Measurement of smoke density of cables burning under defined conditions - Part 1: Test apparatus

This part of IEC 61034 provides details of the test apparatus to be used for measuring smoke emission when electric or optical fibre cables are burnt under defined conditions, for example, a few cables burnt horizontally. The light transmittance (l t ) under flaming combustion and smouldering conditions can be used as a means of comparing different cables or complying with specific requirements.

Overview

SIST EN 61034-1:2005/A1:2014 is a European standard focused on the measurement of smoke density produced by cables burning under defined conditions. Developed and maintained by the CLC (European Committee for Electrotechnical Standardization), this standard specifies the test apparatus requirements used to evaluate smoke emission due to cable combustion. It supports safety objectives related to fire hazards in electrical installations by providing a consistent methodology to assess cable smoke density.

This amendment (A1) to the original EN 61034-1:2005 was approved in 2013 and published in 2014, ensuring alignment with the latest technical and regulatory needs. Although the standard is maintained as a supporting document, its application remains essential for manufacturers, testers, and regulatory bodies concerned with fire safety and product compliance in the electrical cables industry.

Key Topics

• Test Apparatus Design
  SIST EN 61034-1:2005/A1:2014 outlines the technical specifications for the testing apparatus used to measure smoke density. The standard ensures the device's optical and mechanical components meet stringent accuracy and reproducibility criteria.

• Smoke Density Measurement
  The methodology involves burning cables under defined controlled conditions and quantifying the smoke density by measuring light transmittance through the smoke. Key parameters such as initial and minimum transmittance levels are used to compute smoke density.

• Qualification of Fire Sources
  The amendment refines preparation of the fire source mixtures using PA toluene and alcohol solutions, specifying proportions and preparation methods to guarantee consistent ignition and flame behavior during tests.

• Test Procedure and Data Calculation
  Detailed instructions for conducting the smoke density test and how to record the minimum measured transmittance for accurate evaluation. The amendment clarifies formulae used to calculate smoke density from transmittance readings.

• Optical System Corrections
  Minor corrections and clarifications on the wording related to the optical system components-critical for test reliability.

Applications

• Cable Fire Safety Testing
  SIST EN 61034-1:2005/A1:2014 is essential for manufacturers and testing laboratories conducting compliance evaluations of electrical cables against fire safety standards. It helps assess the hazards related to smoke obscuration during cable fires.

• Product Development and Certification
  Cable producers use this standard to optimize formulations and construction techniques for low smoke emission cables. Compliance supports product certification and market approval within the EU and other regions referencing CENELEC standards.

• Building and Electrical Codes Compliance
  Regulatory bodies reference this standard in electrical installation codes where fire safety and smoke emission performance of cables are critical to occupant safety and emergency response.

• Risk Assessment in Fire Situations
  Facilities management and safety engineers utilize test data based on this standard to evaluate building fire risks and plan mitigation strategies involving cable routing and materials.
