The primary purpose of this THTP-5024 is to determine the appropriateness and effectiveness of the participant’s methods, procedures, training, and measurement uncertainty calculations relating to the measurement of thread set plug gauges. This kit consists of ¼-20 UNC-2A, 10-32 UNF-2A, 3-56 UNF-2A.
Participants are asked to make 12 measurements that focus on the pitch diameter and major diameter (full form) for various thread standards and conditions (GO and NO GO), with values reported in inches and accompanied by measurement uncertainties.
Participants are expected to be familiar with, and have appropriate lab equipment and measurement uncertainties for calibration of similar devices.
Artifact in kit: Set of three (3) GSG, Thread Set Gage, ¼-20 UNC-2A, 10-32 UNF-2A, 3-56 UNF-2A
