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%.

5.2.2 Static, falling tests
