Brick Compressive Strength Test Log (ASTM C67)

Inspection log for recording compressive strength test results on sampled fired brick per ASTM C67 and verifying compliance with the specified grade requirement and related ASTM brick specifications.

Inspection Identification

• Project, batch, and sample identification recorded
  Record the project name, lot or batch number, sample ID, and source of the brick sample.
• Inspection date and test location documented
  Enter the date and time the test was performed and the laboratory or site location.
• Specified brick grade or acceptance criterion identified
  Document the required minimum compressive strength or grade basis used for acceptance, including reference to the applicable specification.

Sample Preparation and Test Setup

• Sample count and specimen condition recorded
  Record the number of brick specimens tested and note whether specimens were intact, representative, and free of visible damage before testing.
• Specimen dimensions measured and documented
  Record measured dimensions used for area calculation, including length, width, and height as applicable.
• Testing machine identification and calibration status verified
  Document the compression testing machine ID, calibration date, and verification status before testing.
• Loading surfaces and capping or bedding method documented
  Record the specimen orientation, bearing surface condition, and any capping or bedding method used for the compressive strength test.

Compressive Strength Results

• Individual specimen compressive strength values recorded
  Enter each specimen's calculated compressive strength result and the corresponding failure load if available.
• Average compressive strength calculated
  Record the average compressive strength for the tested sample set.
• Lowest specimen result documented
  Record the lowest individual compressive strength result observed during the test set.
• Units of measure confirmed
  Select the unit used for reporting compressive strength results.

Compliance Review and Disposition

• Results meet specified grade requirement
  Confirm whether the measured compressive strength results meet or exceed the specified grade requirement.
• Non-conformance or deviation documented when applicable
  If results do not meet the requirement, document the deficiency, affected lot, and disposition or corrective action.
• Related observations recorded
  Record any additional test observations relevant to the brick sample condition or test outcome.

Sign-Off and Traceability

• Inspector name and signature completed
  Inspector or laboratory representative signs to confirm the accuracy and completeness of the recorded results.
• Reference report or supporting document attached
  Attach the test report, data sheet, or supporting evidence for traceability.
• Chain of custody or sample traceability noted
  Document the chain of custody, receiving record, or other traceability information for the tested brick specimens.
