Astm D3078 Pdf 2021 〈OFFICIAL · 2025〉

Because the pressure outside the package is lower than the pressure inside, the package inflates.

with minor editorial changes. Staying current with reapproved standards ensures: Compliance

No continuous bubbles are observed during the vacuum hold, and no fluid enters the package after pressure equalization.

ASTM D3078-21 now includes specific guidance on the ratio of the vacuum chamber volume to package volume. Improper sizing (too large a chamber) can dampen the vacuum ramp rate, missing small leaks.

The utilizes a visual detection method where a package is immersed in a liquid within a vacuum chamber.

Fill the vacuum chamber with the test liquid (water + 0.05–0.5% non-foaming surfactant). Because the pressure outside the package is lower

This test method is applicable to flexible packaging materials, including pouches, bags, and sachets. Common industries relying on this standard include: Sterile blister packs and pouches.

While the standard does not prescribe a single universal vacuum level, the 2021 edition provides better guidance on selecting vacuum levels based on package type and seal strength. It warns against applying excessive vacuum that could artificially rupture seals (non-leak related failure).

If a leak exists, internal air will escape, creating a continuous or localized stream of bubbles.

| | 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 | Common reasons for failures and how to fix them

The procedure is straightforward but requires specific ASTM D3078 Compliant Equipment to ensure repeatable results. 1. Equipment Setup

Other platforms like ANSI or IHS Markit provide access to these standards.

| Specification | Description | | :--- | :--- | | | ASTM D3078-02(2021)e1 | | Test Sensitivity | The standard is designed to detect "gross leaks" and its sensitivity is approximately 1 x 10⁻⁵ atm·cm³/s (or 1 x 10⁻⁶ Pa·m³/s ). | | Limitation | The method is explicitly not suitable for detecting small (micro) leaks due to the physics of the test. As the 2021 edition clearly states, "Small leaks may not be detected by this procedure". | | Safety & Environment | The 2021 edition reinforces the user's responsibility to follow appropriate safety, health, and environmental practices , aligning with modern standards for handling and disposal. | | International Alignment | It reaffirms that ASTM D3078 is developed in line with the World Trade Organization's (WTO) principles for the development of international standards. |
