Introduction to rain resistance tester

Introduction to rain resistance tester

Rainproof tester can detect the water-repellent performance of fabrics or composite materials under different rain pressures.

product details:

This instrument can simulate rain spraying from the horizontal direction to the fabric to be tested that is fixed vertically in a stainless steel tank. The back of the sample is tightly attached to the standard suction filter paper (it needs to be weighed before and after testing). The water in the water column is sprayed through the standard sprinkler head to form rain, and the water volume of the water column can be adjusted from 600mm (24 inches) to 2400mm (96 inches) in 300mm (12 inches) increments.

Not retrofittable, can be ordered with a new rainfall tester. We can provide temperature controlled water supply systems, which include electronic temperature controllers, mixing tanks and solenoid control valves.

Detection principle:

Simulate rainwater spraying from the horizontal direction to the fabric to be tested fixed vertically in the stainless steel tank. The back of the sample is tightly attached to the standard suction filter paper (weighing is required before testing). The water in the water column is sprayed through the standard sprinkler head to form rain. The water column volume can be adjusted from 600mm (24 inches) to 2400mm (96 inches) in 300mm (12 inches) increments. The amount of water penetrated by the sample during the test can be determined by spraying it with water for 5 minutes under controlled conditions, and then by weighing the absorbent paper again.

Operating Instructions and Instructions:

1. Place the back of the sample against the standard suction filter paper (weigh it before and after testing). The water in the water column is sprayed through the standard sprinkler head to form rain, and the water volume of the water column can be adjusted from 600mm (24 inches) to 2400mm (96 inches) in 300mm (12 inches) increments.

2. An LCD color touch screen with an interactive user interface can be provided, and ISO and AATCC test standards, water temperature, water column height, and test time can be preset. The built-in reservoir can recycle the water sprayed on the sample, and the reservoir is equipped with a heater to control the water temperature. The precise water pump can automatically maintain the water column on the nozzle to the set height.

3. Equipment and materials

3.1.AATCC rain tester

3.2. White AATCC absorbent paper

3.3. Distilled or deionized water

3.4. Balance, accurate to 0.1g

4.Sample

4.1. Take at least three samples, each 20X20cm. The sample and absorbent paper were placed in a standard atmosphere to condition the humidity for at least 4 hours before testing.

5.Process

5.1. Place a 15.2cmX15.2cm standard absorbent paper behind the sample, and weigh the standard absorbent paper to the nearest 0.1g. Clamp the specimen to the specimen holder on a vertical rigid surface. The sample is placed in the middle of the spray, 30.5cm away from the nozzle. Spray the 27±1°C water flow directly onto the sample horizontally for 5 minutes. After spraying, carefully remove the absorbent paper and quickly weigh it, accurate to 0.1g.

6. Rating

6.1. Calculate the increase in weight of the absorbent paper during the 5-minute spray time, and average the three results.

7.1. Report averages. If it is greater than 5.0g, it will be reported as +5.0g or 》5.0g.
