Wpływ EN 13813 na normy o skręcie podłogowym w przemyśle

Wprowadzenie do EN 13813

Developed by they European Committee for Standardization (CEN), it defines a unified condiwork for specifying, testing, and classifying screed materials used in industrial, commerciaule, and heaid -duty flooring applications.

Scope andd Application

EN 13813 is relevant to a wide range of industrial environments where loor performance is critial. These include warehours, factorie, logistics centers, automativy plants, appeeutical facilities, food processing units, andd cold stores. In each case, the screed must with stand specific mechanical, thermal, and chemical stressors.

Te standard also andexes thee interface between thee screed and thee substrate, including ding adhesion requirements for bonded screeds, and movement joint configurations for unbonded andd floating screeds. By covering both materiale conperformenties andd system- level performance, EN 13813 ensures the final lour assemble meets the expectod servisie life and safety standards.

Key Requirements of EN 13813

EN 13813 provides a chemical resistance classification based on thee drop tect or inmersion tett methods descripbed in EN 13892-6.
