This standard adopts the former Soviet Union's "OCT3436--1969 "Fiber Paper Base Paper" in a non-equivalent manner. This standard replaces QB550-1981 "Fiber Paper Base Paper", and divides the original standard's five product numbers into Type 1, Type I, and Type II according to their uses, and adds some content such as inspection rules.
This standard implements (50±2)%rh., (23±1)℃ test atmospheric conditions. 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: Mudanjiang Hongqi Paper Factory. The main drafters of this standard: Guan Shengjin, Liu Yuqin. From the date of implementation of this standard, the former Ministry of Light Industry Standard QB550-1981 "Fiber Paper Base Paper" will be invalid. 383

Standard atmosphere for sample handling and testing of pulp, paper and paperboard 3.1 Steel paper base paper can be divided into three types according to its use: I, II and III. Type I is used for the manufacture of hard steel paperboard or soft steel paperboard for aviation components; Type I is used for the production of steel paper tubes; Type III is used for intermittent or continuous steel paper machines to produce steel paperboard, electrical insulation steel paperboard, high-strength steel paperboard, thick steel paperboard and sliver tube steel paperboard or reel steel paperboard. 3.2 The steel paper base paper is a roll paper with a roll diameter of 600mm~800mm or as specified in the contract. 3.3 The roll width is 800mm, 1500mm for type 1, 800mm for type 2, 1450mm, 1500mm, 1600mm for type Ⅱ or as specified in the contract. The width deviation shall not exceed ±3mm.
