Product Description
【Scope of Application】:
Primarily used for testing the splash-proof and spray-proof properties of protective clothing, replacing human subjects for wearing action simulation. It can also be used for comprehensive weather-proofing tests of protective clothing, replacing human subjects for wearing action simulation.
【Related Standards】:
GB 24540-2009 "Protective Clothing - Acid and Alkali Chemical Protection Clothing"
Appendix I: Splash-proof Test Method, Appendix J: Spray-proof Test Method
ASTM F1359/F1359M-22 Standard Test Method for Liquid Penetration Resistance of Protective Clothing or Protective Covers under Shower Head on a Human Model
【Instrument Characteristics】
1. Using an integral 304 stainless steel frame structure, with a closed box, effectively blocking the splashing of test liquid and maintaining indoor hygiene;
2. Using a high-pressure, high-flow stainless steel pump, which can continuously provide test liquid under high pressure;
3. Test methods: Spray test, splash test, and limited splash test;
4. Spray test points can be selected arbitrarily to meet the testing needs of different protective clothing;
5. Spray test points use laser ranging for positioning and touchscreen operation, convenient to use;
6. Intelligent touch screen control, automatically records spray, splash, and drying time;
7. Equipped with an audible alarm to indicate the end of the test;
8. The pipelines for spray test and splash test are independent of each other, and each has a pressure stabilizing valve, making the test pressure more stable;
9. Standard dummy rotating workbench, disassembly is simple, facilitating the wearing and removing of indicator clothing and protective clothing;
10. Step motor drive, positioning is accurate;
11. Using microcomputer control, the system is stable and reliable. During the spray test, the automatic spray is at a determined position;
