Eagle Labs Aw water-activity fail board is not moisture LOD fail
Open one Eagle Labs Aw water-activity fail board. Count lots / samples that failed the Aw (water activity) acceptance limit. Divide by Aw tests the written program required. That ratio is EL water-activity-fail % — LOD moisture rejects and cleaning-validation fails stay off this board.
Pair: Water-activity fail share on Stock. Moisture twin: EL moisture-fail. Cleaning twin: EL cleaning-fail.
Aw water-activity board math
Aw fails — Eagle Labs water-activity tests that failed Aw acceptance on the Aw fail board.
Aw tests — Eagle Labs water-activity tests the written program required for that lot / suite.
EL water-activity-fail % = Aw fails ÷ Aw tests × 100. Fat EL water-activity-fail % usually means dryer dwell, binder moisture, or room humidity on that suite — chase that station; never invent an EL water-activity-fail chip.
Hard stops
Do not invent EL water-activity-fail %. Do not dump NutraScience or Vitaquest Aw files into Eagle boxes. Do not fold LOD moisture rejects, cleaning fails, or microbial fails into Aw-fail counts. Do not blend suites when one line owns the fail pile.

Procedure
- Type Aw fails and Aw tests.
- Read EL water-activity-fail %.
- Chase dryer / humidity discipline when EL water-activity-fail % is material.
Failure modes
- Inventing EL water-activity-fail %.
- Dumping a NutraScience or Vitaquest Aw file into Eagle fields.
- Folding LOD moisture rejects, cleaning fails, or microbial fails into Aw-fail counts.

FAQ
- Is this Eagle Labs moisture-fail rate?
- Water activity (Aw) vs LOD / moisture. [Moisture-fail rate](/manuals/eagle-labs-moisture-fail-rate) counts LOD rejects. Here you count Aw water-activity fails over Aw tests on the Aw fail board.
- Is this Eagle Labs cleaning-validation fail share?
- Aw acceptance fails vs cleaning swab / rinse fails. [Cleaning-validation fail share](/manuals/eagle-labs-cleaning-validation-fail-share) stays on cleaning logs. Fail / test Aw rows belong on this water-activity board.
- What EL water-activity-fail % should I invent?
- None. Source Aw fails and Aw tests from the same Eagle Labs Aw water-activity fail board.
