Summary: This standard specifies the use of a constant tensile speed 100mm/min test instrument measuring tensile strength, fracture elongation, tensile energy absorption and tensile stiffness method. And provides tensile index, tensile energy absorption index, calculated tensile stiffness index and elastic modulus. Compared with other properties of tensile strength, tensile stiffness measurement accuracy requirements for higher elongation. If a lower accuracy of the measurement of the elongation. Tensile stiffness values ??obtained would be inconsistent with this standard. This standard applies to all paper and paperboard, including paper high elongation, such as crepe paper and stretch of sack paper. This standard does not apply to low-density paper, such as paper and tissue products.

Foreword

This revised standard adopts ISO 1924-3.2005 Determination of tensile strength "paper and paperboard - Part 3. Constant rate of elongation method (100mm/min) ". This standard and ISO 1924-3.2005 as compared to the main differences are as follows. --- Normative references to international standards in the ISO standard document references into its corresponding national standard, GB/T 450 paper And to take samples and specimens of vertical and horizontal to the board, positive and negative determination (GB/T 450-2008, ISO 186.2002, MOD); --- International Standard ISO document standard will be referenced in the normative references converted to its corresponding national standard, GB/T 451.2 Paper and paperboard quantitative determination (GB/T 451.2-2002, eqv ISO 536.1995); --- International Standard ISO document standard will be referenced in the normative references converted to its corresponding national standard, GB/T 10739 paper, paperboard and pulp sample processing and testing standard atmospheric conditions (GB/T 10739-2002, eqv ISO 187.1990). 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. Sichuan Changjiang Paper Instrument Co., Ltd., China Pulp and Paper Research Institute, the National Quality Supervision, Inspection and paper center. The main drafters of this standard. Yin Primula. Paper and board Determination of tensile strength

1 Scope

This standard specifies the use of 100mm/min constant tensile speed test instrument measuring tensile strength, elongation at break, tensile energy The method of absorption and tensile stiffness, and provides formulas tensile index, tensile energy absorption index, tensile stiffness index and elastic modulus. Compared with other tensile strength properties, tensile stiffness measurement accuracy of elongation demanding. Using a lower accuracy into Determination of the amount of the line elongation, tensile stiffness values \u200b\u200bobtained are inconsistent with this standard. This standard applies to all paper and cardboard, including paper high elongation, such as crepe paper sack and extensor. This standard does not apply to low-density paper such as toilet paper and its products.
