דרגת הגנה IP:

דרגת ההגנה מורכבת תמיד משתי ספרות המגדירות 2 הגנות שונות. הספרה השמאלית מייצגת את דרגת ההגנה מפני מגע אנושי כאשר 1 זה המינימום ו- 6 מקסימום. הספרה הימנית מגדירה את דרגת האטימות לנוזלים כאשר  כאן 1 זו דרגת המינימום ו- 7 היא דרגת המקסימום.

דוגמא: IP66 נחשב לטוב ביותר בעבור אפליקציות רפואיות.
