Characterization

Obtain product performance information through tests that follow international standards



CeNTI has the right technologies and equipment to characterize product performance during the simulation of use. Various testing services are available, based on international standards, internal test methods or specific protocols developed for a particular product / customer. Knowledge of actual product performance is vital to promoting continuous development, supporting marketing strategies, and demonstrating product differentiation.

Specific test procedures can be designed for products in the following areas:

  • Clothing;
  • Shoe;
  • Car;
  • HVAC systems;
  • Construction Materials;
  • Technical textiles;
  • Among others.

In addition, these technologies can be used to obtain information on product performance, in tests conducted according to various standard procedures, following international standards.
