Introduction
Interpretation of GB/T 11717—2018 National Standard for Papermaking Logs
Background and Significance of the Standard
GB/T 11717—2018 National Standard for Papermaking Logs was issued in 2018, replacing the previous GB/T 11717—2009 version. The standard was proposed by the State Forestry and Grassland Administration and is managed by the National Technical Committee for Timber Standardization.
Main Technical Changes in the Standard
- Scope Modification:The scope of application of papermaking logs is more clearly defined.
- Addition of Terms and Definitions:Added relevant terms for easier understanding and implementation.
- Dimension and Tolerance Specifications:The requirements for gauge length and gauge diameter are refined to improve the accuracy of the standard.
- Defect tolerance adjustment:Optimized the control requirements for log defects to ensure product quality.
Comparative analysis of standard frameworks
| Standard dimensions | Requirements of the 2009 version | Requirements of the 2018 version |
|---|---|---|
| Scope | It is relatively general and does not define the applicable areas in detail. | It is clearly applicable to the production, circulation and supervision and inspection of logs for papermaking. |
| Terms and definitions | Not systematized, and some terms are vague. | Added a new terminology and definition chapter to ensure consistency in standard implementation. |
| Dimensions and Tolerances | The range of gauge length is limited, and the tolerance requirements are not clear. | The classification and tolerance control of gauge length and gauge diameter are refined. |
Implementation Suggestions
1. Sampling and inspection methods:Strictly follow the provisions of GB/T 17659.1 and GB/T 144 to ensure the scientific nature of sampling and inspection.
2. Timber volume calculation:GB/T 4814 is used for timber volume calculation within the standard range. If it exceeds the range, refer to the papermaking log volume table in Appendix A.
3. Defect control: Strictly control the use of rotten wood and burnt wood to ensure that product quality meets the requirements of papermaking process.
