Foreword
This standard is GB/T 10340-1989 "Paper and paperboard filtration rate assay" amendments.
This standard replaces GB/T 10340-1989.
This standard compared with GB/T 10340-1989, the main changes are as follows.
--- To increase the content of the normative references (Chapter 2 of this edition);
--- Increased reagent (Chapter 5 of this edition);
--- Increasing the drainage rate results rounding (edition 9.3);
--- The purified water temperature from 20 ℃ revised to 23 ℃ (this version 8.2.1);
--- Modified test procedure (Chapter 8 of this edition).
The standard proposed by China National Light Industry Council.
This standard by the National Standardization Technical Committee of the paper industry.
This standard was drafted. Product Quality Supervision and Inspection Institute of Henan Province, China Pulp and Paper Research Institute.

This standard replaces the standards previously issued as follows.
--- GB/T 10340-1989.
This standard by the National Standardization Technical Committee is responsible for interpreting the paper industry.
Paper and paperboard filtration rate
1 Scope
This standard specifies the method for determination of paper and paperboard filtration velocity.
This standard applies to a certain wet strength filter paper and cardboard, not apply to the processing of resin, its surface is not hydrophilic or incomplete pro-
Water filter paper and cardboard.

3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
When the pressure is on both sides of the sample 1kPa (ie 100mm water column) when, 100mL of water through a diameter of 35.7mm (area 10cm2) test
Like the time required in s.
3.2
When the pressure is on both sides of the sample 1kPa (ie 100mm water column), the water unit time through unit area of \u200b\u200bspecimen to mL/(cm2 · s)
FIG.
Principle 4
In 1kPa (ie 100mm water column) constant pressure, purified water 100mL (23 ± 1) ℃ through 35.7mm diameter sample required
Time, you can evaluate the relative performance of the water treatment filter paper and paperboard.
