What happens if a catcher's equipment is not tested together as a combination?

In the context of catcher’s equipment, it is crucial for safety and compliance with regulations that equipment is tested and validated as a combination. When equipment is not tested together, especially for items such as helmets, chest protectors, and shin guards, the integrity and performance of the equipment may not meet the necessary safety standards.

Requesting documentation for the use of untested equipment allows the umpire to verify that the items are not only legal on their own but are also safe when used together as a set. This process ensures that the catcher’s equipment meets the standards for protection against injury while also adhering to the rules of the game.

If the equipment is not validated, it raises concerns about the safety and protection of the player. Thus, players are required to have equipment that has been validated through testing to ensure the combination is acceptable for use in the game.
