Equipment Calibration Log

Equipment calibration log for cannabis manufacturing and extraction facilities. Captures equipment master record, NIST-traceable standards used, multi-point calibration check readings (as-found and as-left), out-of-tolerance impact assessment on prior batches, and QA approval. Aligned with NJAC 17:30-11.3(c), 17:30-11.12(a)(6), and cGMP 21 CFR 211.68.

When to Use This Template

Complete this log on every calibration event — scheduled, post-repair, post-relocation, or when out-of-tolerance is suspected. Update the Next Calibration Due Date before filing. Physical calibration sticker on equipment MUST match the log. For out-of-tolerance findings: take equipment out of service immediately, initiate deviation/CAPA, and document retrospective impact on all product measured since last passing calibration.

What's Included

  • ✓Equipment Master Record (name, type, asset tag, serial, manufacturer, location)
  • ✓Calibration event metadata (event ID, date, reason, SOP reference)
  • ✓NIST-traceable standards section (cert #, expiration, last-NIST-cal date)
  • ✓Calibration Performed By: internal vs external; technician name + CBIC
  • ✓Multi-point calibration check repeating section (date, standard, as-found, as-left, pass/fail, initials)
  • ✓Calibration sticker update verification
  • ✓Out-of-Tolerance section: yes/no, impact assessment on prior batches, CAPA reference
  • ✓Next calibration due date + equipment status
  • ✓Top 5 CRC/cGMP deficiency callout
  • ✓Two-party signoff: Calibration Technician + QA Manager

Compliance Notes

Supports NJAC 17:30-11.3(c) (equipment inspection, maintenance, and validation at manufacturer-specified intervals) and NJAC 17:30-11.12(a)(6) (critical processes recorded and validated). Calibration record content follows NJAC 17:30-19.7(d) standard (applied by practice to manufacturer equipment): date, performer, SOP reference, deviations, repair details, result. cGMP analog: 21 CFR 211.68 (calibration per written program) and 211.182 (records maintenance). Reference standards must be NIST-traceable (per 21 CFR Part 820.72 / FDA expectations). For analytical balances used in potency measurement, miscalibration can cause THC limit violations against the 90–110% cannabinoid content tolerance in NJAC 17:30-11.5. Retain records for equipment life + 2 years minimum.

Frequently Asked Questions

How often should cannabis facility equipment be calibrated?

Frequency is equipment-specific and defined by your SOP. Industry-typical intervals: analytical balance — monthly calibration + daily verification; production scale — weekly verification + annual sealer; HPLC — daily performance check + monthly comprehensive; rotovap and vacuum gauges — quarterly; CO2 pressure transducers — every 3–6 months; temperature probes — quarterly; hydrocarbon LEL detectors — at least annually per NFPA 58. Document your SOP-defined interval in this log.

What qualifies as a NIST-traceable reference standard?

A reference standard whose calibration chain is documented back to the National Institute of Standards and Technology (NIST). The certificate must be current, on file, and traceable. The standard's accuracy must be at least 4× better than the equipment being calibrated (4:1 accuracy ratio). Record the certificate number, expiration date, and last-NIST-cal date on this form — CRC inspectors specifically check that these fields are populated and current.

What do we do if equipment is found out of tolerance?

Take the equipment out of service immediately and tag 'Do Not Use.' Complete a retrospective impact assessment on ALL product measured, weighed, or tested since the last passing calibration — this is the #1 calibration-related finding in enforcement actions. If product quality could be affected, quarantine affected batches and reference the deviation/CAPA number on this log. Equipment must be repaired and recalibrated with verification before returning to service.

Can calibration be performed by an external lab?

Yes, and it is often preferred for high-accuracy instruments (analytical balance, HPLC). This log accommodates both internal and external calibration. For external calibration, record the external calibrator's name and accreditation number (e.g., ISO/IEC 17025). The external calibration certificate should be attached or filed with this log.
