这种结构在标准里叫做 bean bag, 我这里引用 ASTM F963标准的要求:
9 V/ T/ S1 E9 ]A stuffed toy or beanbag constructed of pliable* b6 q' r* c# i) w. D% O
material having seams (including, but not limited to, seams that7 I) { k1 Z4 m' ?5 t5 m
are stitched, glued, heat sealed, or ultrasonic welded) shall
* z& b3 H! L: ~' J) } K5 k: W1 y) ehave the seams subjected to a separate tension test in any1 N6 a2 c$ J4 p! l- d
direction using the forces specified in 8.9 and determined from
# M+ @6 i Y* k7 Q5 pTable 5 according to the age group for which the toy is
6 d) Z7 p# `0 J4 {' Ointended.

由此可见,第二种要求是必要的2 [- C( a+ u5 p* z- h+ t
PS:这么专业的发言,是不是加点分呢,呵呵 |
