What specific or packaging material are you testing? astm d3078 pdf 2021
A practical industry recommendation is to use approximately 70% of the package's failure pressure as the working vacuum level. For example, if a package fails at –70 kPa, a practical test level would be around –50 kPa.
Manufacturers offering ASTM D3078-compliant equipment include MOCON (Dansensor Lippke series), Labthink (C660B series), Presto Group, Paratronix (LT-02P), and others. ASTM standards are and not freely available
This method is best for finding larger ("gross") leaks; small, microscopic leaks may not be detected, particularly if the product plugs the hole during vacuum testing. 2. The Principle Behind the Test
In the world of flexible packaging—ranging from food pouches to medical device bags—ensuring package integrity is critical. A small leak can lead to product spoilage, loss of sterility, or premature product failure. , titled "Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission," is the industry-standard procedure for identifying these leaks. For example, if a package fails at –70
This reapproval signifies that the methodology established in 2019 remains valid and reliable for current industry practices. If you have the 2019 version, you possess the same technical content as the 2021 file; the reapproval simply confirms the standard's ongoing relevance.
| | Value/Recommendation | |---|---| | Vacuum ramp rate | ~1 inch Hg per second | | Minimum dwell time | 30 seconds | | Common vacuum levels | 12, 18.5, or 24.5 inches Hg (approx. 40–83 kPa) depending on packaging type | | Working vacuum recommendation | ~70% of package failure pressure | | Test fluid | Water (typically) or other non-degrading fluid |
