Category 3 Vibration (From ISO 18436-2)

Personnel classified to category III require all the knowledge, experience and skills expected of personnel classified to categories I and II, and in addition shall at least:
a) be able to design, direct and establish routine condition monitoring programs and non-routine
investigations for the purpose of fault diagnosis;

b) be able to specify the appropriate vibration instrumentation hardware, software, and processing
for portable monitoring systems, permanently installed surveillance systems, and equipment
protection systems

c) have an in-depth knowledge of the principles and techniques of machinery VA and be able to makeinitial diagnoses of suspected faults beyond the range of commonly encountered issues. This should include, but not be limited to, the use of frequency spectra, time waveforms and orbits, transfer
functions, basic operating deflection shapes, and acceleration enveloping under both steady state
and transient conditions with or without a phase trigger;

d) be able to manage such condition-monitoring programs, evaluate the alarm sets, write working
procedures and specify vibration acceptance testing procedures;

e) be able to initiate and validate machinery corrective actions including in situ two-plane rigid rotor

f) be able to recommend restrictions to machine operation;

g) be able to understand and direct, when necessary, alternative condition monitoring technologies to verify or investigate issues raised through routine data collection;

h) be able to provide technical guidance to and instruct category I and II personnel, and, subject to
agreement with the employer or client, deem them competent to carry out certain duties which
would normally be outside the scope of those competencies.

It is the responsibility of the employer or client to ensure that category III personnel have the necessary
competency in the required management skills, e.g. creating budgets, preparing cost justifications, and
managing personnel development
