这种结构在标准里叫做 bean bag, 我这里引用 ASTM F963标准的要求:( Q/ L7 `; h" G# T. B2 H
A stuffed toy or beanbag constructed of pliable
" ?1 {' U0 E; E9 @1 A) Ymaterial having seams (including, but not limited to, seams that$ z0 U5 I* A* s5 ?" y
are stitched, glued, heat sealed, or ultrasonic welded) shall
- _: H) i3 q2 @: a9 P2 r+ x' Lhave the seams subjected to a separate tension test in any% D' r/ x. z/ t5 K" m
direction using the forces specified in 8.9 and determined from' d9 M5 I3 G( }0 a. Z- G
Table 5 according to the age group for which the toy is' F2 G) f: K. @* F
intended.
1 F8 s( ]9 J6 C; i. _! x8 s
2 @6 d8 D/ B, c( e) e7 w7 J由此可见,第二种要求是必要的
b2 F7 ?) B% ^# |9 U! R. w; H. DPS:这么专业的发言,是不是加点分呢,呵呵 |
