A modern multi-level quality control system compliant with GOST R ISO 9001-2015 standard ensures high quality of products and their compliance with high international standards and requirements of our clients
High quality of fiberglass products is achieved through
- highly skilled workforce
- precise equipment tuning
- incoming control of materials quality (own certified laboratory)
- application of cutting-edge developments in manufacturing
- multi-level quality control system (walkthrough)
- successful testing by leading scientific research institutions of the Russian Federation
The quality control system includes
- inspections of utilized raw materials and finished products for the compliance with modern standards: GOST R 54560-2015, GOST R ISO 10467-2013, GOST 32661-2014, GOST 33123-2014
- testing for compliance with GOST, GOST R, ASTM, BS and AWWA standards in own certified laboratory
Product control types
- visual control
- geometric control
- axial tensile strength measurement control
- ring tensile strength measurement control
- polymerization level control
