BS EN ISO 04641-2016 pdf download – Rubber hoses and hose assemblies for water suction and discharge — Specification (ISO 4641:2016) 1 Scope This document specifies the minimum requirements for textile-reinforced, smooth-bore rubber water-suction and discharge hoses and hose assemblies. Three types of hoses and hose assemblies are specified according to their operating duty requirements,i.e.their ambient and water temperature ranges: -ambient temperatures:-25°C to +70 C; – water temperatures during operation: 0 °C to +70 °℃. 2Normative references The following documents are referred to in the text in such a way that some or all of their contentconstitutes requirements of this document.
