Latest active version (as of this report): IEC 60352-2:2020 RLV (Redline version) – supersedes earlier editions (2006, 1990).

Measured using 4-wire Kelvin method. Difference from a reference length of wire (voltage drop method). Minimum pull-out force (N) = function of wire cross-section (mm²) and strand class.

| Conductor cross-section (mm²) | Minimum pull-out force (N) – Class 2 (flexible) | |-------------------------------|--------------------------------------------------| | 0.05 | 5 | | 0.14 | 10 | | 0.25 | 20 | | 0.5 | 40 | | 1.0 | 70 | | 2.5 | 150 | | 4.0 | 210 | | 6.0 | 280 | | 10.0 | 420 |
