TL 9000 – Telecommunications quality management

Assure buyers that you have processes in place ensuring consistent quality across products and services.

A standard specific to the telecommunication industry, TL 9000 defines requirements central to design, development, production, deployment and maintenance of telecommunications products and services.  Built on the ISO 9001 quality management system standard, the standard is designed to meet industry supply chain requirements. In addition, it provides a system for measuring and tracking performance and improving results.  

Certification to TL 9000 provides assurance to any buyers or other stakeholders that your products and services are dependable. 

What is TL 9000

Developed to drive industry consistency, TL 9000 helps companies meet the supply chain quality requirements of the worldwide telecommunications industry. The standard aims to help the industry achieve the following goals:

  • Define effective cost and performance-based measurements to guide progress and evaluate the results of QMS implementation
  • Drive continual improvement and enhance customer relationships
