From Wikipedia, the free encyclopedia

The Telecommunications Industry Association (TIA) ANSI/TIA-942-B Telecommunications Infrastructure Standard for Data Centers[1] is an American National Standard (ANS) that specifies the minimum requirements for data center infrastructure and is often cited by companies such as ADC Telecommunications[2] and Cisco Systems.[3] The standard was updated with an addendum ANSI/TIA-942-B-1 in February 2022 from the TR-42.1 Engineering Committee.[4]

The Telecommunications Industry Association offers TIA-942 certification programs[5] through TIA-licensed certification bodies that assess and certify compliance to the TIA-942 standard.

In June 2021, the TIA TR-42.1 Engineering Committee voted to start the revision process of ANSI/TIA-942-B.[6] The standard will undergo updates during 2022. The new version of ANSI/TIA-942 which will be labelled as ANSI/TIA-942-C is expected to be released in 2023.


The ANSI/TIA-942-B specification references private and public domain data center requirements for data center infrastructure elements such as:

  • Network architecture
  • Electrical design
  • Mechanical systems
  • System redundancy for electrical, mechanical and telecommunication
  • Fire safety
  • Physical security
  • Efficiency

Newer revisions[edit]

As of August 2021, TIA has released a licensing scheme for TIA-942 audits. TIA has laid down specific criteria for organizations who wish to conduct 3rd party external audits. Once fulfilled they will be licensed as a CAB - Conformity Assessment Body. Data centers conforming to the TIA-942 standard are listed on the website; https://tiaonline.org/942-datacenters/.
