标准简介：This part of ISO 15886 specifies the conditions and methods used for testing and characterizing the water
distribution patterns of sprinklers intended for agricultural irrigation. It deals both with indoor and outdoor,
radial and full grid tests and is organized to deal first with conditions common to all the tests and then with
those unique to indoor and outdoor testing, respectively.
The term sprinkler is used here in a broad, generic sense, as defined in ISO 15886-1, with the intent of
covering the wide variety of products classified in ISO 15886-1. The specific performance measurements
addressed in this part of ISO 15886 include distribution uniformity, wetted radius and water jet trajectory
height: it is applicable to all irrigation sprinkler classifications for which uniformity of application, wetted radius
and water jet trajectory height evaluation are required for the design objectives, as defined by the
manufacturer. It does not address the specific performance testing required for sprinklers intended for frost
protection use under freezing conditions, nor does it address the topic of drop spectrum measurement and
characterization and the related questions of soil compaction, spray drift, evaporative losses, etc. It is not
applicable to moving systems or sprinklers with a radius of throw of less than 1,0 m.
In order to use this part of ISO 15886 to evaluate irrigation coverage, all sprinklers must be identical and
arranged in a fixed repeating geometric pattern.
