Home About us Quality system

Performing the overhaul works on diesel engines, compressors and reducers in Nuclear Power Plant Krško in the neighboring Republic of Slovenia in the early 90's, TZV GREDELJ applied with full responsibility terms like "quality", "quality insurance" and "non-consistent product".


Already 1994 there was appointed a team for introduction of quality insurance system according to ISO 9001 standard, that consisted of the most responsible managers in the company.


In the same year the first Quality insurance manual TŽV-QA-PR/01/Rev.0 was developed.
In 1999 emerged an up-to-date version of Quality insurance manual QM - NEK / Rev.1 for overhaul works in Nuclear Power Plant Krško according to HRN EN ISO 9002 standard and the appropriate documentation.


By general manager's decision about certification of quality system by the end of 2000, on already established grounds a currently recognizable quality system of the company has grown. The system was confirmed on November 29 th 2000 by SGS ICS certification house.


The confirmation covers designing, development, manufacturing, reconstruction, repair and maintenance of track vehicles, spare parts and assemblies, metal constructions and cranes; testing of brake equipment; repair and maintenance of diesel-electric generators, compressors and gas engines. Quality management system was reconfirmed on January 5 th 2004 by SGS SSC certification house according to ISO 9001: 2000 standard.



It is a very significant event for our company's development and confirmation of our commitment to quality and consistency in maintaining the quality system.


The new certificate is an encouragement and an obligation to persistent joint work in realization of our vision, mission and set goals. We kindly ask all our present and future partners and associates to help us, with their questions, suggestions and advices, in further rising of quality level and successful further and future cooperation.


By small, but safe steps we continue along the quality path in building of modern and successful company, which wants and is able to fulfill the requests and expectations of our customers and users of our products and services.
