Electrostatic искробезопасность (ЭСИБ) - the status of an object, which excludes the possibility of an explosion and fire static electricity.
Electrostatic искробезопасность should be ensured through the creation of conditions, warning the static, which can be a source of ignition protection objects.
For assessing electrostatic искробезопасности object of the protection it is necessary to determine:
electrostatic искроопасность object of the protection;
Sensitivity object of the protection to the зажигающему exposed to static.
electrostatic искробезопасность object of the protection is achieved when the ratio:
, (1)
Where Wmin - the energy level, which may arise within the object or the surface, j;
TO - safety factor, selectable from the conditions permitted (safe) to GOST 1.12.004 , GOST 12.1 .010 Most likely ignition or accepted equal to 0.4 ;
Wmin is the minimum ignition energy, J..
