Impact Sensitivity Tester
This instrument employs the drop hammer method to determine the impact sensitivity of energetic materials. A sample placed between a standard steel anvil and striker is subjected to controlled falling-weight impact. The system detects explosive reactions and calculates explosion probability or the characteristic drop height (H50) for quantitative assessment. This data is used to determine whether the substance is too dangerous to transport in the form tested and to establish safety protocols for production, storage, and shipment.

Q&A
Is this instrument suitable for both R&D and routine compliance testing?
Yes. It is designed for laboratory research, formulation screening, and routine safety evaluation, and can also be used for standardized testing in quality control and regulatory assessment workflows.
Can the tester handle different sample forms such as powders, liquids, or pastes?
The system supports testing of solid and liquid energetic materials when used with the appropriate anvils and fixtures, allowing flexibility across common sample types.
How does the system help improve test repeatability between operators?
Automated control and fixed mechanical alignment reduce operator influence, helping laboratories achieve more consistent results across different users and test batches.
Is the instrument suitable for installation in a standard laboratory environment?
Yes. The footprint and structural design allow installation in typical energetic-materials laboratories, provided local safety and ventilation requirements are met.
What kind of training is required for operators?
Basic training on sample preparation, parameter selection, and safety procedures is sufficient. The automated workflow reduces the need for advanced mechanical operation skills.
