Standard ASTM E1118-95
1.1 This practice covers acoustic emission (AE) examination or monitoring of reinforced thermosetting resin pipe (RTRP) to determine structural integrity. It is applicable to lined or unlined pipe, fittings, joints, and piping systems.
1.2 This practice is applicable to pipe that is fabricated with fiberglass and carbon fiber reinforcements with reinforcing contents greater than 15 % by weight. 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.
1.5 This practice applies to examinations of new or in-service RTRP.
1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
