英文名称：Agricultural irrigation equipment — Sprinklers — Part 3: Characterization of distribution and test methods
发布日期：2021-03
标准范围
This document specifies the conditions and methods used for testing and characterizing the water
distribution patterns of irrigation sprinklers.
The term sprinkler is used in this document in a broad generic sense and is meant to cover a wide variety
of products. The specific performance measurements addressed include distribution uniformity, wetted
radius, and water jet trajectory height. This document applies to all irrigation sprinkler classifications
for which those three performance measurements are required to verify the design objectives as
defined by the manufacturer.
This document deals both with indoor and outdoor tests and with radial and full grid tests. It is
organized so as to deal with conditions common to all tests first and then with conditions unique to
indoor testing only and finally with conditions unique to outdoor testing only.
For any given sprinkler, a wide range of nozzle configurations, operating conditions, and adjustments
generate 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.
This document does not address the specific performance testing required for sprinklers intended for
use in frost protection.
This document does not address the topic of drop spectrum measurement and characterization
and the related questions of soil compaction, spray drift, evaporative losses, etc., all of which can be
considerations in the design of sprinkler irrigation systems.
This document is used for evaluating irrigation coverage of sprinklers that are identical and arranged
in a fixed repeating geometric pattern. This document does not apply to moving systems.
This document applies to part-circle sprinklers provided that the testing agency can satisfy questions
of potential anomalies in performance parameters.
NOTE Annex A addresses the procedures for the characterization of sprinkler pattern uniformity. Annex B
addresses testing part-circle sprinklers.
