are calculated for static stress
in accordance with DIN 2413
Part III, but with K = 235
N/mm

When a specific factor of
safety is required, calcula-
tions should be based upon
the burst pressures shown in
the above tables.
Temperature range:
-40°C
up to 120°C without pressure
reductions.
Surface finish:
Tubes with I.D. 1.5 to 5 mm:
outside and inside oiled.
Tubes from 6 mm I.D. and
above: outside and inside
phosphated and oiled.
