Foreword

This document complies with the provisions of GB/T 1:1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents" Drafting: This document replaces GB/T 10739-2002 "Standard Atmospheric Conditions for Handling and Testing of Paper, Board and Pulp Samples" and is consistent with Compared with GB/T 10739-2002, in addition to structural adjustments and editorial changes, the main technical changes are as follows: a) Added terms and definitions for calibration points and monitoring points (see 3:3, 3:4); b) Added sample discard conditions (see 5:2); c) Added “testing” requirements (see 6:3); d) Added stipulations on the test date in the test report (see Chapter 7); e) Changed the requirements for constant temperature and humidity laboratory test equipment, technical indicators and test methods (see Appendix B,:2002 version Appendix A): This document is modified to adopt ISO 187:2022 "Standard atmosphere and control procedures and tests for temperature and humidity treatment and testing of pulp, paper and paperboard" Sample temperature and humidity treatment method: Compared with ISO 187:2022, this document has many structural adjustments: See the comparison list of structure number changes between the two files: Appendix A: The technical differences between this document and ISO 187:2022 and their reasons are as follows: a) Incorporate the content of Note 1 into the definition of temperature and humidity treatment to make the definition more complete (see 3:2); b) Added terms and definitions of calibration points and monitoring points to enhance understanding of technical content (see 3:3, 3:4); c) Delete the provisions that tropical countries can also use (27±1)℃ and relative humidity (65±2)% in standard atmospheric conditions to adapt to our country Technical conditions (see 5:1 of ISO 187:2022); d) Delete the processing requirements for laboratory paper sheets prepared according to ISO 5269-1 and ISO 5269-3, which are already relevant in GB/T 24324 Requirements (see Chapters 5 and 6 of ISO 187:2022); e) The pretreatment requirements have been changed to adapt to my country’s technical conditions (see 6:1 of ISO 187:2022); f) Appendix B has been changed, adding technical requirements for constant temperature and humidity laboratory test instruments, laboratory technical requirements, temperature, humidity, and wind conditions: Test methods for speed, pressure difference, noise and other parameters to improve the operability of control, calibration and monitoring of constant temperature and humidity laboratories (see Appendix B): The following editorial changes have been made to this document: a) The name of the standard is changed to "Standard Atmospheric Conditions for Handling and Testing of Paper, Paperboard and Pulp Samples"; b) Changed the description of the moisture content of the sample entering the equilibrium state (see Chapter 4, Chapter 4 of ISO 187:2022); c) Changed the note of 6:2 (see 6:2, 6:2 of ISO 187:2022); d) Deleted Appendix B (informative) relationship between temperature and relative humidity (see Appendix B of ISO 187:2022); e) Added Appendix A (informative) for comparison between this document and ISO 187:2022 structure numbers (see Appendix C); f) Added Appendix C (informative) laboratory structure and equipment reference requirements (see Appendix B): Please note that some content in this document may be subject to patents: The publisher of this document assumes no responsibility for identifying patents: This document is proposed by China Light Industry Federation: This document is under the jurisdiction of the National Paper Industry Standardization Technical Committee (SAC/TC141): This document was drafted by: Tianjin Boya Guangming Environmental Equipment Technology Development Co:, Ltd:, Zhejiang Kane New Materials Co:, Ltd:, China Pulp Papermaking Research Institute Co:, Ltd:, Zhongqing (Jinjiang) Sanitary Products Research Co:, Ltd:, Zhongqing Paper Products Inspection and Certification Co:, Ltd:, Eddie Fubaix (Heavy Products) Qing) Technology Co:, Ltd:, Shandong Bohui Paper Co:, Ltd:, Zhejiang Zhongxin Environmental Protection Technology Group Co:, Ltd:, Guangda Paper Products (Zhongshan) Co:, Ltd:, Guoteng Colored Paper Products (Heshan) Co:, Ltd: The main drafters of this document: Shen Zhenhuang, Fu Hongda, Li Xin, Liu Junjie, Wang Xinting, Wen Jianyu, Li Dafang, Tao Huixian, Mao Dongsheng, Sun Jianjun, Teng Bubin, Huang Yaodong, Huang Yaoxing: The previous versions of this document and the documents it replaces are as follows: ---First published as GB/T 10739-1989 in 1989, first revised in:2002; ---This is the second revision: Paper, cardboard and pulp Standard atmospheric conditions for specimen handling and testing

1 Scope

This document specifies the standard atmospheric conditions for temperature and humidity treatment and testing of paper, paperboard and pulp prior to testing: This document applies to the handling and testing of paper, board and pulp specimens:

2 Normative reference documents

This document has no normative references:

3 Terms and definitions

The following terms and definitions apply to this document: 3:1 relativehumidityrelativehumidity Under the same temperature and pressure conditions, the ratio of the actual water vapor content to the saturated water vapor content in the atmosphere: Note: Expressed in percentage: 3:2 Temperature and humidity treatmentconditioning The process of achieving moisture content equilibrium between the sample and the atmosphere at specified temperature and relative humidity (3:1): Note: When the interval between the two previous weighings is more than 1 hour, and the difference in the weighed mass of the sample is not greater than 0:25% of the previous weighed mass of the sample, the sample is considered to be in contact with the atmosphere: balance between conditions: 3:3 calibrationpoint calibrationpoint The positions of temperature and humidity sensors required to be arranged in the constant temperature and humidity laboratory during the calibration process: 3:4 monitorpointmonitorpoint The required position of temperature and humidity sensors during use of a constant temperature and humidity laboratory:

4 Principles

The sample is exposed to the specified atmospheric conditions of constant temperature and humidity, so that the adsorption and release of moisture by the sample reaches a relatively stable state: At this time, the sample The specimen has reached equilibrium with this atmospheric condition:

5 Standard atmospheric conditions

5:1 The test standard atmospheric conditions used for paper, cardboard and pulp should be temperature (23:0±1:0)℃ and relative humidity (50:0±2:0)%: 5:2 Measure the atmospheric conditions of the laboratory according to Appendix B: If all test results are within the allowable limits, the atmosphere should be considered
