Which of the following is NOT included in a high mass impact test according to ANSI Z87.1?

Explanation:
High mass impact testing in ANSI Z87.1 checks eyewear performance when a heavy object strikes at a relatively slow speed. It uses a 500 g mass dropped from a height of 50 inches toward the eyewear, and the contacting end can be pointed or blunt to simulate different kinds of heavy object impacts. This test does not involve firing a projectile at high speed. The fast-velocity scenario—where a projectile is launched at about 150 feet per second toward the eyewear—belongs to a separate high velocity impact test. So the statement about firing at 150 ft/s is not part of the high mass impact test, while the descriptions of a heavy object, a 500 g mass, and a 50-inch drop are consistent with it.
