ISO 17778:2015 specifies a method for determining the flow rate/pressure drop relationship of components for plastics piping systems when tested using air at 25 mbar.
Abstract
Overview
ISO 17778:2015 defines a standardized laboratory method for determining the of components used in plastics piping systems (fittings, valves and ancillaries). The procedure is carried out using and produces a single characteristic relationship (factor F) that links measured pressure drop and flow rate for a given component size and arrangement. This edition is aligned with EN 12117:1997 and is intended for manufacturers, test laboratories and product specifiers.
