Definitions for "Unavailability"
The test for determining deductions from the unitary payment by reference to the availability of the facility.
Availability can be defined as the probability that an item will operate correctly at a given time and under specified conditions. Numerical values associated with the calculation of availability are often awkward, consisting of a series of 9's before reaching any significant numerical information (e.g. 0.9999999654). For this reason, it is more convenient to use the complement measure of availability, namely, unavailability.
Situation in which a contaminant is sequestered from the microorganism, inhibiting the organism's ability to degrade the contaminant.
