Towel Absorbency Test Log - AATCC 79 / ASTM D4772

Inspection log for recording towel water-drop absorbency test conditions, absorbency time, and percent absorbency for terry towels against product specifications. Supports functional claims and quality verification for towel lines using AATCC 79 / ASTM D4772 terminology.

Inspection Identification

• Test record ID captured
  Unique log or batch record identifier for this absorbency test.
• Inspection date and time recorded
  Date and time the absorbency test was performed.
• Inspector name or ID recorded
  Name or employee ID of the person performing the test.
• Product style, SKU, or lot identified
  Towel style, SKU, item code, or lot number under test.
• Test standard referenced
  Standard used for the absorbency test.

Sample and Test Setup

• Sample condition acceptable before test
  Sample is clean, dry, and representative of the lot being evaluated.
• Number of towel specimens tested
  Count of individual towel specimens included in the test run.
• Specimen size or test area documented
  Measured specimen dimensions or defined test area used for the absorbency evaluation.
• Ambient test conditions recorded
  Room temperature and relative humidity at the time of testing.
• Water source and temperature recorded
  Water type/source and temperature used for the drop absorbency test.

Equipment and Calibration

• Dropper or dispensing device identified
  Device used to deliver the water drop for the absorbency test.
• Timing device available and functional
  Stopwatch, timer, or equivalent timing device is available and operating correctly.
• Equipment calibration or verification current
  Timing and dispensing equipment are within current calibration or verification status.
• Reference document or SOP available
  SOP, work instruction, or customer specification used to conduct the test.
• Test surface clean and non-absorbent
  Surface used for the test is clean and does not interfere with water-drop absorption timing.

Absorbency Test Results

• Water-drop absorbency time per specimen
  Time from drop placement until full absorption or defined endpoint, recorded for each specimen.
• Percent absorbency per specimen
  Percent absorbency result for each specimen or calculated average, per test method or internal specification.
• Average absorbency time meets specification
  Average absorbency time is within the approved product specification or claim limit.
• Average percent absorbency meets specification
  Average percent absorbency meets the approved product specification or claim limit.
• Replicate results are consistent
  Assess whether replicate specimens produced consistent absorbency performance.

Observations, Deficiencies, and Disposition

• Visible defects affecting absorbency noted
  Select any observable conditions that may affect absorbency performance.
• Non-conformance documented when results fail spec
  A deficiency or non-conformance is documented if any critical result is outside specification.
• Disposition selected
  Disposition for the tested lot or sample based on the absorbency results.
• Corrective action or follow-up recorded
  Document any corrective action, retest plan, or escalation required for failed absorbency results.
• Inspector signature
  Signature of the inspector or reviewer completing the log.
