Aircraft Icing and Rain Test Methods

结冰和雨水测试方法可以为您提供有关产品或部件在典型或极端环境条件下的性能的重要数据。元素执行结冰和雨水测试，符合RTCA DO-160型和MIL-STD 810aerospace and military standards.

Rain Test Methods

雨水测试用于评估因雨水、喷水或滴落引起的材料物理劣化。暴露于水会损坏产品的涂层、密封剂、外壳和整体性能。这些试验方法适用于在其使用寿命期间经历室外和高冷凝环境的产品，特别是商用和军用飞机。

Some of the rain test methods we offer include:

• Blowing rain testsuse a specified wind velocity and rainfall rate to determine how a product will endure its outdoor environment.
• Drip tests用于测量因产品暴露于以均匀速率下落的水滴中而导致的任何水渗透或积水。
• Water ingress protection testsdetermine the effectiveness of seals on the enclosures of electrical equipment.

Aircraft Icing and Test Methods

Aircraft icing tests determine the ability of the equipment to withstand naturally occurring ice and frost conditions and helps determine the need for de-icing operations. Some icing test methods may use automated chambers to combine altitude, humidity, and freezing temperatures.

For the RTCA DO-160 standard, equipment is categorized into three groups when performing aircraft icing tests: A, B, and C.

• A类适用于位于外部或非气候控制区域内的设备，在这些区域内，飞机可能因冷凝而结冰和结霜。
• B类试验为25次循环试验，模拟多次上升和下降的影响，在这种情况下，水的积聚会对运动部件和电子系统造成结构或功能损坏。
• C类用于外部区域，其中积水可能冻结，并且随着时间的推移，冰可能积聚，从而妨碍试验装置的正常运行。
