日焼け止めは、紫外線に耐えるように特別に設計された衣類の一種です, アウトドア活動で広く使用されています, outdoor work, and water sports. To ensure that sunscreens are still effective in providing UV protection after prolonged use, UV aging test chambers can be used to evaluate their durability and UV protection performance.

試験方法
The following is the specific role and process of UV aging test box in the application of sunscreen:

Choose sunscreen clothing materials that meet relevant standards, such as textiles with good UV barrier performance. Prepare samples of sunscreen clothing that meet the requirements of the code, including samples of complete clothing parts or cut materials.

According to the relevant standards and specifications, set the parameters of UV radiation source, light intensity, temperature and humidity in the test chamber. Ensure that the test conditions can simulate the real UV radiation environment and outdoor climate conditions.

The sunscreen sample was fixed on the sample table of the test chamber to ensure that the sample surface was fully exposed to UV radiation. The installation can be stretched or worn as required.

The UV aging test chamber was started and the samples were exposed to simulated UV radiation. Uv radiation exposure was carried out for a certain time according to the set test conditions. 同時に, humidity and heat cycling can be selectively carried out to simulate the real outdoor environment.

Regularly monitor and record changes in the performance of sunscreen clothing samples. You can use appropriate instruments and equipment, such as UV measuring instrument, 引張試験機, 等, to measure and record the UV transmittance, tensile performance, durability and other indicators of sunscreen clothing.

According to the test data and evaluation indicators, the performance changes of the sunscreen clothing samples were analyzed. The differences between the different test samples were compared to evaluate their UV blocking properties, durability and service life.

With the UV aging test chamber, the UV protection performance of sunscreen materials and designs can be evaluated to ensure that they can effectively protect skin from UV radiation damage after long use. This helps manufacturers and consumers to choose high quality sunscreen and provide reliable UV protection.

参照基準
The UV aging test of sunscreen can refer to the following industry standards:

ASTM D6554: “Standard Test Method for Determination of Transmissivity of Non-Dyed Textile Fabrics, Including UV Penetration”

ASTM D6554 is a standard published by the American Society for Materials and Testing (ASTM) for measuring the transmission properties of textile fabrics, including UV penetration. This standard can be used to evaluate the UV blocking performance of sunscreen clothing materials.

AATCC TM183: “Test Method for Transmittance or Blocking of Erythemally Weighted Ultraviolet Radiation through Fabrics”

AATCC TM183 is a standard issued by the American Association of Textile Chemists and Dye-Finers (AATCC) for measuring the transmission or blocking ability of textile fabrics to red spot-weighted ultraviolet radiation. This standard can be used to evaluate the UV protection performance of sunscreens.

特定の用途
Specific application cases include but are not limited to the following areas:

Outdoor activities: Sunscreen is widely used in outdoor activities, such as mountaineering, hiking, camping, fishing, 等. Through UV aging testing, it is possible to evaluate the UV protection performance of sunscreen clothing under prolonged outdoor exposure, ensuring effective protection of human skin.

Water sports: sunscreen is often used for water sports, such as surfing, swimming, windsurfing, 等. Uv aging tests can help assess the durability and protective performance of sunscreens after prolonged exposure to water and UV rays.

Construction and industrial sectors: In construction and industrial sectors, sunscreens are used as workwear to protect workers from UV radiation. Uv aging tests can evaluate the UV protection performance and durability of sunscreens in the working environment.

Health care: Sunscreen is also suitable for the health care sector, such as medical use, nursing facilities, and caregivers. Through UV aging testing, it is possible to evaluate the protective performance and durability of sunscreens, ensuring effective UV protection during the provision of care and services.

North-south Tide Tip: Depending on the specific market needs and requirements, it may also be necessary to refer to other standards and specifications, such as those of the International Organization for Standardization (ISO). These standards can provide guidance and reference to ensure that the performance of sunscreen clothing meets the relevant requirements.
