美国纺织四分制与十分制检验标准分制

美纺织四分制与十分制检验标准

一、AATCC检验及抽样标准：

AATCC standard of Test and Sample

1．抽样数量：总码数的平方根乘以八.

Sample qultity: 8*the square root of total yard qualtity 2．抽箱数：总箱数的平方根.

Carton quatity: the square root of total carton qualtity 二．四分制检验：

Four Point System

1．１＂－３＂扣１分 1 point deducted

３＂－６＂扣２分 2 point deducted

６＂－９＂扣３分 3 point deducted

９＂以上扣４分 4 point deducted

２．疵点的评分原则：

The grade principle on defect:

Ａ，同一码中所有经纬向的疵点扣分不超过4分．

the total deduction can not surpass 4 point on all warp and weft in the same yard.

Ｂ，破洞不问大小扣４分．

The deduction shall be 4 point on the broken hole.

Ｃ，布边一英寸内不扣分．

It is not deducted for edge in one inch.

Ｄ，连续性疵点须开裁或降等外品．

The fabric with continuous defect should be cutted out or degraded.

E ，任何大于针孔的洞均扣4分。

The deduction shall be 4 point on the hole bigger than pinhole F，无论经向或纬向，无论何病疵，都以看得见为原则，并按疵点评

分给予正确扣分．

No matter whether on weft or warp,na matter waht defect,all is due to the appearance found and correct deduction according to the defects.

G，除了特殊规定（比如涂层上胶布），通常只需检验布的正面。Except the special instrction(like coated fabric),it is only to check the face side of fabric.

３．等级计算方法有两种：

Two methods of grade counting

Ａ，以线长度为基准计算：

Counting on the base of thread length

１００Ｍ扣分不超过５０分为Ａ级（为可接受范围）．

The total deduction within 50 points per 100 meter is graded as A(accepted).

１００Ｍ扣分超过５０分为Ｂ级．（为不可接受范围）.

The total deduction over 50 points per 100 meter is graded as B(unaccepted).

Ｂ，以平方码为基准计算：

Counting on the base of square yard

每百平方码四十分(为可接受范围)

The total deduction within 40 points per 100 square yard is accepted.

总疵点评分＊3600

The total grade points*3600

被查布匹实际长度＊实际布匹门幅(英寸)

the tested fabric length*the width of fabric(inch)

拒收标准：Ａ，一匹布疵点评分超过四十分．

unaccepted: A:the total deduction of one roller surpass 40 points.

Ｂ，整匹大货的标准疵点超过２０分．

B:the total deduction of bulk fabric on standarded defects surpass 20 points.

Ｃ，疵点连续出现在三米或以上，不论疵点评分多少．C:the continuous defects appeared than 3 meter or more no matter how much the deduction.

三、十分制检验：

the 10 points inspection system

1．经向疵点扣分法:

the warp defect deduction

1”以下扣1分 1 point deducted

1”——5”扣3分 3 point deducted

5”——10”扣5分5point deducted

10”——36”之间扣10分 10 point deducted

纬向扣分法:

the weft defect deduction

1”以下扣1分 1 point deducted

1”——5”扣3分 3 point deducted

5”——半门幅之间扣5分 5point deducted

半门幅以上上扣10分10 point deducted

疵点的评分原则：

The grade principle on defect:

A：同一码中所有经纬向的疵点扣分不超过10分．

the total deduction can not surpass 10 point on all warp and weft in the same yard.
