USP 381
Elastomeric Closures Functionality Test USP 381 USP 381 defines functional testing requirements for elastomeric closures, focusing on penetrability, fragmentation, and self-sealing performance. These tests simulate real usage conditions to ensure closures maintain integrity, prevent contamination, and allow safe needle penetration. Compliance requires precise force measurement, controlled puncture procedures, and reliable leak detection. Proper instrumentation and […]
