Introduction
1. Standard Overview
GB/T 43605-2023 "Method for Drawing Atmospheric Corrosion Maps" specifies the method for drawing regional atmospheric corrosion maps based on atmospheric environmental corrosion tests and data, including general provisions, drawing process, drawing data preparation, geospatial interpolation model construction and other technical requirements.
2. Comparison of standard frameworks
| Standard dimensions | GB/T 43605-2023 | Comparison with international standards |
|---|---|---|
| Scope | Applicable to atmospheric corrosion evaluation and regional distribution mapping of metal materials | Consistent with NACE international standards |
| Technical requirements | Must comply with national surveying and mapping standards, including legends, color codes and other specifications | In line with relevant ISO standards |
| Implementation requirements | Data acquisition and interpolation model construction must be verified | Support dynamic environmental change analysis |
3. Interpretation of key technical points
Case: Application of geographic spatial interpolation model
Take the inverse distance weighted method as an example. This method is based on the 'first law of geography' and realizes the assignment of blank areas in the data through weight calculation. The formula is as follows:
\[ Z_{0}=\sum_{i=1}^{n} Z_{i} \lambda_{i} \]Wherein, the weight of the control point is calculated as:
\[ \lambda_{i}=\frac{\frac{1}{d_{i}^{T}}}{\sum_{i=1}^{n} \frac{1}{d_{i}^{T}}} \]4. Implementation Suggestions
Data acquisition and verification: Ensure the accuracy and completeness of the data source. It is recommended to use natural exposure tests to obtain corrosion rates.
Interpolation model optimization: Select the optimal model according to regional characteristics, and evaluate the error through methods such as leave-one-out cross validation.
Graphic design: Reasonably select color scales and grading to ensure that the legend is clear and easy to understand and complies with the printing specifications of GB/T 14511.
