Every year before recertification starts, we query the Technical Committees to find out if there are any changes that need to be made to the current discipline Required Instrumentation lists that are on the NEBB website. This year, there will be changes made to the Sound, Vibration, CPT Option-2, and Retro-Commissioning instrument requirements. Here is a summary of these changes:
Sound Instruments
- Remove anything on the Master List that pertains to Real-Time Analyzers.
- In Appendix A – 2.0 Notes:
- Add Smart Phone Note.
- Remove Vibration notes and add them to the Vibration Instrument Requirement Sheet.
Vibration Instruments
- Add notes that were removed from the Sound Appendix A – 2.0 Notes to the Vibration Instrument Requirements Sheet as notes #9 and #10.
- Under Accelerometers / Transducers, add “or greater” after Measurement Range = +/- 20 G Peak.
- Vibration Note #9, change “No Longer” to “NOT.”
- Frequency Resolution – delete (Bandwidth).
- Frequency Range – change to “at least 1 to 1000 Hz (60 to 60,000 RPM).”
CPT Option 2
- Remove the sentence, “A Low Output (defined as one which supplies of < 5 x 10-9 particles / min of ≥ 0.3 um in size) or a normal output generator may be used.”
Retro-Commissioning
- The Range and Accuracy for the Carbon Monoxide (CO) Data Logger has been changed from a Range of 0 PPM to 1000 PPM to 3 PPM to 1000 PPM and an Accuracy of +/- 3 PPM to +/- 7 PPM. Background: The Lascar CO meters with a range of 0-1000 Range that was being used cannot be recalibrated. Lascar makes a new CO meter, ELUSB-CO, that has a range of 3-1000 PPM. This is the new value that will be added to the Instrument Requirement List, along with increasing the accuracy from +/- 3 PPM to +/- 7 PPM. That way, both the new and older Lascar meters meet the requirements.
These changes will be found on the Instrument List (Effective January 1, 2024) when it is placed on the NEBB website before the next recertification cycle begins.
