Solar Water Heater Standards (ISO 9806)

ISO 9806 is an international standard that sets quality and safety guidelines for solar water heating systems. It specifies how these systems should be designed, tested, and marked to ensure they operate efficiently, reliably, and safely over time. The standard covers aspects like thermal performance, mechanical durability, and control systems, helping consumers and manufacturers verify that solar water heaters meet consistent quality benchmarks. Overall, ISO 9806 promotes confidence in solar thermal technology by ensuring products are tested and certified according to universal criteria.
