Overview

EN 60754-2:2014/A1:2020 (equivalent to IEC 60754-2:2011/A1:2019) is a CENELEC-adopted test-method standard for assessing gases evolved during the combustion of cable materials. It specifies procedures to determine acidity (by pH measurement) and conductivity of the absorption solution produced during cable combustion. Amendment A1 updates test apparatus, sampling and analytical requirements and aligns the heating/combustion procedure with IEC 60754-3.

Key topics and technical requirements

• Scope and linkage
  • Part 2 is linked with IEC 60754-1 (halogen acid gas content) and IEC 60754-3 (low-level halogen measurement by ion chromatography). The absorption solution generation procedure is the same as IEC 60754-3.
• Combustion procedure
  • Heating/combustion follows the method used in IEC 60754-3.
• Air flow and supply
  • Air flow rate formula specified: ρ = 20 m/h × (π/4) × D × 10 with ±10% tolerance (D = internal diameter of the quartz tube). Examples are provided for D = 30 mm and D = 46 mm.
  • Methods cover synthetic/compressed air and ambient air drawn by pump; updated Figures 3–5 define apparatus layouts.
• Specimen and weighing
  • Combustion boats and specimens are weighed using an analytical balance with resolution and accuracy of ±0.1 mg (measurements in mg rounded to one decimal place).
• Laboratory glassware
  • Specified replacement: ISO 1042 Class B glassware.
• Washing and sample preparation
  • Clarified washing procedure and final volume reference (“made up to the 1 000 ml mark”).
• Statistical acceptance
  • Rules for repeat testing when coefficient of variation > 5%: additional three tests and recalculation of mean, standard deviation and coefficient of variation in reporting against performance requirements.

Practical applications and users

• Cable manufacturers and raw-material suppliers use the standard to characterize combustion by-products from polymeric cable materials.
• Independent testing laboratories adopt EN 60754-2:2014/A1:2020 for routine pH and conductivity testing of combustion condensates to support product safety declarations.
• Specifiers, safety engineers and procurement teams use results to evaluate cable suitability for enclosed spaces, transportation, rail, marine or building installations where acidic combustion products and conductivity are safety concerns.
• Regulators and conformity assessment bodies reference the standard when assessing compliance with fire performance requirements.

Related standards

• EN / IEC 60754-1 - determination of halogen acid gas content
• IEC 60754-3 - measurement of low-level halogen content by ion chromatography

Keywords: EN 60754-2:2014/A1:2020, IEC 60754-2, test on gases evolved during combustion, acidity by pH measurement, conductivity, cable combustion testing, analytical balance ±0.1 mg.
