ASTM F1862 FAQ: instruments, ranges and method scope
The TNG1044 and TNG1049 instruments are designed to meet the ASTM F1862 standard for evaluating the resistance of face masks to synthetic blood penetration.
How Does the TNG1044 Support ASTM F1862 Testing?
The TNG1044 Face Mask Synthetic Blood Penetration Tester is specifically designed to comply with ASTM F1862. It features a blood spraying distance of (300 ± 10) mm, which aligns with the standard's requirement for simulating realistic conditions during testing. The nozzle inner diameter of 0.84 mm ensures the synthetic blood is delivered in a controlled and consistent manner, supporting accurate results.
What Are the Key Specifications of the TNG1044?
The TNG1044 has a spraying speed of 450 cm/s, 550 cm/s, and 635 cm/s, allowing for varied testing scenarios that reflect different levels of exposure. The spraying time is set at 0.80 s, 0.66 s, and 0.57 s, enabling precise control over the duration of the synthetic blood application. These specifications ensure the instrument can replicate real-world conditions as defined by ASTM F1862.
How Does the TNG1049 Support ASTM F1862 Testing?
Although the TNG1049 Synthetic Blood Penetration Tester does not have detailed specifications listed, it is designed for similar testing purposes as the TNG1044. It is intended to evaluate the performance of face masks under conditions that mimic exposure to synthetic blood, ensuring compliance with ASTM F1862. The absence of detailed specifications suggests it may be used in conjunction with the TNG1044 for comprehensive testing.
What Are the Differences Between the TNG1044 and TNG1049?
The TNG1044 is specifically tailored for face masks, with a focus on the spraying distance and nozzle dimensions that match the requirements of ASTM F1862. The TNG1049, while not fully detailed, is likely designed for broader applications in synthetic blood penetration testing. Both instruments are essential for ensuring that face masks meet the necessary safety standards.
