IS 2147:2019 is the Indian Standard (BIS) for degrees of protection provided by enclosures for low voltage switchgear and controlgear. IS 2147 extends the IP code (IS 4691) specifically for LV switchgear and controlgear enclosures, adding IK code for mechanical impact protection. IK08 (5 joules) is typical for indoor panels; IK10 (20 joules) for outdoor/industrial.
Classification and testing of enclosures for LV switchgear and controlgear, extending IP code to include protection against mechanical impact (IK code).

Practical Notes
! For electrical panels, specify BOTH IP and IK ratings: e.g., 'IP55 IK10' for outdoor MCC panels.
! IK08 is adequate for indoor panels in controlled environments. IK10 for factory floors and outdoor.
! Indoor office DB (distribution board): IP40 IK07 minimum. Outdoor feeder pillar: IP55 IK10.

Frequently Asked Questions1 What is IK rating? + IK code measures mechanical impact protection of enclosures. IK08 = withstands 5 joule impact (1.7kg dropped from 300mm). IK10 = withstands 20 joule impact (5kg dropped from 400mm). Higher IK = more robust enclosure.
