ASTM F3004-13e1

1.1 This 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.

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

1.3 Heat 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.

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

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

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

1.7 This 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.
