Inspection Categories
6.3.1
Inspection Category I
Observe the PS-500 during operation. Recognizing
inadequate performance and apparent defects is the goal
of this category.
Scope/Prerequisites/Procedure:
- Daily visual inspection of the PS-500 for damages and
defects during operation. Repair them if necessary.
- Functional test.
- A person with appropriate expertise must carry out the
test.
6.3.2
Inspection Category II
The inspection of category II includes all inspections of
inspection category I and additional tests.
Scope/Prerequisites/Procedure:
- Checking the state of lubrication, the condition of the
entire PS-500 and the settings of all valves.
- A person with appropriate expertise must carry out the
test.
6.3.3
Inspection Category III
The inspection of category III includes all inspections of
inspection category II and additional tests.
Scope/Prerequisites/Procedure:
- Non-Destructive Testing (NDT) of selected critical areas
and verification of all wear limits.
- Before carrying out an NDT test, remove all foreign
material such as dirt, paint, lubricants, oil and abrasion
from the affected parts. Use suitable methods such as
pickling, steam cleaning and sandblasting.
6.3.4
Inspection Category IV
The inspection of category IV includes all inspections of
inspection category III and additional tests.
Scope/Prerequisites/Procedure:
- Before carrying out an NDT test, remove all foreign
material such as dirt, paint, lubricants, oil and abrasion
from the affected parts. Use suitable methods such as
pickling, steam cleaning and sandblasting.
- Non-destructive material testing (NDT) of all critical
areas and replacement of selected consumables and
hydraulic components.
