Overview

EN ISO 13506-1:2024 - Protective clothing against heat and flame - Part 1: Test method for complete garments - Measurement of transferred energy using an instrumented manikin - specifies a laboratory test method to quantify thermal protection of complete garments and ensembles exposed to short‑duration flame engulfment. The method measures heat transfer to a full‑size instrumented manikin under controlled convective and radiant energy, producing transferred energy and Thermal Manikin Protection Factor (TMPF) results that characterise single‑layer and multi‑layer flame‑resistant clothing.

Key factual limits:

• Exposure heat flux: nominally up to 84 kW/m²
• Exposure durations: 3 s to 20 s, chosen according to risk assessment and garment insulation
• Results apply only to the specific garments and test conditions used

Note: the method does not simulate high‑radiant exposures (e.g., arc flash), many liquid/solid fuel fires, or nuclear explosions. It is a complex procedure requiring high technical expertise; small deviations can significantly change results.

Key Topics and Requirements

• Instrumented manikin: full‑size manikin with distributed heat‑flux/temperature sensors; sensor positioning, specification and validation are specified.
• Heat flux control & measurement: incident and exposure heat flux determination, energy balance on sensors, and data correction methods.
• Apparatus: detailed requirements for manikin, flame exposure chamber, fuel and burner systems, data acquisition, and image recording.
• Calculation methods: summation of heat transfer over prescribed time to compute transferred energy and TMPF; software and calculation routines are defined.
• Test procedure & documentation: specimen preparation (conditioning, optional laundering), dressing procedure, test sequence, visual evaluation before/during/after exposure, and reporting templates.
• Safety & laboratory competence: chamber safety devices, purging, fuel shut‑off, and laboratory capability demonstration.
• Limitations: body motion effects are not addressed; results are valid only for tested configurations and specified heat flux/duration/flame distribution.

Practical Applications

• Performance evaluation and comparative ranking of flame‑resistant garments and ensembles
• Product development and R&D to optimise fabric/system thermal resistance
• Conformity assessment and type‑testing by PPE test laboratories and certification bodies
• Procurement specifications for protective clothing in industries with flash/fire risk (oil & gas, petrochemical, firefighting support, heavy industry)
• Incident and risk assessment studies where short‑duration flame engulfment scenarios are relevant

Who Should Use It

• PPE manufacturers and designers of heat‑/flame‑resistant garments
• Accredited test laboratories and conformity assessment bodies
• Safety engineers, procurement officers, and regulatory authorities specifying protective clothing performance
• Research organisations developing thermal protection metrics and models

Related Standards

• ISO 13506-2 (for calculating predicted skin burn from measured heat flux)
• Developed by ISO/TC 94 and adopted by CEN (CEN/TC 162)
