IEC 60332‑1‑2:2025 specifies the procedure for testing the resistance to vertical flame propagation for a single vertical electrical insulated conductor or cable, or optical fibre cable, under fire conditions using a 1 kW pre-mixed flame. The apparatus is described in IEC 60332‑1‑1.
NOTE 1 Testing to IEC 60332‑1‑2 can be performed simultaneously with that to IEC 60332‑1‑3, if required.
This group safety publication focusing on test method(s) is primarily intended to be used as a product safety standard for the products mentioned in the scope, but is also intended to be used by technical committees in the preparation of standards for products similar to those mentioned in the scope of this group safety publication, in accordance with the principles laid down in IEC Guide 104 and lSO/lEC Guide 51.
NOTE 2 The performing of this test method on a single insulated conductor or cable or optical fibre cable does not provide compliance with fire propagation requirements in relevant standards in the case that the single insulated conductor or cable or optical fibre cable is installed with or amongst other cables as a group. (See the IEC 60332‑3 series).
One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications and/or group safety publications in the preparation of its publications.

IEC 60331-4:2024 specifies the test apparatus and procedure, and gives the performance requirements, including recommended flame application times and flame temperatures, for power cables of rated voltage higher than 0,6/1,0 kV up to and including 18/30 kV for maintaining circuit integrity when subject to fire and mechanical shock under specified conditions.
The test method in this document is restricted to conductor sizes up to and including 120 mm2. The test results for 120 mm2 size conductors constructions qualify larger cross-sections of the same cable construction.
In the case of preassembled three-core cables, then the complete cable is considered as tested when a complete single-core of the cable has been tested.
This document includes details for the specific point of failure, continuity checking arrangement, test sample, test procedure and test report relevant to electric power cables with a rated voltage higher than 0,6/1,0 kV up to and including 18/30 kV.
Annex A provides the method of verification of the burner and control system used for the test.
Annex B provides a choice of the recommended test apparatus.
Annex C provides, as an option, guidance for using either water spray or water jet protocols.
Annex D provides, as an option, the flame temperature of 1 000 °C, which is applicable for special applications.
Requirements are stated for an identification that can optionally be marked on the cable to signify compliance with this document.
This group safety publication focusing on the test method for circuit integrity safety for power cables of rated voltage higher than 1 kV up to and including 30 kV under fire conditions, is primarily intended to be used as a product safety standard for the products mentioned in the scope, but is also intended to be used by TCs in the preparation of publications for products similar to those mentioned in the scope of this group safety publication, in accordance with the principles laid down in IEC Guide 104 and lSO/lEC Guide 51.
One of the responsibilities of a TC is, wherever applicable, to make use of either BSPs or GSPs, or both, in the preparation of its publications.
WARNING – The test given in this document can involve the use of dangerous voltages and temperatures. Suitable precautions should be taken against the risk of shock, burning, fire and explosion that can arise, and against any noxious fumes that can be produced.

IEC 60287-2-3:2024 describes a method for calculating the continuous current rating factor for cables of all voltages installed in ventilated tunnels. The method is applicable to any type of cable. The method applies to natural as well as forced ventilation. Longitudinal heat transfer within the cables and the surroundings of the tunnel is assumed to be negligible. All cables are assumed to be identical within the tunnel and it is assumed that the tunnel cross-section does not change with distance along the tunnel.

IEC 60502-2:2014 specifies the construction, dimensions and test requirements of power cables with extruded solid insulation from 6 kV up to 30 kV for fixed installations such as distribution networks or industrial installations. When determining applications, it is recommended that the possible risk of radial water ingress is considered. Cable designs with barriers claimed to prevent longitudinal water penetration and an associated test are included in this part of IEC 60502. Cables for special installation and service conditions are not included, for example cables for overhead networks, the mining industry, nuclear power plants (in and around the containment area) nor for submarine use or shipboard application. This third edition cancels and replaces the second edition, published in 2005, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) a simplified calculation procedure for the thickness of the lead sheath and the oversheath;
b) a new subclause for the determination of the cable conductor temperature;
c) a modified procedure for the routine voltage test;
d) a new subclause for a routine electrical test on oversheath;
e) modified requirements for the non-metal sheaths including semi-conductive layer;
f) modified tolerances for the bending test cylinder;
g) the inclusion of a 0,1 Hz test after installation.
In addition, the modified structure of the IEC 60811 series has been adopted for this third edition.
