What is ISO 24649 - Requirements for manually operated plastics valves about?
ISO 24649 discusses agricultural irrigation equipment. Agricultural irrigation is the agricultural process of applying controlled amounts of water to land to assist in the production of crops, as well as to grow landscape plants and lawns, which may be known as watering.
ISO 24649 specifies the general requirements and test methods for manually operated and hydraulically operated plastics valves intended for use in agricultural irrigation systems. ISO 24649 is applicable to manually operated and hydraulically operated plastics valves (as indicated in Table A.2) of nominal sizes DN 8 (1/4") to DN 200 (8").
Who is ISO 24649 - Requirements for manually operated plastics valves for?
ISO 24649 on the requirements for manually operated plastics valves is useful for:
- Agriculture equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use ISO 24649 - Requirements for manually operated plastics valves?
Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall. Irrigation also has other uses in crop production, including frost protection, suppressing weed growth in grain fields, and preventing soil consolidation. ISO 24649 defines the valves that are intended for installation in irrigation piping networks, using water at temperatures up to 60 °C. They can be fitted with handwheels or add-on automatic control mechanisms. All valve components that come in contact with water are suitable for use with water, fertilizers and chemicals commonly used in irrigation, including treated sewage water.
The body material is opaque. Plastics materials are UV resistant. All parts of the valve are of good workmanship, whole and smooth, and contain no holes, air bubbles, flash, projections, or any other defects that could impair performance or cause injury. All spare parts of valves are made available by the manufacturer within the guarantee period. On request, the manufacturer supplies any available information on the resistance of the valve to corrosive attack by fertilizers and chemicals used in agriculture. Operating conditions, including pressures, are as specified by the manufacturer. Using ISO 24649 you can specify the general requirements and test methods for manually operated and hydraulically operated plastics valves intended for use in agricultural irrigation systems.
