IS 14605 / ISO 8026
Mini Sprinkler Systems
Mini sprinklers and micro sprayers to IS 14605 and ISO 8026 — even coverage at pressures a modest pump can hold, for the crops where drip is too targeted and flood is too wasteful.
Micro-irrigation in the field
Overview
Runs on modest pump heads — typically 1 to 3 kg/cm².
The correct standard for micro and mini sprinklers, aligned to ISO 8026.
Shares HDPE mains with drip zones.
Even coverage, low pressure.
Not every crop wants water at a point. Nurseries, leafy vegetables, germinating beds and close-spaced horticulture all do better with an even wetted area, and mini sprinklers deliver that at pressures a modest pump can hold.
A standards note worth getting right: the micro and mini sprinkler standard is IS 14605, aligned to ISO 8026. IS 12232 is the standard for rotating impact sprinklers used in overhead sprinkler irrigation — a different product. Suppliers citing IS 12232 for a mini sprinkler have the wrong standard on their datasheet.

Choosing between drip and sprinkler
| Consideration | Drip lateral | Mini sprinkler |
|---|---|---|
| Water delivery | To a point at the root zone | Even wetted area across the zone |
| Best suited to | Row crops, orchards, wide spacing | Nurseries, leafy and close-spaced crops |
| Operating pressure | About 1 bar | 1 to 3 kg/cm² |
| Filtration | 75–100 micron (160–200 mesh) | 100 micron |
| Evaporation loss | Lowest | Higher than drip, far lower than flood |
| Germination and establishment | Poor — wets only a point | Good — wets the whole bed |
| Frost and cooling use | Not suitable | Suitable |
Many fields want both, zoned off the same HDPE main. That is the normal design, not a compromise.
Compliance
Standards & testing.
Routine tests are performed on every unit before dispatch. Type tests are certified from CPRI, ERDA or NABL-accredited laboratories on request.
| Standard | Scope |
|---|---|
| IS 14605 | Irrigation equipment — micro sprayers, aligned to ISO 8026 |
| ISO 8026 | Agricultural irrigation equipment — sprayers, general requirements and test methods |
| IS 12232 (Part 1) | Rotating sprinklers — a different product; not the micro sprinkler standard |
| IS 14151 | Polyethylene pipes for sprinkler irrigation systems |
