Dear Readers,
It is Informed to you due to work load and personnel reasons, self could not be posted any Articles in past five months. I am really very sorry. Let us go to the post.
As you may aware that Electric and electronic equipment’s deteriorate or malfunction when water or dust enters to the device. The IEC has developed the ingress protection (IP) ratings, which grade the resistance of an enclosure against the intrusion of dust or liquids.
In this article, we are going to discuss the international rating system that classifies devices for different environmental conditions. That rating system is called the Ingress Protection or IP rating as it is commonly referred to. Sometimes also interpreted as International Protection Rating.
An IP rating is usually a two-digit grading system that’s applied to the enclosure of a mechanical or electrical item. First digit for solids and second digit for Liquids. Occasionally followed by a letter denoting specific materials, hazards or testing scenarios. an additional letter may be appended to the end of an IP rating.
The first characteristic numeral designates the degree of protection of persons against the contact with live or moving parts inside the enclosure, and machines against ingress of solid foreign bodies. The first digit will be a number between 0-6.
The second digit in an IP rating will be a number between 0-9, denoting the quality of resistance to moisture ingress at varying intensities, angles, depths and pressures of exposure or immersion.
Following table furnish the details of first and second characteristic numerals of standard degree of protection.
