Introduction
GB/T 27612 "Agricultural Irrigation Equipment Sprinklers" is intended to consist of 4 parts:
---Part 1: Terminology and classification: The purpose is to give the terminology and classification of sprinklers:
---Part 2: Design and operation technical requirements: The purpose is to give technical requirements for nozzle design and operation:
---Part 3: Water distribution characteristics and test methods: The purpose is to give the key performance indicators of the sprinkler head, the water volume distribution characteristics and its
experiment method:
---Part 4: Durability test methods: The purpose is to provide a test method for the durability of nozzles:
This series of standards completely gives the terms and definitions of nozzles, design and operation technical requirements, water volume distribution characteristics and test methods, resistance to
The durability test method provides a basis for the manufacturing and product upgrading of agricultural irrigation equipment sprinkler heads:
