28、lies to type D and type SD hose assemblies with hoses made of elastomers and bonded plastics for the transport of gaseous, vaporous, liquid or powdery substances in the pharmaceutical and the biotechnological industries. It specifies the classification, manufacturing and testing of as well as the ma
29、terials, 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 30 C to +100 C, depending on the medium, and at operating pressures from 0,9 bar (vacuum) to 10 bar (see Tables 2 and 3). F
30、or hoses with a lining made of PTFE and derivatives, temperatures from 30 C to +140 C are permissible. Hose assemblies in accordance with this standard are classified into two designs, A and B (see 3.3). Attention is called to the fact that for certain applications the relevant legal regulations suc
31、h as the Pressure Equipment Directive 2014/68/EU (PED) need to be complied with. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
