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.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

Introduction

The ISO 19935 series specifies temperature modulated differential scanning calorimetry (DSC) methods for the thermal analysis of polymers such as thermoplastics, thermosets and elastomers.

It is designed for observing and quantifying various phenomena or properties of the abovementioned materials such as

• physical transitions (glass transition, phase transitions like melting, crystallization, and cold crystallization, etc.);
• chemical reactions (cross-linking and curing of elastomers and thermosets, etc.);
• heat capacity;
• separation of overlapping thermal transitions.

This document describes the realization of several standardized thermoanalytical test methods which can be used for the determination of comparable data needed for data sheets or databases as well as for research purposes, but it can also be applied to quality assurance or to routine checks of raw materials and finished products, if desired. The procedures mentioned in this document apply as long as special product standards or standards describing special atmospheres for conditioning of samples do not require alternate provisions.

For scientific investigations or resolution of special analytical problems, all technical capabilities of the instruments beyond the provisions of this document may be used.

1 Scope

This document establishes general principles of temperature modulated differential scanning calorimetry (DSC) such as description of the principle and the apparatus, sampling, calibration and general aspects of the procedure and test report common to all parts of the ISO 19335 series.
