ASTM F2100 tester models and their published ranges

The TNG1047, TNG1062, TNG1044, and TNG1049 models are all designed to meet the requirements of ASTM F2100, which sets the standards for performance and safety of respiratory protective devices. Each instrument is tailored to specific testing protocols, ensuring accurate and reliable results for different aspects of mask performance.

Testing for Bacterial Filtration Efficiency

The TNG1047, Masks Bacterial Filtration Efficiency Tester, is specifically designed to evaluate the bacterial filtration efficiency (BFE) of masks in accordance with ASTM F2100. This instrument ensures that the test conditions align with the standard's requirements for particle filtration. The sample flow rate for both A and B is set at 28.3L/min, which is the standard flow rate used in BFE testing. This flow rate ensures that the test mimics real-world breathing conditions, providing accurate results. Additionally, the spray flow is set between 8 to 10L/min, which is crucial for simulating the aerosol challenge used in BFE testing. These specifications ensure that the TNG1047 delivers consistent and reliable results, supporting the ASTM F2100 standard.

Flammability Testing for Respiratory Protection

The TNG1062, 45 Degree Flammability Tester, is used to assess the flammability characteristics of materials used in respiratory protection, as required by ASTM F2100. The ignition time is set at (1 ± 0.05) s, which is a critical parameter for determining how quickly a material ignites under controlled conditions. This precision in ignition time helps in evaluating the flammability resistance of the material, ensuring compliance with the standard. The distance from the nozzle to the specimen is 8mm, which is essential for maintaining consistent test conditions. These specifications ensure that the TNG1062 provides accurate and repeatable flammability data, supporting the safety requirements of ASTM F2100.

Synthetic Blood Penetration Testing

The TNG1044, Face Mask Synthetic Blood Penetration Tester, is designed to evaluate the ability of masks to resist synthetic blood penetration, a key requirement under ASTM F2100. The blood spraying distance is set at (300 ± 10) mm, which ensures that the test simulates realistic conditions for liquid penetration. The nozzle inner diameter is 0.84 mm, which is important for delivering a consistent and controlled spray. These specifications ensure that the TNG1044 provides accurate results for assessing the fluid resistance of masks, supporting the standard's requirements for protection against liquid splashes.

Comparison of Testing Capabilities

Each instrument serves a distinct purpose in the testing process, ensuring that all aspects of mask performance are evaluated according to ASTM F2100. The TNG1047 focuses on bacterial filtration, the TNG1062 on flammability, and the TNG1044 on synthetic blood penetration. These models, along with the TNG1049, provide a comprehensive testing solution for respiratory protective devices, ensuring compliance with the standard's rigorous requirements.
