This is a complete technical guide to ASTM D3078-21: Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission.

• The "19": Indicates the original technical revision was made in 2019.
• The "(2021)": Indicates the standard was reapproved by the ASTM committee in 2021 without any technical changes to the method itself.

ASTM D3078-02(2021)e1 defines a bubble emission method for detecting gross leaks in flexible and semi-rigid packaging, typically identifying leaks down to 1 x 10⁻⁵ atm cm³/s. The 2021 reapproved standard involves submerging packages in a vacuum chamber, with results used to ensure seal integrity in food, pharmaceutical, and medical applications.

• Legal Compliance: For ISO 17025 accreditation (testing labs), you must have the current, official version. Photocopies or screenshots are not audit-compliant.
• Intact Figures and Tables: Unofficial PDFs often have missing vacuum diagrams, chamber schematics, or watermanometer calibrations.
• Revision Alerts: When you buy from ASTM, you get 1 year of revision tracking (Redline version) showing changes from D3078-18 to D3078-21.

Q3: What is the difference between ASTM D3078 and ASTM F2338?

• D3078: Bubble emission (subjective, qualitative, but low cost).
• F2338: Vacuum decay (instrumental, quantitative, but requires expensive sensors).
