## 4 Standard Test Data Analysis Waterproofing Performance Gradation
### Gradation Target Performance Evaluation Criteria  
This study, among test criteria of Table 3, based on \"Grade 5 Scale\" theory adopted in 2.2, excluded performance evaluation criteria (curve resistance performance, water pressure resistance performance, sink resistance performance and fatigue resistance performance) by qualitative evaluation (visual observation) inadequate for gradation and implemented gradation analysis on gradation 9 performance evaluation criteria (tensile strength and elongation ratio of tensile performance, tensile strength and elongation ratio of 60 \({}^{\circ}\)C temperature dependency performance, tensile strength and elongation ratio of \(-\)20 \({}^{\circ}\)C temperature dependency performance, peeling resistance performance of adhesion stability performance and adhesion performance) with applicable qualitative evaluation (mechanical measurement). Basic conditions for standard test data analysis are as in the following Table 3. \begin{table}
