タイトル：ANSI/TIA-1152 Requirements for Field Test Instruments and Measurements for Balanced Twisted-Pair Cabling (Sep 2009)
In 2007, the Telecommunications Industry Association (TIA) TR-42 Engineering Committee began development of the ANSI/TIA-568-C series of structured cabling Standards. In 2008, it was agreed to remove the specifications for field test instruments that are used to test balanced twisted-pair cabling from the ANSI/TIA-568-C series and place them in a standalone document; ANSI/TIA-1152.
The international equivalent is IEC 61935-1 which has the same values for Level IIe, III, IIIe but includes Level IV for Class F testing to 600 MHz.
IEC 61935-1 Ed.4 (Draft) will support Class FA to 1000 MHz with a Level V accuracy specification.
