Introduction
The Radiant Protective Performance Test Device is used to determine the behavior of material for heat protective clothing subjected to heat radiant.The test is carried out on the representative single or multi-layer textiles, materials, or assemblies intended for clothing used in the protection against heat.
ISO 6942 defines two test methods for the radiant heat test.
| Method A |
The specimen is mounted in the specimen holder vertically and exposed to the specific radiant heat source for a time. Adjust the distance between the specimen and the radiant heat source, and examine the visible changes on the specimen for determining the behavior of the material for heat protective performance. |
| Method B |
The specimen is mounted in the specimen holder vertically and exposed to a specific level of radiant heat. Measure the time for the temperature sires of 12 degrees and 24 degrees by the calorimeter behind the specimen. The radiant heat transfer indexes, and percentage heat transmission factor are calculated from the temperature rise data and are served to evaluate the specimen heat protective performance. |
Features
1.The Radiant Protective Performance Tester consists of a radiant heat source, sliding test platform, specimen holder, copper plate calorimeter, data acquisition system, and operation software.
2.The radiant heat source consists of six Glowbar silicon carbide (SiC) heating rods, working temperature up to 1100 degrees.
3.The power of heating rods is supplied by two independent circuits three rods for each.
4.The power supplies of each circuit are with a voltage stabilizer for providing consist radiant heat source.
5.The sample holder is on the right side of the sliding test platform, and can slide to obtain different levels of radiant heat.
6.The specimen holder is stainless steel made and with thermal insulation for a precise test.
7.The curved plate calorimeter complies with ISO 6942, and consists of a CNC machined curved copper plate, insulation block, and thermocouple.
8.A 0.2mm copper constantan thermocouple is attached to the center of the copper plate for temperature measurement.
9.Provides tensioning device to apply a force of 2N on the sample.
10.Data acquisition system, used to record heat flux, temperature, and times.
11.Windows based operation software, provides standard test procedures.
