"There are other measurement capabilities that the standard has yet to explore. "F3004 may be further developed as sensory capabilities improve," says Stauffer. We have shown (Amir, 2007) that detectability of a given flaw decreases with its distance from an access tube. RILEM/Testing of Concrete by the Ultrasonic Pulse Method. Modern ultrasonic equipment can without difficulty cover a distance of at least four meters between emitter and receiver, but the usefulness of such a large spacing is doubtful. ASTM C 597-83 (91) Standard Test Method for Pulse Velocity Through Concrete. Stauffer says that manufacturers, regulatory bodies and laboratories will all find F3004 useful, especially as the shift is being made toward more quantitative test measurement solutions, particularly in the medical device industry.Īll interested parties are invited to take part in the standards developing activities of F02.40. The following eight standards are analyzed in this paper: BS 1881: Part 203: 1986 Testing Concrete- Recommendations for measurement of velocity of ultrasonic pulses in concrete. The technology described in F3004 is used to image seals and evaluate variances across the entire active seal area to ensure even temperature and pressure distribution during the sealing process. "Any flexible packaging operation that applies a final seal to a pouch can deploy an airborne ultrasound sensor on the line for high speed 100 percent seal quality assurance," says Stauffer.Īirborne ultrasound sensors can be integrated into production lines or a stand-alone system can be installed just after a seal station to confirm seal quality. However, airborne ultrasound offers a faster and more reliable assessment of package seal quality based on a quantitative measure. Typically, device manufacturers have used manual-visual inspection as the preferred test for porous barrier packaging. "It is one of the few solutions that nondestructively measures the physical integrity and quality of a flexible packaging seal."Īccording to Stauffer, medical device packaging requires a high level of seal integrity assurance. "Airborne ultrasound has been on the market for over a decade now and has a very specific niche in the flexible packaging industry," says Oliver Stauffer, chief operating officer, PTI Inspection Systems, and an F02 member.

F3004, Test Method for Evaluation of Seal Quality and Integrity Using Airborne Ultrasound, was developed by Subcommittee F02.40 on Package Integrity. Now ASTM International Committee F02 on Flexible Barrier Packaging has developed a new standard for a relatively new packing technology, airborne ultrasound. Proper packaging procedures are an important aspect of any industry.
