Plastics - Differential scanning calorimetry (DSC) - Part 1: General principles (ISO 11357-1:2016)
ISO 11357-1:2016 specifies several differential scanning calorimetry (DSC) methods for the thermal analysis of polymers and polymer blends, such as
- thermoplastics (polymers, moulding compounds and other moulding materials, with or without fillers, fibres or reinforcements),
- thermosets (uncured or cured materials, with or without fillers, fibres or reinforcements), and
- elastomers (with or without fillers, fibres or reinforcements).
ISO 11357-1:2016 is intended for the observation and measurement of various properties of, and phenomena associated with, the above-mentioned materials, such as
- physical transitions (glass transition, phase transitions such as melting and crystallization, polymorphic transitions, etc.),
- chemical reactions (polymerization, crosslinking and curing of elastomers and thermosets, etc.),
- the stability to oxidation, and
- the heat capacity.
ISO 11357-1:2016 specifies a number of general aspects of differential scanning calorimetry, such as the principle and the apparatus, sampling, calibration and general aspects of the procedure and test report common to all following parts.
Details on performing specific methods are given in subsequent parts of ISO 11357 (see Foreword).

Polimerni materiali - Diferenčna dinamična kalorimetrija (DSC) - 1. del: Splošna načela (ISO 11357-1:2016)
Standard ISO 11357 določa različne metode diferenčne dinamične kalorimetrije (DSC) za toplotno analizo polimerov in mešanic polimerov, kot so:
– plastomeri (polimeri, zmesi za oblikovanje in drug material za oblikovanje, s polnili, vlakni in ojačitvami ali brez njih),
– termoreaktivni materiali (nestrjeni ali strjeni materiali s polnili, vlakni in ojačitvami ali brez njih) in – elastomeri (s polnili, vlakni in ojačitvami ali brez njih).
Standard ISO 11357 je namenjen za opazovanje in merjenje različnih lastnosti (in z njimi povezanih pojavov) zgoraj omenjenih materialov, kot so:
– fizične prehodnosti (prehodnost stekla, prehodna stanja, kot sta topljenje in kristalizacija,
polimorfna prehodnost, itd.),
– kemične reakcije (polimerizacija, prečno povezovanje in strjevanje elastomerov in termoreaktivnih materialov itd.),
– odpornost proti oksidaciji in
– toplotna kapaciteta.
Ta del standarda ISO 11357 določa število splošnih lastnosti diferenčne dinamične kalorimetrije, kot so načelo in aparat, vzorčenje, kalibracija splošnih lastnosti postopka in poročila o preskušanju, skupna vsem naslednjim delom.
