The Australian Standard AS 1815 describes how often (frequency) the routine service of fire protection systems and equipment should occur. The term tolerance was also included in the Standard to provide guidance to readers on the allowable maximum and minimum duration between the frequency of routine service activities.
The introduction of a tolerance was added to the Standard to encourage the consistency of when a routine service activity should occur, as well as to discourage missed routine service activities. Later the use of tolerance has been used as a key performance indicator to manage fire services contractor performance.
Frequencies of Services
The frequencies adopted in this standard are set out in the applicable table to the right. Tolerances shall be applied to the interval from the date of the previous activity. Tolerances shall be applied in such a manner that the maintenance interval does not progressively extend beyond the required frequency specified in the table.
