GB T 26373 Bactericidal Testing of Disinfectant Products
The GB/T 26373 standard is a crucial tool in the evaluation and certification process for disinfectant products, particularly focusing on their bactericidal efficacy. This standard was developed to ensure that disinfectants meet stringent requirements regarding their ability to kill bacteria effectively. The standard is widely recognized within China’s regulatory framework and is essential for manufacturers looking to comply with local laws and regulations.
The primary goal of the GB/T 26373 test is to assess the bactericidal efficacy of disinfectant products against a broad spectrum of microorganisms, including common pathogens. This ensures that the product can be trusted to provide effective hygiene solutions in various settings such as healthcare facilities, food processing plants, and public spaces.
The testing procedure involves exposing a known quantity of bacterial cultures to the disinfectant under controlled conditions. The bacteria are then incubated for a specified period after exposure to the disinfectant. After incubation, the number of surviving bacteria is compared to a control group that was not exposed to the disinfectant. A significant reduction in bacterial count indicates effective bactericidal activity.
The GB/T 26373 standard specifies several key parameters for testing, including the types of microorganisms used, the concentration and exposure time of the disinfectant, and the incubation period post-exposure. These parameters are critical to ensuring that the test results accurately reflect the bactericidal performance of the product.
The standard also provides detailed instructions on how to prepare bacterial samples for testing, which is crucial for obtaining reliable results. Proper specimen preparation ensures that the bacteria used in the test are viable and representative of the types of microorganisms the disinfectant may encounter in real-world applications.
Once the test is completed, the results are evaluated based on predefined criteria. If the bactericidal activity exceeds the minimum threshold set by the standard, the product can be deemed effective for its intended use. Compliance with GB/T 26373 not only ensures that disinfectant products meet local regulatory requirements but also enhances consumer confidence in the hygiene and safety of these products.
The importance of bactericidal testing cannot be overstated, especially given the increasing demand for safe and effective cleaning solutions. By adhering to standards like GB/T 26373, manufacturers can ensure that their products are not only compliant with local regulations but also meet or exceed international safety and efficacy standards.
The GB/T 26373 standard is widely accepted within China’s regulatory framework and is essential for ensuring the effectiveness of disinfectant products. This ensures that these products can be trusted to provide effective hygiene solutions in various settings such as healthcare facilities, food processing plants, and public spaces.
Scope and Methodology
| Test Parameter | Description |
|---|---|
| Bacterial Species | The standard specifies a range of bacterial species that are commonly used in testing, including Escherichia coli (E. coli) and Staphylococcus aureus. |
| Disinfectant Concentration | The concentration of the disinfectant must be within the specified range to ensure accurate bactericidal efficacy assessment. |
| Exposure Time | Bacteria are exposed to the disinfectant for a defined period, typically ranging from 5 minutes to 30 minutes. |
| Incubation Period | The bacteria are incubated post-exposure to allow them to recover and grow. This is usually set at 24 hours. |
The scope of the GB/T 26373 standard encompasses a wide range of disinfectant products, including those used in healthcare settings such as hospitals and clinics, food processing plants, public spaces like schools and airports, and other environments where hygiene is critical. The methodology outlined in this standard ensures that all products undergo rigorous testing to ensure their effectiveness.
