Foreword
This standard is a revision of JB/T5419--91 "Plastic Extrusion Flat Film Flat Yarn Auxiliary Machine". Compared with JB/T5419-91, the main technical content of this standard has been changed as follows: the terminology part of the original standard has been removed; Necessary additions and modifications have been made to the test methods and inspection rules. This standard replaces JB/T5419-91 from the date of implementation. This standard was proposed and managed by the Plastic Machinery Branch of the National Technical Committee for Standardization of Rubber and Plastic Machinery. The units responsible for drafting this standard: Changzhou Plastic Machinery Factory, Gansu Light Industry Machinery Factory, Dalian Plastic Machinery Research Institute. The main drafters of this standard: Wu Xingqin, Yi Dandan, and Li Xianglan. This standard was first released on July 22, 1991. Scope

5.1 Test methods
5.1.1 Sampling
When the product is shipped out of the factory for inspection, a full inspection should be carried out. Sampling inspection is carried out during type test, and one unit is selected at a time. If any of the 2
JB/T5419-2000
items among the inspection items is unqualified, another unit should be randomly inspected. If there are still unqualified items, the type test will be judged as failed. 5.1.2 Detection of production speed
Under stable process conditions, use a tachometer to measure the linear speed of the first-level traction reel before winding. 5.1.3 Detection of noise of the whole machine bzxz.net
According to the position shown in Figure 1, measure 6 points at a distance of 1m from the machine and a height of 1.5m, and take the average value. Roll system
