Dieses Dokument legt ein Verfahren zur Beurteilung der Nachbrennzeit einer Flamme fest, die auf die Kante eines Dochts aus nicht entflammbarem Werkstoff, der in eine schwer entflammbare Flüssigkeit getaucht ist, einwirkt.
Diese Prüfung bestimmt nicht das Verhalten einer versprühten schwer entflammbaren Flüssigkeit.
ANMERKUNG   Derartige Prüfungen sind in ISO 15029 1 und ISO 15029 2 festgelegt.
Dieses Dokument legt eine von vier grundlegenden Prüfungen zur Bestimmung der Entflammbarkeit fest.
Dieses Dokument gilt nicht für bestimmte Flüssigkeiten wie solche der Kategorien HFAE und HFAS.

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).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 28, Petroleum and related products, fuels

and lubricants from natural or synthetic sources, in collaboration with the European Committee for

Standardization (CEN) Technical Committee CEN/TC 19, Gaseous and liquid fuels, lubricants and related

products of petroleum, synthetic and biological origin, in accordance with the Agreement on technical

cooperation between ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 14935:1998), which has been technically

revised. The main changes compared to the previous edition are as follows:
— material data of the reservoir have been changed;
— some designations have been changed;
— drawings have been revised;

— tolerances in ignition and dropping times and nozzle dimensions have been tightened for better

accuracy.

Any feedback or questions on this document should be directed to the user’s national standards body. A
