Quality Manual

The Quality Manual is top tier of our documentation system, and is designed to define the Quality Management System, establish responsibilities of the personnel affected by the system, and to provide processes and procedures for all activities comprising the quality system. In addition, the Quality Manual is utilized for the purpose of informing our customers of the quality system, and what specific controls are implemented to assure quality service delivery.


The manual describes the Quality Management System, and is divided into eight main sections. Sections 1 covers the Scope, Section 2 covers Normative Reference, Section 3 covers Terms and Definitions, while Sections 4-8 are modelled on the sectional organization of the ISO 9001:2008 and API Specification Q1/ISO TS 29001:2007.


The manual is supported by standard operating procedures (SOPs) and work instructions which are the third and fourth level of our Quality Management System documentation. Relevant SOPs are listed in this Quality Manual. The fifth level of our Quality Management System documentation consists of production, services, testing and inspection documents, forms, specifications and records developed by each operating unit. It is issued on a controlled copy basis to all internal functions affected by the Quality Management System and an uncontrolled copy basis to customers and suppliers and other external parties.

At ESL, We Combine Quality Management System Requirements with Products Requirements to achieve customer satisfaction.
