Indice de protection IP
Use this resourceful chart on how to read IP Ratings to ensure your Healthcare Products meet your needs.
The degrees of protection are most commonly expressed as "IP" followed by two numbers, e.g. IP65, where the numbers define the degree of protection. The first digit (Foreign Bodies Protection)shows the extent to which the equipment is protected against particles, or to which persons are protected from enclosed hazards. The second digit (Water Protection) indicates the extent of protection against water. The wording in the table is not exactly as used in the standards document, but the dimensions are accurate.
The first digit in the rating is the protection against contact and foreign bodies. The second digit in the rating is the water protection factor. The third digit in the impact protection factor. It is normally displayed in the format below.
IP s l (i)
s = solids, l=liquids and i= impact (optional)
| First Index - Foreign Bodies Protection, Solids | ||
| Index | Protection against Human/Tool Contact | Protection against solid objects (foreign bodies) |
| 0 | No special protection | |
| 1 | Back of hand, Fist | Large foreign bodies, diam. >50mm |
| 2 | Finger | Medium-sized foreign bodies, diam. >12 |
| 3 | Tools and wires etc with a thickness >2.5mm | Small foreign bodies, diam. >2.5mm |
| 4 | Tools and wires etc with a thickness >1mm | Granular foreign bodies, diam. >1mm |
| 5 | Complete protection, (limited ingress permitted) | Dust protected; dust deposits are permitted, but their volume must not affect the function of the unit. |
| 6 | Complete protection | Dust-proof |
| Second Index - Water Protection, Liquids | ||
| Index | Protection against water | Protection from condition |
| 0 | No special protection | |
| 1 | Water dripping/falling vertically | Condensation/Light rain |
| 2 | Water sprayed at an angle (up to 15º degrees from the vertical) | Light rain with wind |
| 3 | Spray water (any direction up to 60º degrees from the vertical) | Heavy rainstorm |
| 4 | Spray water from all directions, (limited ingress permitted) | Splashing |

| 7 | Temporary immersion, 15 cm to 1m | Immersion in tank |
| 8 | Permanent Immersion, under pressure | For use on Titanic recovery vehicle |
| Third Index - Impact Protection, Impact | ||
| Index | Protection against impact | Equivalent mass impact |
| 0 | No special protection | |
| 1 | Protected against 0.225J impact | eg. 150g weight falling from 15cm height |
