Emitting pipe systems find wide use in drip irrigation systems for delivering water directly to
plant roots through controlled and uniform water distribution. As these systems are quite
important for modern agriculture, manufacturers have to ensure compliance with IS 13488:2008,
which is the Indian Standard for irrigation equipment emitting pipe systems. The BIS
Certification of Emitting Pipe Systems guarantees that the products comply with relevant
requirements regarding material characteristics, sizes, emitter characteristics, uniformity of flow
rate, pressure resistance, hydrostatic strength, and durability. It should be noted that the ISI
Mark for Irrigation Equipment signifies that the product complies with Indian quality standards.
For those manufacturers who require the respective certificate, the certification of emitting pipe
systems is quite necessary in terms of compliance with the relevant BIS QCO and issuance of a
BIS License for Emitting Pipe Systems. The ISI Certification of Irrigation Emitting Pipe Systems
guarantees that the products will serve the needs of farming successfully and efficiently while
fully complying with Indian standards.
