The TL 9000 goes beyond the ISO 9001 standard, adding more than 90 telecom requirements and measurements that apply to hardware, software and/or service. It focuses on supply chain directives in the telecom industry.
QuEST Forum is responsible for the governance and maintenance of TL 9000 requirements and measurements.

EXFO is a proud supporter of ISO/IEC 17025 (General Requirements for the Competence of Testing and Calibration Laboratories). The ISO 17025 standard outlines the general requirements for testing and calibration laboratories. EXFO uses this standard to improve our ability to consistently produce valid results.
Calibration at EXFO are performed using standards traceable to national metrology institutes such as:

ISO 17025 purports that the user is responsible for determining the recalibration date according to the actual use of the instrument. There are a number of factors that affect instrument performance during operation such as the environmental conditions to which it may be exposed and whether or not the user follows proper connection recommendations. All of these elements must be taken into consideration when determining the appropriate calibration interval of the particular EXFO instrument.
In order to ensure appropriate calibration follow-up, EXFO has applied a special label to instrument; this label complies with the ISO 17025 standard and indicates the previous and next calibration verification dates. However, until the required empirical data has been collected, EXFO recommends that the next calibration date of an instrument be established according to the following equation:
In order to ensure that EXFO test and measurement instruments conform to the published specifications following this date, calibration may be carried out at the EXFO plant, or, depending on the product, at an EXFO Service Center.
In keeping with its commitment to offer its customers high-quality and reliable products that surpass published specifications, EXFO has undertaken to ensure that the storage period between calibration and product shipment does not have an adverse effect on the performance of the products.
Following a detailed analysis of those factors arising from storage that might potentially degrade the calibration, EXFO guarantees that the storage period indicated below will not affect the performance of the products or the recommended operation time period before requiring calibration verification:
