Sydros Filter Testing and Certification Procedures
Sydros Water GmbH is an innovative German company dedicated to developing and manufacturing state-of-the-art water filtration systems. Our team of experienced water experts and technology developers combines expertise with cutting-edge technology to create solutions for clean, healthy and safe water. From household filters to industrial applications, we offer filter systems "Made in Germany" that effectively remove pollutants such as microplastics, PFAS, heavy metals and other contaminants. Our goal is to return water to its purest form and make a sustainable contribution to water quality worldwide.
1. Introduction Sydros Water GmbH has developed a unique water test bench that allows us to test and certify our filters under realistic conditions. The test bench simulates the water pressure of German households (0.5 to 3 bar) and enables long-term observations to analyze the performance of our filters in terms of physical parameters such as pressure loss, temperature, flow and pressure difference. Our filters are designed, developed and tested using the latest technology - a process that underlines our commitment to quality and innovation. Every tested product receives the German Sydros certificate, which stands for "tested, analyzed, and approved in Germany".
2. Preparation
Sample preparation:
- A water sample with defined initial parameters is created or provided (e.g. tap water).
- Standardized test conditions such as temperature, pressure and volume are defined and recorded.
Product preparation:
- The water filter to be tested is installed according to the manufacturer's instructions.
Device initialization:
- The test bench and all sensors are calibrated.
- Sensors for pressure, flow (l/min), pressure difference and volume are connected for monitoring according to the specific test requirements.
Documentation of the procedure:
- All test methods, equipment used, protocols and test conditions are recorded in writing.
- All steps and results are reproducible.
3. Analysis before filtration
Carrying out the input measurement:
- water test bench:
- Measurement of flow velocity and volume.
- Recording the inlet pressure.
Logging:
- Results are documented in detail and kept for reference.
4. Filtration test
Carrying out the filtration:
- The water sample is passed through the filter.
- Measuring filtration time to evaluate efficiency and flow capacity.
Operating parameters:
- Pressure drop (if any) across the filter medium is recorded.
- Constant or fluctuating flow rate is checked and noted.
5. Analysis after filtration
Carrying out the initial measurement:
- water test bench:
- Measurement of outlet pressure and flow parameters over a defined period of time is carried out.
Logging:
- Results are documented to evaluate long-term effectiveness.
6. Evaluation and certification
Comparison of measurement results:
- Before and after comparison of the physical parameters.
- Identification of deviations or changes in performance.
Protocol creation:
- Summary of the results in a standardized test report:
- Description of the product.
- test methods and equipment.
- raw data (measured values).
- Evaluation according to defined criteria.
Certification:
- Products that have been successfully tested receive the Sydros seal.
- The certificate is clearly declared as an internal test mark.
- Wording: "All water filters undergo our internal testing procedure, which is carried out under standardized test conditions."
Provide evidence:
- All test results and protocols are archived for presentation upon request.
Product liability:
- Test results must correspond to reality in order to avoid liability claims (§ 823 BGB).
7. Completion and validation
Archiving:
- Test reports are kept for at least 5 years in order to comply with legal requirements and customer requests.
Validation:
- The test procedure was validated and made available by Endress & Hauser GmbH and Dradura GmbH.
Regular audits:
- Test methods are regularly reviewed and updated to meet legal requirements.
- The test mark is clearly defined as an internal testing procedure.
Truthful information:
- All information must comply with legal requirements (Section 5 of the German Act Against Unfair Competition) and must not be misleading.
Traceability:
- Each test report is clearly assigned to a product and a batch.
