这种结构在标准里叫做 bean bag, 我这里引用 ASTM F963标准的要求:
3 }0 z: Y, Y* L4 QA stuffed toy or beanbag constructed of pliable* Y* b; G, ~& Q" V1 Z! P" k5 s
material having seams (including, but not limited to, seams that8 o! ]7 J! o% v# E
are stitched, glued, heat sealed, or ultrasonic welded) shall

direction using the forces specified in 8.9 and determined from. [1 u; P& n9 |/ C2 F7 X* k4 ?4 w% A) g
Table 5 according to the age group for which the toy is( J( v% [4 R! _% R% i
intended.
. E8 l/ H' ?1 c0 z( b6 G, j& R2 K% w. ]8 _3 h
由此可见,第二种要求是必要的
0 ~" H% {) ^; @# }" w8 iPS:这么专业的发言,是不是加点分呢,呵呵 |
