Equipment Calibration Records for INACAL / OSINERGMIN
INACAL / OSINERGMIN names this requirement as "Equipment calibration certificates traceable to INACAL's national metrology service". The equipment custodian owns it, and a contracted Level III can author and sign it.
The finding auditors record against this document is: The firm holds INACAL accreditation but is not entered in OSINERGMIN's Registro de Empresas Inspectoras, so the hermeticity certificates it issues are rejected on supervision. Peru is the clearest regional case of accreditation made compulsory by regulation rather than chosen for marketing. INACAL's Dirección de Acreditación accredits inspection bodies against NTP-ISO/IEC 17020, using application form DA-002 filed through INACAL's management platform, with the fee calculated on the number of procedures in scope. OSINERGMIN then layers a sector registry on top. Under Decreto Supremo N° 001-2022-EM, periodic hermeticity inspection of buried tanks and piping storing liquid fuels and OPDH may only be performed by inspection bodies accredited by INACAL and entered in OSINERGMIN's Registro de Empresas Inspectoras, with the inscription procedure approved by Resolución de Consejo Directivo N° 151-2024-OS/CD. Without both, the certificate the site needs has no standing.

| Item | What applies | Why it matters |
|---|---|---|
| Regime | Instituto Nacional de Calidad (INACAL) Accreditation and the OSINERGMIN Registro de Empresas Inspectoras | Enforced by Instituto Nacional de Calidad (INACAL), Dirección de Acreditación, as the national accreditation body; Organismo Supervisor de la Inversión en Energía y Minería (OSINERGMIN) as the energy and mining regulator; Ministerio de Energía y Minas (MINEM) as the rule-maker |
| Document | Equipment Calibration Records | the traceable evidence that every instrument was in calibration on the day it was used |
| Owner | the equipment custodian | The signature an auditor traces back |
| Where it is checked | For regulated fuel work, apply separately to OSINERGMIN for inscription in the Registro de Empresas Inspectoras under RCD. | Usually against a sampled job, not in isolation |
| Common failure | The firm holds INACAL accreditation but is not entered in OSINERGMIN's Registro de Empresas Inspectoras, so the hermeticity certificates it issues are rejected on supervision | The gap between the manual and the job file |
What must a equipment calibration records contain under INACAL / OSINERGMIN?
It has to satisfy INACAL / OSINERGMIN as Instituto Nacional de Calidad (INACAL), Dirección de Acreditación, as the national accreditation body; Organismo Supervisor de la Inversión en Energía y Minería (OSINERGMIN) as the energy and mining regulator; Ministerio de Energía y Minas (MINEM) as the rule-maker enforces it: the traceable evidence that every instrument was in calibration on the day it was used. The test is not completeness on paper but traceability — an auditor picks a finished job and works backwards to this document, so anything it claims must be demonstrable on that job.
Who signs the equipment calibration records for INACAL / OSINERGMIN?
The equipment custodian. Because this regime accepts employer-based certification, that role can be filled by a contracted Level III rather than a staff appointment, provided they are qualified in the methods they sign for.
How does a INACAL / OSINERGMIN auditor test this document?
By sampling. They take a completed job, find the technicians and equipment used, and trace each back through this document to the evidence behind it. A document that reads well but cannot survive that trace is the most common finding across every regime, not just this one.
How long must INACAL / OSINERGMIN records be kept?
INACAL does not publish the accreditation term or the supervision interval on its public accreditation pages, so confirm both in the current accreditation criteria before committing to a client; do not quote a number from another country's practice. What is fixed sits on the regulated side. For buried tank systems, the first hermeticity certificate is required before the system enters service, and thereafter the periodicity is set by the Índice de Riesgo assessment carried out for that specific installation. The inspection report must be submitted to OSINERGMIN within thirty calendar days of the test, and the hermeticity test itself must detect a leak rate of at least 0.1 gallons per hour (0.3785 litres per hour). Retention is set by the regime and by the client contract above it, and the longer of the two governs. Firms that set one retention period for everything and document it fare better at audit than firms tracking different periods per record type and losing track.
Does a generic template satisfy INACAL / OSINERGMIN?
No. A downloaded template describes a generic firm, and the first question an auditor asks is whether the document describes THIS firm — its methods, its equipment, its people, its actual workflow. Templates are a starting structure; the content has to be the firm's own or the trace fails immediately.
What happens if this document is missing at a INACAL / OSINERGMIN audit?
It is a finding, and depending on the regime it can suspend the certificate rather than merely generate a corrective action. The related finding auditors record most often is: The firm holds INACAL accreditation but is not entered in OSINERGMIN's Registro de Empresas Inspectoras, so the hermeticity certificates it issues are rejected on supervision

Personnel certification context
Employer-based certification is accepted, largely because Peru offers no verified alternative. INACAL accredits certification bodies for persons under NTP-ISO/IEC 17024, but no Peruvian body certifying NDT personnel to ISO 9712 could be verified in INACAL's accredited directory. Peruvian technicians therefore hold employer certification written against ASNT SNT-TC-1A, or ISO 9712 certificates issued abroad. An outsourced Level III can sign the written practice, approve procedures and certify Level I and II staff. Note the separate statutory track: tank inspection certification must come from an engineer holding a current API 510 authorisation or from an accredited inspection body, and an ASNT Level III certificate does not substitute for that.
