Quality control

Quality management of manufactured products is carried out on the process based approach to all management activities and is in full compliance with the international standards

The company is certified according to ISO 9001:2015

Product quality management is based on a systematic approach to process control through control points:

• Quality control of purchased materials (including supplier rating)
• Operational control of semi-finished products in the production process 
• Control of technological discipline at the production sites
• Inspection of finished products
• Conducting periodic and acceptance tests of products and materials

 

Parameters measured at all stages of production cycle, from input control to finished products. The measurements are carried out by Plant Laboratory and Nevz Testing Centre.
