Introduction
September 2003, the State Council approved the "Cotton Quality Inspection Reform Programme" (hereinafter referred to as "the program"), will establish clear instrumentation
Inspection system as a future development direction of the cotton quality inspection system in China, and clearly it requires the development of suitable instruments of inspection of cotton
Color map and its application software. After several years of research and experimental verification for serrated processed color grading system has been basically established, but
Not yet suitable for roller cotton. Currently, there is still some cotton circulation market share of the roller cotton, and the cotton textile industry, there is off to roller cotton
Outlook needs, so the need to retain the original roller cotton grade indicators and their testing methods and so on. However, in a standard while retaining the product
Grade, color grade two kinds of quality indicators and test methods, is not conducive to cancel grade indicators specified in the standard will result in a grade at the same time, the color
Level, resulting in the standard style, content chaos. Agreed by the relevant departments, the National Standard GB 1103-2007 "Cotton Lint
Score. Paper roll processing Upland ", where jagged upland cotton processing using color grading index system, roller processing Upland grade index remained body
system. This document is in this context of the revision.

5.2.1 acquisition of seed cotton samples
The acquisition of seed cotton adopt a multi-point random sampling method.
1t and below to extract a sample; more than 1t, 5t and the following extract three samples; 5t above, 10t and below selected five samples;
10t drawn above 7 samples. Each sample was less than 1.5kg.
5.2.2 seed cotton big stack sampling
Big stack of seed cotton taken in different directions, multi-point, multi-random sampling method, sampling depth of not less than 30cm.
In the stack unit sampling, sample quantity. 10t and below the big smoke stack 3 samples; 10t or more, 50t and below the big stack pumping five samples;
50t over big stack pumping seven samples. Each sample was less than 1.5kg.
5.3 Sampling lint bales
5.3.1 sampling batches
5.3.1.1 Test sample weight. impurity rate sampling every 10 packs (less than 10 packs of 10 packet count) 1 package pumping, compressed sample from each bale
After opening the package surface, remove the surface layer of cotton bales and then uniformly sampled to form a total weight of less than 600g trash content testing laboratory samples.
Beyond the bale from the inner to the outer layer of 10cm ~ 15cm bale at the extraction test sample regain about 100g, loaded into a sealed container seal, shape
To regain inspection lot like.
5.3.1.2 sampling quality inspection. 10 per pack (10 packs of less than 10 by packet count) 1 package pumping, compression face open packet from each bale after sampling,
Remove the surface layer of cotton bales, complete decimation sample into pieces of about 300g, the formation of quality inspection lot like.
5.3.1.3 quality inspection and test weight at the same time, the sample can be extracted from the impurity rate quality inspection lot samples, the samples according to regain
5.3.1.1 regulations.
5.3.1.4 lint bales sample prohibited in Baotou.
5.3.1.5 into packets before test sample. cotton processing units can be sampled from the total set of cotton the main channel viewing window. In the bulk of cotton bales process
Per 10 packs (less than 10 packages of 10 count package) sampled once. About 300g each randomly selected samples for moisture regain, grade, length, horse
Cloning value and impurity rate test. Every time then randomly selected sample of not less than 2kg, after the merger of the opposite sex as a batch of cotton fiber content inspection
Lot sample.
5.3.2 packet by packet sampling
5.3.2.1 package by sampling only for Ⅰ type bale.
5.3.2.2 using a special sampling apparatus, in the middle of each of the two surfaces compressing bales, respectively, cut length 260mm, width 105mm or
124mm, weight less than 125g of sample cut.
5.3.2.3 When sampling, each sample was cut in half by the average level, which corresponds to half of a sample cut outside and another bale
Cutting a sample corresponding to the inside of the bales into one half of the test sample, the remaining two and a half combined to form cotton processing units remain
kind. Cotton samples should be taken to maintain the original cut shape, size, i.e., the sample is rectangular and flat chaos.
5.3.3 heterosexual cotton fiber sample when trading
Cotton transaction requires transaction costs for bulk package heterosexual fiber lint quantitative or qualitative examination of the transaction by the relevant parties indeed
Set specific sampling method and number of samples.
