Brick Freeze-Thaw Durability Test Log (ASTM C67)

Inspection log for recording freeze-thaw cycling results on sampled brick in accordance with ASTM C67 to support qualification of Grade SW severe weathering brick and document durability evidence.

Inspection Identification and Traceability

• Project, batch, and test lot identification recorded
  Record the project name, brick batch or lot number, and test lot identifier.
• Sample source and manufacturer documented
  Identify the manufacturer, plant, product line, and sampling location or source.
• ASTM C67 freeze-thaw test reference confirmed
  Confirm the test is being performed and recorded under ASTM C67 procedures.
• Target classification for Grade SW severe weathering documented
  Confirm the test objective is to support Grade SW severe weathering qualification or equivalent durability evidence.

Specimen Condition and Preparation

• Number of specimens tested
  Enter the total number of brick specimens included in the test set.
• Specimens visually inspected before cycling
  Confirm each specimen was inspected for pre-existing cracks, chips, spalls, or other defects before testing.
• Specimen dimensions recorded
  Record measured dimensions or reference dimensions for the specimens used in the test.
• Pre-test specimen condition documented with photos
  Attach photographs showing specimen condition before freeze-thaw cycling.
• Conditioning method and saturation state documented
  Describe the conditioning method used before cycling, including moisture state or saturation procedure.

Freeze-Thaw Cycling Parameters

• Test chamber temperature range within specified limits
  Record the chamber temperature range observed during cycling.
• Freeze-thaw cycle count completed
  Enter the number of cycles completed for the test set.
• Cycle duration and dwell times recorded
  Document freeze and thaw dwell times, ramp times, and any hold periods used in the test sequence.
• Water exposure or immersion conditions documented
  Record whether specimens were immersed, sprayed, or otherwise exposed to water during cycling and describe the method.
• Calibration status of chamber and measurement devices verified
  Confirm temperature sensors, timers, and any balance or measurement devices were within calibration at time of test.

Post-Test Results and Defects

• Visible cracking, spalling, or disintegration observed
  Indicate whether any visible cracking, spalling, scaling, or disintegration was observed after cycling.
• Mass change recorded
  Record the mass change for the specimen set before and after testing.
• Individual specimen damage summary documented
  Summarize the condition of each specimen or identify any outliers, failures, or notable damage patterns.
• Post-test photographs captured
  Attach photographs showing the final condition of the specimens after freeze-thaw cycling.
• Test anomalies or interruptions recorded
  Document any chamber malfunction, power interruption, specimen handling issue, or other anomaly affecting results.

Compliance Review, Disposition, and Sign-Off

• Results meet project acceptance criteria for severe weathering brick
  Confirm whether the observed results meet the specified acceptance criteria for Grade SW or project-defined durability requirements.
• Non-conformance or corrective action documented if failed
  If the test did not meet criteria, document the non-conformance, disposition, and any corrective action required.
• Reference report number or laboratory record entered
  Enter the linked report number, lab record ID, or chain-of-custody reference for traceability.
• Inspector or laboratory sign-off completed
  Capture the signature of the responsible inspector, technician, or laboratory representative.
