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
specifies a laboratory method to determine the of components used in (fittings, valves and ancillaries). Tests are carried out using and produce a characteristic factor that relates pressure loss to flow rate. The standard is intended for manufacturers, test laboratories and specifiers who need repeatable, comparable gas-flow performance data for plastic piping components.
