Design based on ASME PCC

The ASME PCC-2 approach is similar to ISO 24815 with only minor differences that

In ASME-PCC2, the allowable strain for repair laminate is slightly different from the ISO standard. ASME values are as given in Table 10.4. 

In the design of through-wall defects, the following differences are apparent. Firstly, the service factor, /perf, is set to 0.333 or as per Table 10.5 if the performance data are available. This factor has also been used instead so ASME does not define a different derating
