1)
|
Apply 10 point system inspection
standard. |
|
|
|
|
|
a. Demerit mark point's applying
range |
|
|
¥°) 1 point : defect within 1" (2.5§¯) |
|
|
¥±) 3 point : defect within 1" ~ 5"
(2.5§¯ ~ 12.5§¯) |
|
|
¥²) 5 point : excess 5" - within half
width |
|
|
¥³) 10 point : excess half width ~
entire width |
|
|
|
|
|
b. At this method, it doesn't matter
on the standard, warp threads' demerit point |
|
|
make LOSS about demerit mark point. |
|
|
A grade : 0.7 point
|
|
|
B grade :
0.71~0.8 point(LOSS 1yds) |
|
|
B grade : 0.81~0.9 point(LOSS
2yds)
|
|
|
B grade : 0.91~1.0 point(LOSS
3yds)
|
|
|
C grade : REJECT
|
|
|
Ex ) If 58"
x 50yds materials' total defects point is 35 point, |
|
|
35
/ 50 yds = 0.7 point : A grade |
|
|
|
| 2)
|
4 point system as follows |
|
|
¥°) flaws up to 3" in length
= 1 point |
|
|
¥±) flaws up to 6" in length
= 2 point |
|
|
¥²) flaws up to 9"
in length = 3 point |
|
|
¥³) flaws over 9" in
length = 4 point
|
|
|
|
|
|
a. All holes regardless
of size will be penalized 4 points |
|
|
b. The average point value per shipment
should not exceed 30 point |
|
|
100 square
yaeds |
|
|
c. The maximum number of 1 point
faults per 100 square yards in 20, |
|
|
however
the average number of 1point defects must be 14 or less per
fabric delivery |
|
|
d. 100 square yards standard point |
|
|
A grade : 25 point
|
|
|
B grade :
25-28 point (loss) |
|
|
B grade : 28-30 point
(loss)
|
|
|
C grade
: 30 point over (reject) |
|
