1. Standard Tolerance Range:

• According to ASTM B265 standard, the tolerance range for the thickness of GR2 titanium plates should be within ±5%. This means that for a 7mm GR2 titanium plate, the allowable thickness range is from 6.65mm to 7.35mm.

2. How to Inspect:

• Thickness Measurement: Use precision thickness gauges or micrometers to measure the thickness at various positions of the titanium plate and compare it with the standard value.

• Chemical Composition Inspection: Employ chemical analysis methods as per ASTM B265 to inspect whether the chemical composition of the titanium plate meets the standard requirements.

• Mechanical Performance Inspection: This includes tensile tests, bending tests, etc., to ensure that the mechanical properties of the titanium plate meet the standard requirements.

3. Considerations During Inspection:

• Ensure Accuracy of Measurement Instruments: Use high-precision measuring instruments and calibrate them regularly to ensure accuracy.

• Sample Selection: Randomly select samples from the titanium plate for inspection to ensure the representativeness of the results.

• Follow Standard Testing Procedures: Strictly follow the testing procedures specified in ASTM B265 to ensure the reproducibility and comparability of the tests.

• Record and Report: Record the results of each inspection and generate detailed inspection reports as required, including measured values, standard requirements, and result evaluations.

• Safety Operations: Follow safety procedures when conducting any tests or operations, especially when handling metals like titanium, to prevent hazards such as sparks, flames, and dust.

• Environmental Conditions: Inspections should be conducted under appropriate environmental conditions to avoid factors that may affect measurement results, such as temperature, humidity, etc.

In summary, inspecting GR2 titanium plates using ASTM B265 standards requires strict adherence to the standard requirements, using appropriate instruments and methods for testing, and paying attention to safety and environmental conditions.
