The value comes from the vehicle maker; the wrench repeats it · review
The one that publishes both numbers: ±3% accuracy, calibrated to ISO 6789-1:2017 — the standard that defines what a torque wrench accuracy claim means.
The last word Publishes the tolerance and the standard behind it. On a measuring tool, that is the product.
A 3/8 inch click wrench from 5 to 60 Nm in half-newton steps, stated at ±3% and calibrated to ISO 6789-1:2017, with a 27-piece accessory set.
Anyone can print ±3%. ISO 6789-1 defines how that figure is established and over what part of the scale it applies. A wrench that names the standard is making a claim that could in principle be checked; one that does not is making a marketing statement.
Wind it back to the lowest graduated setting after use, and never use it to undo anything. A torque wrench used as a breaker bar is out of calibration and cannot tell you so.
Sixty newton-meters. Wheel bolts need the other wrench, and both are worth owning.
Listed but with no offer on the American Amazon store — the reference exists there and nobody is currently selling it.

It is the international standard for hand torque tools: how they are classified, marked, and how their accuracy is verified. A wrench calibrated to it has had its tolerance established by a defined method rather than asserted.
Not indefinitely. Makers publish an interval in uses or years, and nothing preserves calibration except staying inside the range and storing the wrench wound back to its lowest setting.
