Intermediate precision condition
A condition set spanning the same procedure and location over an extended period, allowing other factors (operator, reference standard, time) to vary.

Measurement trueness
Closeness of agreement between the average of infinitely many replicate measured values and a reference value. Trueness relates inversely to systematic error, not random error.
VIM (JCGM 200:2012) 2.14
Measurement bias
The estimate of a systematic measurement error — typically the difference between the mean of repeated indications and an accepted reference value.

Intermediate measurement precision
Measurement precision under intermediate precision conditions — the realistic "within-lab, over months" figure that belongs in most uncertainty budgets.
VIM (JCGM 200:2012) 2.23
Measurement reproducibility
Measurement precision under reproducibility conditions — what interlaboratory comparisons quantify.
VIM (JCGM 200:2012) 2.25
Repeatability condition of measurement
A condition set that includes the same procedure, operators, measuring system, operating conditions, and location, with replicates over a short period.
