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. www .iso .org/directives

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

handrails using electrical resistance trace heating
1 Scope
This document specifies a test method to assess the performance of handrails using electrical resistance
trace heating to provide anti-icing in low temperature environments, when installed for exterior
applications. It includes requirements for the test facility, the test conditions, the test specimens, the
test procedures and the test report.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

maintenance
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https: //www .iso .org/obp
— IEC Electropedia: available at http: //www .electropedia .org/
3.1
heated handrail
handrail that can be heated through a heating device on the handrail to prevent falling accidents
3.2
anti-icing
prevention of ice formation on protected surfaces
3.3
ambient temperature
temperature of the air in the test chamber
4 Construction and materials
Handrails should be designed and constructed using materials that withstand the foreseeable
conditions of use. In particular, at least the following details shall be considered:
a) dimensioning and selection of components shall ensure sufficient rigidity and stability;
b) all parts shall be resistant to environmental effects (such as due to climate, chemic
