Overview
EN 60332-1-2:2004/A12:2020 is a CLC/CENELEC amendment to the EN 60332-1-2 series describing a standardized fire test for vertical flame propagation on a single insulated electrical conductor, cable, or optical fibre cable. The procedure uses a 1 kW pre‑mixed (gas/air) flame to assess a specimen’s tendency to ignite and sustain vertical flame propagation under controlled laboratory conditions. Amendment A12 (approved 2020-11-05) updates mounting and positioning requirements to ensure valid and repeatable results.
Key Topics and Requirements
- Scope: Procedure for testing resistance to vertical flame propagation of a single vertical insulated wire, cable, or optical fibre cable using a 1 kW pre‑mixed flame.
- Test flame application: Use of a pre‑mixed gas/air flame with a defined impingement point (the “blue cone”) on the test piece.
- Positioning of test piece: The test is valid only if the specimen remains in the test flame for the whole test. Amendment A12 adds provisions when the specimen moves out of the flame (for example due to breaking at the flame impact point).
- Optional securing loops (A12):
- Use 1 mm diameter metal wire loops applied around the test piece if it moves out of the flame.
- Place loops approximately 50 mm below and 50 mm and 150 mm above the blue cone impingement position.
- Attach loops to the metallic enclosure side walls or to a vertical rod/rail at the back; at test start, loops must not touch the specimen.
- Inner diameter of loops must exceed the cable diameter by at least 4.0 mm.
- Documentation and figures: Figure 2 (application of flame to test piece) is replaced to reflect the optional securing loops and updated geometry.
Applications and Users
This standard is widely used by:
- Cable manufacturers for product development and flammability verification
- Independent testing laboratories undertaking cable fire performance testing
- Specifiers, procurement teams, and compliance officers in construction, transportation, telecommunications and utilities requiring verified cable fire behavior data
- Regulatory bodies and certification organizations assessing compliance with national or sectoral fire-safety requirements
Practical benefits include consistent, repeatable assessment of a single conductor or cable’s vertical flame propagation behavior, helping manufacturers reduce fire risks and enabling purchasers to compare fire performance.
