Heavy zinc-coating Galvanized Steel Wire Strand for Vineyard and Orchard as per EN 50189

Table 1. Initial Settings for Determining Stress 1% Extension
Nominal Wire Diameter		Initial Stress	Initial setting of extensometer for a gauge length of 250mm²
mm		N/mm²
1.24	2.25	100	0.125
2.25	3	200	0.25
3	4.75	300	0.375
4.75	5.5	400	0.5
For other gauge lengths, multiply the initial setting by the gauge length in mm divided by 250
