Paper smoothness tester

Implementation standards:

ISO 5627 Paper and board - Determination of smoothness (Buick method)

GB/T 456 "Paper and board smoothness determination (Buick method)"

Scope of Application:

This instrument is designed for determining the smoothness of paper and board materials according to the Bekk principle. The test involves placing a sample of paper or board against a highly polished glass surface under a controlled clamping pressure. A vacuum is then applied to the space between the paper and the glass plate, and the time taken for a specific volume of air to leak across the paper surface and under the clamping ring is measured. This air leakage time is the indicator of smoothness. The tester is widely used in:

Paper and board manufacturing for quality control and process optimization.

Printing industry to assess the suitability of paper for various printing processes.

Research and development laboratories studying the surface properties of paper and other sheet materials.

Quality inspection centers verifying product specifications.

The instrument is suitable for measuring the smoothness of a wide range of paper and paperboard grades.

Product Advantages:

Measures Key Surface Property: Quantifies smoothness, a fundamental characteristic affecting print quality, ink lay, and coating application.

Standard Compliant (Bekk Method): Operates according to internationally recognized Bekk method standards (ISO, GB, TAPPI).

Quantitative Measurement: Provides an objective numerical value for smoothness (in seconds).

Multiple Measuring Ranges: Offers different time ranges and vacuum container volumes to accommodate materials with varying degrees of smoothness, from very rough to very smooth.

High Timing Accuracy: Provides precise measurement of the air leakage time.
