GOST R 59944-2021 - Composite polymer grid for reinforcement building products and structures. Test methods

Scope: This standard applies to flat and rolled composite polymer mesh (hereinafter referred to as SPC), manufactured with diameters from 2 to 4 mm, with rods located in two mutually perpendicular directions, and establishes test methods for determining the following technical indicators of SPC: 　——appearance; 　——geometric parameters of rods and dimensions; 　——content of continuous reinforcing filler; 　——tensile strength of rods; 　——modulus of elasticity when stretching the rods; 　——reduction in tensile strength of rods after exposure to an alkaline environment; 　——destructive force during shear of rod connections; 　——glass transition temperature of the polymer composite; 　——destruction of the connection of rods due to impact
