Ring crush strength of paper or paperboard refers to the edge of the ring until the specimen under pressure when I crush can withstand the maximum compressive force in kN / m representation. Abroad often use RCT showing ring crush strength, the unit with Ibf / in Fig. Since corrugated paper corrugated board production lines pressed into corrugated cardboard, the corrugated paper and corrugated transverse direction parallel, while corrugated cardboard cardboard box, which is usually the direction of compression corrugated direction, which is transverse corrugated paper, therefore, in the corrugated paper product standard only provides lateral pressure ring, at the same time, since the ring crush strength of corrugated base paper with the quantitative increase and increase, in order to eliminate the quantitative impact, to facilitate comparison of different quantitative corrugating medium, the standard provision is transverse ring crush index. Ring crush index divided by the average ring crush strength obtained quantitatively to N * m / g expressed. Ring crush strength was measured according to GB / T 2679.8-1995 "Paper and cardboard ring crush strength determination" to.
