Icom Quality and Reliability SOLAR RADIATION (SUNSHINE) METHOD 505.4 To determine the heating effects of direct solar radiation on radios. And to help identify the actinic (photodegradation) effects of direct solar radiation. • Procedure I - Cycling (heating effects). Use Procedure I to investigate response temperatures when radios is exposed in the open in realistically hot climates and is expected to perform without degradation during and after exposure. RAIN METHOD 506.4 The purpose of this method is to help determine the effectiveness of protective covers, cases, and seals in preventing the penetration of water into the radios. Also the capability of the radios to satisfy its performance requirements during and after exposure to water. • Procedure I - Rain and Blowing Rain Procedure I is applicable for radios which will be deployed out doors and which will be unprotected from rain or blowing rain. • Procedure III - Drip. Procedure III is appropriate when the radio is normally protected from rain but may be exposed to falling water from condensation or leakage from upper surfaces.

SOLAR RADIATION (SUNSHINE)
METHOD 505.4
To determine the heating effects of direct solar radiation
on radios. And to help identify the actinic
(photodegradation) effects of direct solar radiation.
• Procedure I – Cycling (heating effects).
Use Procedure I to investigate response temperatures
when radios is exposed in the open in realistically hot
climates and is expected to perform without degradation
during and after exposure.
RAIN
METHOD 506.4
The purpose of this method is to help determine the
effectiveness of protective covers, cases, and seals in
preventing the penetration of water into the radios. Also
the
capability of the radios to satisfy its performance
requirements during and after exposure to water.
• Procedure I - Rain and Blowing Rain
Procedure I is applicable for radios which will be deployed
out doors and which will be unprotected from rain or
blowing rain.
• Procedure III - Drip.
Procedure III is appropriate when the radio is normally
protected from rain but may be exposed to falling water
from condensation or leakage from upper surfaces.
