Aerospace series - Cables, electrical, aircraft use - Test methods - Part 602: Toxicity
This test method is intended for use in determining the concentration of specific gas components of smoke released by cable insulation materials.
This test method should be used to measure and describe the properties of cable insulation materials in response to heat and flame under controlled laboratory conditions.
This standard should be used to measure and describe the properties of products in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.

Overview
EN 3475-602:2007 - part of the aerospace series for electrical cables - specifies a laboratory test method for toxicity by measuring concentrations of specific gas components in smoke released from cable insulation materials. It defines controlled sampling and analytical procedures (colorimetric and potentiometric) to quantify non‑reactive and reactive smoke gases under the same conditions used for smoke density testing (see EN 3475‑601). This standard is for material characterization and input to fire risk assessments, not a direct measure of real‑world fire hazard.
Key topics and technical requirements
- Scope and limits
- Measures concentrations of targeted smoke gas components under controlled heat/flame conditions.
- Results are not intended to appraise actual fire hazard but may inform fire risk assessments.
- Sampling system
- Probes: three probes (6–8 mm internal diameter) placed at chamber center; materials resistant to halogenides (polypropylene, PTFE).
- Two collection options for non‑reactive gases: vacuum or suction pump filling of foil gas bags (recommended 10–15 L capacity, PVDF foil).
- Pipe requirements: inner diameter 6–8 mm, recommend PTFE for corrosive/temperature exposure; insulation to prevent condensation.
- Analytical methods
- Colorimetric (in situ): test tubes with solid reagents; discoloration length correlates with concentration. Used for relatively non‑reactive gases (e.g., HCl, HF via specific tubes).
- Potentiometric (wet analysis): absorption into solution (impinger bottle) followed by ion‑specific electrodes to quantify halogenides (F−, Cl−, Br−). Calibration to convert potentials to ppm.
- Operational controls
- Specified sample volumes and flow rates (e.g., 1 000 cm3 sample through impinger, max suction 2 000 cm3/min for potentiometric sampling); vacuum tank sizing (≈15 L) and bag filling performance (fill within ~20 s).
- Daily checks: leakage tests, probe cleanliness, chamber conditioning (pre‑tests required because HF adsorbs to chamber walls).
Applications and users
- Who uses it:
- Aerospace cable manufacturers and material suppliers for product characterization and qualification.
- Independent test laboratories performing aircraft cable toxicity testing.
- Design engineering and safety teams conducting fire risk assessments or specifying low‑toxicity cable materials.
- Certification and procurement bodies requiring documented test evidence.
- Practical uses:
- Compare insulation formulations for reduced toxic smoke components.
- Provide quantitative inputs (ppm levels of HCl, HF, HBr, etc.) for multidisciplinary fire safety assessments.
- Support R&D, supplier qualification, and material selection for aircraft interiors and systems.
