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.
