QB/T 2203—1996
This standard confirms QB162—1979 "Drawing Paper", and its contents are mainly changed as follows: It is written according to GB/T1.1--1993 "Guidelines for Standardization Work Unit 1: Rules for Drafting and Presentation of Standards Part 1: Basic Regulations for Standard Writing".
The atmospheric conditions of 23℃ and 50% relative humidity are adopted, so the physical indicators of breaking length and folding endurance are adjusted accordingly, and the technical requirements are equivalent to the original standard level.
The first dustiness is based on the area method specified in GB/T1541—1989 "Determination of the Dustiness of Paper and Paperboard", which is basically consistent with the standard level of the original standard length method.
The method specified in GB/T28281987 "Batch Inspection Count Sampling Procedure and Sampling Table (Applicable to Continuous Batch Inspection)" is adopted in the inspection rules.
The technical indicator level is changed from No. 1 and No. 2 to B and C. This standard was proposed by the Food Papermaking Department of the China Light Industry Association. This standard is under the jurisdiction of the National Papermaking Standardization Center. The drafting unit of this standard: Baoding Banknote Paper Factory. The main drafters of this standard: Cao Xiuhen and Qi Yulan. From the date of implementation of this standard, the former Light Industry Department Standard QB162-1979 "Drawing Paper" will be invalid. 411
