SPF Swiss Certification




SPF is a European institution that researches and develops thermal solar technology. On the one hand, it participates in technology transfer to research and development, and on the other, it promotes trade and industry. SPF has become a connector for consumers, investors, educational institutions, producers and installation retailers. Products holding the SPF quality mark are considered to have exceptionally high quality, as products that can use this mark must pass all tests, including those according to EN 12975.
Solar Water Heater Product Testing Center
SPF is a well-known solar water heater product testing laboratory recognized by the European Union and enjoys a high international reputation. Many Chinese solar water heater products are the first choice for testing in order to export to Europe. The center is affiliated with the Swiss University of Applied Sciences. It was established in 1981 and currently has 22 full-time staff. It is a non-profit research institute operating according to business activities.
The center is the only product testing laboratory in Switzerland that is authorized by the country to issue notarized data to the society. The test results provided by the center are mutually recognized in the European Community countries, but solar water heater products in non-EU countries must pass the European recognized testing centers such as (SPF ), After passing the test, EU countries are allowed to import sales. SPF enjoys a high reputation among the EU-approved testing institutions for solar water heater products.
Testing depends on European EN standards for product quantity testing. The testing content includes:
1. Thermal performance test: daily heat of water heater per square meter, system heat loss, and thermal efficiency.
2. Safety performance testing: snow, rain, frost, electrical safety, system pressure, overheating protection.
3. Appearance quality: beautiful appearance, no scratches, no obvious flaws.
4. The quality of key components: The solar collector meets the requirements of EN12975, the pressure capacity of the water storage tank, the insulation status of the system piping, and the electrical equipment is complete and safe.

In addition to the quality inspection of solar water heaters, it is also possible to test the transmittance, coating absorption, and emissivity of solar transparent cover plates, especially quality printed glass and silicone printed with SPF, which is a quality guarantee.
An inspection report with the SPF quality mark is issued for the inspection results of each solar water heater under the conditions of sunlight intensity and ambient temperature specified in the EN12976 standard.
Most of solar glass currently uses low-carbon glass and ultra-white glass. Ultra-white glass is a kind of ultra-transparent low-iron glass, also called low-iron glass and high-transparent glass. It is a new type of high-quality glass with high quality and versatility. The light transmittance can reach more than 91.5%. Ultra-white glass also has all the processability of high-quality float glass. It has excellent physical, mechanical and optical properties, and can be processed in various deep processing like other high-quality float glass. The unparalleled superior quality and product performance make ultra-white glass have wide application space and bright market prospects.
