Introduction

This test method provides a measurement instrument of the dummy and compare different materials, different clothing and flame-retardant protective clothing matching properties method. However, this test method can not be used as a quality assurance test, it does not involve impact dummy body posture and movement of the test results.

Thermal Protective Performance Measurement clothing more complex, depending on the test results using the instruments and techniques. Established in the field that contains all Test methods may occur accident state is unrealistic. Difference test methods can lead to large differences in the test results. Such as If the description given in this test method has obvious bias, we need to heat transfer theory and technical knowledge and practices related test was evaluated price. Standardized test method can reduce but not eliminate the errors caused by the above-mentioned technical knowledge. Test results should report all difference.

Retardant clothing evaluate performance under the conditions of flashover dummies Test Method

1 Scope

This standard specifies the lower heat flux, distribution and duration of the flame can be controlled flashover simulation environment, characterization protective clothing flame retardant Quantitative measurements and subjective methods of observation.

This standard applies to testing and evaluation of protective clothing flame retardant properties, it can also be used to predict the degree of body tissue burns and total area burned.

NOTE. This standard applies to measure and describe the material, product or composition under controlled conditions in response to heat and flame, and it should not be used to describe and evaluate the material Material, product or composition in the actual scene of the fire hazards and possibilities. But with the results of this standard test can be used as a fire or ignition hazard assessment Based on a risk assessment, the assessment of the relevant factors to consider in particular the use of fire hazard or fire risk assessment.

3 Terms and Definitions

GB/T 3291, GB/T 13640 and identified by the following terms and definitions apply to this standard.

Human tissue at different depths thermal damage.

NOTE. When human tissue is heated and persist for some time, the tissue will burn at high temperatures. Burns were divided into first-, second- and third-degree burn three Level injury; burns depends on the temperature level and the length of duration.

In the clothing flashover test, controllable heat flux ejected from the burner flame in the spatial distribution of the dummy surface.

Has adult size, surface laid at least 100 heat sensors used in clothing flashover test dummies.

Test measurements of heat transferred to the surface of a dummy instrument (device).

For the detection of a single piece of clothing or an attribute set of protective clothing to prevent burns to produce heat transfer properties.
