WYAB Strategy on the Development
The WYAB Strategy on the Development of the Extent of Authorization provides a structured and efficient framework for accredited testing laboratories and inspection bodies seeking to expand their scope of accreditation. In an increasingly competitive and quality-driven environment, organizations must continuously evolve by introducing new testing methods, upgrading technical capabilities, and entering new inspection fields. This strategy ensures that such expansions are carried out systematically while maintaining compliance with internationally recognized standards such as ISO/IEC 17025 for testing laboratories and ISO/IEC 17020 for inspection bodies. These standards emphasize technical competence, reliable methodologies, and robust quality management systems, which are essential for ensuring consistent and credible results.
Under this strategy, organizations can request an expansion of their accreditation scope at any time during the validity of their certification. The process begins with the submission of a formal application detailing the new tests, inspection fields, or technical capabilities to be added. Supporting documentation such as test methods, equipment calibration details, staff training records, and sample reports must be provided to demonstrate readiness and competence.
WYAB carefully evaluates these submissions and determines whether an on-site assessment is necessary. For expansions that involve entirely new or unrelated fields, a comprehensive on-site evaluation is typically required to verify the organization’s ability to perform the new activities. In contrast, additions that are closely related to existing accredited services may be approved through document-based review, enabling faster processing, often within 25 days.
A key component of the strategy, particularly for inspection bodies, is the requirement for witnessed inspections. This involves a WYAB assessor observing actual inspection activities to ensure that procedures are correctly implemented and that personnel demonstrate the required level of expertise. However, WYAB also offers flexibility by allowing conditional approvals when immediate witnessing is not feasible, thereby supporting organizations in demonstrating their capabilities to potential clients.
Ultimately, the WYAB strategy promotes continuous improvement, technical excellence, and market competitiveness. By facilitating structured scope expansion, it enables organizations to meet evolving client demands, enhance their credibility, and access new business opportunities while maintaining the highest standards of quality and compliance.

• Give an example of review reports or agendas for the new field,
• Give any material data (preparing, faculty affirmation, staff aptitude, important information) relating to the new examination field.
Noticed Examinations
The expansion of another field of investigation by and large expects that the assessment body plan an examination that will be seen by an WYAB assessor before that kind of investigation can be added to the extension. In certain occasions, another field of examination can be added to the degree forthcoming the booking of an evaluation to be seen by WYAB. WYAB perceives the requirement for examination organizations to have the option to exhibit their capacities to possible clients previously they may really have a client in a specific field.
WYAB will really bend over backward to work with development of your degree on the off chance that a practical review system has been given and the examination office has given proof of preparing, work force confirmation, staff mastery or other data showing that it has the capability to complete the investigation. The length of time expected to finish development of your degree is subject to giving the above mentioned data with respect to strategies and staff, and the planning of a noticed assessment.
Scope extensions that don’t need nearby evaluations can normally be handled in 25 days or less. All costs and costs connected with scope extensions will be the obligation of the examination organization according to the WYAB standard expense plan for review organization license.
