GB/T 6547-1998 "Corrugated fibreboard - Determination of thickness" specifies the method for determining the thickness of corrugated fibreboard, applicable to all types of corrugated fibreboard. Under a pressure of (20±0.5) kPa and a contact area of (10±0.2) cm², the distance between two parallel planes is measured using a thickness gauge at a speed of 2-3 mm/min. The standard clarifies sample handling, measurement points, and result calculation, with results expressed in millimeters accurate to 0.05 mm, providing a basis for quality control of corrugated fibreboard.
