这种结构在标准里叫做 bean bag, 我这里引用 ASTM F963标准的要求:+ S- d d$ h6 M/ ?: m# _
A stuffed toy or beanbag constructed of pliable
4 j1 E- N+ Q, bmaterial having seams (including, but not limited to, seams that8 u# \- b$ G9 l. C, |. l* }
are stitched, glued, heat sealed, or ultrasonic welded) shall
% F0 S3 J" F( j/ Lhave the seams subjected to a separate tension test in any
7 k; u2 }/ i* k% h! vdirection using the forces specified in 8.9 and determined from
+ ]/ G3 J- a, e- ITable 5 according to the age group for which the toy is) R" ^1 T; W1 { h4 c1 W
intended.
& q. w% s0 s: a( u! [, w9 D! E. Z+ q5 |
由此可见,第二种要求是必要的
