Tannery Laboratory

Tannery Laboratory has Accreditation Certificate of Testing Laboratory No. AB 033 granted by the Polish Centre for Accreditation on 28.08.1995. This is a confirmation that Tannery Laboratory meets requirements of the PN-EN ISO/IEC 17025:2005 standard "General requirements for the competence of testing and calibration laboratories ", which guarantees the high level of service and the reliability of results obtained.

TESTED MATERIALS AND METHODS:

The Scope of Accreditation of Tannery Laboratory includes physical and chemical tests of different natural leathers (soft, hard, fur, crust), artificial and imitation leathers as well as other materials (textiles, coated fabrics, nonwoven fabrics) intended for production of the protective articles, elements of footwear (upper, vamp and quarter lining, tongue, insole and insock), furniture and automotive upholstery, gloves, clothing, fancy goods and leather haberdashery, etc.

In Tannery Laboratory the tests are carried out according to the standardized methods having the status International (ISO), European (EN) and Polish (PN) standards and they are compatible with these in force now in Member States of European Union. The own procedures established in Tannery Laboratory are also used for the tests. Some examples of the accredited tests that performed the most frequently in Tannery Laboratory are the following:

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. Conducts research related to the scientific activity of Institute of Leather Industry.
