- chemical tests – content of chromium(VI), content of formaldehyde, content of matter soluble in dichloromethane, pH value, difference figure;
- physical tests – thickness, tensile strength, tear load (single and double edge tear), adhesion of finish, colour fastness to rubbing, colour fastness to perspiration, colour fastness to water spotting, flex resistance, abrasion resistance, water resistance (penetration time, water absorption and transmission), water vapour permeability and coefficient.
SERVICES OFFERED OUTSIDE OF THE SCOPE OF ACCREDITATION::
Tannery Laboratory beyond the scope of accreditation performs a series of different chemical and physical tests of finished leathers and semi-finished leathers (e.g. content of total chromium, content of ash, water soluble matter, content of nitrogen and “hide substance”, shrinkage temperature, colour fastness to machine washing, softness, etc.) as well as other materials and auxiliaries. Tannery Laboratory provides advice on the test methods, actual standards, evaluation of the quality of materials and leather goods.
