As the demand for masks increases, the durability and performance of masks becomes critical. The UV aging Test Chamber can simulate real UV radiation and climatic conditions to evaluate the weather resistance of masks.
Test procedure
The specific process of UV aging Test Chamber in mask application:
Material selection and preparation: Select the mask material that meets the requirements. Masks are usually composed of multiple layers of fabric, filter media and ear straps, and different material combinations can have an impact on the performance of the mask.
Set test conditions: According to the test requirements, determine the parameters such as UV radiation source, temperature, humidity and radiation time in the Test Chamber. These conditions should be able to simulate real UV radiation and climatic conditions, such as sunlight exposure, high temperature, humidity, etc.
Mounting the sample: Fix the mask sample on the sample table of the Test Chamber to ensure that the surface of the sample is exposed to ultraviolet light sources. Different types and sizes of mask samples can be selected for testing.
Start the test: Start the UV aging Test Chamber and expose the mask sample to simulated UV radiation. According to the set test conditions, the radiation is for a certain period of time. At the same time, the damp-heat cycle can be selectively performed to simulate the real climate environment.
Monitoring and recording: Regularly monitor and record the performance changes of mask samples. Appropriate instruments and equipment, such as pressure differential meters, filtration efficiency Testers, etc., can be used to measure and record the filtration efficiency, breathing resistance, damage degree and other indicators of masks.
Evaluation results: According to the test data and evaluation indicators, analyze the aging degree and performance changes of the mask samples. Compare the differences between different test samples to evaluate the durability and performance of the masks.
The testing of masks through the UV aging Test Chamber can provide durability assessment of mask materials, guide manufacturers and users to choose suitable materials, and ensure the performance and protective effect of masks in actual use. This helps to provide high-quality and reliable mask products to meet different use scenarios and needs.
Industry standard
In the UV aging test of masks, the following industry standards can be referred to:
ASTM F2100 is a standard issued by the American Society for Testing and Materials (ASTM) for the specification requirements for the properties of medical mask materials. The standard includes requirements for filtration efficiency, breathing resistance, fluid barrier properties, and more.
ISO 22609 is a standard published by the international standards organization (ISO) to test the resistance of medical masks to the penetration of synthetic blood. This test method evaluates the liquid barrier properties of masks.
GB/T 32610 is a Chinese national standard for technical specifications for daily protective masks. The standard specifies the performance requirements of masks such as filtration efficiency, respiratory resistance, and bacterial filtration efficiency.
