这种结构在标准里叫做 bean bag, 我这里引用 ASTM F963标准的要求:7 E0 p8 Q* y- A; c. T) g+ I
A stuffed toy or beanbag constructed of pliable
1 F ^, A/ x7 Umaterial having seams (including, but not limited to, seams that: Z( W( H) v6 |) z
are stitched, glued, heat sealed, or ultrasonic welded) shall# O$ Z, j0 A4 k2 W1 {. P, {- Z/ M
have the seams subjected to a separate tension test in any& Q' O" G2 b+ H- O1 m% @$ d- t
direction using the forces specified in 8.9 and determined from
* T* C0 W1 I5 l" Q# O, d& ITable 5 according to the age group for which the toy is6 J& L [. `$ |
intended.
6 z; G& H. j, q8 ^# {, w
( \& l/ C2 F' B+ }* m由此可见,第二种要求是必要的
" q% ]9 o) v% R+ QPS:这么专业的发言,是不是加点分呢,呵呵 |
