ASTM E515 : 11

Standard Practice for Leaks Using Bubble Emission Techniques

Standard Details

1.1 This practice covers procedures for detecting or locating leaks, or both, by bubble emission techniques. A quantitative measure is not practical. The normal limit of sensitivity for this test method is 4.5 × 10⁻¹⁰ mol/s (1 × 10⁻⁵ Std cm³/s).

1.2 Two techniques are described:

1.2.1 Immersion technique, and

1.2.2 Liquid application technique.

Note 1—Additional information is available in ASME Boiler and Pressure Vessel Code, Section V, Article 10-Leak Testing, and Guide E479.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 This standard does not purport to address 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.
