Irrigation equipment — Irrigation sprinklers — Part 4: Test methods for durability

Irrigation equipment — Irrigation sprinklers — Part 4: Test methods for durability

This document specifies the conditions and methods for testing the durability of rotating sprinklers for irrigation. The term sprinkler is used here in a broad generic sense and is meant to cover a wide variety of products as classified in ISO 15886-1, which applies to all irrigation sprinkler classifications having both static parts and moving parts during operation, as defined by the manufacturer. For any given sprinkler, a wide range of nozzle configurations, operating conditions, and adjustments generates at least a theoretical need for a correspondingly large number of tests. Testing agencies and manufacturers can use interpolation techniques to reduce the number of actual test runs, provided accuracy standards are still being met.

Irrigation techniques — Remote monitoring and control for irrigation — Part 3: Interoperability

This document establishes requirements for interoperability among systems developed for management and/or control of irrigation facilities. It can be applied under any technological platform and irrigation system, regardless of the water management scheme, with the exception of irrigation mobile machinery, including centre pivots and linear irrigation machines. Due to the dynamic nature of these machines, associated control systems and specific safety requirements, the applicability of exchangeable data for irrigation mechanical move systems was not fully determined at the time of this publication. This document does not define hardware or software requirements for any of the systems to which it applies. It only concerns externally visible interfaces and places no restriction on the underlying implementations. It has been designed to avoid interference with proprietary solutions subjected to intellectual property. From the point of view of the data exchange, and to guarantee interoperability based on the previous premises, this document defines three communication interfaces (interface with management, interface with events and interface with subsystems) and the architecture to which these interfaces apply. Three levels of architecture has been defined to accommodate these interfaces: — The Management Level, where any MIS conforming with this document is located. Out of all available data exchange methods, each MIS only implements those required to execute its functionalities. — The Higher Control Level: coordination. At this level is performed the data integration among RMCS and the access control to it. A software element, called coordination broker, ensures this integration and allows the use of different technologies in its interfaces. — The Lower Control Level: RMCS. These can also be referred to as irrigation subsystems. The RMCS perform the duties of the irrigation entity(s) under its control. A coordination broker can be developed as a product by any of these manufacturers or by an independent developer using the standard specifications for this kind of software.

Agricultural irrigation equipment — Meters for irrigation water

This document specifies the requirements and certification procedures for water meters, irrespective of the design technologies used to meter the actual volume of cold water or heated water flowing through a fully charged closed conduit. These water meters incorporate devices, which indicate the integrated volume. It applies to water meters intended for irrigation use (herein after referred to as water meters), regardless of the water quality used for this purpose. This document also applies to water meters based on electrical or electronic principles and to water meters based on mechanical principles, incorporating electronic devices used to meter the actual volume flow of cold water. It provides metrological requirements for electronic ancillary devices when they are subject to metrological control. NOTE Clean water meters are different from irrigation water meters. This document is based on clean water meters standards but, it is important to develop a specific standard for irrigation water meters indicating their specific requirements.

Agricultural irrigation equipment — Control heads

This document specifies requirements for the components and method of installation of pressurized irrigation system control heads, referred to hereinafter as irrigation control heads, with a nominal size of up to and including 200 mm (nominal size of an irrigation control head or nominal size of a component). This document is applicable only to the above-ground components of irrigation control heads for sprinkler irrigation and micro-irrigation (mini-sprinklers, drip irrigation, etc.). It is applicable to the basic irrigation control head, on which other irrigation control and command components (electrical, electronic and hydraulic) can be assembled, but does not deal with these additional components. This document is not applicable to systems and/or components that can be required to prevent the water from freezing in the irrigation control head, such as dry-barrel hydrants or other types of hydrants. This document does not specify construction or operating requirements for the individual components that make up the irrigation control head. These requirements are specified in the relevant standards for each component.
