Preface: This standard equate the ISO2759:2001 "the determination of cardboard burst degrees". Editorial revision on this standard only on the technical content is exactly the same. This standard is to the GB/T1539-1989 "measurement of cardboard burst degrees of revision. This standard GB/T1539-1989 instead. This standard Accurate compared with GB/T1539-1989 main changes are as follows: - increases preface; - terms and definitions for explanation; - according to the use of the instrument performance, will be not less than 690 kpa 5.1 clamping system of clamping force is changed to 700 kpa to 1200 kpa scope; - 5. 2 film of the relatively fixed film clip about this surface low 4.7 mm changed to about 4.7 mm; - 5.4 instead of pressure gauges, pressure measurement system using the limited to the bourdon tube type pressure gauge; - appendix D, explains the dynamic calibration. The appendix A of this international standard, appendix B, attached Record and appendix D are normative appendix C. This standard put forward by China light industry federation. This standard by the national paper industry standardization technical committee to review. This standard drafting unit: China academy of pulp. The main drafter of this standard: Zhang Qingwen, chun-chieh liu. All previous releases of this standard replaced standards as follows: GB/T1539-1961, GB/T1539-1979, GB/T 1539-1989 Paperboard--Determination of bursting strength. This standard entrust the national paper industry standardization technical committee will be responsible for the explanation.   
Description:The provisions of this standard to increase the hydraulic pressure is measured in cardboard burst degree method.
this standard applies to burst degrees of all the cardboard 350 kpa to 5500 kpa (including the corrugated cardboard and cardboard).
instead of this standard gb/t 1539-1989.
this standard equivalent to iso 2759:2001. "the determination of cardboard burst degrees."
editorial revision on this standard only on the technical content Exactly the same.
this standard and gb/t 1539-1989 compared with the main changes are as follows:
