1.1This standard method describes the technology and testing procedures that can be used to detect seal defects in the size range of 1 mm and characterize seal quality in a variety of packaging styles using airborne ultrasound technology.

1.2This test method does not purport to be the only method for measurement of seal quality.

1.3Heat seals and other package components can be tested in flexible, semi-rigid and rigid packages. Only the precision and bias for flexible package seals were evaluated in a recent ILS included in the method. The precision and bias for any specific package needs to be individually determined.

1.4On-line, real time inspection of seals can be considered particularly in the L-Scan mode.

1.5This method provides a non-destructive, quantitative, non-subjective approach to flexible package seal inspection.

1.6The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.7This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.8This 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.
