CONTAINED IN VOL. 03.03, 2017 Specifies guidelines for acoustic emission (AE) examinations of new and in-service aboveground storage tanks of the type used for storage of liquids.

1.1This practice covers guidelines for acoustic emission (AE) examinations of new and in-service aboveground storage tanks of the type used for storage of liquids.

1.2This practice will detect acoustic emission in areas of sensor coverage that are stressed during the course of the examination. For flat-bottom tanks these areas will generally include the sidewalls (and roof if pressure is applied above the liquid level). The examination may not detect flaws on the bottom of flat-bottom tanks unless sensors are located on the bottom.

1.3This practice may require that the tank experience a load that is greater than that encountered in normal use. The normal contents of the tank can usually be used for applying this load.

1.4This practice is not valid for tanks that will be operated at a pressure greater than the examination pressure.

1.5It is not necessary to drain or clean the tank before performing this examination.

1.6This practice applies to tanks made of carbon steel, stainless steel, aluminum and other metals.

1.7This practice may also detect defects in tank linings (for example, high-bulk, phenolics and other brittle materials).

1.8AE measurements are used to detect and localize emission sources. Other NDT methods may be used to confirm the nature and significance of the AE indications (s). Procedures for other NDT techniques are beyond the scope of this practice.

1.9Examination liquid must be above its freezing temperature and below its boiling temperature.

1.10Superimposed internal or external pressures must not exceed design pressure.

1.11Leaks may be found during the course of this examination but their detection is not the intention of this practice.

1.12Units—The values stated in either SI units or inch-pound units are to be regarded as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standards.

1.13This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 8.

1.14This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
