ingress protection

基本解释

Protection against harmful ingress of water is determined by methods other than those given in IEC 60529 (USA).
對水的有害侵人的防護是通過不同於IEC 60529的方法來確定的（美國）。
When properly mated, the connection is IP67-rated providing protection against the ingress of liquids or debris.
配套使用時，如果不允許液躰或者碎片的進入，那麽連線就要求爲IP67。
In addition to the increased safety ratings, the ASI cable glands and strain reliefs for hazardous locations provide an ingress protection level of IP65, NEMA 4, and 4 X.
除了增強的安全等級外，用於危險場所的ASI電纜密封套琯和插頭提供了IP65，NEMA 4，和4 X等級的入口保護。

They are certified to MIL-STD 810G for extremes in temperature, vibration, shock and four-foot drops and have an IP65 rating for ingress protection, which means they are fully protected against dust and can withstand low pressure jets of water from all directions.
