Introduction
1. Standard Overview and Background Analysis
GB/T37206-2018 "Test Method for Antimicrobial Performance of Organic Separation Membranes" is a national standard for the antimicrobial performance of organic separation membranes for water treatment. This standard was proposed by the National Technical Committee for Separation Membrane Standardization and is applicable to the antimicrobial performance testing of products such as organic flat membranes and hollow fiber membranes, providing a unified technical specification for the industry.
2. Comparison table of standard frameworks
| Standard dimensions | GB/T37206—2018 | International standards (ISO) | Other domestic standards |
|---|---|---|---|
| Scope of application | Antibacterial performance test of organic separation membrane | General antibacterial material test | Antibacterial testing of specific materials |
| Core indicators | Antibacterial rate (%) | Inhibition efficiency (%) | Bacteria removal rate |
| Test method | Suspension method combined with culture medium | Plate count method | Direct inoculation method |
3. Detailed interpretation of standard clauses
Term definitions
- Antibacterial:The ability of the membrane surface to inhibit or kill bacteria.
- Organic separation membrane:Separation medium made of polymer materials.
Test principle
By contacting the bacterial suspension with the membrane sample and culturing it under constant temperature, the change in the number of bacteria is measured. The specific steps include sample pretreatment, bacterial suspension preparation, culturing and eluate detection.
4. Implementation recommendations and precautions
- Equipment calibration: Ensure that the accuracy of instruments such as spectrophotometers and balances meets the requirements.
- Operation specifications: All tests should be performed in a biological safety cabinet and strictly follow aseptic operation procedures.
- Data recording: Record the parameters and results of each set of experiments in detail to ensure traceability.
5. Technology development prospects
With the advancement of antimicrobial technology, future standards may be further optimized in terms of test methods and performance indicators. It is recommended that the industry strengthen basic research and promote the development of efficient and durable antimicrobial film products.
