NFPA2112 flame retardant fabric
FPA 2112: Fire Protection Flame Retardant Standard American Fire Services Association regulates industrial flash fire flame retardant protective clothing in the areas of product labeling, user information, clothing design, fibers, stitching, accessories and accessories , Signs. NFPA 2112 flame retardant protective clothing for industrial standards, is the future of industrial flame-retardant protective clothing laws and regulations established test basis. It comprehensively describes the thermal protection performance requirements of industrial flame-retardant protective clothing, including a series of thermal protection performance tests. (1) vertical burning performance test. The material is exposed to the standard flame 12 s, the flame removed, to determine whether it will be ignited and burn the length of damage. (2) The thermal stability test is basically the same as the 500 ° F oven test in the NFPA 1975 standard. (3) heat radiation and heat convection mixed role of protective performance test, referred to as TPP method. The test method is to place a 6-inch square cloth under thermal convection and radiant heat with a total energy density of 2 cal / (cm2 · s), and then record the time required to reach the second-level burn. The TPP value is time multiplied The value of cal / cal / (cm2 · s). The higher the TPP value, the stronger the protection provided by the fabric. Unlike the vertical burn test, the TPP test tells us how much the energy absorbed by the human skin through a variety of different fabrics to reach the secondary burns, that is, the higher the TPP value, the more the fabric exposed to heat and heat The body's protection is better, the unit TPP value is the most direct manifestation of thermal protection performance. (4) Thermal mannequin test. The test was performed on a 6 inch body mannequin containing 122 temperature testers and exposed to a heat of 2 cal / cm2 · s assembled by a 12 propane flamethrower, A temperature tester to collect data, to simulate the human skin may be the second and third degree burn and parts. This is the most advanced thermal burn assessment system in the world today with the same size as a real person. In order to further simulate the degree of burn in the body of an actual fire, it is used to test the degree of protection the entire suit can provide under simulated actual fire conditions. Through this test, we can predict the body may reach the secondary or tertiary burns, the lower the degree of systemic burns, the greater the chance of survival.
