The suitability of these procedures must be demonstrated before they are used for piping that is constructed with other reinforcing materials.

1.3 This practice is applicable to tests below pressures of 35 MPa absolute (5000 psi

1.4 This practice is limited to pipe up to and including 0.6 m (24 in.) in diameter. Larger diameter pipe can be examined with AE, however, the procedure is outside the scope of this practice.
