Transition from IRIS standard to ISO/TS 22163:2017

At the initiative of the rolling stock manufacturers and UNIFE (Union of the European Railway Industry), the international standard ISO/TS 22163:2017 for the railway sector was created in 2017. Its goal is to achieve a higher level of quality throughout the entire supply chain, or to help manufacturers evaluate their suppliers.

The released certificate ISO/TS 22163:2017 replaces the existing IRIS standard of ZKL Klášterec nad Ohří, a.s. from the year 2016. The successful certification was also supported by ZKL Bearings CZ, a.s. and the research and development company ZKL - Výzkum a vývoj, a. s.


ZKL is the biggest manufacturer of large-scale spherical-roller, special and split bearings in Central Europe.
