3 Environmental Capabilities
3.1 Scope
This chapter covers the environmental requirements for the indoor and outdoor
temperature non-controlled operation conditions. The subjects are: Climatic,
Biological, Chemically active substances, Mechanically active substances and
Mechanical conditions.
3.2 Terminology
Definition of concepts:
Normal Operation Conditions
Environmental conditions where all units shall be able to function as specified.
Safe Function
Environmental stress above the limits for normal operation where all units
shall continue to function during the stress, but performance or capacity may
be reduced.
Reduction of performance or capacity shall be documented as a typical value.
When the environmental stress has dropped to normal operation conditions,
function as specified shall automatically be achieved.
Safe function refers to an operation period of not more than 72 consecutive
hours, and a total of not more than 15 days in one year.
Non-destruction
Environmental stress above the limits for safe function during which no function
is guaranteed and performance may degrade in an unspecified manner.
When the environmental stress has dropped to normal operation conditions, no
manual intervention (on site) is needed to restore full performance of the RBS.
Non-destruction refers to an operation period of not more than 96 consecutive
hours, and a total of not more than 5.5 days in a 3-year period.
