Copper crushers are used in ballistic testing to measure the pressure developed by fired ammunition. Here are some general specifications and details about copper crushers:
- Material: Typically made from copper.
- Shape: They are usually cylindrical.
- Size: The exact dimensions can vary, but common sizes include lengths of around 0.5 inches (12.7 mm) with diameters of about 0.2 inches (5.08 mm).
- Application: Used in firearms testing to determine chamber pressures. The crusher is placed in a fixture where it is then compressed upon firing a ballistic device.
- Measurement: After firing, the amount of deformation (crush) experienced by the copper cylinder is measured. This deformation is then used to calculate the pressure exerted during the shot.
- Standards: Adhering to military and industry standards (e.g., NATO standards in military settings).
For precise information about a specific type of copper crusher, consulting the manufacturer or referencing technical military specifications such as the NATO EPVAT (Electronic Pressure, Velocity, and Action Time) testing standards may be necessary.
