The physical testing aims at evaluating performance, comfort, safety, and quality characteristics of footwear, leather and leather goods.

 


Examples of possible tests are below:
       Footwear:
             Heel attachment, impact, fatigue
             Crocking of upper and lining
             Slip resistance
             Flexion
             Abrasion
             Water resistance of the upper
       Leather goods:
             Crocking
             Adhesion of finishing
             Stitch tear strength of leather
       Leather:
             Color fastness to perspiration
             Thickness
             Tear strength resistance (Trouser and Double)

 

The chemical analyses ensure the innocuousness of products that will come in contact with skin.

 


A small sample of our capabilities is below:
       Formaldehydes
       PH value
       Heavy Metal content
       Chromium VI content in leather
       PCP/TeCP (Pentachlorophenol & Tetrachlorophenol)
       Azodyes
       Allergenic and Carcinogenic dyes
       ...
