Introduction to TEC-7 and TEC-9 Glass Bottle Quality Assessments

Quality assessment suite of testing for glass bottles, jars and container glass (packaging) to determine all aspects of quality, performance and fitness-for-purpose of bottles for carbonated (TEC 7) and non-carbonated (TEC 9) glass packaging - to container-specific industry standards. These suites include key performance criteria such as vertical load, annealing, impact, glass thickness and weight, dimensions, ovality, verticality, push-up measurement, slip-angle, hot-end and finish coatings, capacity and headspace/vacuity.

Please Note: The quality assessment suites below incorporate a number of both UKAS ISO 17025:2005 accredited and non-accredited test methods. These are clearly indicated on all test reports, but please contact us for further details.


TEC 7 - Strength and Performance Standards for the Use of Carbonated Beverage Bottles

This suite of testing requires a minimum of 82 bottles for comprehensive verification of carbonated glass bottles to the standards laid down in the industry standard, ' TEC-7 Strength and Performance Standards for the Use of Carbonated Beverage Bottles.' The tests included in this suite include:

Dimensional Aspects:

  • Diameter, heel and shoulder;
  • Ovality mid body;
  • Height;
  • Verticality;
  • Thickness, including two profiles to show glass distribution. Areas measured for thickness include shoulder, body, heel, bearing surface, centre base;
  • Capacity.

Physical Aspects and Mechanical Strength:

  • Annealing;
  • Internal pressure including location of origin;
  • Vertical load including location of origin;
  • Thermal Shock;
  • Impact heel;
  • Impact shoulder;
  • Hot end coating heel and shoulder;
  • Finish coating;
  • Slip angle - or - industry standard rub-test.

TEC 9 - General Guidelines for the Use of Glass Containers

This suite of testing requires a minimum of 62 bottles for comprehensive verification of glass bottles to the standards laid down in the industry standard, ' TEC 9 - General Guidelines for the Use of Glass Containers'.

The TEC 9 suite includes the same dimensional and physical assessments as TEC 7 with the exception of internal pressure resistance.
