This document applies to manually-activated valves only. This document specifies a test method for determining the pressure loss in agricultural irrigation valves under steady-state conditions when water flows through them. The scope and accuracy of the valve performance specifications presented will assist agricultural irrigation system designers in comparing pressure losses through various types of valves. The measurement of pressure losses provides a means for determining the relationship bet...view more

This document specifies construction requirements and test methods for pressurized granulated media filters, hereinafter referred to as media filters, intended for operation in agricultural irrigation systems. It is applicable to both manual cleaning media filters and automatic self-cleaning media filters, used as single unit or in batteries (two or more units working in parallel). This document covers the operation and performance of a media filter, together with all related valves, back flushi...view more

This document specifies general requirements and test methods for volumetric valves able to automatically deliver preset quantities of water. It is applicable to valves actuated by pipeline pressure and flow alone, and which do not need any other, external, source of energy. NOTE Volumetric valves are typically required to operate correctly with different qualities of irrigation water at a variety of flow rates and at temperatures between 5 °C and 50 °C.

ISO 13693-1:2013 specifies the general requirements and test methods for small plastics-bodied valves used for chemigation, intended for operation in irrigation pipe systems which may contain fertilizers and chemicals of the type and concentration used in agriculture.
It is applicable to controllable safety devices (also known as backflow preventers) with a reduced pressure zone (RPZ), intended to prevent backflow by back-siphonage or backpressure of irrigation water into an upstream potable wa...view more

IWA 20:2017 reviews drip irrigation in comparison to major irrigation methods available and practiced today by farmers worldwide. IWA 20:2017 reviews the benefits of drip irrigation, such as increased yield, reduced water consumption, reduced energy consumption, lower environmental impact, reduced contamination of groundwater and surface water, reduced greenhouse gas emissions and reduced labour. IWA 20:2017 also reviews some of the limitations of drip irrigation. IWA 20:2017 does not provide a ...view more

ISO 13460-1:2015 specifies the required properties and test methods for plastics saddles for assembly on polyethylene (hereinafter "PE") pressure pipes used in above-ground and underground irrigation systems conveying water at temperatures not exceeding 50 °C.

ISO 18471:2015 a test method for the verification of filtration grade of filters intended for operation in agricultural irrigation systems. It is intended to be used for verifying the filter manufacturer's declaration about the filtration grade of a specific filter. This test method uses a Clogging Capacity Meter (CCM) device to compare the filtration grade of the filter under test against the filtration grade of a test filtration screen. NOTE This test method may also be used by a filter manufa...view more
