Solenoid valves are subject to various international standards that define their design, performance, and testing criteria. The specific standards may vary based on the type of solenoid valve (e.g., general purpose, process valve, automotive solenoid valve). Here are some commonly referenced standards for solenoid valves:
1. **ISO 5599:** This standard specifies pneumatic fluid power components, including solenoid valves. ISO 5599 is often used for pneumatic control valves, including directional control valves, and it provides guidelines for design, testing, and performance.
2. **ISO 15407-1 and ISO 15407-2:** These standards apply to pneumatic fluid power components, specifically ISO 15407-1 for 5/2-way valves and ISO 15407-2 for 5/3-way valves. They define the dimensions, testing methods, and performance requirements for these types of solenoid valves.
3. **ISO 5599-1 to ISO 5599-5:** These ISO standards cover the classification, dimensions, and testing methods for pneumatic control valves, including solenoid valves, with particular attention to interchangeable mounting and fluid connections.
4. **ISO 22000:** This standard relates to food safety management systems. Solenoid valves used in the food and beverage industry may need to comply with ISO 22000 to ensure the safety of the food processing environment.
5. **ISO 1020:** Specifies a standardized format for symbols to be used for directional control valves, including solenoid valves, in fluid power systems.
6. **ANSI/B93.19M:** This American National Standard covers the nomenclature and performance criteria for pneumatic and hydraulic fluid power directional control valves, including solenoid valves.
7. **IEC 60529:** Although not specific to solenoid valves, this standard defines the degrees of protection provided by enclosures against the entry of solid foreign objects and liquids. It may be relevant when specifying the environmental protection of solenoid valves.
8. **NEMA ICS 6:** Published by the National Electrical Manufacturers Association (NEMA), this standard provides guidelines for industrial control and systems equipment, including solenoid valves used in industrial applications.
When selecting solenoid valves, it's essential to consider the specific application and industry requirements. Manufacturers often provide information about the standards their products comply with. Checking for compliance with relevant standards ensures that solenoid valves meet specific quality, safety, and performance criteria.
