Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard uses redrafted Law Amendment uses ISO 15754.2009 "Paper and paperboard Z direction tensile strength determination." This standard and ISO 15754.2009 Main technical differences and their reasons are as follows. Information on normative references, this standard has been adjusted technical differences, in order to adapt our technical conditions, adjust the set As reflected in Chapter 2, "Normative references", the specific adjustments are as follows. • Modify with international standards of GB/T 450 instead of ISO 186 (see 7.1); • Use equivalent to international standards of GB/T 10739 replaced by ISO 187 (see 7.1). The standard proposed by China National Light Industry Council. The standard paper by the National Standardization Technical Committee (SAC/TC141) centralized. This standard was drafted.

1 Scope

This standard specifies a method for determining the Z tensile strength. This standard applies to paper and paperboard, not for corrugated cardboard. The standard paper weight range not explicitly defined, but when the basis weight of less than 60.0g/m2, it is possible to make double-sided adhesive paper Increased strength, the test results for reference only.

2 Normative references

The following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein Member. For undated references, the latest edition (including any amendments) applies to this document.

3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 Z to the z-direction And the direction perpendicular to the paper. 3.2 Z-tensile strength z-directionaltensilestrength Under the test conditions specified unit area of \u200b\u200bpaper or paperboard to Z can withstand the maximum tensile strength in kilopascals (kPa) represented. Principle 4 When using double-sided adhesive paste samples between two flat metal plate, apply some pressure to the sample, and maintained to a predetermined pressure between. Tension is applied to the use of a tensile tester samples along the Z-direction, within the prescribed loading time for the destruction of the sample, the instrument records through the entire stretch Maximum tensile process.

5 Test Equipment

5.1 tensile tester 5.1.1 pressing device can double-sided adhesive and sample test disc bonded together to keep the pressure 1.4MPa ± 0.1MPa. 5.1.2 tensile test apparatus is shown as the value of accuracy ± 2%. Note. The range is 1kN force measuring device is suitable. ......
