BS EN ISO 9261:2010 Agricultural irrigation equipment. Emitters and emitting pipe. Specification and test methods BS EN ISO 9261 is an International Standard which gives mechanical and functional requirements for agricultural irrigation emitters and emitting pipes, and their fittings. It also provides methods for testing conformity with these requirements. BS EN ISO 9261 also specifies the data to be supplied by the manufacturer to permit correct information, installation and operation in the field. BS EN applies to emitters, emitting and dripping (trickling) pipes, hoses, including collapsible hoses (“tapes”) and tubing of which the emitting units form an integral part, to emitters and emitting units with or without pressure regulation and with flow rates not exceeding 24 l/h per outlet (except during flushing), and to fittings dedicated to the connection of emitting pipes, hoses and tubing. It is not applicable to porous pipe (pipe that is porous along its entire length), nor does it cover the performance of pipes as regards clogging.
