ISO/DIS 11357-8
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 11357-8 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee
SC 5, Physical-chemical properties.
ISO 11357 consists of the following parts, under the general title Plastics - Differential scanning calorimetry (DSC):
 Part 1: General principles
 Part 2: Determination of glass transition temperature
 Part 3: Determination of temperature and enthalpy of melting and crystallization
 Part 4: Determination of specific heat capacity
 Part 5: Determination of temperatures, times, heat of reaction and degree of conversion
 Part 6: Determination of oxidation induction time
 Part 7: Determination of crystallization kinetics
 Part 8: Determination of amount of water sorbed by polymers
Annex A is for information only.

DRAFT INTERNATIONAL STANDARD ISO/DIS 11357-8

Plastics — Differential scanning calorimetry (DSC) — Part 8:
Determination of amount of absorbed water
1 Scope
This International Standard specifies the testing method for determination of amount of adsorbed water in polymers
by differential scanning calorimetry in a dynamic mode.
