Quality Grading of Corrugated Machine Products
(Internal Use)
This standard specifies the quality grade, test method, sampling and evaluation method of corrugated machine products. JB/T53048-1999
Replaces JB/T53048-92
This standard applies to corrugated machine products specified in JB/T7542-1994 "General Technical Conditions for Corrugated Machines". 2 Referenced Standards
The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard is published, the versions shown are valid. All standards will be revised, and parties using this standard should explore the possibility of using the latest version of the following standards. JB/T7542—1994 General Technical Conditions for Corrugated Machines 3 Product Quality Grades
Corrugated machine products are divided into two grades: qualified products and first-class products according to their quality level and use value. 3.1 In addition to complying with the provisions of JB/T7542, the project indicators and requirements of each assessment grade shall also comply with the provisions of Table 1 and 3.2.
Assessment items
Corrugated paper quality
Upper corrugated roller to lower corrugated roller
Axis parallelism error
Corrugated roller tooth surface roughness
Corrugated roller life
Working noise
Effective amplitude ≥1500mm
Effective amplitude <1500mm
E-type corrugated
Main parts and main items qualified rate%
3.2 The structural level of the corrugator is classified according to the following contents: Product quality grade
Qualified products
Corrugations are evenly hooked and straight, without obvious
reverse corrugation, cracks, folds, etc.
≥10×10*
First-class products: the temperature of the corrugated roller is automatically controlled and heat-insulated. 4 Test method
Perform according to the test method specified in JB/T7542. Approved by the State Machinery Industry Bureau on December 30, 1999
Corrugation is uniform and straight, without inverted corrugation,
breakage, folding, etc.
≤012
≤008
≤Q06
≥1.5×104
Implemented on June 1, 2000
5 Sampling and evaluation methods
5.1 Sampling method
Product sampling shall be carried out in accordance with the provisions of JB/T7542. Evaluation method
JB/T530481999
To evaluate the product quality grade, it must meet the index requirements of all assessment items of the grade, or the grade shall be determined according to the lowest index achieved. 2wwW.bzxz.Net
