这种结构在标准里叫做 bean bag, 我这里引用 ASTM F963标准的要求:
/ I: g# _/ R* H6 J, D2 hA stuffed toy or beanbag constructed of pliable
# R8 `9 [$ X- G: d( }; X; b2 kmaterial having seams (including, but not limited to, seams that
9 U( C. w! J A0 }are stitched, glued, heat sealed, or ultrasonic welded) shall
$ C. z" \2 G. w. Dhave the seams subjected to a separate tension test in any) h2 _& _# r* ~. [3 W- a6 B
direction using the forces specified in 8.9 and determined from" z+ C+ L. L S1 `8 Q

. j* U3 U6 J }+ ~1 e9 y. ]+ U) l9 dintended.

由此可见,第二种要求是必要的6 Y" P U/ `8 _# h% Y4 d" e0 |0 G
PS:这么专业的发言,是不是加点分呢,呵呵 |
