Tempered Glass Fragmentation Test Log

Inspection log for recording tempered glass fragmentation test results, including fragment counts in a 50 x 50 mm area after breakage, to document conformance with ASTM C1048 and ANSI Z97.1 minimum particle requirements.

Inspection Header and Sample Identification

• Test date and time recorded
• Inspector name and role recorded
• Sample ID, lot number, and product description recorded
• Glass type confirmed as tempered sample
  Confirm the specimen is identified as tempered glass before fracture testing.
• Reference standard documented

Test Method and Break Procedure

• Break method documented and controlled
  Record the method used to fracture the sample and any controlled setup details.
• Breakage performed under safe, controlled conditions
  Verify the sample was broken in a controlled manner with appropriate PPE and handling.
• Fragment count recorded within 3 to 5 minutes after fracture
  Enter the elapsed time used for the count.
• Photo evidence of fracture pattern captured
  Upload a clear image of the fractured specimen and fragment field.

Fragment Count Measurement

• 50 x 50 mm area identified on sample
  Confirm the inspection area used for counting fragments is the specified 50 x 50 mm region.
• Fragment count within 50 x 50 mm area
• Fragments are small, granular, and uniformly distributed
  Verify the break pattern is consistent with tempered glass fragmentation.
• Edge condition and any large shards documented
  Record any abnormal shard size, edge behavior, or unusual fracture characteristics.
• Minimum particle requirement met
  Pass when the fragment count in the 50 x 50 mm area meets or exceeds the minimum requirement.

Compliance, Non-Conformance, and Sign-Off

• Test result disposition
• Non-conformance documented when applicable
  Describe any deficiency, out-of-spec fragment count, or test deviation.
• Corrective action or disposition recorded
  Record re-test, hold, reject, or other disposition if the sample fails.
• Inspector signature
• Reviewer or QA approval
