Laboratory analysis and testing

Physical and chemical tests ensure that your materials and finished products meet regulatory limits and deliver the expected performance.

This exclusive database allows you to find the main tests to be performed by CTC based on the product, technical criteria, and/or standards.

Water penetration and absorption (WPA)
This test is used to measure the water resistance of upper material. It evaluates both the water penetration time and the quantity potentially absorbed. FootwearMechanical risk / PEEEN ISO 20344 §6.13 / EN ISO 20345 §6.3 Permeability and water vapour coefficient
This test is used to quantify the breathability of an upper material, by evaluating the quantity of water vapour that can potentially pass through it. FootwearMechanical risk / PEEEN ISO 20344 §6.6 / EN ISO 20344 §6.8 / EN ISO 20345 §5.4.6 Tensile properties
This test is used to evaluate the breaking strength and elongation of leather. FootwearMechanical risk / PEEEN ISO 20344 §6.3 / EN ISO 20345 §5.4.4 Tear resistance
The tear strength is an important factor for shoes, parameter. This method is used to evaluate the tear strength of the instep materials. FootwearMechanical risk / PEEEN ISO 20344 §6.3 / EN ISO 20345 §5.4.3 Thickness (class II)
The purpose of this determination is to check leather thickness. FootwearMechanical risk / PEE EN ISO 20344 §6.1 / EN ISO 20345 §5.4.2
