TIA-942

The Telecommunications Industry Association (TIA) ANSI/TIA-942-C 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 to revision C in May 2024 by the TIA TR-42.1 Engineering Committee of industry experts.^[4]

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

• Telecommunications
• Electrical systems
• Mechanical systems
• Resiliency levels
• Building architecture
• Fire safety
• Physical security
• Monitoring

TIA-942 certification programs^[5] are offered through TIA-licensed certification bodies that assess and certify compliance to the TIA-942 standard. TIA has released a licensing scheme for TIA-942 audits and 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/.
