This procedure measures the amount of acetaldehyde in PET bottles 24 hours after blow molding.

This procedure measures the amount of acetaldehyde in PET resin or a PET preform.

This procedure evaluates the performance of a bottle when the container is pressurized to very high levels. Failure location reveals weak areas of the bottle.

This procedure utilizes Fourier transform infrared spectroscopy to measure the carbon dioxide concentration within carbonated beverage containers.

This procedure determines the CO2 shelf life of a given carbonated beverage container by evaluating the CO2 level within sample bottles over time using a CarboQC test instrument.

This procedure determines the CO2 shelf life of a given carbonated beverage container by evaluating the CO2 level within sample bottles over time using a Zahm & Nagel test device.

This procedure determines the coefficient of friction between two PET film samples using an adapted version of ASTM D1894-90.

This procedure determines a sample density and correlates that density to crystallinity using theoretical PET amorphous and crystalline densities according to ASTM D1505.

This procedure determines the amount of shrinkage in a blown container in the first 24 hours after blow molding by evaluating the bottle height and diameters and overfill volume at 0.5, 5 and 24 hours.

This procedure determines the wall thickness at given locations on samples using a magnetic thickness gauge.

This procedure determines the weight of specified container sections by physically cutting the container at defined locations.

The Finish Dimensions test is designed to ensure that all thread finishes on bottles or preforms comply with the dimensions and allowable tolerances specified on the respective bottle finish design drawings. In addition, there shall be no continuous or excessive flash, and no overhang between the F and G dimensions.

This procedure determines the amount of shrinkage in a blown container in the first 24 hours after blow molding by evaluating the bottle height and diameters and overfill volume at 0.5, 5 and 24 hours.

This procedure is designed to measure the dimensions of a bottle to insure the containers meet the requirements and tolerances specified on the bottle drawings.

This procedure measures the quantity of energy absorbed or released as the temperature of a plastic sample increases from 50°C to 300°C, is quench cooled and then reheated from 50°C to 300°C.

This procedure evaluates the performance of a heat set bottle when filled with heated water. The methodology used simulates filling and capping as found in production.

This procedure determines the weight, height and energy where a sample fails when it is impacted with a free-falling weight using the Bruceton Staircase Method.

This procedure determines the weight, height and energy at which a sample fails when it is impacted with a free-falling weight according to ASTM D3029-F.

This procedure is used to determine the intrinsic viscosity (IV) of the material. IV is a measure of the Molecular Weight (MW) of PET. The properties of PET are better at higher MW (higher IV) and worse at lower MW (lower IV). Comparing the SIV results from resin and molded parts can provide an understanding of the drying and process conditions.

This procedure measures the amount of moisture within a sample using the coulometeric Karl Fischer technique.

This procedure measures the permeation rate of oxygen through a container or film using a MOCON OX-Tran or Oxysense. The device will be selected based on the scope of the testing and the requirements of the container.

This procedure measures the permeation rate of CO2 through a bottle using a Control C IV Permatran test instrument.

This procedure tests the performance of bottles as they are pasteurized.

This procedure is used to measure properties like the elastic modulus, the stress and the strain properties of a material using either injection molded tensile bar specimens or thin sidewall specimens cut from container.

This procedure evaluates the performance of bottle bases when they are exposed to a 0.2% solution of NaOH (Sodium Hydroxide) to simulate the failure associated with Stress Cracking.

This procedure evaluates the performance of PET bottles when they are dipped in a stress agent and then subjected to high temperature and high humidity conditions.

The Thermal Stability Test is designed to insure that dimensional changes in carbonated PET bottles will not be excessive during their expected lifetime. This is also known as a “creep” test.

This procedure determines the angle at which a bottle will tip and fall once the center of gravity has been overcome on tilting.

To ensure that the vertical strength of PET bottles is sufficient to meet minimum performance standards for vertical loading as might be encountered during bottle filling, capping and stacking of filled product.

This procedure is used to determine the overfill (brimful) and fill line volume of each container in a set. This test can be used for either statistical information like average and standard deviation numbers or can be used to obtain mold specific information. Our typical test is either 12 samples chosen at random from a full mold round or it could be one container from each blow mold cavity.
