EN 16821:2017 (E) 3 European foreword This document (EN 16821:2017) has been prepared by Technical Committee CEN/TC 218 “Rubber and plastic hoses and hose assemblies”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2017, and conflicting national standards shall be withdrawn at the latest by December 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 16821:2017 (E) 4 1 Scope This European Standard applies to type 1 to type 3 hose assemblies with hoses made of silicone rubber for the transport of liquid or powdery 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
« v r °C1) to +150
¹C and at operating pressures from
« rá { 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. Hose assemblies in accordance with this standard are classified into two designs, A and B (see 3.2). Attention is called to the fact that for certain applications the relevant legal regulations such as the Pressure Equipment Directive
