The waterproofing layer of the glove is tested for permeability resistance under pressure conditions with chemical liquids to observe whether it has visible liquid penetration at a specific time and under a specific pressure sequence. 【Relevant Standards】

GA7-2004 Fire Gloves Appendix D

【Scope of application]: The waterproofing layer of the glove is tested for permeability resistance under pressure conditions with chemical liquids to observe whether it has visible liquid penetration at a specific time and under a specific pressure sequence. [Meet the standard]:GA7-2004 Fire Gloves Appendix D [Instrument features]: 1. The instrument adopts a gas source that can provide (0.5~30±0.1) kPa air pressure to continuously pressurize the specimen, and is not limited by the space of the test site. 2. The air pressure range can be freely adjusted, and the adjustment range (0.5~30) kPa; 3. Color touch screen display and operation; 4. The specimen clamping pad is processed with imported special aluminum profiles, which is lightweight, smooth on the surface, and will never rust; 5. The instrument adopts imported special aluminum brushed panel, equipped with metal buttons, which is sensitive to operation and not easy to damage; 6. The instrument specimen clamping device is equipped with locking protection to prevent synthetic blood from splashing everywhere; 7. The clamping force is accurate and reliable; 8. The test tank is equipped with a special placement device to facilitate customer operation; 9. Automatic completion: 0kPa timing for 5 minutes, switch to 13.8kPa timing for 1 min and then switch to 0kPa timing for 54 minutes, alarm prompt observation. 【Technical Parameters】: 1.
