwear model to deform it by 20mm simulating a foot being crushed under the vehicle:
– level 1: ≥ 1.0 kN;
– level 2: ≥ 1.5 kN;
ABRASION RESISTANCE OF THE SOLE:
This checks the volume loss of the sole material in 3 mm.
ABRASION MARTINDALE RESISTANCE OF THE LINING:
This checks the wear resistance of the lining since the test simulates the foot rubbing inside the footwear both in dry conditions (25,600 cycles – totaling approximately 8 hours) and wet conditions (12,800 cycles – totaling approximately 4 hours).
DELAMINATION OF THE SOLE FROM THE UPPER:
This checks the bonding force between the sole and the upper and is expressed in N/mm.
WATER PENETRATION RESISTANCE (WR):
This checks whether the footwear remains waterproof after 80 minutes of continuous bending, immersed in a tank with a water level 2 cm above the sole/upper adhesion line.
