The gas content inside high pressure die cast parts varies between 10 and 50 cc/100 g (normalised to ambient temperature and pressure) ( Badini et al., 2002 ). Moreover, the gas volume is compressed by up to 1000 times during intensification under a metal pressure of 100 MPa during the casting process.

Plastics with good mechanical properties - Ensinger

The impact strength of thermoplastics is measured either by Charpy or Izod impact tests. A small rectangular rod is struck by a pendulum at high speed and the energy absorbed while breaking the specimen is measured; the higher the value, the better the impact resistance.

Properties of Concrete Blocks — Strength

It is probably safe to assume that the minimum crushing strength of well-made blocks, 1 to 5, is 1,000 pounds per square inch at 1 month and 2,000 pounds at 1 year.
