Summary:

This Mask Flame Retardant Performance Tester is is mainly used to test the burning performance of medical masks after contacting the flame at a certain linear speed. It is a special test instrument for the flame retardant performance of medical masks. It is also used for the determination of the flame retardant properties of woven fabrics, knitted fabrics, coated products, laminated products, etc. such as continued burning, smoldering and charring tendency.

The Flammability test procedure evaluates the flammability of medical textiles including face masks, surgical gowns, and drapes. The test method is designed to comply with 16 CFR Part 1610. This test is required by the ASTM F2100 (Standard Specification for Performance of Materials Used in Medical Face Masks) to ensure that all face masks meet the requirements for Class 1 flammability. Testing is also required for 510(k) submissions to the FDA. In addition to the Flammability test, Nelson Labs can perform all ASTM F2100 testing.

Standards:

GB 19083-2010: Technical requirements for protective face mask for medical use.

YY0469-2011: Surgical mask.

GB2626-2006: Respiratory protective equipment — non-powered air-purifying particle respirator–6.15 Flammability

BS EN136-1998: Respiratory protective devices – Full face masks – Requirements, testing, marking

Principle:

When a medical mask is accidentally exposed to flames, its flame retardant performance is directly related to the safety of medical personnel. The flame retardancy of masks is one of the important physical indicators to measure the quality of medical masks. The test principle of the instrument is to install the mask sample on the head mold sample holder in a simulated actual use state. The mask with the head mold sweeps over the igniter with a constant flame height at a certain linear speed, observe the mask combustion, and record the continued combustion and smoldering Time to judge whether the mask is qualified.

Main features:

* The mask fixture is a metal human head model, which can fully simulate the actual use state of the mask.
* The burner is equipped with combustible gas interface such as propane (liquefied gas).
* The height of the burner is adjustable.
* Automatic timing positioning of the burner.
* The surface of the burner intake pipe is covered with a fireproof tube, which is resistant to high temperature of 1300 ℃ to ensure the safety of the experiment.
* The actual burning time and flame retardant time are automatically recorded, and the digital display.
* Using high quality motor, the instrument runs smoothly.
* The surface of the instrument is made of 304 stainless steel, which is durable, neat and clean in appearance.
