5.2 Weight-bearing
5.2.1 Swing test
The schoolbags shall bear weight according to the provisions. It shall
respectively test the straps and handles. hang in suspension and the straps
shall be in the longest state; OR adjust the distance to the swing axis as 50 cm
~ 60 cm. Swing 30 times (a round trip is regarded as 1 time). Swing angle is
(60 ± 3)°. When swing stops, inspect whether the straps, handles, adjustment
belts, hooks and loops are firm. Within 2 mm, measure the lengths of parts as
connection role. Compared with the original length, check if the deformation
exceeds 20%.
