FZ/T32006—2033
This standard does not replace 2006 core hemp cutting (original code 2-2). The main changes of this standard are that the original single yarn, single yarn, and multi-ply yarn are divided into a series of products with the same grade as the original single yarn. The grade is changed to a low grade; the original single yarn strength and pain rate index is changed to single wire breakage end and single wire strength coefficient of variation index:
The original weight difference is tightened by .5%; the thickness of the book is only K)n thick section number "Xie Azhou".
The land of this standard is an attached document.
This standard is sponsored by China Construction Industry Association: This standard is the technical research center of Shanhu Forestry University. This standard is made by the Nanning Provincial Product Quality Supervision and Inspection Center. The drafters of this standard are: Bin Qiangzou, Jiang Wei, Wu Runjie, and Qie Zou Ying. The standard replaced by this standard is: FJ231282.FZ/T320061999.

Natural color yarn
EZ/T32006—2003
This standard specifies the product classification, requirements, inspection methods, inspection rules, marking, packaging, selection and storage, and quality of the ply yarn produced by replacing the warp sheets of the hemp long fiber yarn produced by the spinning machine. It is a standard for the inspection of the quality of the hemp yarn. 2 Normative references

4.4.1 The quality of hemp thread is determined by "wholesale\ The unit is stipulated to be the production volume of three small shifts of one variety per night as one batch. For those who produce frequently or in a single shift, the production volume of one shift is regarded as one batch. If there is a temporary single shift production, it can be included in this batch. The test is carried out according to the prescribed test period and various test methods, and the grade of the drug is evaluated according to the specific results. 4.4.2 The grade of the drug is divided into superior grade, first-class grade, second-class grade and second-class grade. 4.4.3 The grade of the drug in the forbidden area is evaluated based on single or multiple variable coefficient (V value), disc variable coefficient effect (V%) and crude drug content. When the grade of one item is different 4.4.4 When the difference between the strength of a product or the strength of a product exceeds the allowed range, the product shall be reduced by one level based on the original evaluation of the strength coefficient of variation (%) and the weight ratio coefficient of variation C (). If both items exceed the range, the product shall be reduced by one level only. 4.5 Requirements for the control of monthly deviations
The cumulative deviation of the inspection line should be strictly controlled according to the weighted average of the whole production of more than 15 products. It should be controlled within 5% or less.
