 Introduction

ANSI/NCSL Z540.3-2006 is the American national standard for calibration of measurement and test equipment (M&TE), adopted in August 2006. Z540.3 is the natural evolution of ANSI/NCSL Z540.1-1994, ANSI/NCSL Z540.2-1997, and MIL-STD-45662.

Keysight Compliance to Z540.3

Keysight was an active participant in the NCSLI 171 subcommittee that authored the Z540.3 Handbook. The handbook committee devoted special attention to meeting the Z540.3 requirement: “The probability that incorrect acceptance decisions (false accept) will result from calibration tests shall not exceed 2% and shall be documented.” The Z540.3 Handbook provides details on six compliance methods.
