    Seal Integrity Test – ASTM F1929 Method A (Dye Penetration Test)

    1. Purpose of the Test

    The ASTM F1929 standard describes a method to detect seal integrity failures in sterile medical packaging using a dye penetration technique.


    2. Method A – Dye Injection Technique

    In this method, dye solution is introduced into the inside of the package. If dye penetrates through the seal area to the outside, it indicates seal failure.

    Parameter Description
    Dye Used 0.5–1.0% Methylene Blue or Sudan Red
    Test Medium Inside of package (via syringe or tubing)
    Observation Time 5–20 seconds per seal area

    3. Test Procedure

    1. Prepare empty sterile barrier system

    2. Inject prepared dye solution inside the package (1–10 mL)

    3. Tilt or rotate to cover all seal edges

    4. Observe seals for any dye leakage

    5. Record results


    4. Acceptance Criteria

    Result Interpretation
    PASS No dye observed outside seal area
    FAIL Visible dye leakage through seal defects
