Rubber and plastics hoses and hose assemblies for use in the pharmaceutical and biotechnological industry with hoses of non-metallic materials — Part 1: Hoses made of PTFE cen:proj:37361

Scope

This standard applies to type D and type SD hose assemblies with hoses made of PTFE and derivatives such as FEP, PFA, PVDF, for the transport of gaseous, vaporous, liquid or powdry substances in the pharmaceutical and the biotechnological industries. It specifies the classification, manufacturing and testing of as well as the materials, requirements and quality surveillance for hose assemblies.
These hose assemblies are intended to be used with the relevant substances at temperatures in the range from −20 °C to +140 °C and at operating pressures from −0.9 bar (vacuum) to 10 bar (see Table 1). These hose assemblies are not electrically conductive. The danger of static charging shall be considered on a case-by-case basis.
NOTE The safe use of hose assemblies is also described in the information brochure (BGI 572) of the Berufsgenossenschaft der chemischen Industrie (German chemical trade association).
Hose assemblies in accordance with this standard are classified into two designs, A and B (see 3.3).
