Purpose:

50Sealed explosion-proof protective containerEPC 010Used for laboratory testing of risks that may ultimately result in hazardous explosive effects during safe execution. This container is designed to accommodate up to16 barThe detonation pressure (in accordance withEN 14460 -Explosion proof equipment standard), and verified to withstand up to10gramT-N-TEquivalent detonation load while maintaining its airtightness.

Technical parameters:

1. Stainless steel container, with a free volume of approximately50Liter, inner diameter345mmThe length of the tubular part489mm.

2. Explosion proof and airtight, capable of withstanding up to16 barThe detonation pressure or10gT-N-TThe detonation of explosives (using)10gramSemtex 1APlastic explosives undergo verification testing

3. Airtight design, allowing for analysis or adjustment of the release of reaction gases through output valve sampling

4. The input valve is used to flush the chamber with compressed air or create a specific gas environment

5. Quick opening and closing mechanism with four threadsUShaped lock buckle

6. The lid is folded to the left through a hinge, fully exposing the unobstructed internal volume of the container

7. Use compressed air for rapid ventilation through open input and output valves（< 5Minutes)

8. Front observation window (diameter)175mm）Equipped with explosion-proof composite glass, suitable for video recording of experiments

9. Side observation window (diameter)80mm）Equipped with explosion-proof composite glass, suitable for experimental lighting

10. 9An airtight explosion-proof cable inlet, suitable for diameters1to7mmCables such as thermocouples andRTDTemperature gauge, fiber optic cable, electric heating cable, battery cable, other signal cables), equipped with internal plugins for installing flame-retardant cable protection hoses

11. Back sensor flange, effective diameter104mm(Used to install pressure, optical flash, heat flux, or other sensors onto the longitudinal axis of the chamber)

12. The replaceable top protective plate protects the top wall of the chamber from sharp flames

13. Detachable ash tray for easy cleaning after testing or sampling of solid residues

14. Bottom bracket, used to place controllers, data acquisition devices, or tools

15. Low cost consumables required for operation (for windows)5mmthickPMMAInternal protective plates, covers, and windowsOThe maintenance workload for the O-ring and gasket is minimal
