In the flame retardant testing of the anti-collision soft pack in the inquiry room, professional testing equipment and standardized testing methods are generally used to ensure that the flame retardant performance of the soft pack material meets the relevant standards and regulations. Here are some common flame retardant testing methods:
1. Combustion test.
The combustion test is a common method to test the flame retardant properties of upholstery materials. The test evaluates the flame retardant properties of pouch materials by simulating their combustion behavior in a fire. In the combustion test, the pouch material is usually placed in a combustion testing machine to observe the combustion process of the pouch material and the residues after combustion by controlling the combustion conditions (such as flame temperature, combustion time, etc.). Based on the test results, the flame retardant properties of upholstery materials can be evaluated and classified.
2. Oxygen index method.
The oxygen index method is a method to evaluate the flame retardant properties of pouch materials by measuring their combustion behavior in a mixture of oxygen and nitrogen. In the oxygen index method, the pouch material is placed in a combustion testing machine and the combustion conditions are controlled by adjusting the ratio of oxygen and nitrogen. When the oxygen concentration is reduced to a certain level, the pouch material will not be able to continue to burn. The flame retardant properties of upholstery materials can be evaluated based on the oxygen index when the oxygen concentration is reduced to a certain level.
3. Smoke density method.
The smoke density method is a method to evaluate the flame retardant properties of pouch materials by measuring their smoke density when they are burned. In the smoke density method, the pouch material is placed in a combustion testing machine, and the combustion conditions are controlled so that it produces smoke. The flame retardant properties of the pouch material can then be evaluated by measuring the smoke density.
The above three methods are common flame retardant testing methods, but the specific method to use needs to be selected according to the characteristics and application scenarios of the soft packaging material. At the same time, when conducting flame retardant testing, it is also necessary to pay attention to complying with relevant standards and regulations to ensure the accuracy and reliability of the test results.
