Vibration Standards & Safety Flashcards

Which ISO standard provides general procedures for vibration condition monitoring of machines, including measurement and data collection guidelines?

Answer: ISO 13373-1

ISO 13373-1 gives general procedures for vibration condition monitoring of machines.

ISO 2954 specifies requirements for which item?

Answer: Instruments for measuring vibration severity on rotating and reciprocating machines

ISO 2954 defines requirements for vibration severity measuring instruments, including frequency response.

Which standard defines vocabulary and terminology for mechanical vibration, shock, and condition monitoring?

Answer: ISO 2041

ISO 2041 is the vocabulary standard for mechanical vibration, shock, and condition monitoring.

ISO 13381-1 provides guidance on which aspect of condition monitoring?

Answer: Prognostics, estimating remaining useful life

ISO 13381-1 covers general guidelines for prognostics in condition monitoring and diagnostics of machines.

Before opening an energized motor terminal box to take current measurements for motor diagnostics, which US standard defines required arc-flash PPE and approach boundaries?

Answer: NFPA 70E

NFPA 70E defines electrical safety practices including arc-flash boundaries and PPE categories.

An analyst baselines a new pump at 1.0 mm/s RMS. ISO 10816-3 Zone B/C for this machine is 2.8 mm/s. Following the standard's guidance (baseline plus 25% of the B/C limit), what alarm value is appropriate?

Answer: 1.7 mm/s

1.0 + 0.25 x 2.8 = 1.7 mm/s, which also stays below 1.25 x 2.8 = 3.5 mm/s.

When collecting route data near large operating machines, which practice best reduces the risk of slips and entanglement?

Answer: Securing cables, keeping ID badges and lanyards tucked away, and watching footing near oil and steps

Secured cables, tucked loose items, and attention to footing prevent common entanglement and fall hazards.
