Product Description:

Protective clothing Flame Resistance Tester: Thermal protection (radiation) performance testing in accordance with ISO6942 and EN366 standards of design and manufacturing. This tester fully compliant to test requirements and received US and European customers’ acception; The device has a user-friendly, intuitive, Windows-based application that provides a complete thermal control, fault detection and data recording. RPP system configuration and burn prediction also included in the ThermDAC.

User-defined test allows the operator to define a non-standard test conditions and custom tolerances. You can view multiple graphs display with zoom feature to view specific conditions in details. Real-time statistics can be applied to the test data within any user selected time range.

This tester used for performance evaluation against heat and flame protective clothing when faced with short flame thermal motion.Imposed a certain calorie density (80KW/m2+/- 5%) of heat, under the specimens that composed of protective clothing. When measuring the growth rate of heat through over time (time: seconds, temperature: C) by heatmeter that installed on  test sample, to determine the insulation properties of sample materials.This apparatus is applied to measuring the fabric of single-layer or multi-layer under high temperature thermal radiation properties, can also be used for other fire-retardant insulation of plates.

Test Standards: EN 366, ISO 6942, ISO 11999-4

Product Features
