Diameter: ≈0.875" (22.2 mm)

Weight:  ≈50 g

  - Recommended by standard for test
  - longest life when used for new or virgin product

Determines the time for cooling a chromized nickel ball from approximately 885°C (1625°F) to approximately 354°C (670°F) when quenched in 200 ml of test fluid in a metal beaker at 21 to 27°C (70 to 81°F). The quenching time is recorded by a digital timer which is energized by a photoelectric cell from light produced by the ball at 885°C (1625°F) and which is stopped when the ball becomes magnetic (Cure Point, approximately 354°C) and is attracted by a magnet to the side of the beaker, tripping a relay to stop the timer.

Minimum quantity of 2 Chrome Balls required.
