What is the best seismic code or standard?

The best seismic code or standard may be subjective and depending on the industry, options might be limited. There are many Telecommunication companies that use NEBS and many in the Utility Industry that use IEEE 693 for their seismic standards related to battery racks and cabinets.

What is the minimum clearance between Seismic racks?

5.3 Minimum clearance between seismic racks and any objects (including walls, equipment and other racks) is to be 4 in. (100 mm). NO SEISMIC RACKS ARE TO BE BUTTED TOGETHER END-TO-END OR BACK-TO-BACK. 5.4 Batteries should be installed in a clean, cool and dry environment where there is minimal temperature variation.

What are the different types of Seismic racks?

Seismic racks also include: side rails, end rails, corner brackets, foam spacers, rail spacers, shims and cell clamp assemblies. The styles of standard racks supplied by EnerSys are shown in Figure 1.1. 2. SAFETY PRECAUTIONS Assemble racks according to the instructions in this document WITHOUT DEVIATIONS.

Do Seismic racks have cross braces?

Seismic racks will have cross braces on the front and back of the rack and some rack styles will also have middle cross braces. DO NOT remove front and back cross braces at the same time while installing cells or after cells are installed. Only remove the front set to install cells and reinstall as soon as cells are in place on the rack.

What standards are used in a battery room?

Common standards in the battery room include those from American Society of Testing Materials (ASTM) and Institute of Electrical and Electronic Engineers (IEEE). Model codes are standards developed by committees with the intent to be adopted by states and local jurisdictions.

What is the standard for earthquake testing?

The Standard for Earthquake testing is found in GR-63-CORE. This shake testing does test all three axes but one at a time. There are criteria for passing Zone 2 and more severe testing criteria for Zone 4. Requires Triaxial Shake testing to a target SDS like IBC only OSHPD requires the test be done with live batteries.
