OverviewWhat Is ASTM C147 Glass Container Internal Pressure Strength?
ASTM C147 specifies a standardized method for determining the internal pressure strength of glass containers such as bottles and jars. The test evaluates the ability of containers to withstand internal pressure without failure, ensuring structural integrity during filling, storage, and transportation. It is critical for assessing the safety of containers used with pressurized or carbonated contents.
This method is widely used to verify container performance under simulated service conditions. By measuring burst pressure and failure characteristics, ASTM C147 helps manufacturers optimize design, improve quality control, and ensure compliance with safety requirements for glass packaging applications.

ASTM C147 Glass Container Internal Pressure Strength FAQs
ASTM C147 is used to determine the internal pressure strength of glass containers by measuring the pressure at which they fail. It helps ensure container safety and performance when used with pressurized or carbonated products.
This test is important because glass containers may fail under pressure during use. Evaluating their strength helps prevent accidents, ensures product safety, and improves packaging reliability.
Hydraulic testing uses water and is safer, while pneumatic testing uses air and may pose higher risk due to sudden energy release during failure.
Common failure modes include cracking, fragmentation, or explosive breakage. These patterns help identify weak points in the container design.
ASTM C147 helps manufacturers detect defects, maintain consistent quality, and ensure that glass containers meet required safety and performance standards.
Lightweight glass bottles can be evaluated for internal pressure resistance using ASTM C147. Bottles are subjected to controlled internal pressure to assess their breaking strength and ability to withstand pressure during use. Additional impact and packaging tests may be needed to evaluate transport safety.
ASTM C147 measures the internal pressure strength of glass containers by applying either a constant pressure for a specified period or increasing pressure at a controlled rate until failure. The pressure at failure or the ability to withstand a specified pressure is recorded to assess container strength and suitability for pressurized products.
