Thermal Stress Testing: The ASTM C149 Standard

What is ASTM C149?

This is the standard test method for thermal shock resistance of glass containers. It involves rapid immersion in water baths of varying temperatures.

Compliance for Exporters

B2B suppliers exporting to the US must often provide ASTM C149 test results to satisfy the safety requirements of major retail chains.

Product Safety Assurance

Ensuring compliance reduces the risk of in-store breakage and subsequent product recalls or liability claims.
