Overview
IEC 60332-1-2:2004/AMD1:2015 is an important amendment to the international standard concerning fire safety tests on electric and optical fibre cables. This amendment focuses specifically on testing the vertical flame propagation behavior of a single insulated wire or cable using a 1 kW pre-mixed flame. Developed by the International Electrotechnical Commission (IEC) Technical Committee 20 on Electric Cables, this update refines the testing procedures to ensure consistent and reliable fire performance assessment under controlled fire conditions.
Fire safety in cables is critical as it directly affects the overall safety of electrical installations, especially in environments where flame spread must be minimized to prevent larger fire hazards. This amendment advances the methodology by clarifying sample preparation, flame application, positioning of test specimens, and precise measurement techniques.
Key Topics
Test Scope and Procedure
The amendment defines a standardized method to test vertical flame propagation on a single insulated wire or cable section. It specifies the use of a 1 kW pre-mixed blue flame applied for a determined time based on cable diameter to replicate fire exposure realistically.Sample Preparation and Measurement
Samples must be insulated conductors or cables, each measuring approximately 600 ± 25 mm in length. The diameter measurement techniques have been updated to align with IEC 60811-203, ensuring accurate and repeatable determination of cable dimensions critical for test timing.Sample Positioning in Test Apparatus
The test cable is mounted vertically and centered in a metal enclosure set 50 mm from the base, secured with copper wires. Precise spatial arrangements for the test specimen position and the burner flame impact point are mandated to maintain consistency between tests.Flame Application and Duration
Burning parameters require the burner to be angled at 45° ± 2° to the vertical axis with the flame tip impinging exactly 475 ± 5 mm from the upper support's bottom edge. The flame application duration correlates to the measured overall diameter, with specific rules for round and non-circular cables to address various cable geometries rigorously.Updates to Normative References and Terminology
The amendment incorporates new normative references including IEC 60811-203 for dimensional measurement and aligns terminology for fire safety with ISO 13943 definitions, supporting clarity and harmonization with other international fire safety standards.
Applications
Cable Manufacturing and Quality Assurance
Manufacturers utilize IEC 60332-1-2:2004/AMD1:2015 to verify their insulated wires and cables meet fire safety criteria, ensuring products resist vertical flame spread and reduce fire propagation risks in installed conditions.Building and Electrical Safety Compliance
Regulatory bodies and safety inspectors may reference this test method to confirm that electrical installations conform to fire safety standards, fostering safer building environments, especially in high-risk areas like public buildings, transportation systems, and industrial facilities.Product Development and Certification
The amendment guides test labs and certifiers in performing consistent, standardized flame propagation tests, facilitating product certifications required for international trade and market access.Fire Risk Assessment and Engineering
Fire safety engineers incorporate test results based on this standard in assessing overall building fire risk and designing fire-retardant cable systems to comply with stringent safety regulations.

3 Terms and definitions
Replace the existing source of item 3.1 by the following new source:
[SOURCE: ISO 13943:2008, 1.489]
Replace the existing source of item 3.2 by the following new source:

5.1 Sample
Replace the existing subclause by the following new subclause:
The test sample shall be a piece of single insulated conductor or cable (600 ± 25) mm long.
The test sample diameter shall be measured using the method given in IEC 60811-203. The
measurement shall be made at each of three places, separated by at least 100 mm.
© IEC 2015
The average of the three values obtained shall be rounded to obtain the overall diameter. If
the calculation gives 5 or more for the second decimal figure, raise the first to the next
number; thus, for example, 5,75 is rounded to 5,8. If the calculation gives 4 or less for the
second decimal figure, maintain the first number; thus, for example, 5,74 is rounded to 5,7.
The overall diameter obtained shall be used for the selection of the time for flame application.
5.3 Positioning of test piece
Replace the existing subclause by the following new subclause:
The test piece shall be straightened and secured to two horizontal supports by means of a
suitable size of copper wire, in a vertical position in the centre of the metal enclosure, as
described in IEC 60332-1-1, so that the distance between the bottom of the upper support and
the top of the lower support is (550 ± 5) mm. In addition, the test piece shall be positioned so
that the bottom of the specimen is approximately 50 mm from the base of the enclosure (see
Figure 1).
