Overview
EN 61034-2:2005/A2:2020 is a European standard developed by CLC that addresses the measurement of smoke density from cables burning under defined conditions. This document is an amendment to EN 61034-2:2005 and specifies the test procedures and requirements to assess the smoke density produced by burning cables. It plays a critical role in evaluating fire safety and material behavior of electrical cables, particularly in environments where smoke production and visibility impairment pose significant safety risks.
The standard is closely aligned with the International Electrotechnical Commission publication IEC 61034-2:2005/A2:2019 and sets the criteria for conducting repeatable and standardized tests. It is intended for use by manufacturers, testing laboratories, and regulatory bodies involved in electrical cable quality and safety compliance.
Key Topics
Scope and Definitions
Defines the objective and the controlled conditions under which cables are burned to measure smoke density. It focuses specifically on cables' ignitability and burning behavior.Test Procedure
Details the method for mounting cable test samples, including the binding and tensioning of cable bundles to avoid movement during testing. The procedure ensures reproducibility and accuracy.Measurement Technique
Describes the measurement of light transmittance through smoke generated during cable combustion as an indirect indicator of smoke density. This includes normalization methods for cables of different diameters.Smoke Density Evaluation
Provides a formula to normalize the light transmittance results based on cable diameter and number of test pieces, allowing consistent result comparisons between cables.Requirements and Compliance
Specifies minimum transmittance values (expressed as percentages) for compliance based on relevant cable specifications. If unspecified, recommendations from Annex B of the standard may be followed.Amendment Highlights
Updates include:- Modification to mounting of test samples
- Clarifications in smoke density evaluation methodology
- Removal of outdated references
- Alignment with current best practices in cable testing
Applications
Cable Manufacturing Quality Assurance
Enables manufacturers to test and certify cables for fire safety by measuring smoke density generated during combustion, ensuring compliance with safety standards.Fire Safety Engineering
Assists fire safety engineers in selecting cables with lower smoke emission characteristics to improve visibility and reduce toxicity during fires.Regulatory Compliance and Certification
Supports conformity with national and international fire safety regulations by providing a standardized test method accepted by CENELEC members across Europe.Public and Commercial Building Safety
Used for cable selection in buildings, transport infrastructure, and industrial installations where minimizing smoke generation is critical for evacuation and emergency response.
