这种结构在标准里叫做 bean bag, 我这里引用 ASTM F963标准的要求:$ g% K; z8 t- w& e) C
A stuffed toy or beanbag constructed of pliable
# T6 [' p! Q4 a% M$ r# }; Cmaterial having seams (including, but not limited to, seams that
; G7 V/ \) e6 b6 _( ^; X. w8 o( {are stitched, glued, heat sealed, or ultrasonic welded) shall3 y- P$ m d+ a
have the seams subjected to a separate tension test in any
a, B( U7 o$ Adirection using the forces specified in 8.9 and determined from
& w4 p5 B0 n/ c5 kTable 5 according to the age group for which the toy is
# O" E( _% d& Q- Z( A8 q! Zintended.
3 D5 _+ S1 P" v: m7 A, ?$ l+ @; e# Q( q% D
由此可见,第二种要求是必要的
+ @8 E5 D. J" L3 G: _- iPS:这么专业的发言,是不是加点分呢,呵呵 |
