DIN 26055-3:2010-09

This standard is applicable for hose assemblies of types D and SD with elastomeric and plastic hoses for the conveyance of gaseous, vaporous, liquid or powdered materials in the pharmaceutical and biotechnological industry. It specifies classification, materials, manufacture, requirements and the testing of hose assemblies as well as their quality monitoring. The hose assemblies are for use with materials in the temperature range from -30 °C to +100 °C depending on the medium and for an operating pressure of -0,9 bar (vacuum) to 10 bar. For hoses with an inner liner made of PTFE and derivatives, temperatures from -30 °C to +140 °C are permitted. 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 3.3). It should be noted that, for certain applications, the appropriate legal provisions, for instance the Wasserhaushaltsgesetz (WHG) (Water Resources Management Act), the Druckgeräterichtlinie (Pressure Equipment Directive) 97/23/EC (DGL) or the Arzneimittelgesetz (German Drug Law) are to be complied to. This standard has been prepared by Working Committee NA 104-02-01 AA "Schlauchleitungen" ("Hose assemblies") of the Tank Installations Standards Committee (NA Tank).
