Phased Array Ultrasonics (PAUT) Requirements Under SAE (ex-OAE)
Procedure qualification usually requires a demonstration on a representative flawed sample, and the scan plan forms part of the approved procedure rather than a field decision. SAE (ex-OAE), enforced by Servicio de Acreditación Ecuatoriano (SAE) as the national accreditation body; Agencia de.: Employer-based certification is accepted and is the norm.
An auditor examining PAUT asks for the phased array unit, wedges, encoders, and the calibration blocks used for wedge delay, sensitivity and TCG. The body named here is real but no longer carries that name. The Organismo de Acreditación Ecuatoriano (OAE), created under the Ley del Sistema Ecuatoriano de la Calidad, was renamed and now operates as the Servicio de Acreditación Ecuatoriano (SAE); older Ecuadorian legal text and legacy contracts still say OAE, which is a frequent source of confusion at tender stage. SAE accredits inspection bodies against NTE INEN-ISO/IEC 17020:2013, the Ecuadorian adoption. Applications run through SAE's SISAC and ACREDITA SAE platforms. Accreditation is granted for five years, maintained by two surveillance evaluations at eighteen-month intervals inside the cycle, with reaccreditation applied for before expiry. In the hydrocarbon sector operators additionally require ARCH qualification, so accreditation alone does not open the gate.

| Item | What applies | Why it matters |
|---|---|---|
| Regime | Servicio de Acreditación Ecuatoriano (SAE), formerly the Organismo de Acreditación Ecuatoriano (OAE) | Enforced by Servicio de Acreditación Ecuatoriano (SAE) as the national accreditation body; Agencia de Regulación y Control de Hidrocarburos (ARCH), re-established by Decreto Ejecutivo 256 of 8 May 2024 under the Ministerio de Energía y Minas, for hydrocarbon-sector qualification of inspection companies |
| Method | Phased Array Ultrasonics (PAUT) | Needs its own procedure and its own qualified personnel |
| Procedure approval | The employer's Level III, qualified in this method | The signature an auditor traces |
| Other methods in scope | UT, RT, MT, PT, VT, ET | Each needs separate qualification |
| Renewal | SAE accreditation runs for five years and is maintained by two surveillance evaluations at eighteen-month intervals within the cycle; reaccreditation must be applied for before the cycle expires. Scope extension is available at any point on demonstration of conformity, and accreditation can be withdrawn where non-compliance affects technical competence or the quality of results. ARCH qualification runs on its own cycle set by the agency and must be tracked as a separate diary item; firms routinely lose work by keeping one current and letting the other lapse. | Applies to the personnel certification behind this method |
Does SAE (ex-OAE) require a separate procedure for PAUT?
Yes. Every method in scope needs its own written procedure, approved by someone qualified in that method, describing technique, equipment, calibration, scanning or coverage, acceptance criteria and reporting. A single combined "NDT procedure" covering several methods is a finding under every regime that names procedures individually.
Who can approve a PAUT procedure under SAE (ex-OAE)?
A Level III qualified in PAUT. Because SAE (ex-OAE) accepts employer-based certification, that Level III may be contracted rather than employed — but their own qualification must cover PAUT, and an auditor will check that before accepting the signature.
What PAUT records does a SAE (ex-OAE) audit sample?
The approved procedure, the technician's PAUT certification on the date of work, and the equipment evidence — the phased array unit, wedges, encoders, and the calibration blocks used for wedge delay, sensitivity and TCG. The auditor works backwards from a finished job, so every item has to reconcile with the report and its stated acceptance criteria.
What is the most common PAUT finding at audit?
Data acquired outside the scan plan the procedure qualified, or encoder position not recorded. It is a records failure rather than a technique failure — the examination was performed correctly and the evidence supporting it cannot be produced, which under SAE (ex-OAE) is recorded the same way as not having done the work.
Can a technician certified elsewhere perform PAUT under SAE (ex-OAE)?
Not automatically. Employer-based certification ends when the holder leaves, so the new employer must certify them under its own written practice. Prior training and documented experience transfer as evidence; the certificate itself does not.
What equipment evidence does PAUT need under SAE (ex-OAE)?
Calibration status traceable to the day of use, covering the instrument and its accessories — probes, cables, blocks and reference standards for ultrasonics; sources and densitometers for radiography. An in-calibration instrument with an out-of-calibration reference block fails the same way as an uncalibrated one.
How do PAUT requirements differ from the other methods in SAE (ex-OAE)?
Scope, qualification and evidence are method-specific, so the differences are real rather than administrative. SAE (ex-OAE) also covers UT, RT, MT, PT, VT, and each carries its own procedure, its own personnel qualification and its own equipment evidence.
Personnel certification for PAUT
Employer-based certification is accepted and is the norm. Ecuador has no verified accredited domestic body certifying NDT personnel to ISO 9712, so technicians 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 NDT procedures and certify Level I and II staff. The constraint sits on the other side of the transaction: inside a SAE-accredited inspection body, personnel competence must be demonstrated to the assessor against NTE INEN-ISO/IEC 17020:2013, meaning training, formal authorisation, witnessed performance and ongoing monitoring records. An SNT-TC-1A card on its own is not sufficient evidence at a SAE witnessing evaluation.
