TM0024淋雨性能测试仪 Rain Tester1.1依据标准:本测试仪依据 AATCC 35-2000（防水：防止雨水测试或耐水 渍：雨水试验）标准要求制作1.2用途:本机适用于检测各种纺织物材料，尤其是服装纺织材料的雨水渗透防护能力和在不同雨水压力作用下织物或复合材料的拒水性能。1.3原理:模拟雨水从水平方向喷向垂直固定在不锈钢槽内的待测织物。试样背面紧贴着标准吸滤纸（测试前需称重）。水柱中的水经标准喷头喷射形成雨，水柱量可由600mm(24英寸)以300mm(12英寸)的增量调至2400mm（96英寸）。在控制条件下用水喷洒5分钟，然后通过再次称量吸水纸的重量，可以确定测试过程中样品渗透的水量。1.4 仪器规格：

1.5附件：AATCC吸滤纸500X1000mm（20X40英寸）25张，也适用于AATCC测试法8，42和70。Rain Tester. To determine the penetration resistance of fabrics or composites at different intensities of water impact. Simulated rain horizontally impacts fabric samples mounted vertically in a stainless steel bath. Samples are backed with a standardised blotting paper which is weighed before and after each test. The rain is formed by a column of water which can be adjusted from 600mm (24in) to 2400mm (96in) in 300mm (12in) increments, applied via a standardised nozzle. Can be supplied with an extension column to extend the water column to 2400mm (96in). Cannot be retrofitted, order with new Raintester. We can also provide a temperature controlled water supply which includes an electronic temperature controller, mixer tank and solenoid control valves.
