Tera Berlaku — The certificate expires whether or not anyone reads it
An Indonesian editorial project examines what happens when factory instruments keep producing readings after their calibration certificates expire.
- For
- Laboratories and factory measurement managers
- Worth noticing
- A sample register shows three of six instruments usable, with two lapsed certificates and one certificate missing.
Field notes
The page organizes its argument around a sample instrument register covering scales, gauges, a fuel dispenser, a flow meter, and a temperature probe. Its displayed statuses include an 18-month lapse, a three-month lapse, and one missing certificate; the page says determining the situation took an auditor two hours. Tera Berlaku describes itself as privately held in Indonesia and explicitly says it does not perform calibration, accredit laboratories, issue certificates, or verify third-party measurements.
