Summary of the following standards: UNE 10.323.78, C 431, IEC 630, IEC 144 and NFC 10.010

All casings in service are exposed to a wide range of external influences against which they must be protected in accordance with the importance or safety of the elements they house, or in accordance with their strategic situation inside the installation.

This technical document has been extracted from several different standards, which select three external influences to consider in protection: The presence of solid bodies, the presence of water and the possible impacts or mechanical efforts that a casing in operation can support.

The protection level (IP) is formed by three figures related to these three influences. This protection level should always be taken figure by figure, and none of these figures must be less than the minimum stated for the installation.

Summary of the following standards: UL 94, IEC 695-2-2,CEI 50-11 and ASTMD 635

By nature, the casings house elements that when in operation causes thermal heating. Under normal conditions this heating does not cause any damage to the installation. However, the abnormal operation of some elements can cause overheating or discharges that put the safety of the installation at risk.

In the same way, once a flame has appeared, it is extremely important that once the origin of this heat source has stopped burning, the actual casing stops burning in the minimum possible time (seconds).

In the following table we can find the definition of the different self-extinguishing levels, as well as the tests carried out to obtain them.
TYPE TEST-INSTRUM GUIDE-LINES TEST PURPOSE TEST RESULT TEST CONDITIONS
SOURCE DURATION DATA
UL UL94º Evaluation of the time a test tube sample can continue to burn when it is removed from the direct flame.
  • V0: if the test tube
    burns for less than 5 sec. before extinguishing itself.
  • V1: if it burns for less
    than 25 sec.
  • V2: if it burns for less than 25 sec. with flaming drops.
  • HB: if it burns for more
    than 25 sec.

Valuation of in how long and speed the test tube sample burns when it is retired of the direct flame.
  • Inflammable: if the probetano burns.
  • Autoextinguible: if it burns in an inferior length to 100 ms.

Verification of which the abnormal heatings produced by overloads and bad contacts do not compromenten the security of the insulating material. The test is of ignition. The thread is pressed against the test tube with a certain force and penetrates in the interior 7 mm. The flame must be extinguished to the 30 s. of to be retired the incandescent thread.
  • Temperature: 650 ºC for materials that do not maintain parts in voltage.
  • 750 ºC for materials that maintain to parts in
