2、 Collaboration service content
High purity air is essential for control processes in clean rooms, factory manufacturing, process workshops, and other scenarios. Whether it is the manufacturing of microelectronic processors or various precision products, the pollution of small particles will have a specific impact on the performance of the products. Therefore, the space environment must control particles within a limited range. The filtration testing service ensures that the filters and systems used for filtering particulate pollutants in the system can reliably and effectively remove particles and meet relevant standard requirements.
Due to the short testing cycle and the ability to provide corresponding urgent testing services according to customer needs, comprehensive filtering performance testing services can ensure that your product meets both regulatory requirements and consumer needs.
The semiconductor and compressed air machine HCAC filter performance testing and certification service jointly launched by Su Xin and SGS includes but is not limited to the following aspects:
Resistance performance curve: Evaluate the pressure loss of the filter at different wind speeds or flow rates, providing customers with intuitive data on the efficiency of the filter operation.
0.008 μ m to 50 μ m particle removal efficiency: Test the filter's ability to remove various particles, including oily aerosols, salt aerosols, standard latex microsphere particles, and dust, to ensure the effectiveness of the filter in different particle size ranges.
EPA, HEPA, and ULPA filtration efficiency (MPPS - Most Penetrating Particle Size Determination): Conduct filtration efficiency tests on EPA (High Efficiency Air Filters), HEPA (High Efficiency Particulate Air Filters), and ULPA (Ultra High Efficiency Air Filters), especially at the Most Penetrating Particle Size (MPPS), to evaluate their highest level of filtration performance.
Dust holding capacity and life cycle comprehensive energy efficiency: measures the total amount of particulate matter that the filter can capture before reaching a specific pressure drop increase, while evaluating its energy efficiency performance throughout its entire life cycle, to help customers optimize maintenance and replacement cycles.
Rating and Standard Compliance: Evaluate MERV (Minimum Efficiency Reporting Value) rating according to ASHRAE 52.2 standard, ePx value according to ISO 16890 standard, GWMF (Particle Mass Median Diameter) rating according to EN 779, or C1 to YG rating according to GB/T 14295, to ensure that the filter complies with international and industry standards.
LRV efficiency test (Log Reduction Value): evaluates the removal efficiency of filters on microorganisms (such as bacteria and viruses), quantified by calculating the logarithmic reduction in the number of microorganisms before and after treatment.
HVAC Filter CEC Certification: Provides CEC (California Energy Commission) certification services for filters in HVAC systems to ensure compliance with California and international energy efficiency standards.
3、 Scope of tested products
The testing scope of this collaborative service is extensive, covering the following main types of filters:
HVAC filters: Air filters used in HVAC systems, including primary, medium, high, and ultra-high efficiency filters, aimed at improving indoor air quality.
Compressed air filter: a filter designed specifically for compressed air systems, used to remove impurities such as oil, water, dust, etc. from compressed air, protecting subsequent equipment and processes from pollution.
Semiconductor air filter: a filter designed for the special needs of the semiconductor industry, with extremely high filtration accuracy and reliability, ensuring that the cleanliness of the production environment meets the requirements of semiconductor manufacturing processes.
High efficiency and ultra high efficiency filters: including HEPA and ULPA filters, widely used in occasions that require extremely high air cleanliness, such as hospital operating rooms, laboratories, electronic factories, etc.
