This regulation is to specify technical specifications of seismic isolator in the telecommunication facilities.

1. Added technical standards for seismic isolators for telecommunication facilities (4 of Schedule 2)

- Floor response spectrum standards (0.5~33.3 Hz) reflecting the earthquake characteristics of domestic buildings by accepting the non-structural element vibration table test standards of the American Society of Civil Engineers.

- Provision of installation conditions for seismic isolators, performance verification methods, judgment conditions, etc.

2. Expansion of targets for analysis and verification of seismic performance of telecommunication facilities (2.b.5-6 of Schedule 2)

- It has been relaxed to allow analysis and verification of power equipment and ancillary equipment except for rectifiers.

Proposed date of adoption: December 2021

Proposed date of entry into force: July 2022 or later
