Bibliography

Defines a technical basis for developing quantitative, allowable flaw sizes and for setting acceptance/rejection limits for cylinders at the time of periodic inspection and testing based on the performance and mechanical properties of the cylinders.

The aim of this Technical Report is to establish a technical basis for developing quantitative, allowable flaw sizes and for setting acceptance/rejection limits for cylinders at the time of periodic inspection and testing based on the performance and mechanical properties of the cylinders.
