GB/T 22874-2008Single-faced and single-wall corrugated fibre board -- Determination of flat crush resistance (English PDF)

Foreword

This revised standard adopts ISO 3035. 1982 "and the single-sided corrugated board flat crush strength determination." this standard and ISO 3035. 1982 as compared to the main differences are as follows.

--- International standards in Chapter 1, "scope" and Chapter 2, "Applications" merger of this standard in Chapter 1, "scope";

--- References to normative documents substituted with International Standard reference materials, and the ISO 3035 international standard referenced into with the corresponding national standards (Chapter 2 of this standard);

--- The flat crush tester parallelism deviation is less than "1.1000" to "1.2000" (this standard 4.1);

--- Increase the chart in Appendix A and single-sided corrugated board.

Appendix A of this standard is a normative appendix.

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. Exit Inspection and Quarantine Technology Center of Guangdong, China Pulp and Paper Research Institute, the National Quality Supervision, Inspection and paper center.

1 Scope

This standard specifies the determination method of manufacturing a corrugated cardboard box flat crush strength.

This standard applies to single-sided and corrugated board, does not apply to double corrugated cardboard.

2 Normative references

The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents.

Principle 3

Take a sample representative of the corrugated board, with compression tester consists of two parallel plates composed of a vertical surface of the specimen plus Pressure until the corrugated crushed so far, determine the maximum pressure per unit area of \u200b\u200bthe specimen subjected to kilopascals (kPa) represented.
