Repeated free fall reliability classes

The repeated free fall reliability class of a smartphone or a slate tablet shall be determined on the basis of the number of falls without defect as set out in the table below. The number of falls without defect shall be determined in accordance with Annex IV, point 4.

180 ≤ n < 270

156 ≤ n < 208

140 ≤ n < 210 (in un-extended state) and
35 ≤ n < 45 (in fully extended state)

130 ≤ n < 182 (in un-extended state) and
15 ≤ n < 20 (in fully extended state)

E
(least robust)

-

n < 52

-

n < 52 (in un-extended state) and
n < 5 (in fully extended state)

* For foldable products, both requirements for the respective energy label class must be met.
