Leak rate (%)
Equation: Pass rate (%) = (tested − leaked) ÷ tested × 100. Leak rate (%) = leaked ÷ tested × 100. The run passes when the leak rate is at or below the acceptance limit.
Method: Bubble emission leak testing per ASTM F2096 (detecting gross leaks in packaging by internal pressurization, bubble test). Packs are pressurised under water and watched for a steady stream of bubbles.
Assumptions: every pack in the run was tested the same way, at the same pressure and hold time; a leak is a steady bubble stream, not a single stray bubble.
Limitations: the bubble test finds gross leaks only — it cannot prove a pack is sterile or find pinholes below its detection limit; dye-penetration or vacuum-decay tests cover smaller defects.
Rounding: rates to 2 decimal places; counts are whole packs; intermediates unrounded.
This is a calculation aid, not a laboratory report — confirm against your accredited method before citing a value.

Worked example: 50 packs tested, 2 leaked: pass rate = 48 ÷ 50 × 100 = 96.00%; leak rate = 4.00%, which passes a 5% acceptance limit.
