Overview
The SBL-16 electrostatic spark sensitivity tester can release electric shock into trace samples of energetic materials, and the reaction of the tested sample can be determined by observing, detecting sample residues, or using a gas analyzer to detect decomposition components. The experimental data is used to evaluate the sensitivity of energetic materials to electrostatic sparks, which can be generated by changing the voltage or current to produce electrostatic sparks with different energies and discharge times between 10us-1ms.
Product Details
Instrument features:
The data results can also be used to determine the safety critical parameters of the tested substance. The current standards in the industry focus on determining whether energetic materials can be safely operated and processed in experimentation, development, and production. The amplification ratio program for materials that are potentially sensitive to electric shock generally requires testing to evaluate the spark energy required for material detonation. The sensitivity measured is compared with the energy voltage during the production process to determine if it exceeds the safety limit. The electrostatic spark sensitivity test is very effective in providing such information.
