S actual safe working period
D theoretical safe working period
13 Measures to be taken at the end of the theoretical safe working period
13.1 Calculation of the theoretical safe working period
Establishing the kmi total load factor
Establishing the portion of the theoretical safe working period consumed in the specific period:
Actual use:
Si = kmi × T* × workdays × multiplier
Si = .. ... ×. ... × ............. ...... × ............
Si = h - number of hours at full load
Establishing the total consumed portion of the theoretical safe working period:
S = Si (specific period) + Si (all previous periods)
S = ........................................ + ...............................
S = h
Establishing the theoretical safe working period
in accordance with FEM 9755:
The ratio of the actual and the theoretical safe working period must be ≤ 1.
= = = ≤ 1
Residual safe working period: D - S = .................. - .................. = h
Upon reaching the theoretical safe working period the machine or its components must be
subjected to a general overhaul, or must be disposed of as waste in an environmentally
sound manner.
13.2 Disposal
Lubricants such as oils and greases must be disposed of in compliance with the effective Act on waste. Metals,
rubber, and plastics must be forwarded for recycling separately.
