Overview

SIST EN 61034-1:2005/A2:2020 is a European standard published by CLC that specifies the test apparatus for the measurement of smoke density produced by cables burning under defined conditions. As Part 1 of the EN 61034 series, this amendment (A2:2020) updates and refines the original 2005 standard, aligning with the international IEC 61034-1:2005/A2:2019 document. This standard plays a critical role in evaluating the smoke emission characteristics of cables, an important factor in fire safety and cable compliance testing.

The standard focuses exclusively on the test apparatus design and procedural elements required to reliably measure smoke density, ensuring repeatable and consistent test results. It is widely adopted by electrotechnical committees across Europe and relevant industries where cable performance under fire conditions requires rigorous assessment.

Key Topics

• Test Apparatus Configuration
  The standard details the specifications for the photometric system used to measure smoke density, emphasizing correct placement of the light source and receiver opposite each other through optical windows to ensure accurate light attenuation readings.

• Photometric System Adjustments
  A key update includes clarifications on calibration tolerances for optical filters, requiring parameter A to remain within ±5% of the calibrated value, ensuring reliable smoke density quantification.

• Standard Fire Source Specifications
  The amendment corrects terminology relating to components of the fire source, specifying “bottom” and “top” rather than “bottom base” and “top base,” and highlights the impact of tray material (galvanized steel vs stainless steel) on test results.

• Cube Preparation and Conditioning
  Guidance is provided on conditioning the interior test chamber (cube) to the required temperature range using blank tests prior to smoke density measurement, enhancing the accuracy and repeatability of smoke assessments.

• Qualification of Fire Sources
  Notes clarify how aging and material of fire source trays affect parameter A values, underpinning the importance of careful apparatus maintenance and selection in smoke density testing.

Applications

• Cable Fire Safety Testing
  SIST EN 61034-1:2005/A2:2020 is essential for manufacturers and testers assessing how cables behave when exposed to fire, particularly their smoke emission properties which impact visibility and toxicity in evacuation scenarios.

• Regulatory Compliance
  The standard supports compliance with national and European fire safety regulations where smoke density limits for cables must be demonstrated, helping ensure safer buildings and infrastructure.

• Quality Control for Cable Production
  Cable producers incorporate smoke density measurements into quality assurance protocols to verify product consistency and performance before market release.

• Research and Development
  R&D teams utilize the standard’s test apparatus framework to innovate low-smoke cable formulations and improve fire-resistant cable designs.

Related Standards

• EN 61034-2 – Measurement of smoke density of cables burning under defined conditions - Part 2: Test procedure
  Complements Part 1 by establishing procedural steps for conducting the smoke density tests using the apparatus.

• IEC 60332 Series – Tests on electric cables under fire conditions
  Addresses flame spread characteristics, often used in conjunction with smoke density measurements for comprehensive fire performance evaluation.

• EN 50575 – Construction products and building elements - Fire performance of construction products - Cables for general applications in construction works
  Relies on smoke emission data aligned with EN 61034 standards as part of harmonized European fire performance requirements.
