SA-SD（Type1-50）

ISO10380-50000cycles Grade：Safety Design

The standard has 4 categories of Corrugated ｍetal hose to evaluate

①Type1-50
Bending radiusType1, Life of 50000 cycles
②Type1-10
Bending radiusType1, Life of 10000 cycles
③Type2-10
Bending radiusType2, Life of 10000 cycles
④Type3
Unbraided
Type1
Excellent flexibility hose
Type2
Standard flexibility hose
Type3
Unbraided hose demanded only flexibility
※Type 1 has smaller bending radius than Type 2
-50
Repeated cycle at 50000 cycles（High-cycle-life）
-10
Repeated cycle at 10000 cycles（Standard-cycle-life）

ISO10380 Fatigue test (Test for DN size up to and including DN100)

Operation diagram

l
4 r ＋ x
r
Bending radius(left table)
a
1 cycle（5～30times/min)
x
4 × DN(mm) or 125mm, whichever is larger

Pass/Fail decision

Under pressure, the average number of times is greater than the set life and the total number of times is greater than 80% of the set life
