EN 14683 FAQ: instruments, ranges and method scope

The TNG1047, TNG1044, and TNG1049 instruments are essential for compliance with EN 14683, ensuring accurate testing of bacterial filtration efficiency and synthetic blood penetration resistance in face masks.

How Does the TNG1047 Support EN 14683 Testing?

EN 14683 FAQ: instruments, ranges and method scope - laboratory test illustration

The TNG1047 Masks Bacterial Filtration Efficiency Tester is designed to meet the requirements of EN 14683. It features a sample flow rate of A and B at 28.3L/min, which aligns with the standard's requirement for consistent airflow during testing. This ensures that the filtration efficiency is measured under controlled conditions, providing reliable results.

What Specifications Does the TNG1044 Offer for Synthetic Blood Penetration Testing?

The TNG1044 Face Mask Synthetic Blood Penetration Tester is tailored for EN 14683 compliance. It has a blood spraying distance of (300 ± 10) mm, which matches the standard's specified distance for simulating real-world conditions. This specification ensures that the synthetic blood is applied at the correct distance, enhancing the accuracy of penetration resistance testing.

How Does the TNG1049 Contribute to EN 14683 Compliance?

The TNG1049 Synthetic Blood Penetration Tester is another key instrument for EN 14683 testing. Although its specifications are not detailed, it is designed to work in conjunction with other instruments to ensure comprehensive testing. Its integration with the TNG1044 allows for standardized procedures, ensuring that all required tests are performed accurately and efficiently.

What Are the Key Specifications for Accurate EN 14683 Testing?

The TNG1047's peristaltic pump flow of (0.1～3.0)mL/min and front pressure of flow meter A of (-20～0)kPa are critical for maintaining precise control over the testing environment. These specifications ensure that the flow rates and pressures are consistent, which is essential for obtaining reliable and repeatable results in accordance with EN 14683.
