NIST Handbook 153
This handbook sets forth the procedures and general requirements under which the P25 CAP (Project 25 Compliance Assessment Program) operates as an unbiased third party to recognize P25 (Project 25) equipment testing laboratories.
The required P25 Compliance Test Methods and Test Cases are defined in TIA (Telecommunications Industry Association) standards and Compliance Assessment Bulletins.
This handbook constitutes the collective body of requirements that must be met by a laboratory seeking P25 CAP recognition for any of the specific test methods (for example, audio level) provided in the laboratory’s Scope of Recognition. A given laboratory’s Scope of Recognition may or may not cover all of the TIA-defined needs or recommendations.
