How do you test the water resistance of medical protective clothing?

The waterproofness test for medical protective clothing is a test that assesses the waterproofness of a material by measuring the amount of water absorbed by wet clothing. The amount of water absorbed by wet clothing can be measured in terms of the CFR, the higher the CFR the better the waterproofness.

How is the waterproofness of medical protective clothing tested?

The waterproofness of medical protective clothing can be tested by stain resistance (AATCC-127), vertical drop of water (AATCC-127) and water pressure testing (ASTM-D751).

 

Waterproofness testing is usually carried out using specialist medical protective clothing waterproofness testing equipment to ensure that medical protective clothing has good waterproofness for the safety of the user. Common waterproofness testing equipment includes hydrostatic pressure testers and spray-on water repellency testers. These devices measure the water resistance of medical protective clothing to ensure that it has good water resistance.

The hydrostatic tester is used for water resistance testing and is suitable for medical protective clothing, tightly woven fabrics such as canvas, tarpaulin, sheeting, tent fabric and rainproof clothing fabric.

 

The spray water repellency tester is used for surface moisture resistance testing of materials such as medical protective clothing, medical surgical masks, disposable medical masks, general masks, civil masks and textile fabrics.
