API Monogram

API Monogram

Every day, around the world, the oil and natural gas industry relies on equipment and products identified by the API Monogram to get the job done right.

Designed for manufacturers of production equipment, drilling equipment and now, refinery equipment, the API Monogram Program lets companies show the world what they’re made of.

Global demands and an increasingly competitive business environment in the oil and natural gas industry have created new measures by which organizations must demonstrate their abilities.

API is committed to maintaining the highest level of confidence in its certification and/or licensing activities by providing impartial and objective assessments of its client’s management systems. This commitment is supported by processes that manage conflicts of interest, ensure personnel competence, maintain confidentiality of information while promoting openness, and enable communication with all stakeholders.

Our Goal is to provide the best available solution to make the system and competence of an organization to achieve its desired goal by our consultancy and training expertise, in turn, creates value for customers, shareholders, and employees.

To discuss in detail on our certification process, contact us at admin@vegascg.com. We will send you the techno-commercial proposal.

  • Organizations applying for licensing under the API Monogram Program must develop and maintain a quality manual that describes their quality management system and how it conforms to the requirements of API Spec Q1.
  • Organizations participating in the API Monogram Program must also demonstrate continued ability to meet the technical requirements identified in the applicable API product specification(s).
  • Companies applying for API Spec Q1 / API Q2 Registration must have quality manuals and quality management systems in conformance with API Spec Q1
  • Before submitting an application to API, organizations must have had a quality management system in place for at least four months. This includes performing and documenting an internal audit and management review by the applicable standard.
  • Submit the completed application forms, application fee, and the quality manual (if applicable), and the API Spec Q1, 9th Edition Conformity Matrix and the API Spec Q2 Conformity Matrix. The quality manual must be written in English.
  • API will review the application forms and the quality manual (if applicable). Should application forms be incomplete, and/or should the quality manual be out of conformance with requirements, API will provide comments?
  • For those applying for an API Monogram License, once the application package, the quality manual and the API Spec Q1, Q2 Conformity Matrix are accepted, API will schedule an on-site audit. Audits include verifying the organization’s conformance.
  • Those applying for certification to ISO 9001, API Spec Q1, API Spec Q2, ISO 14001 and OHSAS 18001 may undergo a Stage 1 audit, Stage 1 audits are normally performed on-site and require organizations to provide the auditor with documents for review.
  • Stage 2 audits are performed on-site and include verifying the organization’s conformance with API Spec Q1, API Spec Q2, ISO 9001, ISO 14001 and OHSAS 18001.
  • API will make the certification decision on the basis of an evaluation of the audit findings and conclusions, and evidence of effective implementation of corrective actions by the organization (if required)
