Questions & Answers
Acrylic sheets are available in the following brands: Limacryl, Setacryl, Altuglas, Perspex and Plexiglas.
International standards for acrylic sheets:
DIN 16957:1985-06 - a standard establishing technical delivery conditions for cast polymethyl methacrylate sheets. This standard specifies the mechanical characteristics, optical properties, dimensions, appearance, acceptance, marking, test methods, thermal characteristics, physical properties, geometric parameters, material, and application range of the sheets.
ASTM D788 is a standard that establishes requirements for cast acrylic sheets produced using polymethyl methacrylate. It establishes uniform technical requirements for cast acrylic sheets, ensuring consistent mechanical and optical properties. This document covers aspects such as weather resistance, dimensions, impact resistance, tolerances, transparency, and surface finish. This document defines the technical characteristics, test methods, and quality parameters of the material for decorative applications, signage, and glazing.
GOST standards for acrylic sheets:
GOST 17622–72 - Technical plexiglass. This standard defines the technical requirements for plexiglass used as a glass substitute in various industries. It regulates physical and mechanical properties, quality standards, dimensions, transparency requirements, testing methods, and grades of plexiglass.
GOST 10667 - Standard defining technical requirements for plexiglass sheets. It is used as a basic document for the manufacture and design of components requiring strength and optical transparency. This document regulates transportation and storage rules, physical and mechanical properties, dimensions, material characteristics, testing methods, and labeling.
