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 ~$ M% s! N, u; ?5 tA stuffed toy or beanbag constructed of pliable
$ c- ], W- }2 w8 xmaterial having seams (including, but not limited to, seams that
l4 e* b9 a; [' G' \4 {* tare stitched, glued, heat sealed, or ultrasonic welded) shall+ X: b8 E/ A4 Q; V8 O
have the seams subjected to a separate tension test in any, [( V8 i p7 c# {/ B+ _
direction using the forces specified in 8.9 and determined from
: Z8 P2 d! M& I2 o' HTable 5 according to the age group for which the toy is
" C* D2 Y E" d5 S% @$ Zintended.
# g6 J# u7 d! O5 W/ e( | h# t: H8 h
由此可见,第二种要求是必要的' U* z2 s% J7 j0 G Z
PS:这么专业的发言,是不是加点分呢,呵呵 |
