Laboratory
The structure of AMTT Group includes the Central plant laboratory.
The mechanical testing laboratory in the aluminium profile extrusion workshop consistently controls ultimate tensile strength, tensile yield strength and relative elongation of aluminium profiles using MV-30 tensile machine, in accordance with DSTU B V.2.6-3-95 (GOST 22233-93) “Extruded sections of aluminium alloys for enclosure building structures. General specifications”. In addition, mechanical tests of the welded angles of the PVC profile are carried out in accordance with DSTU B V.2.6-15: 2011 “Windows and doors made of polyvinylchlorides. General specifications”.
Besides, the metallography laboratory in the aluminium profile extrusion workshop carries out incoming inspection of ingots for compliance with GOST 23855 “Cylindrical ingots of aluminium alloy AD31. Specifications”, as well as internal inspection of the control samples that represent results of nitrogen hardening of the dies.
laboratory departments: powder painting workshop, mechanical testing, metallography, insulating glass units production workshop.
The laboratory of the insulating glass units workshop performs tests in accordance with DSTU B EN 1279 “Glass in building — Insulating glass units”.
