DIN Standards Committee Tank Installations

Overview

This standard is applicable to hose assemblies of types 1, 2 and 3 with hoses of silicone rubber for the conveyance of liquid or powdered materials in the pharmaceutical and biotechnical industry. It specifies classification, materials, manufacture, requirements and the testing of hose assemblies as well as their quality monitoring. The hose assemblies are intended for use with materials in the temperature range from -40 °C to +150 °C and for an operating pressure of -0,9 bar (vacuum) to 10 bar. These hose assemblies are not electrically conductive. The danger of static charge is to be considered on a case by case basis. The safe use of hose assemblies is also described in the information document of the Berufsgenossenschaft der chemischen Industrie (German Social Accident Insurance for the Chemical Industry) (BGI 572). Hose assemblies according to this standard are divided into designs A and B (see 3.2). The safe use of hose assemblies is also described in the information documents of the Berufsgenossenschaft der chemischen Industrie (German Social Accident Insurance for the Chemical Industry) (BGI 572).
