BS ISO 15886-3:2012+A1:2016 specifies the conditions and methods used for testing and characterizing the water distribution patterns of irrigation sprinklers. The term sprinkler is used in this standard in a broad generic sense and is meant to cover a wide variety of products as classified by ISO 15886-1. The specific performance measurements addressed include distribution uniformity, wetted radius, and water jet trajectory height.This standard applies to all irrigation sprinkler classifications for which these three performance measurements are required to verify the design objectives as defined by the manufacturer.This part of ISO 15886 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 may use interpolation techniques to reduce the number of actual test runs provided accuracy standards are still being met.This part of ISO 15886 does not address the specific performance testing required for sprinklers intended for use in frost protection.This part of ISO 15886 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.To apply this part of ISO 15886 for evaluating i rrigation c overage, a ll s prinklers must be identical a nd arranged in a fixed repeating geometric pattern. This part of the standard does not apply to moving systems.This part of ISO 15886 applies to part-circle sprinklers provided that the testing agency can satisfy questions of potential anomalies in performance parameters.Annex A addresses the procedures for the characterization of sprinkler pattern uniformity. Annex B addresses testing part-circle sprinklers.Cross References:ISO 9644:2008Incorporates the following:Amendment, October 2016. Amends and replaces BS ISO 15886-3:2012
