ISM is directly embedded in the structure of our joint stock company. The organizational rules firmly set out the duties and powers of the departments so that the requirements for quality assurance, environmental protection and occupational safety are guaranteed.

Conformity assessment of our products is governed by Act 22/1997 Coll. "On technical requirements for products" (as amended), Government Decree No. 163/2002 Coll. (as amended) and Regulation (EU) No 305/2011 of the European Parliament and of the Council laying down technical requirements for construction products. When assessing the conformity of sleepers, we follow the European Directive for the interoperability of the rail system 2008/57 / EC and the relevant technical specifications (TSIs). For specified construction products, the MLSA issues a declaration of conformity or a declaration of properties.
