IP防護等級
根據 IEC 60 529 (EN 60 529) 標準的防護等級
IP 防護等級的標識用 IP 加兩個數字表示：
第一個數字：接觸防護和異物防護等級
| First numeral | Description | Explanation |
| 1 | Protected against solid foreign objects with a diameter of 50 mm diameter and greater | The object probe, a sphere 50 mm in diameter,must not penetrate fully 1). |
| 2 | Protected against solid foreign objects with a diameter of 12.5 mm and greater | The object probe, a sphere 12.5 mm in diameter,must not penetrate fully1). The articulated test finger may penetrate up to its length of 80 mm, but adequate distance must be adhered to. |
| 3 | Protected against solid foreign objects with a diameter of 2.5 mm and greater | The object probe, a sphere 2.5 mm in diameter, must not penetrate at all 1). |
| 4 | Protected against solid foreign objects with a diameter of 1.0 mm and greater | The object probe, a sphere 1.0 mm in diameter, must not penetrate at all 1). |
| 5 | Dust-proof | The ingress of dust is not fully prevented, but dust shall not enter to such an extent as to impair satisfactory operation of the device or safety. |
| 6 | Dust-tight | No ingress of dust at a partial vacuum of 20 mbar inside the enclosure. |
1) The full diameter of the object probe must not pass through an opening of the enclosure.
第二個數字: 防水等級
| Second numeral | Description | Explanation |
| 1 | Protected against vertically falling water drops | Vertically falling drops shall have no harmful effects. |
| 2 | Protected against vertically falling water drops when the enclosure is tilted up to 15° | Vertically falling drops shall not have any harmful effects when the enclosure is tilted up to 15° on either side of the vertical. |
| 3 | Protected against spraying water | Water sprayed at an angle of up to 60° on either side of the vertical shall have no harmful effects. |
| 4 | Protected against splashing water | Water splashed on the enclosure from any direction shall have no harmful effects. |
| 5 | Protected against water jets | Water directed at the enclosure from any direction in a jet shall have no harmful effects. |
| 6 | Protected against powerful water jets | Water directed at the enclosure from every direction in a powerful jet shall have no harmful effects. |
| 7 | Protected against the effects of occasional submersion | Water must not ingress to such an extent as to cause harmful effects when the enclosure is temporarily immersed in water under standardised pressure and time conditions. |
| 8 | Protected against the effects of continuous submersion in water | Water must not penetrate to such an extent as to cause adverse effects when the enclosure is permanently immersed in water under conditions agreed between the manufacturer and the user. However, the conditions must be more difficult than for numeral 7. |
| 9 | Protected against high-pressure/steam jet cleaning | Water directed at the enclosure from every direction under greatly increased pressure shall have no harmful effects. |
Example of a protection category, e.g. IP 43:
First numeral = 4: Protected against solid foreign objects with a diameter of 1.0 mm and greater
Second numeral = 3: Protected against spraying water
NEMA 防護等級
電器製造商協會
電器製造商協會（National Electrical Manufacturers Association，簡稱 NEMA）位於美國華盛頓，是一家技術標準機構，負責制定一系列技術標準，但機構本身並不從事產品核對總和認證工作。
下面的 NEMA 等級分類表大致描述了保護人員免受意外接觸設備和保護控制櫃免受外部因素影響的不同等級。
ECB•S 認證
不僅是元件檢測
