Examination Records for Pemex proveedores / NRF
Pemex proveedores / NRF names this requirement as "Records evidencing the level and supervision rules — who performed the examination, who supervised, and who interpreted and approved the result". The employer's Level III owns it, alongside the certification scheme rather than replacing it.
The finding auditors record against this document is: Level 1 technicians performing examinations without documented direct Level 2 supervision. Pemex publishes more than most national oil companies. The padrón de proveedores y contratistas is a public registry described on pemex.com, and the Normas de Referencia (NRF) and the newer PEMEX-EST technical standards are published as downloadable PDFs on the same site, issued by the Comité de Normalización de Petróleos Mexicanos y Organismos Subsidiarios and applied as mandatory in Pemex acquisitions and service contracting. Registration information is transferred to SISCeP, Pemex's electronic contracting platform, and suppliers are told the registration is theirs to keep current — updated at least once a year. What Pemex does not publish is the internal evaluation scoring, weighting or any pre-approved vendor list for inspection services.
Source: Pemex's public supplier pages on pemex.com — Relación con proveedores, Registro de proveedores, Requisitos for national suppliers, Proceso de registro, and the Padrón de proveedores y contratistas transparency page — together with Pemex's 'Guía rápida para el registro y evaluación de proveedores y contratistas', for the registration steps, required corporate and tax documents, the annual update duty and the transfer of registration data to SISCeP. Normas de Referencia and PEMEX-EST standards are published at public pemex.com URLs under procura/procedimientos-de-contratacion — examples confirmed to exist there include NRF-193-PEMEX-2014, NRF-065-PEMEX-2014, NRF-010-PEMEX-2014, PEMEX-EST-IC-274-2018 and PEMEX-EST-TD-142-2017 — and are issued by the Comité de Normalización de Petróleos Mexicanos y Organismos Subsidiarios. Important limitation, stated plainly: the pemex.com host refused connections from this environment on 21 August 2026, so the NDT personnel requirements attributed here to Pemex NRFs were read from secondary summaries of NRF-193-PEMEX-2014 rather than from the primary PDF. For that reason no NRF clause numbers are quoted anywhere in this entry, and the specific NRF or PEMEX-EST cited in a given tender should be downloaded and read before relying on the detail. Verified 21 August 2026.
| Item | What applies | Why it matters |
|---|---|---|
| Regime | Pemex supplier and contractor registration and the Normas de Referencia / Estándares Técnicos technical requirements | Enforced by Petróleos Mexicanos (Pemex); technical standards issued by the Comité de Normalización de Petróleos Mexicanos y Organismos Subsidiarios |
| Document | Examination Records | the general, specific and practical examination papers and results behind each certification |
| Owner | the employer's Level III | The signature an auditor traces back |
| Where it is checked | On award, demonstrate personnel qualification and certification and procedure compliance against the cited standards throughout execution. | Usually against a sampled job, not in isolation |
| Common failure | NDT personnel presented with employer-issued certificates where the cited NRF requires ISO 9712 or NMX-B-482-CANACERO-2016 certification | The gap between the manual and the job file |
What must a examination records contain under Pemex proveedores / NRF?
It has to satisfy Pemex proveedores / NRF as Petróleos Mexicanos (Pemex); technical standards issued by the Comité de Normalización de Petróleos Mexicanos y Organismos Subsidiarios enforces it: the general, specific and practical examination papers and results behind each certification. 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 examination records for Pemex proveedores / NRF?
The employer's Level III. This regime requires central or third-party certification, so the signature works alongside the scheme rather than substituting for it.
How does a Pemex proveedores / NRF 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 Pemex proveedores / NRF records be kept?
Pemex states that keeping the registration information current is the supplier's responsibility and that it should be updated at least once a year. Pemex does not publish a single uniform validity period for supplier registration across all categories, so no interval should be quoted to a client without checking the current registration rules on pemex.com. On the technical side the operative mechanism is revision control rather than renewal: NRFs are revised and reissued by the Comité de Normalización, with newer editions cancelling and replacing earlier ones, and PEMEX-EST standards have been issued alongside them since 2017-2018 — so the edition cited in the tender governs. Personnel certificates renew on their own scheme's cycle; ISO 9712-based certification is typically five years. 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 Pemex proveedores / NRF?
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 Pemex proveedores / NRF 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: NDT personnel presented with employer-issued certificates where the cited NRF requires ISO 9712 or NMX-B-482-CANACERO-2016 certification

Personnel certification context
This is where Pemex diverges sharply from baseline Mexican practice, and it is the argument that sells. NOM-020 accepts 'personal certificado' under NMX-B-482 or an equivalent, which leaves room for an employer written practice; published Pemex reference standards are stricter, requiring NDT personnel to be qualified and certified to ISO 9712 or to NMX-B-482-CANACERO-2016, with ISO 11484 cited as the applicable route for certain steel-product scopes, which follows a different qualification model. Level rules apply: Level 1 works only under direct Level 2 supervision, and interpretation of results is issued by Level 3, or by Level 2 with Level 3 approval. An outsourced Level III must personally hold certification under the scheme the contract cites.
