EC accuracy classes
The EC accuracy classes define the maximum variations in
measurements. They are divided into 3 classes, considering
material and temperature.
Tolerances:
Folding rulers:
Class I: ± 0.2 mm to 1 m; ± 0.3 mm to 2 m
Class II: ± 0.5 mm to 1 m; ± 0.7 mm to 2 m; ± 0.3 mm
above the joint
Class III: ± 1.0 mm to 1 m; ± 1.4 mm to 2 m; ± 0.5 mm
above the joint
Tape measures:
The tolerances of 20 °C and a tensile fore of 20 Newtons (N)
for plastic and 50 Newtons (N) for stainless steel tapes
Class I: ± 1.1 mm to 10 m
Class II: ± 2.3 mm to 10 m
Class III: ± 4.6 mm to 10 m
