According to ASTM B265 standard, the tolerance size and points to note in the inspection of GR2 titanium plates are as follows:

1. Tolerance Size:

   • The tolerance range specified by ASTM B265 for GR2 titanium plates is typically ±10% of the thickness, meaning for a 2mm thickness titanium plate, the tolerance range would be ±0.2mm.

2. Points to Note in Inspection:

   • Visual Inspection: Before any measurements, conduct a visual inspection of the titanium plate. Check for any visible defects, surface imperfections, or damage.
   • Dimensional Measurement: Use appropriate tools (such as micrometers or other high-precision measuring instruments) to measure the thickness of the titanium plate. Ensure multiple measurements are taken at different locations to ensure consistency.
   • Flatness Check: Inspect the flatness of the titanium plate to ensure it meets specification requirements. This can be done using a straight edge or flatness measuring instrument on the surface.
   • Chemical Composition Analysis: Depending on ASTM B265 requirements, chemical composition analysis may be required to verify if the titanium plate meets specified composition requirements.
   • Mechanical Performance Testing: Depending on requirements, tensile testing, hardness testing, or other mechanical performance tests may be necessary to ensure the titanium plate meets specified strength and hardness requirements.
   • Specific Requirements: Ensure compliance with any specific customer requirements or project specifications during the inspection process. This may involve additional tests, checks, or documentation.
   • Recordkeeping: Maintain records of all measurement data, test results, and any identified defects or issues during inspection. These records are crucial for ensuring product compliance with quality standards and tracking throughout the manufacturing process.

These are the key considerations for inspecting GR2 titanium plates according to ASTM B265 standard. Ensure thorough reading and adherence to applicable standards and specifications before conducting any inspection to ensure accuracy and reliability of the inspection process.
