pressure resistance; barotolerance
Technical term used in engineering, materials science, and biology to describe the ability to withstand pressure without failure or damage.
This container has high pressure resistance.
Deep-sea organisms exhibit excellent barotolerance.
耐水性 means water resistance; 耐圧性 is about withstanding pressure, not water.
Compound of 耐 (たい, 'endure') + 圧 (あつ, 'pressure') + 性 (せい, 'property'). The exact historical derivation is uncertain, but the components clearly indicate 'pressure-resisting property'.
