| Failure probability classification | Score value |
| 1 | ＜88 |
| 2 | 88～130 |
| 3 | 130～214 |
| 4 | 214～806 |
| 5 | ＞806 |
Further, using failure consequence grade as horizontal ordinate, and with failure probability grade for ordinate, failure probability and failure consequence can be divided into different brackets by the order of severity, form a risk Metrics, as shown in Figure 3.In figure 3, failure probability grade 1 to 5 grades represents that probable value increases successively, failure consequence grade A to E represents that consequence is more and more serious, value-at-risk is also divided into five risk class according to Fig. 3, correspond to low-risk district respectively and (comprise the A1 region in Fig. 3, B1 region and A2 region), medium to low-risk district (comprises the A3 region in Fig. 3, B2 region and B3 region), apoplexy danger zone (comprises the A4 region in Fig. 3, B4 region, C1 region, C2 region, C3 region, D1 region and D2 region), medium or high risk district (comprises the A5 region in Fig. 3, B5 region, C4 region, C5 region, D3 region, D4 region, E1 region and E2 region) and high risk area (comprise the D5 region in Fig. 3, E3 region, E4 region and E5 region).When the failure consequence assessment result of a certain uphole equipment to be assessed and failure probability fall into certain position of matrix, the risk class using the value-at-risk of this position as this uphole equipment to be assessed.
If according to risk class arrangement inspection or the maintenance of uphole equipment to be assessed, then in Fig. 3 lower left corner low-risk region due to occur failure probability low, failure consequence is not serious, failure risk is also low, when a certain uphole equipment to be assessed falls into this region, does not generally need to take measures; If fall into medium or high risk or high risk zone, then this uphole equipment to be assessed should as maintenance or the key object checked.To the process of risk, can implement by the measure be shown in Table 3.
