Technical Definitions
Chapter 1: Introduction
Technical Definitions
This manual contains different technical terms. Note the following definitions:
Incubator temperature—The air temperature at a point 4" (10 cm) above
and centered over the mattress surface.
Control temperature—The temperature controller’s set point selected by
the user.
Average incubator temperature—The average of the maximum and
minimum incubator temperatures achieved during temperature
equilibrium.
Incubator temperature equilibrium-—The condition reached when the
average incubator temperature does not vary more than 1°C over a period
of one hour. These measurements are taken at the control temperatures of
90°F (32°C) and 97°F (36°C).
Temperature uniformity—The amount by which the average temperature
of each of four points 4" (10 cm) above the mattress surface differs from
the average incubator temperature at incubator temperature equilibrium.
Temperature rise time—The time required for the incubator temperature
to rise 20°F (11°C), when the air control temperature is at least 22°F
(12°C) above the ambient temperature.
Temperature overshoot—The amount by which incubator temperature
exceeds average incubator temperature at incubator temperature
equilibrium as a result of an increase in control temperature. Additionally,
the incubator temperature equilibrium shall be restored within 15 min as a
result of an increase in control temperature value.
Temperature correlation: Incubator temperature versus control
temperature—The amount the air temperature indicator at incubator
temperature equilibrium differs from the control temperature.
Temperature correlation: Temperature indicator versus control
temperature—The amount the air temperature indicator in air mode at
incubator temperature equilibrium differs from the control temperature.
Measurement points-—Measurements are taken at five points in a plane
parallel to and 4" (10 cm) above the mattress surface (see figure 1-5 on
page 1-7). One point is 4" (10 cm) above the center of the mattress; the
remaining four points are the centers of four areas formed by lines that
divide both the width and length into two parts.
