Tape measurement accuracy – EU class I and II. Th
e accuracy is measured at 20°C and 50 N pull force for steel tape and 20°C and 20 N pullforce for fibreglass tape.

Example: If outdoor temperature is –10°C, the difference will be –30°C and so, for an 8 m long steel tape measure, the change in length will be –3.0 mm.
