GB/T 42682-2023 Ships and marine technology - Testing specification for stairsteps using electrical resistance trace heating
1 Scope
This document specifies a test method to assess the performance of stairsteps 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.
IEC/IEEE 60079-30-1 Explosive atmospheres - Part 30-1: Electrical resistance trace heating - General and testing requirements
IEC/IEEE 60079-30-2 Explosive atmospheres - Part 30-2: Electrical resistance trace heating - Application guide for design, installation and maintenance
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
heated stairstep
stairstep that can be heated through a heating device on the stairstep 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
Stairsteps 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 (including fixings, connections, supports and foundations) shall ensure sufficient rigidity and stability;
b) all parts shall be resistant to environmental effects (such as due to climate, chemical agents, corrosive gases) e.g. by the use of a corrosion resistant material or with the aid of a suitable protective coating;
c) heated stairsteps that contain heat tracing and are installed in hazardous areas shall comply to IEC/IEEE 60079-30-1 and IEC/IEEE 60079-30-2.
Note: Material selection can be covered in statutory requirements of the national/local authorities and/or IACS requirements for the intended applications.
