The standard ensures reliability by defining strict parameters for the crimping process:
: The crimp barrel must be sufficiently deformed to compress all wire strands into a gas-tight mass, preventing oxidation. din en 60352-2 pdf
Perhaps the most important metric. The standard defines that for a given wire size and terminal type, the crimp height must fall within a narrow tolerance window (e.g., 1.2mm ± 0.05mm). Too high = loose connection. Too low = severed wires. din en 60352-2 pdf
