Astm D3078 Pdf 2021 🎯 Bonus Inside

ASTM D3078-02(2021) outlines a vacuum-based bubble emission test to identify gross leaks in flexible packaging, specifically targeting seals in pouches and blister packs. The procedure requires submerging packages in a vacuum chamber, with limitations noted for small leaks and reliance on operator interpretation. For more details, visit AMETEK MOCON

• Flexible pouches (stand-up pouches, flat pouches)
• Sealed trays with lidding film
• Bags and sachets
• Medical device packaging (e.g., sterile barrier systems)

1. Preparation of Test Specimens: Sealant samples are prepared according to the manufacturer's instructions and applied to a substrate.
2. Curing: The sealant samples are cured under specified conditions, including temperature, humidity, and time.
3. Examination: The cured sealant samples are examined visually or using a magnifying device to detect the presence of bubbles.
