3.1

absorbed energy

q_net

net energy (3.7) absorbed by the sensor that accounts for all modes of heat transfer interacting with the sensor surface when exposed to the incident energy (3.16)

Note 1 to entry: The energy balance including losses unique for each sensor type are detailed in the respective sensor technology documents.

Note 2 to entry: See Figure 1 in 4.2 for a schematic representation of this definition.

3.2

associated area

area of body region per sensor

Note 1 to entry: See Table 3.

3.3

data acquisition period

time elapsed during which data is recorded during a test

3.5

data calculation period

defined time over which data are used for a calculation

3.6

conditioning

keeping samples under standard conditions of temperature and relative humidity for a minimum period of time

3.7

energy

heat flux (3.13) integrated over a specified time period multiplied by associated area (3.2)

Note 1 to entry: Energy is expressed in joules (J).

3.8

exposure duration

exposure time

time from the initial opening of the valves nearest to the burner to the closing of the same valve (8.2.6.)

3.9

exposure heat flux

incident heat flux averaged among the manikin sensors during data calculation period

3.10

fire

rapid oxidation process which is a chemical reaction of fuel and oxygen resulting in the evolution of light, heat and combustion products in varying intensities

Note 1 to entry: The fuel can be a form of solid, dust, aerosol or a gas of an ignitable substance. The fire will last as long as there is a combustible fuel-air mixture.

3.11

flame distribution

spatial distribution of the flame engulfment from the test facility burners which provides a controlled exposure heat flux (3.9) over the manikin surface

3.12

garment ease

difference between body (manikin) dimensions and garment dimensions

3.13

heat flux

heat through a surface area perpendicular to the direction of heat flow

Note 1 to entry: Heat flux is expressed in kW/m². For any conversion from kW/m² to cal/cm².s; the following ratio is to be used 4,184 J = 1 cal.

3.13.1

absorbed heat flux

net heat flux (3.13) absorbed by the sensor that accounts for all modes of heat transfer interacting with the sensor surface when exposed to the incident heat flux (3.13.2)

3.13.2

incident heat flux

heat flux (3.13) to which a test item or sensor is exposed

Note 1 to entry: for incident heat flux to manikin sensors, see fig on energy balance (4.2)

3.14

heat flux sensor

manikin sensor

device, fulfilling the requirements of this document, capable of measuring the heat flux (3.13) to the manikin's surface under test conditions, or of providing data that can be used to calculate the heat flux

3.15

incident energy

energy (3.7) to which a sensor is exposed during a nude exposure (3.18)

3.15.1

total incident energy

sum of the incident energy (3.16) of a specified set of manikin sensors (3.15) during the nude exposure for the specified time period

3.16

instrumented manikin

model representing an adult-sized human (male or female) which is fitted with manikin sensors (3.15) in the surface

3.17

nude exposure

test performed on the uncovered surface of the instrumented manikin (3.17)

3.18

maximum absorbed heat flux

highest value of absorbed heat flux (3.13.1) calculated from the recorded output of a manikin sensor (3.15) during a test

3.19

transferred energy

absorbed energy (3.1) by a single sensor under the test item

Note 1 to entry: Each manikin sensor has an associated area (3.2) . It is assumed that the measured energy transferred for each manikin sensor is uniform over this associated area. Some manikins have a sensor layout that has the same area associated with each manikin sensor, others do not.

3.19.1

total transferred energy

sum of the transferred energy (3.20) of a specified set of covered manikin sensors (3.15) over the data calculation period (3.5)

Note 1 to entry: Total transferred energy can refer to either the whole covered area of the manikin or to a specific covered manikin region.

3.20

thermal manikin protection factor

TMPF

factor representing the overall protective garment or ensemble performance as a function of exposure and test specimen mass
