Machinery Industry Standard of the People's Republic of China JB/T53080-1999 Plastic extrusion rotary shoemaking machine Product quality classification (Internal use) Published on December 30, 1999 National Bureau of Machinery Industry Implementation on June 1, 2000 JB/T53080—1999 This standard is a revision of JB/T5308093 "Product Quality Classification of Plastic Extrusion Rotary Shoemaking Machine". During the revision, the original standard was edited and the main technical content remained unchanged. This standard replaces JB/T53080—93 from the date of implementation. This standard was proposed and managed by the National Technical Committee for Rubber and Plastic Machinery Standardization, the Plastic Machinery Standardization Sub-Technical Committee. The responsible drafting unit of this standard: Hubei Echeng General Machinery Group Corporation. The main drafters of this standard are Zhou Hanbo and Chen Donglin. 1 1 Scope Machinery Industry Standard of the People's Republic of China Plastic extrusion rotary shoemaking machine Product quality classification (Internal use) JB/T53080-1999 Replaces JB/T53080-93 This standard specifies the quality grade, test method, sampling and evaluation method of plastic extrusion rotary shoemaking machine products. This standard applies to the product quality classification of plastic extrusion rotary shoemaking machine (hereinafter referred to as shoe machine) specified in JB/69291993 "Plastic extrusion rotary shoemaking machine". 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/T69291993 Plastic extrusion rotary shoemaking machine 3 Product quality level Shoemaking machine products are divided into three levels according to their quality level and use value: qualified products (capable of producing flat-heeled cloth shoes), first-class products and superior products (capable of producing ordinary travel shoes). In addition to complying with the provisions of JB/T6929, the assessment items and index requirements of each level of shoemaking machine products shall also comply with the provisions of Table 1. Table 1 Assessment index Product quality level Assessment items Rated output Shoe mold locking force Shoe plant locking force Unit consumption index Test method KW/(pair/h) dB (A) Product test method shall comply with the provisions of GB/T6929. Approved by the State Machinery Industry Bureau on December 30, 1999Qualified products (flat shoes)≥100≥110 (ordinary travel shoes)Superior products≥120 2000-06-01 Implementation5 Sampling and evaluation methodsJB/T5308019995.1 The sampled products must be batch products that have passed the inspection of the manufacturer's inspection department and are not unpacked at the user's place or have been put into storage. The sample for random inspection shall not be less than 2 sets. All test items shall be tested and evaluated at one time to determine the product quality grade. The product must meet the technical requirements of all assessment items of the grade. Otherwise, the grade shall be determined according to the lowest indicator achieved5.2 Machinery industry standards tt||Plastic extrusion rotary shoemaking machine Product quality classification (for internal use) JB/T53080—1999 Published and issued by the China Academy of Mechanical Science Printed by the China Academy of Mechanical Science (No. 2 Shouti South Road, Beijing, zip code 100044)* Format 880×1230Www.bzxZ.net 1/16 Printing sheet 1/2 Number of words 6000 First edition in April 2000 Print number 1-500 First printing in April 2000 Price 1000 yuan 99-1480 Mechanical Industry Standard Service Network: http/kvwwJB.ac.cn6660800 Tip: This standard content only shows part of the intercepted content of the complete standard.
