European building electrical systems and safety-critical enclosed environments where post-fire air quality, occupant evacuation visibility, and structural corrosion control are life-safety requirements—modern hospitals, healthcare facilities, and medical-gas distribution systems where corrosive HCl decomposition products would compromise equipment and cause secondary patient harm, public buildings and educational institutions where rapid evacuation demands maintained visibility and non-toxic air conditions, enclosed machinery rooms and industrial control centers where cable fire-gas toxicity poses unacceptable occupant health risk, cable-tray installations in high-density multi-cable environments where individual cable flame-spread and bundle-flame-spread characteristics are critical, renewable-energy installations where grid-interconnection standards mandate halogen-free and low-smoke cable specifications, and European construction sites across all EU member states where CPR UE 305/11 construction products regulation and EN 50575 halogen-free specifications are mandatory for all electrical installation materials—demand advanced fire-safe control cabling engineered with complete elimination of halogenated compounds (chlorine, bromine, fluorine) that simultaneously achieve the complete spectrum of European fire-safety, electrical-code, environmental-compliance, and life-safety requirements that conventional PVC and standard rubber control cables cannot jointly deliver.

1. Halogen-Free Polymer Chemistry: Type TI6/TM7 Zero-Halogenated Formulation & HCl Suppression Engineering
GAALFLEX® CONTROL 500 H employs Type TI6/TM7 halogen-free polymer formulation that eliminates all halogenated compounds (chlorine, bromine, fluorine) from both insulation and outer sheath, preventing HCl gas generation during thermal decomposition and ensuring zero-corrosive-gas emissions during cable burning.
1.1 Halogen Elimination: Why Zero Chlorine Prevents HCl Gas Release
Standard PVC chemistry: PVC backbone contains ~57% chlorine by mass. During thermal decomposition (fire), C-Cl bonds break, releasing atomic chlorine that reacts with hydrogen in polymer chain to form HCl gas. HCl is extremely corrosive, highly toxic to humans, and causes secondary damage to electronic equipment and structures.
Halogen-free formulation approach (GAALFLEX CONTROL 500 H): Type TI6/TM7 employs exclusively halogen-free base polymers (low-density polyethylene, chloroprene rubber, or specialized elastomer blends) with no chlorine, bromine, or fluorine atoms in chemical structure. Result: Zero HCl gas generation, zero corrosive-gas production during burning.
Post-fire corrosion elimination: Electronic equipment exposed to HCl gas exhibits rapid corrosion of copper traces, solder joints, and connector pins—often rendering equipment permanently inoperable. Halogen-free cable eliminates this post-fire damage mechanism, preserving equipment and enabling critical system recovery.
Halogen-free decomposition (GAALFLEX CONTROL 500 H): Base polymer: Halogen-free elastomer, polyethylene, or chloroprene-free compounds No C−Cl bonds in polymer backbone High-temperature decomposition: Produces CO₂, H₂O, and inert hydrocarbons Zero HCl generation (chlorine absent from structure) Result: Zero corrosive-gas emissions per IEC 60754-2
Post-fire equipment exposure test (IEC 60754-2): Halogenated cable (PVC): Corrosivity rating ≥2 (severe—equipment damage expected) GAALFLEX H halogen-free: Corrosivity rating ≤1 (minimal—negligible equipment damage) Halogenated polymer decomposition and HCl generation mechanisms are extensively documented in fire-chemistry and polymer-science literature, with standardized testing per IEC 60754-1 (halogen determination) and IEC 60754-2 (corrosivity evaluation) [1,2,3].
2. Multi-Standard Flame-Spread Testing: IEC 60332-2-1 (Single Cable) vs. IEC 60332-3-24/3-25 (Bundle Flame-Spread)
GAALFLEX® CONTROL 500 H satisfies both single-cable flame-spread (IEC 60332-2-1) and cable-bundle flame-spread (IEC 60332-3-24/3-25) testing standards, ensuring fire safety in both isolated and high-density multi-cable installations.
Single-cable testing (IEC 60332-2-1): Individual cable suspended vertically, flame applied to bottom. Cable must self-extinguish and not allow flame propagation beyond 60 cm. Addresses scenario where single cable in duct or conduit catches fire.
Bundle flame-spread testing (IEC 60332-3-24/3-25): Multiple cables arranged vertically in bundle (simulating cable tray or conduit with many cables). Flame applied to bottom bundle. Bundle must not propagate flame to top of bundle (2-meter height) and must meet smoke and heat release limits. Addresses realistic scenario of fire in high-density multi-cable environment (industrial panel, building riser).
GAALFLEX CONTROL 500 H advantage: Certification to both standards ensures safety in isolated single-cable routing and in dense multi-cable installations. Many competitor cables pass single-cable test but fail bundle test—GAALFLEX H passes both.
3. Zero-Corrosive-Gas Architecture: IEC 60754-1/2 Compliance & Post-Fire Air-Quality Optimization
GAALFLEX® CONTROL 500 H achieves zero-corrosive-gas emissions per IEC 60754-1 (halogen determination) and IEC 60754-2 (corrosivity assessment), eliminating HCl, HBr, and other acidic-gas emissions that compromise post-fire building evacuation and cause secondary equipment damage.
IEC 60754-1 halogen determination: Cable material burned in controlled combustion chamber. Released gases absorbed in water. Conductivity of solution measured to determine halogen concentration. GAALFLEX H: <20 ppm total halogens (well below 50 ppm limit for "zero-halogen" designation).
IEC 60754-2 corrosivity assessment: Cable burned; decomposition gases passed over copper and silver strips. After exposure, metals examined for corrosion. GAALFLEX H achieves minimum corrosivity rating—negligible metal corrosion, no secondary damage to equipment.
Life-safety implication: In hospital fire, GAALFLEX H cables produce non-toxic, non-corrosive gases. Evacuating patients and staff not exposed to HCl fumes. Post-fire, equipment recovers without requiring replacement due to corrosion damage.
