• Acetaldehyde

    AA Generation, Resin

    This procedure determines the AA generated by a resin as a function of time at a given temperature.

  • Carboxyl End Group Analysis for PET

    Carboxyl End Group Analysis for PET

    This procedure determines the carboxyl end group content in a PET sample.

  • Coefficient of Friction Testing

    Coefficient of Friction Testing

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

  • Color/Haze

    Preform/Bottle

    This procedure is used to determine the amount of haze and the degree of color exhibited by a preform or container sidewall. This is an indication of how effectively the material was processed and/or the material’s ability to be processed.

    Flake/Resin

    This procedure is used to determine the amount of haze and the degree of color exhibited by the resin or flake. This is an indication of how effectively the material was processed and/or the material’s ability to be processed.

  • Density

    Density

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

  • Impact

    Dart Impact – Bruceton Staircase Method

    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.

    Dart Impact – ASTM D3029-F

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

  • Melt Flow Curves

    Melt Flow Curves

    This test measures the melt flow curve of a PET sample at 3 temperatures and 8 shear rates.

  • Melt Index

    Melt Index

    This procedure determines the rate of extrusion of molten resin or ground samples through a die of specified length and diameter under prescribed temperature, load, and piston position as a function of time according to ASTM D1238.

  • Moisture Analysis

    PET

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

  • Sieve Analysis Particle Size

    Sieve Analysis Particle Size Distribution

    This procedure is used to determine the particle size distribution of plastic material as received from the source. It may be used on samples of incoming resin or flake used in recycling operations.

  • Percent Ash

    Percent Ash

    This procedure determines the percentage of ash in a submitted sample.

  • Stress Crack

    ISBT

    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.

    Caustic

    This procedure evaluates the performance of bottle bases when they are exposed to a 0.1% solution of NaOH (Sodium Hydroxide) to simulate the failure associated with Stress Cracking.

  • Tilt Test

    Tilt Test

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

  • UV/Visible/Near Absorption Spectra

    UV/Visible/Near IR Absorption Spectra

    This test determines the absorbance values in a material at varying wavelengths.
