Serialization Time at 14% traceability record allowance: a worked example

Push traceability record allowance up to 14% and the picture changes. This example computes every intermediate figure at that operating point. Use it when planning serial-number marking and records for cylinders, valves, extinguishers, control panels, detectors, or safety devices.

The inputs for this scenario

  • Devices requiring serial numbers: 600 devices (unchanged)
  • Devices serialized per hour (accepted): 120 devices / hr (unchanged)
  • Traceability record allowance: 14 % (raised for this scenario; the documented default is 12)

Working through the calculation

  • Applying the documented formula (Base serialization time = devices requiring serial numbers รท accepted devices serialized) to the inputs above produces each figure below.
  • At this operating point the engine returns 5.7 hr for required serialization time, the number this scenario is built around.
  • At this operating point the engine returns 5 hr for base hours before allowance.
  • At this operating point the engine returns 14 % for traceability record allowance.
  • At this operating point the engine returns 120 devices / hr for accepted devices serialized.

How this compares with the baseline

  • Against the tool's baseline example, where traceability record allowance sits at 12% and the headline result is 5.6 hr, this scenario comes in 1.79% above the baseline at 5.7 hr.
  • It computes the labor-hours needed to serialize a defined batch of fire-protection devices at a known accepted throughput, then inflates that base time by a traceability record allowance for verification and logging overhead. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Required serialization time: 5.7 hr (headline result)
  • Base hours before allowance: 5 hr
  • Traceability record allowance: 14 %
  • Accepted devices serialized: 120 devices / hr
