ISO 6942 Thermal Protective Radiation Performance Tester EN 366

The Thermal Radiation Protective Performance Tester is designed to evaluate the thermal radiation protection provided by protective materials, in compliance with standards such as ISO 6942 and EN 366. The instrument supports two test methods: Method A, which involves a visual assessment of changes in the material's appearance following exposure to thermal radiation; and Method B, which determines the material's thermal protective performance by measuring the Radiant Heat Transfer Index (RHTI) — defined as the time required for the temperature on the reverse side of the specimen to rise by 12°C or 24°C.

• EN (European Standards): EN ISO 6942, EN 1363, EN 366
• ISO (International Organization for Standardization): ISO 6942
• Other Standards: AQ 6103

• The test apparatus consists of a radiation unit, a specimen holder, and a data acquisition and software system.
• The thermal radiation unit comprises six Glowbar heating elements, capable of operating at temperatures of at least 1100°C.
• The specimen clamping mechanism utilizes a circulating water cooling system for protection.
• A copper disc calorimeter made of oxygen-free superconducting copper is used to measure thermal radiation flux.
• The specimen holder is horizontally adjustable, allowing for thermal radiation flux measurements at various positions.
• A weight mechanism is included to apply a standard 2N force to the specimen.
• The data acquisition system records parameters such as thermal radiation flux, temperature, and time.
• Equipped with a computer and printer for data output and test report printing.
