Calorimetric analysis (DSC) on plastic material

Presentation for participants

Reference of the ILC: DSC-X-PL
References of test methods: ISO 11357-1  ASTM D3418
References of test methods for which the ILC can indirectly provide an assessment of performance ISO 11357-2  ASTM D3418  ASTM E1356  ISO 11357-3  ASTM D3418
ASTM E793  ISO 11357-4  ASTM E1269  ISO 11357-6  ASTM D3895
ISO 11357-7  ASTM E2041  ISO 11357-8
These may be superseded standards, which some of the reference standards may have replaced, or EN or ASTM or ISO standards that are close but not exactly equivalent to the reference standards.
Frequency: For this ILC, there is a risk that the number of registrations is low. To ensure an enough number participants, a pre-registration procedure is put in place, as follows:
1 - Participants interested in participating pre-register using the registration form. No invoicing is made for this pre-registration;
2 - When at least 10 potential participants have pre-registered, CompaLab asks each of these pre-registrees to confirm their willingness to participate and what are the characteristics for which they commit to provide results;
3 - If at least 8 participants confirm their intention to participate, the CIL organisation concerned is engaged.
Main characteristics: Glass transition temperature and step height (ISO 11357-2 ASTM D3418 ASTM E1356), Temperature and melting-crystallisation enthalpy (ISO 11357-3 ASTM D3418 ASTM E793), Specific heat capacity (ISO 11357-4 ASTM 
E1269), Temperature, Characteristic reaction time and enthalpy (ISO 11357-5 ASTM E2070), Oxidation induction time (isothermal OIT) and temperature (dynamic OIT) (ISO 11357-6 ASTM D3895), Melting-crystallisation kinetics (ISO 11357-7 ASTM E2041), Thermal conductivity (ISO 11357-8)
Determination of the assigned values (“true values” for each characteristic): By statistical computation of the totality of the results with possible selection on competence criteria (accreditation, validation by a reference body, quantity of tests performed in the year), test to detect possible collusion, merging of results not obtained in reproductibility conditions, suppression of technically unvalid results.
Type of statistical computation: For numerical results, the statistical computation will provide an assigned value with its attached uncertainty, values of standard deviations for repeatability and reproductibility, limits of alerts for bias and repeatability of the participant, indiviual values for uncertainty of results of participants.
