ISO 22609 FAQ: instruments, ranges and method scope
The TNG1044 and TNG1049 instruments are designed to meet the requirements of ISO 22609 for synthetic blood penetration testing of face masks.
How does the TNG1044 support ISO 22609 testing?
The TNG1044 Face Mask Synthetic Blood Penetration Tester is specifically designed to comply with ISO 22609. It features a blood spraying distance of (300 ± 10) mm, which aligns with the standard's requirement for simulating real-world conditions. Additionally, the nozzle inner diameter of 0.84 mm ensures consistent and accurate application of synthetic blood during testing.
What specifications ensure accurate synthetic blood application on the TNG1044?
The TNG1044 includes a nozzle length of 12.7 mm, which helps maintain the correct distance between the nozzle and the test sample, ensuring uniform spray distribution. The spraying speed options of 450 cm/s, 550 cm/s, and 635 cm/s allow for precise control over the test conditions, supporting the standard's requirement for consistent and repeatable results.
How does the TNG1049 complement the TNG1044 in testing?
The TNG1049 Synthetic Blood Penetration Tester is designed to work alongside the TNG1044, offering a comprehensive testing solution for face masks. While the TNG1049 does not have detailed specifications listed, it is intended to provide additional testing capabilities that align with the ISO 22609 standard, ensuring thorough evaluation of mask performance.
What are the key parameters for synthetic blood penetration testing?
The TNG1044 provides a spraying time of 0.80 s, 0.66 s, and 0.57 s, which allows for precise control over the duration of synthetic blood exposure. This feature is essential for meeting the ISO 22609 standard, which requires specific time intervals to assess the effectiveness of face masks in preventing liquid penetration. The adjustable watching time of 10 seconds further supports the standard's requirement for accurate observation and measurement.
