1. Statutory Context: Measurement Equipment Quality
Under EU CBAM (Implementing Reg 2025/2547 Annex III and Reg 2025/2546 Article 5) and ISO 14064-1:2018:
All measurement devices used for billing or activity quantification (gas flowmeters, fuel weighbridges, continuous emission monitors CEMS, electrical revenue meters) must have documented, valid calibration records.
Data collected from uncalibrated instruments is flagged during third-party verifier audits, potentially disqualifying primary data.
2. Step-by-Step Calibration Management
Step 2.1: Open Facility Source Stream Detail
Navigate to FacilitiesSource Register.
Select your plant and click the specific equipment tag (e.g.
MTR-GAS-001 - North Boiler Main Flowmeter).Step 2.2: Enter Calibration Record
Click + Log New Calibration Certificate.
Enter:
Calibration Date: (e.g.
2026-01-15)Calibration Agency / Metrology Lab: (e.g.
National Metrology Lab Services)Certificate Number: (e.g.
CAL-2026-NMLS-8821)Calibration Validity Period: (e.g.
12 Months / Expiry: 2027-01-14)Uncertainty Margin (%): (e.g.
± 0.5%)Upload the signed laboratory calibration PDF certificate.
Step 2.3: Calibration Alert Thresholds
- Green (Valid): Expiry date is > 30 days away.
- Amber (Warning): Expiry date is within 30 days. The system alerts the plant manager and displays non-blocking warning banners on data entry forms.
- Red (Expired): Instrument calibration is expired. Monthly readings flagged with audit risk warnings.
